DRAFTING

The Drafting application is designed to allow you to produce and maintain industry standard engineering drawings directly from the 3D model or assembly part.

The 3D drafting process in NX The following illustrates the general process for creating a drawing from an existing 3D model This overview is not intended to give a detailed description of specific functions or operations. Details are addressed in later sections of this document.

Set your drafting standard and drawing preferences Before creating a drawing, it is recommended that you set the drafting standard, drafting view preferences, and annotation preferences for the new drawing. Once set, all views and annotations will be consistently created with appropriate visual characteristics and symbology.

Page 3: Drafting

Create a new drawing The first step in creating a drawing is to make a new drawing sheet either directly within the current work part, or by creating a non-master drawing part that contains the model geometry as a component.

Add views NX enables to you create a single view or multiple views at the same time. All views are derived directly from your model, and can be used to create other views, such as section and detail views. The base view determines the orthographic space and view alignment for all projected views.

Add annotation Once you have placed the views on your drawing, you are ready to add annotations.

Annotations such as dimensions and symbols are associated with the geometry in the views. If a view is moved the associated annotations move with the view. If the model is edited, the dimensions and symbols update to reflect the change.

You may also choose to add notes, labels, and in the case of assembly drawings, parts lists to your drawing

Page 4: Drafting

A completed drawing can be plotted directly from NX, or the part containing the drawing can be used directly by manufacturing to fabricate the part.

The 2D drafting process in NX The following illustrates the general process for creating standalone 2D drawings. NX provides support for two basic 2D approaches:

Non-view based approach — Applying 2D geometry directly to the drawing sheet.

Drawing-view based approach — Using drawing views to manage 2D curves and the resultant 3D modeling sketches.

Set your drafting standard and drawing preferences Before you create a drawing, it is recommended that you set the drafting standard, drafting view preferences, and annotation preferences for the new drawing. After you have set them, all views and annotations will be created consistently with appropriate visual characteristics and symbology. See Drafting and PMI standards overview and Drafting Preferences overview for more information. Create a new standalone 2D drawing The first step in creating a standalone 2D drawing is to create a new part file. This drawing part file does not need to reference 3D model geometry. You can use the drawing templates that do not require the reference of model geometry. See 2D: Create an empty drawing file for more information.

Add views When you use the drawing-view based approach, you can create a single empty drawing view or multiple empty drawing views at the same time. The drawing view determines the orthographic space and view alignment for all projected views, and can be used to create detail views. See Drafting views overview and Drawing overview for more information.

Page 5: Drafting

Create curves and sketches In NX, you can create sketch curves directly on the drawing sheet or in the drafting view. You can also create basic curves directly in a view in the expanded mode. See Methods for creating 2D curves in Drafting for more information. In the drawing-view based approach, the Project to View command simplifies 2D design by projecting curves from one view onto other views with appropriate orientations.

In the non-view based approach, NX enables you to use infinite lines to help you create and align 2D geometry in a drawing. See Infinite sketch lines overview for more information. Add annotations After you have placed the views on your drawing, you can add annotations.

Annotations such as dimensions and symbols are associated with the geometry in the views. If a view is moved the associated annotations move with the view. If the model is edited, the dimensions and symbols are updated to reflect the change.

Page 6: Drafting

You can also add notes, labels, and parts lists to your drawing. A completed drawing can be plotted directly from NX, or the part containing the drawing can be used directly by manufacturing to fabricate the part.

Convert 2D designs to 3D models In the drawing-view based approach, NX provides a streamlined path to convert 2D designs to 3D models without recreating the whole geometry. Use the Copy to 3D command to project sketch and view curves from drafting views to the 3D model space as a starting point for the construction of the model geometry.

Which grid to use in the drafting environment.

Versioning and drafting objects Beginning with the release of NX 3, drafting objects are saved with the release number in which the object was created using a Drafting version algorithm. The drafting object keeps its original release number even when it is

Page 21: Drafting

loaded into a later release, and updates according to that release number. Thus, when an NX 3.0.1 drafting object is retrieved into NX 4, it still displays and updates using the rules for NX 3.0.1 objects.

As a result of this version algorithm, software fixes and enhancements that affect the display of drafting objects do not automatically affect legacy objects. For example, If there is a software fix for a dimension arrow display in NX 3.0.1, and the fix is made in NX 4, new dimensions created in NX 4 show the fix but existing NX 3.0.1 objects do not. All newly created objects always adopt the versioning rules of the current release..

Using the versioning options on the General tab you can manually force one or more legacy drafting objects to adopt the algorithms of the current NX version, and always update according to this newer version.

Note: Other areas of the software not covered by the Drafting version algorithm may change the drawing appearance. For example, in a master model approach, a change to the model's geometry can cause a change to a drawing.

For additional information, see Object versioning in the Drafting Appendix.

Additional information.

Drafting Preferences — Annotation overview Use the options on the Annotation tab to control the behavior and appearance of retained annotations.

Retained annotations Sometimes, changes to a model can cause associated drafting objects to be deleted. For example, adding blends to edges, removing features, and uniting faces can all cause existing associated dimensions to be deleted.

The Retain Annotations option allows you to control whether or not associated drafting objects are automatically deleted when a model change is made, and how they will appear if they are not deleted but instead are placed in a retained state.

Page 24: Drafting

Annotation before model change Retained annotation after model change

While in a retained state you may reattach the drafting objects or section lines to the desired geometry by editing the associativity of the drafting object and section line. After reattachment, drafting objects and section lines are reset to their original color/font/width, and any existing section views are updated.

Retained Drafting Object Characteristics

Retained drafting objects are not selectable for most Drafting operations. However, the can be deleted, hidden, and reassociated to the model. This behavior also pertains to any drafting objects that are associated to a retained drafting object.

Retained drafting objects will not update until they are reassociated to the model. However, positional operations such as Move View , Align View , and Edit View Scale/Angle will attempt to adjust the object's position and appearance for the sake of consistency.

When the Retain Annotations option is selected and a drafting object with multiple leaders loses a leader as a result of a model change, the drafting object becomes retained. If the Retain Annotations option is not selected, the object's leader line will be removed. If the last leader is removed and Retain Annotations is not set, the object is deleted.

Like annotation with multiple leaders, boundaries and their associated crosshatching or area fill object update with model changes. If the boundary is completely deleted the crosshatch or area fill will be deleted or will become retained, depending on the Retain Annotations setting.

When features are suppressed/unsuppressed, the associated edges, silhouettes and section edges are also suppressed. Any annotation associated to these edges and silhouettes will be retained or deleted, depending on theRetain Annotations setting. Retained annotation will revert to associated annotation once the feature is unsuppressed.

Section lines associated to model features will always be placed in a retained state if the feature is suppressed or deleted, regardless of the Retain Annotations setting.

Crosshatching that was created as part of a retained section view is not placed in a retained state. Instead, these objects are maintained as part of the section view update.

Sketch dimensions and positioning dimensions are not retained.

Drafting objects which are associated to objects that are not loaded, or to objects which are in a reference set that is currently not displayed, are placed in a retained state.

Drafting Preferences — Annotation options Retained Annotations

Retain Annotations Controls whether or not associated drafting objects are deleted or placed in a retained state when a model change is made.

Note: The Delete Retained Annotations option is unavailable in the Gateway application

Use control characters and blockfont characters to generate symbols In the Drafting application, you can use control characters and blockfont characters to generate symbols that are not available using a standard keyboard. These symbols can be used in objects like notes, labels, dimensions, and ID symbols.

A control character is a sequence of alphanumeric and special characters in the format <string>. In addition to creating symbols, you can also use control characters to format text in a note or label.

Blockfont is a character font supplied with NX that contains special characters, which can be used to create various drafting symbols. Blockfont characters consist of a dollar sign ($) and an alphanumeric character.

Control and Blockfont characters can be entered into several areas in the Drafting application including:

The Text Editor dialog box.

The Identification Symbol dialog box (in the Text box).

The following table shows the symbols that can be created and their corresponding characters.

Use control characters to format text

Page 28: Drafting

The following control characters are used to format text.

Blank Space <Br>

You can insert a blank space in the text string. The value assigned to the variable "r" makes one blank space; "r" times the blank character of the current font.

Line Spacing <Zr>

You can vary the spacing between lines of text by assigning a value to the variable "r". The distance from one line of text to the next is "r" times the line spacing defined for the current font. To reset spacing to the default value, enter <Z>.

Gap <Gr>

You can assign a value to the variable "r" to make the spacing between text characters "r" times the character spacing of the current font. To reset, enter G.

Character Size <Cr>

You can change the character size by assigning a value to the "r" variable. The new character size is "r" times the character size of the current font. Enter <C> to reset to the original size.

Note: Always perform a reset when using the Character Size control character along with other control characters (such as Underline, Font, etc) within a text string. Failure to do so may produce unsatisfactory results.

Color <Kn>

Annotation color is based on the color of the object . However color for text in a line may be controlled using the <Kn> control character, where "n" represents the color ID number. The color ID number for your NX session can be found by opening any color palette and noting the ID number for the color . The actual color displayed may vary depending on your background settings.

Font <Fn>

You can assign a value to the "n" variable to change the current font. "n" is a number between 1 and 14 corresponding to the font list for the part. Enter <F> to reset to the original font.

Character Line Width <Dn>

Use the "Dn" control character to change the line width of the text. "n" can be a 1, 2, or 3 and corresponds to normal, thick, or thin, respectively.

Above Line, Over Line <A>

You can draw a straight line above the usual text line. Enter <A> at the beginning of the text to start the over line and <A> at the end of the text to terminate the over line.

Underline <U>

You can draw a straight line below the usual text line. Enter <U> at the beginning of the text to start the underline and <U> at the end of the text to terminate the underline.

Subscript <L>

You can use a subscript to place a half-size character below the bottom line of the text. Use <L> at the start and end of characters to be subscripted.

Page 29: Drafting

Inclination (italics) <In>

Enter the text control <In> immediately before words you wish to incline (or italicize), with "n" as the number of degrees for the angle of inclination. Twenty is a commonly entered value; values greater than 70 render the characters unreadable. To turn the inclination off, follow the inclined words with <I>.

Superscript <H>

You can use a superscript to place a half-size character above the top line of the text. Use <H> at the start and at the end of the characters to be superscripted.

Text Continuation <N>

Placing an <N> at the end of a line indicates that the next line is a continuation of the current line. The carriage return at the end of the first line is ignored and the second line is displayed after the first one. This can be used to overcome the 132 characters per line limit.

Three-Quarter Size Fraction <Qn!d>

A three-quarter size fraction is displayed when you use <Qn!d>. Values assigned to "n" and "d" define the numerator and denominator respectively. "!" is the separation character. No control characters can be nested inside the brackets.

Full-Size Fraction <Vn!d>

A full-size fraction is displayed when you use these control characters. Values assigned to "n" and "d" defines the numerator and denominator respectively. "!" is the separation character. No control characters can be nested inside the brackets.

Two Lines Of Text <Tr!s>

"r" and "s" are two lines of text displayed one line over the other, usually positive, real numbers that cannot contain any control characters except <Rn!d> or <Qn!d> to insert fractions.

Expression Value <Xm.n@exp_name>

"X" indicates a reference to an expression. "m" indicates the minimum field width. If required, the expression value is padded with blank spaces on the left to fill the field width. If m=0 the leading zero is suppressed.

"n" indicates the maximum number of digits after the decimal point of the expression value. If n=0 the value displays as a whole number. "m" and "n" can be separated by a comma or a period depending on the decimal point separator desired.

Note: If the text is part of a dimension, "m.n" can be omitted. If it is omitted, the number of decimal places used for the dimension is also used for the expression value.

"exp_name" indicates the expression name. The expression name is case sensitive. An expression from a part that is not the current work part can also be referenced by specifying the following provided that the interpart expressions customer default is turned on.

<part name>::<exp_name>

Expression Assignment <XA@exp_name>

"A" indicates that the expression assignment statement is displayed rather than the expression value. "exp_name" indicates the expression name. The expression name is case sensitive.

Example: For the expression "p1=if(p0<2)3 else 2*p0", the <XA@p1> control character text displays as follows:

Page 30: Drafting

p1=if(p0<2)3 else 2*p0

Part Attribute <W&@attr_title>

"W" indicates a reference to a part attribute. "&" is an optional control character that specifies that the part attribute value is to be interpreted such that control character sequences display as their corresponding symbols. If the & is not present, the part attribute value displays exactly as entered. "attr_title" indicates the referenced attribute title.

Example: A reference to an attribute titled ANGLE can be displayed in either of two ways as follows:

Attribute Reference Annotation Display

<W&@ANGLE> 45

<W@ANGLE> 45<$s>

<W&COMPONENT1@ANGLE> 45 (attribute from component)

<WCOMPONENT1@ANGLE> 45<$s> (attribute from component)

Note: The Text Editor dialog box does not currently provide any automatic means of inserting the ampersand character “&”. Therefore, you must manually insert “&” after the W. Nested attribute references are not supported.

Object Attribute Identifier <W!obj_id@attr_title>

"obj_id" indicates the unique identifier of the object to which the attribute is associated.

Note: "obj_id" is not the ID number found when you choose Information →Object .

Object Attribute <W&obj_name@attr_title>

"obj_name" indicates the object to which the object attribute has been assigned. It is important to note that if multiple objects have the same name, the first object found is selected. Therefore, it is recommended that unique object names be used when object attributes are assigned.

Drawing Sheet Attributes <W@$attr_title>

The following is a list of valid control character strings for part drawing sheet attributes.

Control string Description

<W@$SH_SHEET_NUMBER> Sheet number of the current sheet

<W@$SH_NUMBER_OF_SHEETS> Number of sheets in the current part

<W@$SH_SHEET_SCALE_NUMERATOR> Numerator of the sheet scale

<W@$SH_SHEET_SCALE_DENOMINATOR> Denominator of the sheet scale

<W@$SH_SHEET_SIZE> Size of the current sheet

<W@$SH_SHEET_UNITS> Units of the current sheet

<W@$SH_SHEET_PROJECTION_ANGLE> Projection angle symbol of the current sheet

<W@$SH_MASTER_PART_NAME> Master Model drawing sheet part name

<W@$SH_PART_NAME> Sheet part name

Drafting and PMI standards overview NX provides a set of drafting standards default files that configure the appearance of specific annotation and drafting view objects in accordance with defined national or international drafting requirements. These files let you set, or reset, Drafting and PMI annotation and view preferences with minimal effort.

NX supports the following standards:

ASME

DIN

Page 31: Drafting

ESKD

GB

ISO

JIS

You can use the installed standard, set a default standard for future NX sessions, or you can edit and save any standard to create your own custom standard.

You can also import and use custom standards that you created in a previous release, in the current release.

Where do I find it? To set the standard for the current NX session

Application Drafting or PMI

Menu Tools→Drafting Standard

To set the default standard or create a custom standard

Menu File→Utilities→Customer Defaults

Location in dialog box Drafting→General→Standard tab

Using drafting standards Changing your drafting standard in an NX session You can use Tools→Drafting Standard at any time in the Drafting or PMI application to reconfigure your annotation and drafting view preferences in accordance with the selected standard.

Note that only settings with a corresponding preference are reconfigured. If a preference does not exist for a standard default setting, then that setting will not change in your current NX session. You can only change those settings by changing the drafting standard customer default and starting a new NX session.

For example, changing your Drafting standard does not affect the weld standard, which is defined by the Weld option. This option is only on the Other Symbols →Weld tab of the Customize Drafting Standards dialog box.

You can check the NX log file (Help→NX Log File ) for a complete list of default settings that are not changed after you reset your drafting standard.

Drafting standards and drawing templates When you use a drawing template to create a new drawing part, the standards associated with the template are automatically applied to your drawing. You can reset the drawing preferences by applying a different drafting standard after the drawing is created.

To use the drafting standard that is set for the NX session instead of the template standard, before you create the part, make sure the Use Settings from Standards option is set. This option is available in the Drawing tab of the Customer Defaults →Drafting →General dialog box.

Load a drafting standard 1. In the Drafting or PMI application, choose Tools→Drafting Standard .

2. From the Load From Level list, select a level.

NX saves the file using the following naming convention:

o nxX_YYY_Drafting_Standard_ZZZ.dpv

Where:

o X = NX version number

o YYY = Standard name

o ZZZ = Level

For example, if you saved a standard with a name of myISO at the User level, the file name will be:

o nx7_myISO_Drafting_Standard_User.dpv

8. (Optional) Delete the custom standard

To do this you must delete the standard's .dpv and .xsl files, then restart NX.

Note: You may need system administrator privileges to add, edit, or delete standard files.

The files are stored in the directory specified by the UGII_SITE_DIR, UGII_GROUP_DIR, or UGII_USER_DIR environment variable.

If the above variables are not used, the standards files are stored in directories pointed to by the following variables:

Variable Description

NX Drafting methods and master model technology NX provides different methods for creating drawings using processes that are optimal for your work environment.

You can use a 2D drafting process, and start from a new drawing that does not reference any 3D model geometry.

You can use a 3D drafting process, and can place your drawing directly in your assembly or part file.

You can use the master model approach to manage your model files separately from your drawing files.

3D Drafting with master model technology The product design process typically includes input from many different people using various NX applications and sharing the same model. This team-oriented approach to product design is referred to as concurrent engineering. NX's multi-file architecture, commonly called master model architecture, or master model, supports this type of environment. With the master model architecture, the team can work concurrently on a part, on a component of the part, or on the drawing for that part. The master model environment allows diverse yet interrelated design groups to simultaneously access model geometry from a common source during product development.

This concept of the master model can be used for an assembly or for a single part. For a single part, one person can detail a drawing while another concurrently modifies the model geometry. This is accomplished by creating a dummy assembly part, containing one component. Drafting is performed in the assembly part.

For example, a drafter creates a new part file to contain the drawing. The geometry of the original part is then added to the drawing file. This displays the geometry of the model and is accessible in the drawing without actually being part of the drawing file itself. The master model and the drawing reside in separate part files.

3D non-master model drawing Drawing is contained within the part

Edit the size of a drawing sheet

When modifying the drawing size, it is important to note that the drawing size changes by reducing the drawing bounds from the upper right corner, as shown in the following figure.

In some instances, when a smaller drawing size is chosen, the views may display completely outside the new drafting view bounds. If this occurs, the following error message displays:

Cannot modify drawing. Drawing size too small. This error message may display even though the drafting views may actually fit on that drawing size. To avoid this error, it is recommended that you move the drafting views toward the lower left hand corner of the drawing prior to decreasing the drawing size. If all the views are moved and the error still occurs, a larger drawing size may be necessary. Note this error message does not occur if a portion of a view or views fit within the drawing bounds.

1. Reposition all views to the lower left corner of the drawing.

Page 39: Drafting

Note: When modifying the drawing size, it is recommended that view borders be turned on by selecting the Preferences →Drafting →View→Display Borders option. This makes visible any views that may exist partially outside of the drawing bounds.

2. Do one of the following:

o Right-click the sheet node in the Part Navigator and select Edit Sheet .

o Select Edit→Sheet .

o Click Edit Sheet on the Drafting Edit toolbar.

3. In the Sheet dialog box, reduce the size of the sheet by selecting the next smaller size from the Size list.

4. Click OK to accept the new sheet size.

If your sheet contains a border template, note that while the drawing sheet border (1) changes in size, the border template (2) does not update.

You must delete the old border and either add a new border from a border template, or move the views to a new sheet with an existing border and delete the resized sheet.

The no drawing state and Display Sheet overview When you create a new drawing but do not immediately add a drawing sheet, or if you open a part while in the Drafting application but the part does not contain a drawing, you will be presented with a display of the model instead of the 2D drawing display. This is called the no drawing state. To display the 2D drawing environment you must add a sheet using the Sheet command, or by dragging and dropping a sheet template from the Resource Bar.

Display Sheet command

Page 41: Drafting

Display Sheet lets you switch from the 2D drawing display to the 3D modeling display, and is available when at least one drawing sheet is present. When Display Sheet is off, the model view is visible and all the drafting tools are available for use in the modeling view.

This command is useful if you want to manage modeling views, or create and position 2D drafting annotation such as notes and symbols in the 3D model view

Note: Any drafting annotation created with the Drafting tools while the modeling view is displayed is created as view-dependent objects only. If you want to make the annotation visible in all views, you must use the View to Model option in the View Dependent Edit dialog box to convert the view-dependent annotation to model objects.

Additionally, you can perform some basic modeling operations including:

Creating and editing curves.

Note: Unlike Drafting annotation, all added curves are model objects and will be visible in all views.

Moving and repositioning the WCS.

Managing the model views, such as replacing, rotating, and saving model views.

Page 44: Drafting

Drafting views overview Use the Drafting application to create drafting views. You can do the following:

Automatically create standard orthographic views from model views or empty views.

Create all standard-compliant views, including detailed, sectioned, break-out section, and broken view types.

Preview and edit views as you place them.

Utilize temporary helper lines to align views.

Create views with customized orientations.

Modify a base view's perspective.

Access view creation and edit options from dialog boxes, on-screen shortcut menus, or from the Part Navigator .

Base view In a 3D drafting process, the first view you place on any drawing sheet is called a base view. A base view can serve either as a standalone view or as a parent view for other views. Base views are created from model views of the part or assembly. As you position the view on the drawing sheet, a preview window lets you review, change preferences, and reorient the view before adding it to the drawing. When you add the base view, you can do the following:

Change the selected model view (TOP, LEFT, and so on).

Change the views orientation using the Orient View tool.

Change the view's scale.

Edit the style settings for the view.

Control the display of the view and scale labels.

Choose the assembly arrangement to display.

Hide or show components in the view.

Make selected components non-sectioned in the view.

You can place as many base views on a drawing sheet as you need. You can also create base views from external parts.

Page 45: Drafting

Drawing view In a 2D drafting process, the first view you place on any drawing sheet is called a drawing view. A drawing view can serve either as a standalone view or as a parent view for other views. In drawing views you can add view curves, sketch curves, annotations, and symbols. When you add the drawing view, you can do the following:

Change the view's scale.

Change the selected model view.

Edit the style settings of the view.

Control the display of the view and scale labels.

You can place as many drawing views on a drawing sheet as you need. After you place a drawing view, you can set either the Projected View command or the Project to View command to open to create new drawing views.

Projected view Projected views are based on the rules of orthographic projection. Depending on your preferences, they can either be in first or third angle projection.

In a 3D drafting process, projected views cannot be directly added to drawing sheets but must be derived as child views from an existing view. Projected views inherit their scale and hidden edge display from the parent view you select.

First angle projected views Third angle projected views

In a 2D drafting process, the Projected View command creates another drawing view with no association to the parent drawing view.

You can set the Projected View command to open after you place a base view or a drawing view on the drawing sheet or you can manually start the command at any time.

Hinge line When you select a view to project from, a hinge line and alignment arrow appear on the view. The system infers orthographic projection from the hinge line. By moving your cursor about the center of the parent view, you can orient the hinge line at any angle from it. As you move the cursor about the parent view, the hinge line snaps to 45 degree increments.

Page 46: Drafting

3D drafting process 2D drafting process

Tip: To prevent the hinge line angle from snapping, press the Alt key.

Other views After you have placed views on a drawing sheet, you can create other view types such as detail views, section views, and broken views.

Drafting view concepts The following information describes the basic concepts associated with drafting views.

Drafting views

Drafting views (also referred to as member views) are views that you add to your drawing. Drafting views are copies of model views or are 2D views created from other drafting views (such as detail, projected, and section views). Drafting views exist only on the drawing in which they are displayed. All visible objects, including all view dependent edits and view dependent geometry, contained in the model view are copied when the views are added to the drawing. If a view is used on more than one drawing, the view dependent objects and edits appear in all copies of that view.

Imported Imported is the term displayed in the Part Navigator for the model views added to your drawing. These views are important in that other views such as orthographic, auxiliary and section views are created from them. An imported view determines orthographic space on the drawing and is used as a reference to establish the alignment and scale for all subsequent projected views. The Base view command creates imported views.

View bounds

When you select a view on the drawing NX highlights its view bounds. These bounds define the area encompassing the view, and give you visual feedback on which view was selected. View bounds are automatically updated whenever the view is updated.

Page 47: Drafting

— View bounds

— Drawing boundary

Note: You may turn on or off the display of the view bounds by toggling the Preferences→Drafting→View→Display Borders option.

Parent view A parent view is an existing drafting view used as a reference to establish the projection, alignment, and location of a newly added view (child view). A parent view can be an imported model view, orthographic view, or auxiliary view. Additionally, a parent view also refers to the view from which a detail view is created.

Drafting view layer visibility

When you add a view to a drawing, it is created with a layer visibility that is a copy of the layers visible in the model view at the time the drafting view is created. For example, if only layers 1 and 10 are visible in the model view when it is added as a drafting view, then that drafting view will only display layers 1 and 10, regardless of what layers are made visible or invisible in the model view at a later time. Additionally, views created from other views inherit the layer settings of its parent view.

You can manually change the layer visibility for any drafting view at any time using Format→ Visible in View.

See Layer visibility in views for more information.

Active view

Active views are those on which you can work directly. Active views always display the model geometry inside them and update whenever the drawing updates.

Reference view

If you change an active view to a reference view, the view geometry is no longer displayed in it and a reference marker appears in the center of the view bound. Reference views will plot but cannot be worked on directly and do not update when the drawing is updated.

Anchor point

The anchor point of a drafting view is used to anchor the contents of a view to the drawing, and to keep the view or its contents from shifting about on the drawing when model changes are made. An anchor point fixes a location on the model to a particular location on the drawing.

View dependent objects

View dependent objects appear in the view in which they are created. In the Drafting application, all objects that you create in a view or on the drawing sheet are view dependent.

If you need to add objects directly in a drafting view (as opposed to on the drawing sheet), you must use the Expand command to add the objects directly in the view. Objects added in this way are only visible in that drafting view and do not appear in your solid model or in other drafting views. This command is most often used when you need to add geometry which is used to define the boundary of specific section view types, like break-out section views.

Page 48: Drafting

Drafting View Style/View Preference overview

The NX Drafting environment uses a single dialog box with a set of dynamic options to control the style of any drafting view. The same dialog box is used to create or modify the visual appearance of a view, as well as control the preference setting for the style options associated with all view types. The dialog box is called the View Style dialog box if you are creating or modifying a specific view’s appearance. It is called the View Preference dialog box if you are setting the global preferences for all view types.

The title of the dialog box, the tabs displayed in the dialog box, and the options displayed on the different tabs of the dialog box, depend on whether you are setting the style of a view or setting the preference for all views.

From this dialog box you can:

Control visual properties of the view such as how hidden lines, visible lines, virtual intersections, and smooth edges are rendered, and whether the view is displayed as a shaded or wireframe image.

Note: When creating a detail view, the view display properties of the detail are identical to the view display properties of the parent view used to create the detail. This is true regardless of the settings in the View Preferences dialog. After a detail view is created however, you may use the View Style dialog to edit the view display properties.

Set the perspective, angle, and scale of the view.

Control the visibility of the view annotation such as the view label, scale label, and centerline symbols.

Control the display of model-based annotations within the view such as PMI and GD&T.

Set the display characteristics for tracelines and thread representations in the view. Control the appearance of a section view, including the display of foreground, background, and crosshatch

elements. Control the faceted representation characteristics for base views and view boundary characteristics for

detailed views. Where do I find it? To open the View Style dialog box

Page 50: Drafting

the appropriate settings from that view and updates the corresponding options.

You can use this command in the View Preferences dialog box to set the preferences for all future drafting views. Or you can set the preferences for the drafting view you are currently creating or editing using the View Style dialog box.

Reset While the dialog box is open, reverts changed options on the current tab to the values they were before the change.

Note: When OK is selected, all changes become permanent and the Reset button cannot be used to revert the change. If you want to reset an option, you must manually change it.

Load Defaults Lets you to reset the options on the current tab to the values given in the Drafting tabs of the File→Utilities→Customer Default dialog box.

Load All Defaults Lets you to reset the options on all the tabs to the values given in the Drafting tabs of the File→Utilities→Customer Default dialog box.

OK Completes the command and closes the dialog box. This button is green because it is the default action after selections are completed.

Apply Accepts changes made and keeps the current tab displayed

Cancel Cancels any changes and closes the dialog box.

General options overview Use the General tab on the View Style and View Preferences dialog box to set general properties for views.

From this tab you can:

Set the angle and scale of the view.

Control the display of silhouette curves, view scale and label, and UV grid lines.

Control the ability to edit the view with the Reference option.

Control the accuracy of silhouette and hidden line representations.

Control the associativity of extracted edges in the view.

Control the display of render sets in the view.

Specify where all edges in the view derive their default color.

Set update and anchor point options for the view.

Display either the view orientation or the view name on the drawing displayed in the graphics window.

Extracted Edges overview Extracted Edges is an alternate way of displaying component geometry in a drafting view. Instead of the component being directly visible in the views, the system displays a 3D representation of the component’s visible edges

Associative When associative extracted edges are used, simple annotation, view edits, and the creation of detail views can be made on large assemblies without needing to completely load the assembly components. This greatly improves performance. Extracted Edges is also useful in concurrent engineering environments (master model architecture) to control changes made to the drawing when the model is frequently edited.

If Extracted Edges is applied to a view, copies of the edges in the view are stored in the displayed part. When changes are made to component parts that exist in the view, they do not affect the view until a view update is performed. The following describes the behavior of Extracted Edges and extracted edge views:

Extracted edges are not affected by any changes to components between view updates. Their display remains unchanged until the view is updated.

Model curves which are visible in an extracted edge view are associative copies and do not update until the view is updated.

Silhouettes, section edges and other drafting edges are unaffected by changes to solids between view updates. Their display remains unchanged until the view is updated.

Page 51: Drafting

New and existing annotation are attached to, and reference, extracted edges and only update when the view is updated.

View dependent edits and view dependent annotation are moved to the Extracted Edges .

Hiding an extracted edge only affects that specific extracted edge. The edge that you hide is preserved as long as the edge is associatively maintained.

Extracted edges cannot be edited using Edit→ Object Display . They must be edited using Edit→ View→ View Dependent Edit .

Extracted edges are not displayed for model edges which are not visible in the view at the time of update.

If the original edge of an extracted edge ceases to exist (for example, component removal, solid deletion, etc.) the extracted edge loses associativity and is deleted with the next view update. Any annotation that was associated to the extracted edge is retained. If however, an extracted edge becomes invisible for a reason which does not cause loss of associativity (for example, feature suppression, hidden line, blanking of the solid, and so on), the extracted edge is not deleted with the next update unless the annotation is reassociated. This state of the dropped edge is termed "suspended". The dropped edge is not visible in this state.

Non-Associative You can create and export non-associative extracted edge views.

Note: To enable the Non-Associative option, select the Allow Non-Associative Views check box on the Miscellaneous tab of the File→Utilities →Customer Defaults →Drafting →General dialog box. The Extracted Edges list will then include Non-Associative .

Non-associative extracted edge views:

Contain unassociated copies of the model edge curves.

Do not receive an Out-of-Date check.

Do not update when the model changes.

Enable you to work on your drawing independent of an associated model. You can also use non-associated views in a multi-person drawing shop. It allows drafters to work simultaneously from multiple parts and then contribute views to a single drawing sheet.

Are not selectable for Break-Out section views.

Wireframe color from face overview You can display the edges and drafting curves of drafting views in the color of the associated face or body.

If both faces of an edge are different in color from each other and from the parent body, then the edge is displayed in the color of the most forward face.

The direction of each face is determined by the normal vector at the UV mid-point of the face.

The color assigned to an edge or drafting curve can be overridden by the Hidden Line Color , Visible Line Color , and View Dependent Edit options.

Wireframe Contrast , when enabled, may amend or alter the color to improve contrast.

Page 52: Drafting

Color From Body Color From Face

Note: You may control which color is applied to an edge if the color of the faces sharing the edge is not the same. A text file containing the color precedence is used to determine which color is applied to an edge. The name of the text file must be color_precedence.txt and it must reside in UGII_ROOT_DIR. The color precedence file lists colors by name, one color per line. The color names must be in the same language as the ugcolor.cdf file.

General options Note: See Common View Style/View Preferences dialog box options for common options not discussed here.

Option Description

Parent Displays the name of the view from which the current view was created. Displays None for all Base, Standard and Drawing views.

Silhouettes Controls the display of silhouette edges in the view.

Silhouettes are displayed

Silhouettes are not displayed Automatic Update

Controls when a drafting view is updated after a change to the model is made. When selected, hidden lines, silhouettes, view bounds, section views, and section view details are updated immediately after a model change.

Tip: If the view does not automatically update when this option is set, make sure the Delay View Update option on the View tab of the Preferences→Drafting dialog box is not selected.

Scale Label Available as a View Style option only.

Controls the display of the scale label for the view.

Additional Information

Reference Sets the view from an active view to a reference view. Active views are views you can work on directly, while reference views cannot be worked on directly.

If you change an active view to a reference view, the view geometry no longer displays and a reference marker appears inside the view bound. Although the geometry in a reference view does not display on the screen, it still plots. Views which are converted to reference views do not update until they are made active again, even if the angle, scale, or hinge line is changed.

Page 55: Drafting

Active view

Reference view Anchor Point Creates an anchor point in the view so that when the model is moved, the display remains centered in the

drafting view.

Tip: Use the Automatic Anchor Point preference or customer default setting to establish whether or not an anchor point is created and located at view creation time.

Use the Anchor Point style setting to determine if an anchor point exists in a view, create one if it doesn't exist, or delete an anchor point if it does exist

Check Boundary Status

Determines whether or not a view's out-of-date status includes its boundary.

When selected, the view boundary is marked out-of-date if changes to non-solid geometry would cause the view's boundary to change when updated.

Note: View boundary checks impact performance. This option should not be selected for large assembly drawings if performance is an issue.

UV Grid Controls the display of UV grid curves for objects in views.

Note: U and V parameters must be set for an object before the grid will appear in the view.

UV Grid not selected

UV Grid is selected View Label Available as a View Style option only.

Controls the display of the view label for the view.

Additional Information

Centerlines Available as a View Preference option only.

Automatically creates center mark, circular, and cylindrical centerlines in views where a hole or pin axis is perpendicular or parallel to the plane of the drafting view.

Note: The following views are not supported:

Faceted representation views

Unfolded section views

Revolved section views

Page 56: Drafting

Use the Insert→Centerline commands to add centerlines to existing view created without automatic centerlines.

Tolerance Controls the display accuracy of extracted edge, silhouette, and hidden lines in a view using a specified chord height tolerance value. The smaller the specified value the more accurate the representation. However, smaller tolerance values cause longer update times.

Initial tolerance values of 0.0 cause NX to automatically compute an optimum chord height tolerance for the view. Changing the chord height tolerance causes the view to completely regenerate. This is done regardless of the Delay View Update setting.

Angle Available as a View Style option only.

Changes the angle of the view. The angle is computed from the positive XC axis.

Right view at 0°angle

Right view at 30°angle Scale Available as a View Style option only.

Controls the scale of the view.

Define Render Sets in View

Enables you to select existing render sets in the drawing and apply the render sets, along with the unique hidden and visible line display characteristics of each set, to the view.

Additional Information

Expression Available as a View Style option only.

Associates the view scale to the value of an existing expression.

Note: The value of the expression is displayed in the Scale box of the dialog. If you subsequently enter a new value for the view scale the expression is no longer associated to the view scale

Extracted Edges

Provides an alternative way to display model geometry in a drafting view.

Instead of the model being directly visible in the drafting views, NX displays a 3D representation of the model's visible edges. This display option greatly enhances the time to display drawings of large assemblies.

Page 57: Drafting

Options are:

None — Extracted edges are not enabled.

Associative — Extracted edges of the model are displayed and associative. Model changes will affect the display of these curves after the view is updated.

Non-Associative — Extracted edges of the model are displayed but are non-associative. Model changes do not affect the display of these curves, even after a view update is performed.

Additional Information

Wireframe Color Source

Controls whether the display of edge and curve colors in the drafting view comes from the face or solid body of the part.

Additional Information

Display Identifier

Displays either the view orientation or the view name on the drawing displayed in the graphics window to help you navigate and manipulate drawings interactively.

None — No identifiers are displayed on the drafting view of the drawing.

Orientation — Displays the view orientation displayed for one or more specific drafting views.

Name — Displays the view name displayed for one or more specific drafting views.

Name and orientation display identifiers

Note: Display identifiers are not plotted. For plotting purposes, use view labels.

Hidden Lines overview The Hidden Line tab in the View Style and View Preferences dialog box provides options for controlling the way edges and curves, hidden by geometry based on the view orientation, are displayed.

Note: Any view created from an existing view, known as the parent view, will automatically inherit the parent view's hidden line settings, regardless of how the Hidden Line options in the View Style or View Preferences dialog boxes are set. Once the view is created, however, you can change it's hidden line display using the View Style dialog box.

Hidden line option is selected, font is set to invisible

Hidden line option is not selected

Reference Edges Only

Controls the display of hidden edges with referencing annotation. When selected, and the Hidden Line Font is set to anything other than invisible, only hidden edges with referencing annotations are displayed.

Hidden lines are displayed with referencing annotation

Hidden lines are removed when annotation is deleted

Note: You must manually update the view or the entire drawing to remove a hidden line after a referencing annotation is removed.

Edges Hidden by Edges

Controls the display of edges which are hidden by other overlapping edges. When selected, edges hidden by other edges are visible and selectable, and are set to the specified color, font, and width. If not selected, edges hidden by other edges are not displayed and are not selectable.

Edges Hidden by Edges is selected

Edges Hidden by Edges is not selected

This function is useful in two ways:

When plotting, and Edges Hidden by Edges is not selected, the plotter does not draw two curves on top of each other. This is especially useful when two edges are of a different color or font.

For parts which are not likely to have edges hidden by other edges, (e.g. springs), you can increase the speed for displaying a view by selecting Edges Hidden by Edges.

Page 63: Drafting

Interfering Solids

Controls the display of hidden edges of interfering solids. When selected, a view updates more slowly.

Hidden Lines set to invisible line, Interfering Solids not selected

Hidden Lines set to invisible, Interfering Solids set to Without Interference Curves

Hidden Lines set to invisible, Interfering Solids set to With Interference Curves

Self Hidden Controls the display of edges hidden by the solid itself. When not selected, only the edges hidden by another solid are visible. Edges hidden by their own solid are not displayed. When selected, all hidden edges are displayed.

Hidden Lines set to dotted line, Self Hidden is selected

Hidden Lines set to dotted line, Self Hidden is not selected

Include Model Curves

Applies the hidden color, font and width options to curves contained in the view. This option is especially useful in drawings with wireframe curves or 2D sketch curves.

Note: For faceted representation views, only faceted topologies participate in hidden line processing. Modeling

curves are unaffected by this option.

This option will not affect splines of degree 1. If you have a degree 1 spline, a workaround is to replace the spline with polylines to obtain hidden line processing.

Small Features

Simplifies or removes the display of small features in a view. A small feature is a set of connected faces which are smaller than a specified size expressed as a percentage of the model. This option is most useful in large scale assembly drawings where it can improve print quality and speed up performance time to update views.

When a small feature is simplified, its set of faces is replaced by a loop of edges which represents the boundary between the small feature and the model.

Options are:

Page 64: Drafting

Show All — Displays all hidden lines according to the current hidden line preference settings.

Simplify — Displays features that are smaller than the specified tolerance value as a set of simplified boundary edges.

Hide — Hides features smaller than the specified tolerance value.

Use the Small Features tolerance slider to set the size percentage between 0,10 and 5 percent of the total model size.

Show All

Simplify

Hide

Note: Not all small features are considered for simplification. The boundary of a small feature must lay completely within a face of the model before the feature's display is modified.

Note: Virtual intersection curves only display if the original surfaces joined or intersected before they were blended

Adjacent Blends

Adjacent Blends helps identify or reconstruct the faces to be intersected to form the correct virtual intersection curve. Use Adjacent Blends when the model contains analytical blend faces where the face between the blends has been blended completely away. For example, adjacent cylinder faces which share a linear smooth edge.

End Gaps Enables you to control the display of visible gaps at the ends of the virtual intersection curves. The length of the gap is in drawing units and is controlled by the value set in the End Gaps box.

Virtual intersection curves with end gaps

Note: If the gap value is too large, no gap is applied to the smooth edge.

Tracelines overview Tracelines show how assembly components fit together in an exploded view. You create tracelines in the Assemblies application.

Note: See Tracelines in the Assemblies Help for details.

Shaded view overview Use the options on the Shaded tab to display drafting views in a shaded mode. Shaded views support the same functionality that is supported in wireframe views, including display and control of visible and hidden lines, silhouettes, and unique view orientations.

Note: Shaded view display is not supported for revolved and unfolded section views.

Shaded views allow people unfamiliar with drawing conventions to interpret the drawing more easily.

Fully shaded drafting views with translucency

Page 79: Drafting

Shaded view procedures

Create a shaded view Add partial shading to a drawing view

General usage notes for shaded drafting views Plotting Shaded Views

NX uses raster image capability to support plotting of shaded views. All capabilities and limitations of plotting raster images in NX applies to plotting of shaded member views.

Hence, plotting shaded views with overlapping view borders may result in an output different than the on-screen display. That is because all view borders are treated as rectangular during plotting, and so views with non-rectangular or irregular borders may obscure adjacent views.

A work around is to reposition the views before plotting to remove any potential overlap.

Edit shaded views You can edit individual drafting views to change the shaded rendering style with the View Style dialog box. NX immediately changes the view display when changes are made. Supported shaded rendering styles are Wireframe , Partially Shaded, or Fully Shaded.

Annotations on shaded views

Drafting annotations always display in front of the shaded geometry of drafting views. You can attach annotations to all edges and curves displayed in a shaded view. However, it is not possible to create text islands. That is, annotation that has a background which obscures the view.

Templates and shaded views

Drawing and sheet templates support views for all rendering styles, except Face Analysis and Studio rendering styles. If you use a template with a particular view rendering style NX creates a drawing with views rendered in that template's rendering style.

Shaded View Display

Shaded views do not support Face Analysis and Studio rendering styles.

By default, all shaded settings available in the Modeling application are inherited by geometry in drafting views with Shaded and Partially Shaded rendering styles. A shaded drafting view looks the same as the corresponding modeling view if it has the same rendering style. Any changes to shaded settings in Modeling are reflected on the display of existing and subsequently created shaded drafting views.

UV Grid on Shaded Views

UV grid curves are displayed on top of any shaded geometry in views. Note that grid curves are displayed only when both the UV Grid check box on the General tab of the View Style dialog box is selected, and UV grid values are specified for the U and V options in the Wireframe Display group of the Edit→Object Display dialog box.

View dependent control for Translucency and Partial Shading

You can set Translucency and Partial Shading for objects in a drafting view using the View Dependent Edit dialog box. These attributes affect the display only in the member view in which you apply them and take precedence over corresponding settings applied to the same objects using the Edit Object Display dialog box. These settings have no effect on the same objects display in Modeling.

Note: The Translucency option in the Visual group of the Preferences→Drafting→View

dialog box must be selected before any Modeling or View Depended Edit translucency setting will appear in any drafting view. When not selected, all shaded objects in every view of the drawing appear opaque, regardless of their individual translucency settings.

Plotting and export functionality that supports shaded drafting views is accomplished by creating and reading temporary raster images from disk. Performance, image size, and memory requirement for this operation can vary significantly depending upon the raster Image Resolution selected for the operation. Available options are Draft , Low, Medium, and High. It is recommended that the lowest image resolution that satisfies desired quality be used for shaded drafting views to support optimal plotting performance.

Page 80: Drafting

Shaded view background

The background of shaded views is transparent to allow you to place shaded views on top of other shaded and non-shaded views.

Inherited Rendering Style

A derived view inherits the Rendering Style setting from its parent view at the time of creation, regardless of the Rendering Style setting in the Shaded tab of the View Preferences dialog box. However, after you create a derived view, you can change its Rendering Style setting using the View Style dialog box.

Shaded views in Monochrome Mode

Faces in shaded views are displayed in color even when the drawing is in monochrome mode.

PMI display drafting views honor the Display PMI through Shaded Model setting that is available in the Modeling application under Preferences→PMI . This setting is stored with the part. If the check box is selected for a part, all member views of the part on a drawing display PMI through any shaded geometry.

Shaded options Description

Rendering Style Controls how member views are displayed with the following rendering style options:

Fully Shaded — Displays a drafting view completely shaded.

Wireframe — Displays a drafting view in wireframe mode without shading.

Partially Shaded — Displays a drafting view with only specified geometry shaded.

Shaded Cut Face Color

Controls the color of all cut faces in a section view.

Override Visible Wireframe Color

Uses the color you specify in place of Visible Line color, Smooth Edge color, Visible Traceline color, and Virtual Intersection color.

Override Hidden Wireframe Color

Uses the color you specify in place of Hidden Line color and Hidden Traceline color.

Page 83: Drafting

Shade Tolerance Lets you specify one of the following shade tolerances:

Coarse

Standard

Fine

Extra Fine

Ultra Fine

Custom — Enables the Custom Edge, Face, and Angle tolerances.

Custom Edge Tolerance

Specifies the upper bounds of the distance from each chord to the curve it is approximating. Also known as the Face Edge tolerance, this option is very useful when sealing gaps between faces. The value is interpreted to be in the units of the part. The behavior is the same as the identically named option available for shaded modeling views.

Custom Face Tolerance

Specifies the maximum allowable distance between the model face and the facets approximating it, expressed in the units of the part.

Custom Angle Tolerance

Specifies the maximum angular deviation between surface normal vectors at any two positions under the facet. This option has been found to be beneficial for faces with high curvature (sharp corners).

Shininess Specifies the intensity of highlights added to shaded surfaces making them appear shiny.

Two-Sided Light Specifies whether lighting should be applied to the front and the back side of shaded faces. The lighting from a light source is applied to the face that is exposed to the light source. This behavior is similar to the behavior you see in shaded modeling views. If you turn this option off, then lighting is not applied to the back faces.

Threads overview The Thread options allow you to create ANSI and ISO thread representations for both internal and external threads in drafting views. These representations are rendered from symbolic thread features created in the Modeling application.

Note: When threads are modeled, there should be no more than one thread attached to a cylindrical face at any time. See Modeling Help for more information about thread features. The standards used for the display of threads in Drafting are ANSI Y14.6 - 1978 and ISO 6410-1 - 1993

The following rules apply to threads displayed in drafting views:

Symbolic threads only display in section views when the section line intersects the threaded face close to the center of that face within a distance of 5 percent of the diameter of the threaded face.

NX supports both end view and side view orientations for all rendering options. For non-orthogonal thread orientations (e.g., TFR-ISO and TFR-TRI), NX only supports ANSI/Simplified and ISO/Simplified renderings in non-section views.

When threads are tapered, they normally display at a nominal angle of 3 degrees. This means that the display of the thread is tapered at an angle of approximately 3 degrees from the axis of the threaded face.

Note: You can modify the display angle for a tapered thread by setting the UGII_NOMINAL_DRAWING_THREAD_TAPER_ANGLE environment variable to the desired angle. For example, to set the nominal taper angle to 5 degrees, define the variable as follows:

UGII_NOMINAL_DRAWING_THREAD_TAPER_ANGLE=5

This variable can be set to any value from 0 to 45 degrees

Minimum Pitch

Controls the minimum distance, in drawing coordinates, of two points which represent crests of a thread. It is also used to control the minimum distance between a thread and it's defining geometry such as edges, silhouettes or section edges.

This option can be used to prevent lines from running together when threads with a small pitch are plotted at a small scale.

Note: Thread curves that are closer to the defining geometry than the minimum pitch tolerance may not always display. There are two ways to display these curves:

Set the minimum pitch to a value smaller than the distance from the thread curve to the closest defining geometry.

Disable the minimum pitch by setting its value to zero.

Render True Hidden Line

Increases the quality of the rendered thread so more atypical threads are correctly rendered. However, this affects the time it takes to display the view.

Override Visible Thread Color

Sets the color of the threads using the Color dialog box

Front Clipping When set, turns on a member view's front clipping plane. The Distance box controls the distance between the view's center and the front clipping plane.

Back Clipping When set, turns on a member view's back clipping plane. The Distance box controls the distance between the view's center and the back clipping plane.

Fit Planes to Extents

Calculates the front and back clipping plane values that fit outside the model extents. After the values are calculated, they are displayed in the Distance boxes. You can then click OK or Apply to update the display.

Perspective

When set, changes the default Parallel projection to Perspective projection. The Distance box specifies the distance between the view center and the clipping planes.

Caution: If you set the Perspective option for a view, you can not add crosshatch or area fill patterns to that view.

Base overview

From the Base tab, you control:

What model view is displayed in a newly created drafting view. You can display model views from the current part, or you can select model views from a different part.

Whether the geometry displayed in the drafting view is the actual geometry or a faceted representation of the geometry. Using faceted representations of the geometry increases load performance of the drawing part.

How view boundaries are determined. Boundaries are determined from the size of the model or the size of the displayed geometry.

Whether annotation in the model view is also displayed in the drafting view.

Note: This option does not control the display of PMI objects. PMI object display is controlled by the options in the Inherit PMI tab.

Faceted Representation overview The Faceted Representation option enables you to add a drafting view with a hidden line rendering of a faceted representation of an assembly, assembly component, or piece part. The advantage of a faceted representation is that it facilitates the quick update and hidden line display of a large drawing. This option is especially beneficial on drawings of large assemblies.

Note: Please note the following limits for faceted representation views:

Hidden lines are always invisible.

Current view display preferences do not apply to faceted views. However, Extracted Edges must not be selected in order to create a faceted representation.

You can annotate a faceted representation with Identification symbols or labels, regardless of whether a component is loaded or not loaded. Identification symbols that are associated to faceted representations can be updated from the parts list with the components either loaded or unloaded.

There is no quick way to determine if a view contains faceted representations. However, you can use Information →View to list the status of the Faceted Representation option for that view.

Master Model

Page 93: Drafting

Faceted representation views work best when you use the Master Model approach by creating the drawing in a separate part and adding the part or assembly as a reference set to the drawing part. See NX Drafting methods and master model technology for further information and a description of Master Model technology. If you use the master model approach, it is recommend that you create a faceted representation reference sets in the component part which you can add directly to your drawing part. For more information about the use of faceted representation with assembly drawings, see the Large Assembly Drawing topic

If you do not use the Master Model approach, the functionality exists to create faceted representation views directly from solid models. This allows you to still take advantage of adding associative Identification symbols and labels to assembly views without loading the components.

Create view-dependent annotation and transfer it to the drawing This example shows how to create view-dependent annotation in a modeling view, then transfer the annotation to both the drafting view and the drawing sheet.

1. Open a part that does not already contain a drawing and choose Start→Drafting to start the Drafting application.

2. In the Size group of the Sheet dialog box, select Use Template .

3. Select an appropriate drawing size, with no views, from the list of available templates.

4. Click OK to create the blank sheet.

Add view-dependent annotation to a model view

1. Choose View→Display Sheet to turn off the display of the drawing sheet.

Option Description

Load Available only during view creation.

Controls which part is displayed in the drafting view. Use the Browse button to locate and open other part files.

Note: While the view will update with changes to the part, once the view is placed you cannot change the displayed part. You must recreate the view if you want to change the part displayed in the view.

Faceted Representation

Enables you to add a view to your drawing that contains an approximation, also known as a faceted representation, of the model geometry or assembly components in that view. The advantage of a faceted representation is that it facilitates the quick update and hidden line display of large scale drawings, particularly large assembly drawings

Additional information.

Inherit Clipping Boundary

Inherits the model view's clipping boundary when the view is added to the drawing.

When selected, the model clipping bounds are used to create the view border. When not selected, the model view is placed on the drawing with an Automatic Rectangular Boundary.

Transfer Annotation

Controls whether or not view-dependent annotations created in a model view, are transferred to the drawing when that view is added or if they remain within the boundary of the view itself.

Note: This option does not control the display of PMI objects. PMI object display is controlled by the options in the Inherit PMI tab.

View Style/View Preference – Detail options

Note: See Common View Style/View Preferences dialog box options for common options not discussed here.

Page 99: Drafting

Inherit PMI overview Inherit PMI provides control over which PMI annotations are inherited from your model view, and how those annotations are placed on your drawings. These options can be used to leverage already defined data and avoid manually duplicating PMI from model views.

The capabilities of the Inherit PMI options include the following:

You can control which PMI annotations are inherited onto your drawing. You can also use these options to edit the inherit settings on existing views.

You can inherit PMI onto imported views, projected views, and detail views.

You can place an inherited PMI annotation directly on your drawing. It does not need to remain within the view.

You can set a customer default to automatically rearrange inherited PMI to prevent, or minimize, overlapping.

You can synchronize specified characteristics in the model view to the drafting view. For example, if you set an option to track PMI annotation placement, the drawing is marked out-of-date when you move a PMI annotation in the model view. When you update the drawing, the PMI annotation moves to its new position.

PMI does not appear backwards or upside down on drawings.

View reporting includes inherited PMI.

You can set a customer default (Drafting →General→Drawing →Allow PMI Bidirectional Edits ) so that changes you make to inherited PMI on your drawing are automatically updated on your model as well.

Restrictions and operating characteristics for inherited PMI The following restrictions and functional operation characteristics apply when displaying PMI in a drafting view:

Inheriting PMI from a base view You can only display PMI in base views, projected views, or detail views. You cannot display PMI in other view types such as section views or broken views.

Annotation preferences and scaling Inherited PMI are displayed in drafting views using the current Annotation Preferences settings, and not the preference settings applied to the PMI in the model view. The size of the PMI adjust to maintain consistency with the drawing scale.

Position and orientation Both the position and orientation of the inherited PMI relative to the geometry and each other is the same as it is in the model view. If the z-axis of the annotation points into the drawing, NX rotates the PMI so that it is readable in the view.

View boundary When the Inherit PMI onto Drawing option is not selected, inherited PMI participates in view boundary calculations. If the view boundary is set to Automatic Rectangle , NX expands the view boundary to encompass the inherited PMI when you place the view.

Inheriting PMI from the Master Model Inherited PMI supports the NX Master Model workflow practices. When you create a non-master drawing from a master part, all model views from both the non-master drawing part and the master part are available to add to the drawing. When you add any view to your drawing, NX maintains the associations back to the master model. When the drafting views are updated they pick up any changes to the PMI in model views from the master model.

Adding additional PMI to the Master Model If you add additional PMI to a model view that was previously added to a drawing with the Inherit PMI option, NX marks the drawing as out-of-date. These out-of-date drafting views are highlighted when you bring up the Update Views dialog. When you update the drafting views, all of the new PMI added to the model view are automatically added to the associated drafting view.

Editing PMI in the Model View NX tracks certain properties of PMI objects. For example, the primary nominal tolerance. These tracked properties are called semantic properties. Whenever any semantic properties change, NX marks the corresponding drawing as out-of-date. When you update the drafting view, that change propagates to the inherited PMI. PMI objects also have

Page 100: Drafting

visual properties (for example, color or text orientation). A change to visual properties of inherited PMI does not produce an out of date warning for the associated drafting view.

Note: See the Property Tool topic in the PMI Help for additional information. Editing inherited PMI in a drawing You can only make minor changes to a PMI's visual properties from the drafting view. All dialogs and user interface elements with settings that change semantic properties are unavailable in the Drafting environment. This includes the Annotation Preferences dialog, the object-action pop-up menus, the Text Editor dialog box and the Symbols dialog.

Deleting PMI in the Model View If you delete a PMI in a model view, NX marks the associated drafting view as out-of-date. When you update the drafting view, NX deletes the corresponding inherited PMI.

PMI in context NX supports PMI with respect to assembly design in context. This means NX displays both assembly and component level PMI. NX uses PMI filters to control the display of component PMI in an assembly view. When these filters change, associated drafting views will be marked as out of date. When the drafting view is updated, any changes in the filter will be reflected in the associated drafting view.

Retained PMI in the model view If a PMI becomes retained in the model view, NX marks the corresponding drafting view out-of-date. When you update that view, the inherited PMI goes into a retained state. If PMI in the model view are associative to geometry that is not in the current reference set, then the inherited PMI in the drafting view becomes retained.

Blanked PMI in the model view If you hide PMI in the model view, then inherited PMI becomes retained.

Visibility changes to PMI in the model view NX can detect the generic case when the model view annotation is unloaded, such as when the reference set changes. In such cases, the corresponding inherited PMI become retained.

There are other cases where NX may not be able to detect changes in the display of PMI, such as moving the model view PMI onto an invisible layer, performing view-dependent edits on the annotation, etc. In such cases, the synchronization capability of the inherited PMI is undefined.

Inherit PMI options

\Note: See Common View Style/View Preferences dialog box options for common options not discussed here.

Inherit PMI

None Turns off the Inherit PMI behavior for a view. If you select this option on an existing view containing inherited PMI, then the view is marked out-of-date. When the view is updated, all of the displayed PMI are removed.

From Model View Displays all PMI from the model view in the equivalent drafting vieww.

Aligned to Drawing (View Only)

Displays only those PMI contained in the model view being placed on the drawing, and whose annotation planes are parallel to the drawing sheet.

When you change to this option from None, the view is marked out-of-date. When the view is updated, only those PMI from the model view whose planes are parallel to the drawing sheet are displayed in the view.

When you change to this option from From Model View, the view is marked out-of-date. When the model view is updated, only those PMI whose planes are parallel to the drawing sheet remain. This option is more restrictive than From Model View.

Aligned to Drawing (Entire Part)

All PMI in the entire part whose annotation planes are parallel to the drawing sheet are displayed when the view is added to the drawing.

Inherit PMI onto Drawing

Places the PMI on the drawing rather than as view-dependent objects within the view.

This option is only available when the Aligned to Drawing (View Only) option or Aligned to Drawing (Entire Part) option is selected. It does not apply to checked GD&T display instances.

Note: This option is only available when you add a view to a drawing. It is unavailable when editing an existing view.

Page 111: Drafting

PMI Types Opens the PMI Types dialog box which enables you to control which PMI types are displayed in a view. By default all PMI types are selected.

Inherit GDT

Enables you to display checked GD&T display instances in a drafting vieww.

Note: Inherit GDT options are only available in the View Style dialog box while creating a new view or in the View Preferences dialog box. Once a view is created you can not edit the view and add or remove these options using the View Style dialog box.

Inherit GDT provides the following options:

None — No checked GD&T display instances are displayed in the drafting vieww.

In Drawing Plane — Displays checked GD&T display instances, which are parallel to the drawing plane, as view-dependent drawing objects when the model view is added to the drawing. If the display instance is not parallel to the drawing plane it is not displayed with the view.

From Model View — Displays all checked GD&T display instances which exist in the model view being placed onto the drawing. The display instances remain part of the model view, and retain their orientation when the view is added to the drawing.

View Label overview

View label style and preference options allow you to automatically generate associative labels for drafting views. When the view is either moved or deleted, the labels are likewise moved or deleted.

A view label consists of a prefix and a label letter. A scale label consists of a prefix and scale value. The scale value is associated with the actual scale of the view and updates when the view scale changes.

With the view label style and preference options you can:

Control the display of a view label's prefix name, letter, letter format, and letter size.

Control the display of a view scale label's text position, prefix name, prefix text size, letter format, and letter size..

You control the visibility of the view label and scale label using the View Label and Scale Label options on the General tab of the View Style or View Preference dialog box.

Section View with view label and view scale label

Like the view preferences and style dialog box, NX uses the same dialog box to both set view label preferences and edit existing view labels. You use the View Label Preferences dialog box to set preferences for new view labels, or you use the View Label Style dialog box to edit the settings of existing view labels. Different options are available in the dialog box depending on whether you are setting preferences or editing an existing view label.

Drawing layer visibility overview When you place a base view on a drawing sheet, the view displays all geometry on layers that are currently visible in your part. Projected, detail and section views inherit their layer visibility settings from their parent view. After you place a view on a drawing sheet, the layer visibility settings are always retained for that view regardless of how the layer visibility is later changed in the model. However, if you want to display or hide geometry from a drafting view after it has been created, you can modify the layer settings for the drafting view using Format→ Visible in View . Therefore each view on a drawing sheet can have its own configuration of layer visibility settings.

Drawing sheets follow the same layer visibility rules as views. Only the layers that are visible or selectable at the time the drawing is created are visible for the drawing sheet.

Use the Visible in View command to:

Modify the layer visibility settings for individual drafting views to reflect changes made in the model.

Choose the Reset to Global button to reset a views layer settings to the current layer settings of the layers in the model.

Modify the layer visibility for a drawing sheet. This controls the visibility of annotations that reside on the drawing sheet.

Modify the layer visibility of a view on the drawing sheet. This controls visibility of objects on the drawing sheet.

Control the layer visibility of a drafting view This example shows you how to control the visible layers in a drafting view before adding the view to a drawing, and after the view has been added to the drawing. The example uses a model that contains construction geometry that has been placed on separate layers from the part geometry.

1. In the Drafting application, add a base view using Insert→View→Base , or click Base View on the Drawing toolbar.

2. Click to place the view on the drawing.

Notice that the view contains all of the visible geometry in the part. That is because all layers were visible in the model view before the view was added to the drawing.

3. Delete the drafting view by right-clicking the view border and selecting Delete , or by selecting the view and

Notice that the new view only displays the model geometry and not the construction geometry.

Change the layer visibility of an existing drafting view Instead of recreating a view, you can change the visibility of layers in any existing drafting view.

1. In the Drafting application, select Format→Visible in View , or click Layer Visible in View on the Utility toolbar.

2. Select the view in the graphics window.

3. In the Visible Layers in View dialog box, make the layers that contain the construction geometry invisible by selecting each layer in the Layers list and clicking the Invisible button.

When all layers except the layers containing the model geometry have been set to invisible, click OK to update the layer visibility for the drafting view.

Page 120: Drafting

Tip: Use this method to remove the visibility of any geometry added to the model after the drafting view was created.

Reset the layer visibility of all layers in a draft ing view This example demonstrates how to use the Global Reset option to reset the visible layers in a drafting view.

1. In the Modeling application, use the Format→Layer Settings command to make only the layer containing the guitar body visible.

2. In the Drafting application, select Format→Visible in View , or click Layer Visible in View on the Utility toolbar.

3. In the Visible Layers in View dialog box, select the bottom drafting view from the list of sheet and drafting views.

Page 121: Drafting

4. Click the Reset to Global button, then click Cancel to dismiss the Visible Layers in View dialog box.

The lower drafting view has been reset to display only the layer that is visible in the Modeling application while the upper drafting view is unaffected.

Note: You may have to manually update your drawing in order to see the changes in your view.

Move/Copy View overview The easiest way to reposition a view is to drag the border of the view on the drawing sheet. Helper lines appear to assist when aligning to the top, bottom, left, right, or center of other views. You can also perform simple Cut /Copy /Paste operations on views.

Note: View and non-view types cannot be selected at the same time. For example, if you use rectangular selection to encompass a view and a note on the drawing, NX selects only the note.

The Move/Copy View command offers additional methods to move or copy views within the currently displayed drawing sheet or to another drawing sheet in the part.

Page 122: Drafting

2. Move/Copy method

3. Move/Copy options (varies by method)

Move/Copy View Tool

Move/Copy View methods include:

To a Point

Horizontally

Vertically

Perpendicular to a Line

To Another Drawing

When you copy a view, its annotation, view dependent geometry, and view dependent edits are also copied. The copied view inherits the boundary type from the original. When a view contains a view label, the label is also copied. However, the label letter is incremented when the copy is placed on the drawing.

Parent/child view relationships When you copy multiple views, parent/child view relationships between the original views are maintained in the copied views.

Example: If you copy a section view and its parent, the section line symbol is also copied in the new parent view, and the duplicate section view is a child of that view.

When you copy single views, no parent/child view relationships are created.

Example: If you copy a section view by itself a detail view is created.

If you copy a view with a section line and not the child section view, the copy view does not have a section line.

When applying view dependent edits to selected objects in a view, it is often easier to select the objects from a different view. Sometimes it may be helpful to temporarily add a view to the current drawing sheet (such as a 3D view) to assist in object selection, and then later remove the view when it is no longer needed.

Note: The default creation mode for the Drafting application is view dependent. View dependent objects, view dependent edits, and drafting annotations that appear in the drawing sheet do not appear in any of the Modeling views.

Note: View dependent edits made on Modeling views are supported only when Hidden Edges are set to Visible .

The segment that falls between the selected end point and the bounding edge appear with the new font setting. The segment that falls outside of the bounding objects remains unaffected.

Edit a segment using only one bounding object

1. Select the object to be edited where shown in the view.

This time since only one bounding object is to be selected, the place you select the object determines which side the edit occurs relative to the bounding object.

2. Select the bounding object.

The side of the segment selected in relation to its bounding object determines which portion of the segment to modify.

At this point, you may do one of two things. You may click OK to edit the object segment selected, or you may continue to select a second bounding object. If necessary, after selecting the second bounding object you may continue to select additional pairs of bounding objects to edit multiple segments on the same curve or edge.

3. Click OK.

Edit a closed curve between two bounding objects If NX cannot determine from your selection which segment of the curve you want to edit, you are prompted to indicate a point on the portion of the curve segment you wish to edit. For example, if a line or arc passes through a complete circle, and you wish to change the color of a portion of the circle, you are prompted to indicate which part

Page 156: Drafting

of the circle you want to edit. Since the line divides the circle into two parts, the color change could take place on either part. The point you indicate therefore eliminates any ambiguity.

1. Select the object to be edited.

2. Select the first bounding object.

3. Select the second bounding object.

The cue line asks you to:

o Pick portion of closed curve to apply the edit to.

Define a view boundary point Use this method to associate a Break Line/Detail view boundary with model features so that when the model changes the view boundary updates with respect to the model.

Note: You cannot use Sketch curves to define the manual boundary if you also want to define a view boundary point. Instead you must add basic curves to the drawing view. Due to the nature of sketch curves, an error will result when you attempt to define the boundary point.

1. Right–click in the middle of the view and choose Expand .

This makes the selected view the work view and the created curves will be visible and associated to the view (view-dependent).

2. In the Curve tool bar, choose Studio Spline .

3. Create break-line curves as required (1).

4. Right–click in the view and choose Expand again to close the view.

5. (Optional) Right-click the view and select Update to adjust the view boundary to completely display the curves.

6. Choose Edit→View→View Boundary .

A construction curve is displayed (1).

Page 177: Drafting

10. Choose Apply .

A second construction curve is displayed to close the loop.

11. Click on a construction curve, then drag it to shape it as required. See the example below.

12. Click the Anchor Point button.

13. Select the model feature with which to associate the anchor point.

Page 178: Drafting

An anchor point is used to anchor the contents of a detail view to the drawing. This keeps the view or its contents from shifting about on the drawing when model changes are made. In the example below, an anchor point is placed in the center of the lower left corner hole.

Note: The location of the anchor point is important since the boundary points, by default, are at a fixed offset from the anchor point. Place the anchor point on a feature which you want to remain inside the view boundary.

14. Click the Boundary Point button.

Points along the boundary curves are displayed. By default, these points are not directly associated with any points on the model, but instead are fixed at a specific offset from the anchor point.

In this example, the associativity of the three boundary points shown below will be changed.

Boundary points whose associativity is to be changed

— Boundary Point #1

— Boundary Point #2

— Boundary Point #3

— Anchor Point

15. Select Boundary Point #1.

Page 179: Drafting

Note in the Cue line that you are asked to indicate a new boundary point.

16. Choose an appropriate point on the model.

Tip: Make sure the appropriate Snap Point option is available from the Selection toolbar.

In this example, the center point of the edge curve is selected. If the edge that contains the point is later moved, the associated boundary point also moves.

Model edge is selected

— Selected edge curve

17. Click Apply to accept the new boundary point.

18. Click Boundary Point again, then select Boundary Point #2.

19. Select another edge curve close to the original boundary point and choose Apply .

20. Choose Boundary Point again and perform the same steps to associate the third boundary point to a point on the model.

21. After all boundary points are associated to the model click Apply or OK.

The view boundary is created with associative boundary points (see the following figure). When the model is later modified, the detail view updates automatically to reflect the change.

Page 180: Drafting

Break line detail view with associated boundary poi nts

In the following figure the width of both legs of the L bracket were made larger. Note that detail view boundary was updated to reflect the change.

Detail view with associated boundaries before and after a model edit

— Detail view prior to a model edit

— Detail view after the model edit is made

Note: Once you have used Boundary Point to create an associative view boundary, the curves used to make the boundary can no longer be edited using Insert→Curve . They can only be edited by using Boundary Point .

Note: Boundary points which lose their associativity are displayed in the retain color when a view update is performed.

Update Views overview

Update Views enables you to manually update selected drafting views to reflect changes that have occurred to the model since the last time the views were updated. When you update a view, selected out-of-date views are updated, and selected up-to-date views are regenerated (including all silhouettes and hidden lines).

Note: Drafting views will automatically update whenever a change takes place if the Delay View Update option on the View tab of the Preferences →Drafting dialog box is not selected. However, this can decrease overall system performance for very large models so it is recommended that you leave this option selected and manually update your views when necessary.

Items that may be updated include:

Hidden lines

Silhouettes

View bounds

Section views

Section view details

Drawings can go out of date due to any model or visibility change to solids, or any change to associative view orientation, associative view anchor point, associative view boundary curves, associative hingelines, or tracelines.

If the currently displayed drawing or any of its views are not up to date, an "Out-of-Date" message appears next to the drawing name in the lower left corner of the drawing display. This message may also appear when the drawing contains any invalid section lines.

Drawing overview

The Drawing command creates a drafting view that does not contain any geometry from the current model. The empty view is not associated to model geometry, but you can identify it as a standard view orientation (TOP, LEFT, and so on), or define the orientation with respect to the model's absolute CSYS.

There are two ways to place a Drawing view:

Center lets you create and adjust position of the view on the sheet in one selection. The resulting boundary is an Automatic Rectangle.

Corners lets you control the size of the view and its position on the sheet by specifying two diagonal points. The resulting view boundary is a Manual Rectangle.

To create view dependent geometry in the Drawing view:

Make the view the Active Sketch View and create sketch curves.

Expand the view and use the Curves toolbar to create basic curves directly in the drafting view.

You can select from any of the following view configurations: 1. Front / Top 2. Front / Right 3. Front / Left 4. Front / Top / Right 5. Front / Top / Left 6. Front / Top / Right / Isometric 7. Front / Top / Left / Isometric

You can specify the scale, center coordinates, View Style, and margins for the view sets you create. Creating standard sets also ensures consistency when defining center coordinates, margins and style within a given drawing. It encourages standardization between different drawings by creating specific sets of drafting views arranged in a consistent layout. Where do I find it?

Projected overview You can project views from an existing base, drawing, orthographic, or auxiliary view. NX automatically infers orthographic and auxiliary alignment as you move the cursor in a circular motion about the parent view's center.

Note: The Automatically Start Projected View Command option on the General tab of the Preferences →Drafting dialog box controls the automatic start up of the projected view command.

The system automatically infers:

A hinge line to use as a reference to rotate the view into orthographic space.

A vector direction that is perpendicular to the hinge line. The arrow indicates the projection direction from the parent view.

You can manually define the hinge line and also reverse the projection direction before you place the view.

Menu Insert→View→Projected

Shortcut Menu Right-click a view border→Add Projected View

Part Navigator Right-click a view node→Add Projected View

Orthographic views The Projected view command allows you to automatically create orthographic projections from existing views. To place an orthographic view onto the drawing sheet, drag the projected preview image directly to the right or left, above or below the parent view. When view snaps to vertical or horizontal alignment with the parent view, an orthographic view is created according to the projection angle of the drawing sheet. The orthographic view inherits its initial view preferences from the parent view.

Hinge Line

Orthographic Direction

Helper Line

Page 196: Drafting

Auxiliary views By revolving the hinge line to an oblique angle in the parent view, you can automatically project an auxiliary view from it.

Hinge Line

Orthographic Direction

Shaded Auxiliary Preview As you rotate the hinge line about the center of the parent view, it automatically snaps to 45 degree increments. To prevent the angle snapping, press Alt as you position the view on the drawing sheet.

Create an orthographic view When the Automatically Start Projected View Command option is selected in the Drafting Preferences dialog box, NX places you in projected view mode immediately after you place a base view on the drawing sheet. The following example shows how to create an orthographic view from an existing view.

1. Right-click an existing view's border and choose Add Projected View .

The hinge line and arrow vector symbol appear in the view.

2. (Optional) Choose any of the Projected view options or right-click and choose shortcut options as desired.

Detail overview

Page 204: Drafting

A Detail view contains an enlarged area of an already existing drafting view. The enlarged area shows detail which is not apparent in the view from which the detail was made. You can create detail views with either circular or rectangular view boundaries.

Circular and Rectangular Detail Views with label View and scale labels can be attached to the detail view as well as to the boundary in the parent view.

When you create a new detail view, this detail view is associated to its parent view. When you make changes to the parent view, these changes are immediately reflected in the detail view.

As long as the detail view is associated to its parent view, the detail view shares the curves and sketch curves of the parent. You cannot modify these curves directly in the detail view. You can insert annotations for detail view curves.

To modify the curves and sketch curves of the detail view independently of the parent, make the detail view independent of its parent. In the Part Navigator , right-click the detail view node and choose Convert to Independent Detail .

Section overview The Section view options let you create views in which some of the model geometry is removed in order to expose internal features that would otherwise be obscured in the view.

Page 210: Drafting

You begin any section view by constructing a section line symbol in an existing view. This view becomes the parent for the section view so that a true parent/child view relationship is established between the two. Once the section line symbol is completed, the section view is generated complete with associative crosshatching coinciding with the plane of the cut or cuts in the parent view. The section view can also have a view label and scale label associated with it. The section view's letter corresponds with the section line symbol letter in the parent view.

Application Drafting

Toolbar Drawing→Unfolded Point to Point Section View or Unfolded Point and Angle Section View .

Menu Insert→View→Unfolded Point to Point Section or Unfolded Point and Angle Section.

Unfolded Section view concepts You create an unfolded section view by specifying a series of points in the parent view. After all of the required points are selected, NX creates the section view by revolving the individual cut segments about the selected points onto a single viewing plane.

There are two methods for constructing unfolded section views:

Unfolded Point to Point Section

Unfolded Point and Angle Section

Note: Extracted Edges is automatically turned to Associative when Preferences →View→Section →Background is selected. Extracted edges are required for unfolded section views when Background is ON.

Unfolded Point to Point Section This option creates an unfolded section view by stringing section cuts through a series of selected model points or cursor locations in the parent view.

Segment cut points

Page 234: Drafting

Resulting section view You can use the Snap Point options to filter your point selections, however section cut segments must not be collinear or intersect.

Unfolded Point and Angle Section This option creates a unfolded section view through a series of points at specified angles in the parent view.

After you select the parent view and define a hinge line, the Section Line Creation dialog box appears. When you select the first Cut Position point, its angle appears in the Angle box.

Angle box Cut angle values Cut angles are based on absolute angle values. The first cut angle is always parallel to the hinge line and each successive cut angle defaults to 90 degrees from the previous one. To change the cut angle at the specified point, type a value in the Angle box.

Page 235: Drafting

In the example above, you can use various angle values for each cut position and achieve equivalent results. The following table lists the alternate angle values that can be used to construct the section line symbol in the example.

Point Angle at point Alternate angle

1 0 180, –180

2 143 -37

3 0 180, –180

Each cut angle can be positive or negative but must not be greater than 180 or less than –180 degrees.

Oriented Section overview Use the Oriented Section view command to create true 3D or 2D section cuts. The 3D Cut option creates a true 3D section cut from a 2D view. The 3D section line displays like a simple 2D section line, but what is created is a true 3D section cut based on the normal, binormal, and tangent vectors derived from a point on a curve.

The difference between the normal 3D Cut and the 2D Cut is that the cut vector for a 2D cut is defined to be the view normal. In a 3D cut, the cut vector is inferred to be the binormal of the curve at the selected position along the curve.

The section view is projected orthogonally (that is, above, below, left, or right) from the parent view.

The section view is oriented so that the cut lies on the view plane.

You can rapidly create a true section cut view without having to specify all the steps required to produce the same view using the Pictorial Section view command.

Section Line Creation dialog box This dialog box contains options for creating a 2D or 3D oriented section view.

Option Description

Section line type 3D — Specifies a 3D section cut line. You can select any point attached to a curve or edge, and the hinge line is automatically determined to be normal to the surface, and is oriented perpendicular to the tangent vector of the curve at the given point.

2D — Specifies a 2D section cut line. You can select any point attached to a curve or edge, and the hinge line is automatically determined to be normal to the curve projected onto the view, and is oriented perpendicular to the tangent vector of the curve at the given point.

Positioning Options

Cut Orientation — Specifies the orientation of the cut plane with respect to the view. You select a point location on a curve.

Arrow Position — Specifies the location of the arrow segment portion of a section line. The arrow segment includes the arrowhead and defines the direction of sight for viewing the section cut. Arrow segments are perpendicular to cut segments.

Cut Position — Lets you specify the location of the cut segment portion of a section line which defines a cutting plane. This is typically parallel to the hinge line.

Select Plane — Lets you define a cutting plane other than normal to the screen. By default the cutting plane is normal to the screen (that is, into the screen).

Alignment — Provides the following alignment options for the Cut Orientation and Cut Position:

None

Horizontal — Specifies the cut line with respect to the horizontal center of the view.

Vertical — Specifies the cut line with respect to vertical bottom of the view.

Value — Specifies a value for offsetting the guide line. The guide line is a horizontal or vertical line at position Value in model coordinates (aka the offset in part units from the XC or YC axis). When the point along a curve is specified for the Cut Orientation or Cut Position, this curve is intersected with the guide line to define the final point used for the cut position and/or orientation. Its purpose is to allow you to define a line “on the fly” to be intersected with the curve to form the point. When a guide line is specified, you should see a red (aka system color) horizontal or vertical line displayed in the view for visual reference.

Point Selection Defines point locations. Depending on which option you choose, the software interprets the selected object(s) accordingly.

Next Leg Controls which leg of a revolved section line you are working on. After constructing one leg of a revolved section, you can press the Next Leg button to allow you to work on the other leg of the section line. This button is only active when creating revolved sections.

Remove Last Removes the last section line creation operation.

Break-out Section overview Break-out section views allow you to see the inside of a part by removing an external region of the part. The break-out region is defined by a closed loop of boundary curves.

Page 258: Drafting

Break-out section views

Note: Please note the following exceptions:

Only the planar cut faces of a Break-out Section view are crosshatched.

You can use sketch curves or basic curves to create the break-out boundary. However, sketch curves are always applied to the 2D drawing plane. If your boundary curves need to be created in any other plane, you must expand the view and create basic curves.

Splines created by the fit method are not selectable for Break-out Section view boundaries. If you want to use splines as boundary curves for a breakout view, they must be created using Through Points or By Poles .

Curves used to define the base point cannot be used as boundary curves.

Rotated views are not selectable as candidates for a Break-out Section view.

Where do I find it?

Application Drafting

Toolbar Drawing→Break-out Section View

Menu Insert→View→Break-out Section

Create an orthogonal break-out section view 1. Expand the drafting view by right-clicking the view and selecting Expand Member View .

2. Use the Curve toolbar to create view dependent curves to represent the boundary of the break-out section.

Tip: You must first show the Curve toolbar before you can create a curve. To show the toolbar, right-click in the toolbar area and choose Curve .

Note: For break-out section views that only require a simple orthogonal break-out, it is not necessary to expand the view to add curves. Instead, you can right-click and make the view the Active Sketch View , then add sketch curves to define the break-out boundary.

Page 259: Drafting

You can either create a set of closed curves or create an open curve and let NX automatically close the boundary for you as you progress through the creation steps.

In this case a single spline has been placed in the view, marking the extent of the break-out section on the part.

3. Unexpand the drafting view by right-clicking in the background of the view and selecting Expand .

4. On the Drawing toolbar, click Break-out Section View , or choose Insert→View→Break-out Section .

Broken view concepts The Broken command allows you to create, modify, and delete foreshortened views. To create a Broken view, start by selecting a member view from the current drawing sheet. The selected view is displayed in expanded view mode. You then define a primary and one or more secondary break regions. A break region is established when you construct a closed boundary around a portion of the part that needs to remain visible in the view.

A break region's boundary consists of a combination of break curves and adjoining construction lines. Break curves are manually placed on model geometry and construction lines are rubberbanded from them as you move your cursor about the view. You select the type of break curve you want to use from the Curve Type list in the Broken View dialog box. When a boundary is completed, an anchor point is placed at the start point of the boundary. You can either accept the default anchor point location or define your own.

2. Break Curve

3. Construction Lines

When you complete the break regions, you are returned to the drawing display. The construction lines used to define the break regions are hidden in the view while the break curves remain visible throughout.

Annotating broken views Broken biews can be annotated just like any other drafting view. Since dimensions are associated with model geometry and not to positions on a drawing sheet, foreshortening a view does not affect the value of a dimension applied to it. Therefore you can dimension across one region of a broken view to another and still get the correct dimension value of the part geometry.

It is suggested that whenever possible, you create the broken view first and then annotate it afterward. Associativities to annotations are not remapped to different break regions in broken views when you add, delete, or edit them. This may cause annotation leaders or extension lines to not display correctly. This however may not always be avoidable, as in the case where model edits need to be performed after a broken view has been annotated. Since remapping does not occur for modeling edits either, some annotations in broken views may need to be reassociated or rebuilt completely after a model is edited.

Broken View dialog box Option Description

Creation Steps Creation Steps guide you through the interactive process of creating the broken view. These steps become available after you choose a drafting view.

Add Break Region – Defines a new break region boundary. A broken view consists of a primary region and one or more break regions. The primary region can be any type of member view and has an associative view boundary and an anchor point. Each break region has an associative boundary, anchor point, and positioning information.

Replace Break Boundary – Replaces an existing break region boundary. This option becomes available as soon as you define the first break region boundary. If there is only one break region boundary defined, it is automatically selected. If there is more than one break region boundary defined, select the boundary you want to replace. You now define a break region boundary the same way as if you were adding a new break region.

Move Boundary Point – Edits the individual curves of an existing break region boundary. A curve's boundary points display as circles when you pass the cursor over the curve.

Define Anchor Point – Specifies the defining point used to position a break region boundary. An anchor point specifies an associative model position as the defining point for a region. The anchor point is used to anchor the model to the drawing and to associate the boundary to the model. For break regions, the anchor point is only used to make the boundary associative to the model.

Page 288: Drafting

Position Break Region – Modifies the position of a break region relative to other region(s) in the broken view. You can use the Preview and/or Move option to drag a region to a new position or you can use one of the following Positioning Methods to position a region: Inferred, Distance, Two Regions, or None.

When you select the Position Break Region option, the Positioning Methods are unavailable until you select a break region to position. The Preview and Position option is available immediately. Once you select a region, all of the methods are available.

Delete Break Region – Deletes a break region from the broken view. If there is a primary boundary region and only one break boundary region, the break region is automatically selected. You cannot delete a primary boundary region until all break regions are removed.

Note: Only break regions that are not referenced can be deleted. .

Curve Type

Lets you choose the curve method to use to construct the next curve in the boundary being added or redefined.

Additional information

Positioning Method list.

Repositions one or move break regions relative to the primary region.

Inferred - Uses the region boundary centers to determine the relative positions of the break region and primary region. The system determines whether alignment should be horizontal or vertical based on the positions of the region boundary centers. The value in the Distance box (gap distance) determines the positioning in drawing units between the XY boxes enclosing the boundaries.

Distance - Lets you position a break region by specifying a reference region and a distance in drawing units between the regions in the specified alignment direction.

Two Regions - This option is only valid when there are two or more break boundary regions in a broken view. You select the break region to position and then select two other regions. The point of intersection defined by alignment vectors determines positioning.

None - Superimposes the break region model over the primary region so that models overlay.

Distance Value applied when either the Inferred or Distance option is used from the Positioning Method list.

Preview and Position

Previews the broken view. A directional arrow and distance value appear in the break region that can be dynamically dragged. The drag direction is parallel to the arrow direction in the view. Dragging the break region overrides the Distance value.

Create Basic Curves

Creates basic curves in the selected view. See the Modeling Help for a description of Basic Curves

Create Spline Curves

Break curve creation options There are creation options that you can use during break curve creation.

Snap Construction Lines - When selected, this option causes the end point of a construction line to snap to a vertical, horizontal, or 45 degree direction when the end point is within a system defined tolerance.

Mirror Spline - Allows you to reverse a spline 180 degrees about the axis defined by the spline's end point. You use this option while you are in rubberband mode after you select the start point and before you select the end point. This option is only available for the following predefined curves from the Curve Types list:

Simple Break

Saw Tooth Break

Long Break

Simple Tubular Break

Solid Rod Break

Solid Tubular Break

In order for the Simple Tubular Break , Solid Rod Break , and Solid Tubular Break curve types to display correctly, the concave portion of the open curve must face the interior of the break region. If it does not and you choose Apply , a Boundary Curve Validation message window provides you the opportunity to mirror the curve. Yes mirrors the curve. No closes the Boundary Curve Validation message without mirroring the curve.

Correct Incorrect Reverse Spline Ends - Reverses the direction of the curve being added to the boundary. You use this option while you are in rubberband mode after you select the start point and before you select the end point. This option is only available for the following predefined curves: Simple Tubular Break , Solid Rod Break , and Solid Tubular Break .

Spline Ends Normal Spline Ends Reversed

Spline Amplitude - Allows you to unidirectionally scale the spline in the direction perpendicular to the spline axis in the plane of view. The Spline Amplitude box is located on the Tracking Bar and is only available while you are rubber banding the following predefined curves from the Curve Type options: Simple Break , Saw Tooth Break , Long Break , Simple Tubular Break , Solid Rod Break , and Solid Tubular Break .

Page 290: Drafting

Spline Amplitude = 1 Spline Amplitude = 2

Curve Type

The Curve Type list provides you with the following options for defining curves in a boundary region.

Select Lets you select an existing curve near its endpoint. The system connects this curve to the boundary you are presently creating with a construction line. Another construction line rubberbands while the system waits for you to select the next curve. Select is useful when you are creating a boundary region by using the Spline option. After you create the spline, choose the Select option so that you can pick the spline and continue creating your boundary region. Self intersecting curves (e.g. Simple Tubular Break, Solid Rod Break, Solid Tubular Break, etc.) are not selectable.

Copy Lets you copy an existing curve. The system makes a copy of the selected curve and connects it to the previously defined curve. The copy then rubberbands while waiting for you to specify the copied curve's end point position. Self intersecting curves (e.g. Simple Tubular Break, Solid Rod Break, Solid Tubular Break, etc.) are not selectable.

Create Lets you create a spline. The system rubberbands a line from the end of the previous point or curve while waiting for you to define the next spline point. The spline updates to include each new point as it is defined.

Predefined Break Curves Lets you add a predefined break curve or construction line. The system rubberbands the break curve or construction line while waiting for you to indicate the curve's end point location. After you add the first predefined break curve the system defaults to the construction line option.

Common concepts You create section views by constructing a section line symbol in a parent view. Since the resulting section view is dependent on its section line symbol, a true parent/child relationship exists between the parent and associated section view. Therefore you cannot delete the parent view without getting an Update Failure list warning that:

“Section views of a deleted parent view are also deleted.”

Likewise an associative section line symbol (one created with a dependent section view) cannot be deleted from the parent view. You must delete the section view itself in order to delete the section line symbol.

Section line symbol associativity

Section line segments can either be placed on model geometry or at cursor locations. When you attach a section line segment to a model point, that segment becomes associated with the model point and will move when that point moves. Likewise the section view will update to reflect any changes to the section line symbol or to the model geometry in the parent view. The following figure illustrates a stepped section view in which cut positions have been placed on the two holes in the model. Note that the section view updates after changes to the model are made.

Before Change in Geometry After Change in Geometry

Section Line and Section View Associativity

Section Line Segments

A section line symbol consists cut segments, arrow segments, and bend segments. Multiple cut segments are attached to each other with bend segments.

Page 292: Drafting

Components of a Section Line - Cut, Arrow, and Bend Segments

1. Arrow Segment Arrow segments define the direction of sight for viewing the section. The arrowhead type displayed in the view depends on the symbol standard being used. Arrow segments are always perpendicular to cut segments and if they are not manually placed, are automatically placed according to the (D) Border to Arrow Distance value in the Section Line Preferences dialog box.

2. Bend Segment Bend segments connect cut segments to each other. Bend segments allow you to route multiple cut segments through different features of the part you want sectioned in the view. Bend segments are perpendicular to cut segments and if they are not manually placed, are placed automatically at the midpoint between two cut positions. Bend segments for revolved section views are circular.

3. Cut Segment A portion of a section line that defines a cutting plane. Cut segments are manually placed on the view.

Manual Arrow and Bend Segment positions Bend and arrow segments are considered to be manually placed whenever they are moved during section line creation and editing. Like cut segments, arrow and bend segments can be placed on model features. Any section line segment placed on a model point becomes associated with that point and will update with the model, but those placed at cursor locations do not respond to model edits.

To manually place a section line segment during section view creation:

In the Section View dialog bar, from the Section Line group, click Move Segment , then drag the segment to a different location.

Converting manually placed segments to automaticall y placed To change a manually place arrow or bend segment to an automatically placed one, delete the segment. To do this:

Right-click the section line symbol in the parent view and choose Edit . In the Section Line dialog box, click Delete Segment , then select the segment you want to convert to an automatically placed segment.

NX automatically regenerates a new segment at an automatically placed position.

Note: Because automatic arrow and bend segments are deleted and remade upon drawing update, any annotation that is associated to these arrows and bends become retained when the drawing is updated. It is therefore recommended that manually placed arrows and bends be used whenever annotations are associated with the section line segments.

Required number of section line symbol segments The table below shows the required number of arrow and bend segments for each section line type. If the required number of segments are not user-defined, the software automatically generates them.

Type of Section Line Required Number of Arrow Segments Required Number of Bend Segments

Page 293: Drafting

Simple 2 No bends

Stepped 2 1 bend between each 2 cut segments

Half 1 1 (bend must be user-defined)

Revolved 2 1 bend between each 2 cut segments (except at rotation point).

Hinge Line A Hinge Line is a linear reference used to orient the section view cut position(s) in the parent view. When creating simple, stepped or half section views, the section line cut segments are parallel to the hinge line.

1. Hinge Line

2. Cut Segments

Hinge Line group

Infer Hinge Line

Define Hinge Line

Reverse Direction Infer Hinge Line Hinge lines can be automatically inferred by orienting the section line cut segment in the parent view. This is the default action for section views. Start by selecting a model point in the view. You can then drag the cut segment 360 degrees about that point. The cut segment snaps to 90 degree increments as you drag it. When you click to place the view, the system assumes that the cut segment and hinge line coincide. In this case, the cut segment is associated with the model point you selected. Any subsequent cut segments added to the section line are parallel to the first cut segment.

Define Hinge Line Hinge lines can also be manually defined by selecting model geometry in the parent view. When you click Define Hinge Line , you can use the Inferred Vector list to select two points, a face, an edge or various axes directions to orient the hinge line. The hinge line is associated with the geometry you select and will change its orientation as the model updates. Any cut position likewise updates to remain parallel to the hinge line.

Reverse Direction

Page 294: Drafting

Mirrors the arrow direction about an inferred or associative hinge line.

Associative Hinge Line The Associative Hinge Line option lets you associate the orientation of a section view with the hinge line when you create the section view. You can associate Simple, Stepped, Half, Revolved, or Unfolded section types to a hinge line. This option is not available if the section type is Pictorial Simple/Stepped or Pictorial Half.

Section Line Style/Preferences overview

The NX environment uses a single dialog box with a set of dynamic options to control the style and preferences of the Section Line object. The same dialog box is used to create or modify the visual appearance of a section line, as well as control the preference settings for the options associated with all section lines. The dialog box is called the Section Line Style dialog box if you are creating or modifying a section line. It is called the Section Line Preferences dialog box if you are setting the global preferences for all section lines.

The title of the dialog box, and the options displayed in the dialog box, depend on whether you are setting the display characteristics of new or existing section lines, or setting the display preferences for all section lines.

From this dialog box you can:

Control the label and label location for the section line.

Set the standard for the section line display. Supported standards are ANSI, ISO, ISO 128, JIS and GB and ESKD.

Set the appearance and display characteristics of all components of the section line.

Note: Retained section lines are not selectable from Edit→Style , or from selecting a section line symbol with right-click→Style .

JIS Section Line Display The Japanese Industrial Standard (JIS) Labels automatically generate JIS section line letters. Before you can generate JIS section line letters, you must set-up the appropriate variables in the customer defaults. The following explains the customer default settings:

Note: In general, uppercase letters are used. Do not inadvertently enter zero (0) for the letter O.

1. The rotation letter must be defined in the Customer Defaults dialog as follows:

Drafting→ Section Line Preferences→ Letter → O

Page 311: Drafting

2. The rotation letter must be included in the Allowed Letters entry box on the Customer Defaults dialog as follows:

Drafting → View Label→ General→ Allowed Letters

ABCDEFGHJKLMNOPRSTUVWXYZ

3. The rotation letter must be removed from the Excluded Letters entry box on the Customer Defaults dialog as follows:

Drafting→ View Label→ General → Excluded Letters → IOQ

The excluded letters list takes precedence over the Allowed Letters list and the rotation letter. If a letter is in the excluded letters list, it is not used as a view label or section line letter.

To make a letter list blank, use double quotes in the Excluded Letters text box, like the following line:

Excluded Letters: ""

If the double quotes are not there, the letters IOQ are considered excluded letters by default.

4. Set the Section Line Preferences type for JIS.

For simple section cuts, JIS generates the standard section line labels such as A-A, B-B, etc. For stepped section cuts, JIS generates standard JIS section labels of the form A-B-C-D-E-F-..., as shown in the following figure.

Standard JIS Section Line Label

For a stepped JIS section line with a cut and bend defined at a hole center, a rotation letter (usually letter O), marks this location as shown in the following figure.

Page 312: Drafting

The JIS revolved section line appears as follows.

Note:

Page 313: Drafting

Please note the following items:

Existing pre-v18 JIS section lines are not converted to include the additional JIS letters and appear exactly as they were originally created. They can be updated to the new style by updating the views, or by toggling OFF the Display Label setting in the Section Line Preferences dialog, then toggling it back ON.

The rotation letter is placed at an offset (defined in customer defaults) from the intersection of the bend and cut segments, directed along the vector of the bend segment .

JIS section lines affect Half, Stepped, Revolved and Unfolded section lines. Also, it affects simple sections if you edit them to be stepped. It does not affect pictorial sections.

The rotation letter character cannot be used for another cut segment.

A section line with multiple rotation points may have only one rotation letter. You can define which rotation point gets the rotation letter with the Define Rotation Letter Location option.

If a JIS section line A-B-C exists, the next JIS section line created is named D-E-F-G...

If a JIS section line A-B-C-D-E is edited to remove segment B-C, the line becomes A-B-C-D.

The letters should be sorted from start to finish. If a section line was lettered A-B-C-D and a segment was added between A and B, the section line becomes lettered A-B-C-D-E where E is the next available letter.

If a stepped JIS section line A-B-C-D-E-F is edited to remove cut segment B-C, the line becomes A-B-C-D.

If a JIS section stepped line A-B-C-D is edited to remove a segment B-C, the section line (which is now a simple section line) becomes A-A.

Section line letters are not reusable (with the exception of the rotation letter) on different drawing sheets in the same part file.

Define Rotation Letter Location To define a different section line letter as a rotation letter:

1. With your cursor over a section line, right-click and choose Style .

Annotation Style/Annotation Preferences overview The NX environment uses a single dialog box with a set of dynamic options to control the style of all Drafting and PMI annotation. The same dialog box is used to create or modify the visual appearance of annotation, as well as control the preference settings for the options associated with all annotation types. The dialog box is called the Annotation Style dialog box if you are creating or modifying annotation. It is called the Annotation Preferences dialog box if you are setting the global preferences for all annotation types.

The title of the dialog box, the tabs displayed in the dialog box, and the options displayed on the different tabs of the dialog box, depend on whether you are setting the display characteristics of new or existing annotation, or setting the display preferences for all annotation types.

From this dialog box you can:

Control the color, font, width, orientation, and other properties of textual annotation.

Control the appearance of leader lines, extension lines, and arrows.

Control the format of tables and parts lists.

Control the color, font, width and size of symbols.

Reset tab options or all annotation options to the part standard setting using the Load Defaults or Load All Defaults button.

Page 320: Drafting

The following options are available.

Dimension display type

Description

No Tolerance

Displays the dimension without a tolerance value. All tolerance values are ignored.

Horizontal dimension with no tolerance and nominal size of 8.00 inches

Equal Bilateral Tolerance

Displays the dimension with a bilateral tolerance value, formatted on one line. Only the upper tolerance value is used. The lower value is ignored.

Horizontal dimension with equal bilateral tolerance

Bilateral Tolerance

Displays the dimension with a bilateral tolerance, formatted on two lines. The upper tolerance value is displayed on top, and the lower value is placed on the bottom.

Page 321: Drafting

Horizontal dimension with bilateral tolerance

Unilateral +

Displays the dimension with a unilateral tolerance, formatted on two lines. The upper tolerance displays the given value. The lower tolerance is always zero.

Horizontal dimension with unilateral, positive tolerance

Unilateral –

Displays the dimension with a unilateral tolerance, formatted on two lines. The upper tolerance is always zero. The lower tolerance displays the given value.

Horizontal dimension with unilateral, negative tolerance

+ Limit Two Lines

Creates upper and lower dimension limits by adding the values in the tolerance fields to the nominal dimension. The upper and lower limits are displayed on two lines.

Horizontal dimension displayed as positive and negative limits, on two lines

- Limit Two Lines

Creates upper and lower limits by adding the values in the tolerance fields to the nominal dimension. The upper and lower limits are displayed on two lines, with the upper limit displayed below the lower limit.

Page 322: Drafting

Horizontal dimension displayed as negative and positive limits, on two lines

+ Limit One Line

Creates upper and lower limits by adding the values in the tolerance fields to the nominal dimension. Upper and lower limits are both displayed on one line. The upper limit is displayed to the left of the lower limit.

Horizontal dimension displayed as positive and negative limits, on one line

- Limit One Line

Creates upper and lower limits by adding the values in the tolerance fields to the nominal dimension. The upper and lower limits are both displayed on one line. The upper limit is displayed to the right of the lower limit.

Horizontal dimension displayed as negative and positive limits, on one line

Limits and Fits

Displays the dimensions with limits and fits tolerances. This value is based on the dimension value and is derived from customizable lookup tables which are located in the directory specified by the UGII_GDT_DIR environment variable. Lookup tables for English parts are based on the ANSI B4.1 drafting standard. Look up tables for Metric parts are based on ANSI B4.2, ISO 286, JIS B0401, DIN 7182, ESKD, and GB 4458.5 drafting standards. You can control the limits and fits display using the options on the Dimension tab of the Annotation Preferences dialog box.

Note: A limits and fits tolerance can only be specified for dimensions in parts with English units of measure when the drafting standard for the part is set to ASME.

Hole dimension with limits and fits symbol and tolerance

Basic

Displays dimensions as a value enclosed in a rectangular box. No tolerance values are displayed.

Horizontal basic dimension

Page 323: Drafting

Tip: To create a basic dimension with a multiplier inside the basic dimension box, enter the text control character <#An> (where n is a numeric value) into the appended text field. This multiplier denotes the number of times or places the dimension is used. The following figure illustrates what would happen if you entered <#A2> into the append field

A horizontal Basic dimension with a multiplier inside the basic dimension box

Reference

Displays dimensions as a value inside parentheses. Tolerance values do not display.

A horizontal reference dimension

Diameter Reference

Creates a diameter reference dimension. Both the diameter or radius symbol, and the dimension value, are displayed inside the parentheses. This applies to radius, diameter, and cylindrical dimensions, but only applies when the radius or diameter symbol is before the dimension. Tolerance values are not displayed.

Not To Scale

Displays the dimension with an underscore. The tolerance value is not displayed.

A horizontal dimension that is not to scale

Tolerance Values When displaying the dimension tolerance, NX uses two tolerance values: an upper value and a lower value.

Normally a positive tolerance is the upper tolerance value (for example, .030), and a negative number is the lower tolerance value (for example, -.030). However, you can enter a negative number in the upper tolerance value position, enter a positive number in the lower tolerance value position, enter two positive values, or enter two negative values. For this option, when referring to the upper tolerance value, the number that is in the upper tolerance slot is used, regardless whether it is positive or negative.

Round-off rules for Drafting The Drafting application uses the following standard rules for rounding off digits (within 10 significant digits) when a value is to be rounded to fewer digits than the total number available.

If the numbers after the required precision (number of decimal places) is less than 5, then there is no change in preceding digits (round down). For example, 2.4634 rounded to three decimal places would be 2.463.

Page 324: Drafting

If the numbers after the required precision is greater than 5, the preceding digit is increased by 1 (round up). For example, 4.37652 rounded to three decimal places would be 4.377.

If the number after the required precision is exactly 5, round off to the nearest even number. For example, 8.36500 becomes 8.36 when rounded to two decimal places. 8.35500 also becomes 8.36 when rounded to two decimal places.

Fill/Hatch options overview Use the Fill/Hatch tab on the Annotation Style and Annotation Preferences dialog box to set the default parameters and style for crosshatch and area fill patterns.

From this tab you can:

Select the pattern style for both crosshatch and area fill patterns.

Set the scale and angle values for the area fill pattern.

Set the line distance and angle values for the crosshatch pattern.

Control the color and line width for both crosshatch and area fill patterns.

You can also use the Crosshatch command and Area Fill command to control pattern parameters when creating or editing a specific crosshatch or area fill pattern.

User-defined crosshatch patterns Hatches patterns are contained in crosshatch definition files, sometimes referred to as .chx files, and is a text file which contains the definitions of the hatches. Drafting provides twenty ANSI Y14.2M hatches in two separate crosshatch definition files (xhatch.chx and xhatch2.chx). These files are located in the directory defined by the UGII_UTIL evironment variable. .

Note: It is recommended that you do not edit the system default definition files, xhatch.chx and xhatch2.chx when creating new crosshatch patterns. Instead, create a user-defined .chx file to manage your unique patterns..

Create your own crosshatch patterns You may define your own hatch patterns by creating your own crosshatch definition file. This file must have an extension of .chx and must be located in the current directory or directory pointed to by the UGII_UTIL environment variable.

Warning: Although the File Selection Box permits you to select any directory, the database only supports the UGII_UTIL directory or current directory for the storage of crosshatch definition files. To avoid any problems we highly

Page 357: Drafting

recommend that you store your user-defined crosshatch definition files in the directory pointed to by the UGII_UTIL environment variable.

Hatch Style Is Stored with the Part The definition of a hatch style is stored with the crosshatch entity when you create it on the screen. This allows the system to display and regenerate the hatch. You can also create a hatch that does not exist in any available .chx file by inheriting from an existing hatch entity on the screen.

Note: The drawing containing the hatch may be moved to another system. It is not necessary to have the .chx file on the same system.

CHX File Format The format for the Crosshatch Definition (.CHX) file is as follows:

NAME=name format for line #1 format for line #2 format for line #3 ... ... {ALTANG, m {, n} ... ...} NAME=name ... ... ... NAME=name ... ... ...

to be repeated for each hatch type, where "name" is the name of the hatch type to be displayed in the dialog from the Fill/Hatch option, and {} indicates optional keywords.

The format for an individual line is as follows:

keyword {, param}, keyword {, param}, keyword {, param}, ...

The format for each line is displayed when the hatch pattern style name is used. The pattern style is drawn until exhausted, and is then repeated until the boundary is filled.

Keywords are reserved to define how the pattern style should be displayed.

Keywords Description

! Any text following in the same line is a comment.

> If in character position 1, this is a continuation line.

NAME=name Specifies the name of the hatch style. This is the first keyword to be used in the definition of a single hatch style and must be the first non-comment line in the .chx file.

The NAME keyword must always be followed by an equal sign (=). The equal sign is followed by a string of up to 18 characters for the name of the hatch style. This keyword, including the name, must be on a separate line.

The hatch style name is displayed in the list box for crosshatching.

SOLID This line is a solid line. All other keywords on this line are ignored. This keyword must be on a separate line.

SKIP This line is not drawn. All other keywords on this line are ignored. This keyword must be on a separate line.

DASH, n A dash of length defined by n multiplied by the user-specified crosshatch spacing is drawn. Value n must be specified. For example, if the user-specified crosshatch spacing (in the Preference pull-down) is .25 inch, then DASH, 2 means a dash of .50 inch is drawn.

SPACE, n A space of length defined by n multiplied by the user specified crosshatch spacing exists before the next dash. Value n must be specified. For example, if the user-specified crosshatch spacing (in Preference pull-down) is .25 inch, then SPACE, 2 means a space of .50 inch exists before the next dash is drawn.

OFFSET, n The line is started a length defined by n multiplied by the user-specified crosshatch spacing down the hatch line. Value n must be specified. This is used to "offset" the display of a line, as shown in the following figure.

Page 358: Drafting

Example of OFFSET

ALTANG,m {,n}

Changes the angle of hatch lines to an angle m relative to the user specified angle. Value m must be specified.

For example, if the default crosshatch angle is 45 degrees, then ALTANG, 90 means the angle of the line is drawn at 135 degrees (45+90).

The value n indicates the line spacing relative to the default crosshatch spacing. The value n is optional. If n is not specified, 1.0 is the default.

Using ALTANG with an m value allows you to define hatching in more than one direction. Specifying an n value different from 1.0 allows you to define the second direction hatching with a different line spacing from the first direction line spacing (shown in the following figure).

The ALTANG keyword must be on a separate line.

Example of ALTANG

Note: For all lengths indicated in the keyword meanings, the unit value is equal to the user crosshatch spacing specified and indicated in the dialog from the Fill/Hatch option. This is also referred to as the default crosshatch spacing.

.CHX File Limitations The following general limitations apply to user defined crosshatching:

A maximum of 20 DASH/SPACE keywords can be used to define a single hatch line.

A hatch pattern can have up to 20 hatch definition lines defining it.

A hatch pattern can have up to 4 directions of hatching, with each direction using a different line spacing (spacing between the lines).

The length of a single dash or space in a hatch line cannot exceed 32 times the crosshatch line spacing.

A single crosshatch entity cannot have more than 32,000 line segments.

A crosshatch entity cannot have more than 100 boundaries.

Page 359: Drafting

Example An example of a crosshatch definition file:

NAME=STEEL SOLID SOLID SKIP ! NAME=MARBLE/SLATE/GLASS DASH, 1.0, SPACE, 1.0 SPACE, 1.0, DASH, 1.0 ! NAME=ALUM/MAGN SOLID ALTANG, 90 OFFSET, 0.5, DASH, 1.0, SPACE, 1.0 OFFSET, -0.5, DASH, 1.0, SPACE, 1.0

Fill/Hatch options Note: See Common Annotation Style/Annotation Preferences dialog box options for common options not discussed here.

Option Description

Crosshatch and Area Fill Tolerance

Lets you control how closely NX approximates the crosshatch or area fill boundary along curves, such as splines and conics. The smaller the value, the closer the approximation. However, the smaller the value, the longer it takes NX to construct the crosshatch or area fill pattern.

Tolerance-based approximation of crosshatching and fill boundaries

Note: Crosshatching/fill may be extremely time consuming for large boundaries; especially if you use a small tolerance value.

Automatically Exclude Annotation

When selected, the Automatically Exclude Annotation option in the Crosshatch dialog box and in the Area Fill dialog box is set by default.

Text Island Margin

Sets the margin around excluded text in a crosshatch or area fill pattern. The margin is calculated as a percentage of the text character size.

= percentage of text character size

Note: The margin is a function of text character size, not the scale of the text. The margin will be the same size for a text string whether it is scaled or not.

Area Fill Sets the default pattern for new area fills. NX provides 10 different ANSI Y14.2M area fill patterns.

Scale Controls the scale of the area fill pattern. A value greater than zero, but less than 1, makes the pattern smaller than actual size. A value greater than 1 enlarges the pattern.

Page 360: Drafting

Option Description

Scale = 1.0

Scale = 2.0 Cork/Felt pattern at different scales

Angle Controls the rotation angle of the area fill pattern. The angle is measured counterclockwise from a line parallel to the bottom of the drawing.

Angle = 0°

Angle = 45° Earth pattern at different angles

Crosshatch File Displays the name of the current hatch file. Click Browse to select a crosshatch .chx file.

NX provides twenty ANSI Y14.2M hatch patterns in two separate crosshatch definition files, xhatch.chx and xhatch2.chx. You may also create your own crosshatch patterns in a user-defined .chx file. Additional information.

Crosshatch Pattern list

Lets you select the current crosshatch pattern from a list of patterns contained in the Crosshatch File.

Distance Controls the distance between crosshatching lines. This distance (shown as "D" in the following figure) affects the spacing between crosshatching lines.

Example of crosshatch spacing for Iron/General, Steel and Lead patterns

Note: If manually created crosshatching is associated to a section view and created on the drawing (not in the section view), the display of the hatch spacing does not change when the section view scale is changed. If however, manual crosshatching is associated to a section view and created in the section view, the display of the hatch spacing changes when the section view scale is changed.

Angle Controls the inclination angle of the crosshatching lines. The angle is measured counterclockwise from the positive XC axis (always horizontal in a drawing) to the primary crosshatch lines. If the crosshatch pattern has a secondary crosshatch direction, the lines are always constructed perpendicular to the primary crosshatch lines

Page 361: Drafting

Option Description

– Angle

– Primary crosshatch direction

– Secondary crosshatch direction

Note: If you change the angle of a crosshatch that was automatically generated in a section view, and Preference→View Display→Section View→Assembly Crosshatching is selected for that section view, the angle of the crosshatch reverts to its original value when the section view updates. This is because the Assembly Crosshatching preference affects all section view crosshatching, even when there is no actual assembly (i.e., you are working in a piece part).

Color and Font Lets you specify the color and width of crosshatch lines, or the color of the area fill pattern.

Parts Lists overview Use the options on the Parts Lists tab to set styles for new parts lists and edit the style of existing parts lists.

With the Parts List options you can:

Control the text display in a parts list.

Control the sizing and resizing behavior of the parts list.

Control the behavior and display of locked and manual rows.

Set the auto balloon symbol display for parts lists.

Parts Lists options Note: See Common Annotation Style/Annotation Preferences dialog box options for common options not discussed here.

Parts Lists options

Grow Direction Indicates the direction of growth for the parts list. Provides the following options:

Upwards - causes the parts list to grow in the upward direction on each section (the first piece number is at the bottom).

Downwards - causes the parts list to grow in the downwards direction (the first piece number is at the top).

Show Locked Deleted Rows

Determines how to show rows that are locked, but reference components that have been removed from the assembly or have been manually deleted. The possible values are:

Strike Thru - Display the entire row and it's attached rows with lines through them

Blanked - Don't display the text of the row or it's attached row. Leaves blank rows in their places.

Hidden - Don't display the row or it's attached rows at all.

Ordinary - Display the row ordinarily as if it had not been deleted.

Page 362: Drafting

Lock Parts List Setup

Ensures that parts lists created using the parts list template adhere to the template. By locking the parts list template you can prevent the setup of new parts lists from being different from the template. When the template is locked, setup commands that are not allowed are not available in newly created parts lists.

Create New Rows as Locked

If selected, new rows in the parts list are locked automatically on creation.

Allow Manual Rows

Allows for the manual addition of rows to the parts list. The default is ON.

Symbol Specifies the type of Identification symbol used to call out parts list members (components, solid bodies, curves, and points) on the drawing. The possible values are:

None

Circle

Divided Circle

Triangle Pointed Down

Triangle Pointed Up

Square

Divided Square

Hexagon

Divided Hexagon

Quadrant Circle

Rounded Box

Underline

If set to any of the values besides None, then after an Auto Balloon operation, Identification symbols of that type are created and associated to the members referenced by the parts list. Also, existing balloon symbols update when the parts list updates.

If set to None, then no callout symbols are created when the parts list updates. If symbols already exist, then they are updated.

Note: Note that symbols are only created when one or more views are associated to the parts list. To associate a view to a parts list, use Edit→ Parts List Levels or Tools→Table→Auto Balloon.

Main Symbol Text The text to display in the main callout symbol. This represents the first symbol that gets created on the first occurrence of a parts list. The possible values are:

None - No callout symbol is created for the main callout.

Callout - The callout symbol contains the value that is present in the callout column for the row being called out. This is equivalent to specifying the "custom" option and typing $~C in the Custom Text box.

Part Name - The callout symbol contains the name of the member for this row. This is equivalent to specifying the custom option and entering <W$=@$PART_NAME> in the Custom Text box.

Callout and Quantity - This places the callout value on the first line and the quantity value on the second line. This is intended to be used with the split type of Identification symbols. This is equivalent to specifying the "custom" option and entering <T$~C!$~Q> in the Custom Text box.

Custom - Allows you to manually specify the main symbol text.

Custom Text (for Main Symbol Text)

Lets you enter main symbol text. This option is only available when you select the Custom option from the Main Symbol Text option menu.

Reference Symbol Text

The text to display in the reference callout symbol. This represents the symbols created for the occurrences of the parts list members after the first symbol has been created (i.e. the subsequent callout symbols). The symbol string is in the same format as that for Main Symbol Text. This item has the same

Page 363: Drafting

options as Main Symbol Text.

Custom Text (for Reference Symbol Text)

Lets you enter reference symbol text. This option is only available when you select the Custom option from the Reference Symbol Text list.

Callout Suffix Appends the text specified by the value in the text box adjacent to the reference callout symbol string. This causes reference callouts to have this text appended. This item is not sensitive if Reference Symbol Text is set to Custom.

Initial Callout The initial text string used to represent the first callout in the parts list. If this string ends with a numeric digit (0-9), then the numeric sequence is incremented by the value in the Increment option. If it ends with an alphabetic character (A-Z or a-z), then the alphabetic sequence is incremented by the value in the Increment option.

Increment The amount to increment the callout string between rows. This can be any positive integer value.

Characters to Skip A comma separated list of characters to skip when creating a new callout value. This option is only available if the last character in the Initial Callout box is an alphabetic character.

Automatic Update When selected, causes the parts list to automatically update whenever a change occurs to a referenced object in the model.

Sort on Update When selected, causes the parts list to automatically sort during update based on the sort criteria defined for each of the columns using parts list column properties

Highlight Manual Text

When selected, then manual text is enclosed in manual text brackets.

Manual Text color box – Indicates the color of the highlight brackets. This item is available only if Highlight Manual Text is selected.

Section overview Sections are drafting table objects that comprise the individual pieces of a table (tabular note or parts list). Tables are comprised of one or more sections that each contain an exclusive set of rows in the table. This breaks the table up into small pieces that can easily fit onto drawing sheets.

Table with Two Sections Note that the header row appears in both sections. Sections are assigned a style that allows them to grow to a maximum user-defined height. When new rows are added to the table such that the section would exceed the maximum height, a new section is created and placed relative to the previous section according to a style setting on the section object.

Section Preference options Note: See Common Annotation Style/Annotation Preferences dialog box options for common options not discussed here.

Section options

Location of Header

Determines if the header rows display at the top or bottom of the section. Options are as follows:

Above - Displays at the top of the section.

Below - Displays at the bottom of the section.

None - The header does not display.

Maximum Height

The maximum height in part units of each section before overflowing to the next section. Note that each section contains at least one row (attached rows can separate from their parent by overflowing to the next section). This value must be greater than or equal to zero. If set to zero, no new sections are created after the edited section.

Overflow Determines where to expand when overflowing rows to new tabular note sections. Options are as follows:

Left - Expands to the left of the current section. This expansion continues as needed until the left border

Page 364: Drafting

of the drawing is reached. When that happens, the section that follows is created on the next sheet at the position of the first section in the table.

Right - Expands to the right of the current section. This expansion continues as needed until the right border of the drawing is reached. When that happens, the section that follows is created on the next sheet at the position of the first section in the table.

Next Sheet - Expands to the next sheet in the sequence (a section on drawing SH1 expands to SH2, then SH3, and so on). The sequence increments either a number or a letter, depending on the last character of the drawing name containing the initial section. The position of the new section is the same X, Y position as that of the first section on the previous drawing. If the next sheet in the sequence does not exist it is created using the same drawing styles of the drawing of the previous section.

Spacing When Overflow is set to Left or Right, this specifies the distance in part units between the previous section and the new section. Otherwise, this item is unavailable.

Alignment Position

Specifies how the tabular note section aligns relative to the cursor during placement and relative to other sections when origins are aligned. The Alignment ptions are:

Top Left - Alignment position is at the upper left corner of the section

Top Right - Alignment position is at the upper right corner of the section

Bottom Left - Alignment position is at the lower left corner of the section

Bottom Right - Alignment position is at the lower right corner of the section

Double Border

Specifies if the border around the tabular note is drawn as two lines.

Border Offset

Determines the width between the double borders. This option is available only when Double Border is ON.

Apply To Determines how the changes made to the section styles are applied. Options are as follows:

This Section - Changes only apply to new sections created after setting the styles.

All Sections - Changes apply to all existing sections in the tabular note and new sections.

Annotation Style/Annotation Preferences — Columns tab The Columns tab is available when you right-click and choose Style on one or more columns of a parts list or tabular note.

Note: See Common Annotation Style/Annotation Preferences dialog box options for common options not discussed here.

Columns options

Column Type Lets you set the column to be one of the following types:

Callout — the contents of the cell is a piece number that generates automatically. By default piece numbers start at a user-defined alphanumeric value and increment by a user-defined value throughout the rows of the parts list. These user-defined values are defined in the Parts List property page.

If a callout type column references the CALLOUT attribute (by specifying CALLOUT in the Attribute Name box), then it displays the value of the CALLOUT attribute on the member, if not, the value of the CALLOUT attribute on the member is set to the value in this text box when the parts list updates.

Note that when working in the Teamcenter environment, in order to synchronize the piece numbers with database sequence numbers, the Attribute Name field for callout columns should be set to "CALLOUT". This causes the CALLOUT attribute to be read for the value of the cell in the callout column, and prevents the parts list from writing the CALLOUT attribute.

General — a general purpose column. You usually use this option in conjunction with the Attribute Name option to display the value of an attribute on the member. You can use this option to:

Generate a string from the value of an attribute on the components.

Generate a reference to an interpart expression in the component part.

Create a column of manual entries.

Quantity — counts the number of occurrences for each component that correspond to each row. Table cell styles provides the ability to use a formula in conjunction with the computed value to modify

Page 365: Drafting

the value that is displayed. You can use the Evaluate Cell as a Formula option to increase the quantity by a specified fixed number or by a percentage.

Attribute Name

Specifies the attribute name to evaluate for the automatic text. This is a combo box that allows you to enter a value for an attribute or choose one of the options. The list of options includes the software defined attributes and the names of all attributes on all components that are descendents of the displayed part. This item is only available when the column type is General and if you have not manually edited the default text.

Default Text Lets you edit the default text of the cells in the column. You can use this instead of specifying an attribute name to provide more control over the actual text that displays in the cells. If the resulting edited cell text comprises more than a single attribute type parametric text reference, then the Attribute Name field is disabled.

Setting this option to blank results in an empty column in which manual entries can be entered into the cells.

When you use this function in conjunction with Apply to , it can only modify new cells added to the column (as a result of adding new rows) or to all cells in the column.

Some of the applications of this function include providing the ability to enter manual text into a column, specify multiple attribute references in one column, and referencing expressions from cells in the column.

Apply To Indicates the scope of what cells update when using Default Text and the Cells and Fit Methods tab options. The following options are available:

Cells in New Rows — only cells in newly created rows have their styles updated.

All Cells in Column — all cells in the column have their cell styles updated to the new values.

Key Field Indicates if items in this column define uniqueness for a given row. If this item is set, then two components whose named attribute evaluates to the same value are regarded as equal and combined into a single row, thereby causing the quantity to increment for that row. If this is set on multiple columns, then all columns must be unique in order to exhibit this behavior. This item is only available if the column type is General or Callout.

Note: Note: If the callout column has the Key Field item selected, then each parts list member has its own row and item number, thereby setting the quantity value to 1.

Protect Column Cells

Protects the contents of all the cells in a column from being manually changed.

Nested Assemblies

If checked, this column supports nested assemblies. When nested assemblies are enabled for a quantity column, the column only reports the quantity for components that are descendents of the parent component. See the Select Parent Component item below.

This item is only available if the column type is quantity.

Select Parent Component

Allows selection of a component to set the parent component for this column. The parent component represents the component for which quantities of cells in this column are computed. Quantities in a cell under this column are incremented only if the component is a descendent of this parent component. If the component represented by the cell is the same as the parent component, then "X" displays in the cell.

This item is only sensitive if Nested Assemblies is checked.

Cells overview The Cells tab provides options for formatting the content of cells and the display of cell borders (color, font, and width) for tabular notes and parts lists.

From the Cell tab you can:

Control the format, alignment, suffix and prefix of the annotation in the cell.

Apply formulas which control the content of a cell.

Insert a URL link for a cell.

Control edit features for cells.

You can only set cell borders in edit mode.

Cells options

Page 366: Drafting

Note: Default settings for cell preferences are controlled by internal settings during parts lists creation. Cell settings are honored when editing a cell or when loading defaults.

Note: See Common Annotation Style/Annotation Preferences dialog box options for common options not discussed here.

Cells options

Format Provides the following options:

Text - Displays literal text. For example, "This is a cell string". For this format type, Decimal Places is unavailable.

Number - Displays a double precision floating point number. For example: 3.141592653589. .

Scientific - Displays numbers in scientific notation format, using "e-," or "e+" exponent codes. Where "e-" indicates a negative exponent and "e+" indicates a positive exponent.

Currency - A floating point number with a dollar sign ($) displayed on the left. For example: $3.14. .

Percent - A double precision floating point number multiplied by 100.0 with a percent character (%) displayed on the right. For example: 314%.

Degrees/Minutes/Seconds - A double precision floating point number represented as an integral number of degrees, minutes and seconds. If the setting is zero places, only degrees displays; if the setting is one place, degrees and minutes displays; if the setting is two places, degrees, minutes and seconds displays; if the setting is set to more than two places, degrees, minutes and seconds displays and the number of places minus 2 is displayed for the number of decimal places for the seconds field.

Fraction - A fraction. When this option is chosen, the Type option menu appears. The Decimal Places option determines the number of digits in the denominator (maximum of 4).

Hidden - Displays an empty cell.

Date - Displays the value as a date. See the Type option.

Time — Displays the value as a time. See the Type option.

Decimal Places

Lets you set the number of digits displayed to the right of the decimal point for all Format types except Text, Hidden, Date, and Time.

Text Alignment

Provides nine text alignment position options.

Full Size - For example:

Page 367: Drafting

Date options

dd-mm-yy - Displays the value as a date in the form dd-mm-yy. This is the integer cell value representing the number of days since December 30, 1899. Note that if that date extends beyond December 31, 1999, it is represented as a 4 digit year string.

mm-yy - Displays the value as a date in the form mm-yy.

mm-dd-yy - Displays the value as a date in the form mm-dd-yy.

yyyy-mm-dd - Displays the value as a date in the form yyyy-mm-dd.

dd.mm.yy - Displays the value as a date in the form dd.mm.yy.

Time options

hh:mm - Displays the value as a time in the form hh:mm. The time is computed using the fractional part of the real valued cell contents where 0.0 equals 0 t and 1.0 equals 1 day (the relationship is linear). The value is rounded to the nearest minute.

hh:mm:ss - Displays the value as a time in the form hh:mm:ss. The value is rounded to the nearest second.

Prefix Lets you specify manual text that always appears before the main text of the cell.

Suffix Lets you specify manual text that always appears after the main text of the cell. Also provides a list of default optons: IN, FT, YD, MM, CM, M, SQ IN, SQ FT, SQ YD, SQ MM, SQ CM, SQ M, OZ, GAL, L, ML, LB, KG, REF, AR, A/R, and EA.

Display Numeric Zero

Controls the display of a null (zero) value. Possible values are:

Zero - Displays the value as a zero. For all Format types that accept a Decimal Places input, the zero value is displayed with an equivalent number of trailing zeros as defined in the Decimal Places box. For example, if the decimal places box has 4, then 45.6 displays as 45.6000.

Dash (-) - Displays the value as a dash ("-") character.

Empty - Displays nothing for the value.

Evaluate Cell as Formula

Causes the contents of the cell to be evaluated as a formula using the rules required for the expression subsystem. This option is useful for incrementing quantity values by a fixed amount or by a percentage.

Increment Value - Specifies a value by which to increment the cell value. If Increment is a Percentage is off, then the value is incremented by this value. Otherwise, the value is incremented by this as a percentage. This item is only available if Evaluate Cell As Formula is enabled and if the cell text contains only a simple automatic text reference.

Increment is a Percentage - Indicates whether the value in Increment Value is interpreted as a percentage. If checked, the value is interpreted as a percentage. This option is available when the Increment Value option is available.

URL Specifies the URL for a web page that displays when you right-click and choose Goto Cell URL. This behavior only exists if this field contains text.

Border (Only in Edit)

These options allow you to set the color/font/width settings for cell border lines. When one of the items is pushed in, the color/font/width settings can be set for that set of lines. You can set the following border options:

All

Fit Methods overview Fit Methods lets you have a prioritized list of methods that execute whenever the text does not fit within a cell in a table. The options on the Fit Methods tab indicate which fit methods to use for the cell, and their order of precedence. Selected fit methods are those that are in use, and the order in the list indicates the order in which they are executed. Each fit method is executed, in their given order, until a fit method succeeds. If all fit methods fail, then the cell is filled with "#" characters.

The order of the fit methods can be changed by choosing one from the list and clicking the up or down arrow to move the item.

Fit Methods options Note: See Common Annotation Style/Annotation Preferences dialog box options for common options not discussed here.

Fit Methods options

Wrap Wraps the text to the next line. This method can fail if the row height is too small to accommodate the new text height. This is often followed by the Auto Size Row fit method.

Auto Size Row

The row height is automatically enlarged to include the contents of the cell. This method only fails if the text is too wide for the cell.

Note: Auto Size Row can resize a row if it is set and it can override the row height setting.

Auto Size Text

The width of the text is automatically adjusted so that the text fits within the cell. This method fails if the sizing causes the aspect ratio to be less than 0.2.

Overwrite Border

Overwrites the text into the cell immediately to the left or right of the cell being updated, depending on the justification of the text in the cell. Left justified text will overwrite toward the right; right justified text will overwrite toward the left. This methods fails if text exists in the adjacent cell being overwritten.

Auto Size Column

The column width is automatically enlarged to include the contents of the cell. This method only fails if the text is too high for the cell.

Abbreviate The text in the cell is abbreviated by removing all vowels in the text string except for one residing in the first position of the string. This method fails if the resulting string still does not fit into the cell.

Remove Spaces

The space characters are removed from the cell text. This method fails if the resulting string still does not fit into the cell.

Truncate Truncates the cell text.

Stacking overview Stacking options control settings for Drafting and PMI annotations that are organized in a stack. These settings include placement and spacing factor options that control the display of objects in a stack with respect to each other.

What is a stack? A stack is a set of Drafting or PMI annotation that maintain a positional relationship with each other. All Drafting annotation and PMI symbols can be stacked except for the following:

Checked GD&T (in other words, the functions in PMI→Geometric Tolerancing )

Chain dimensions (horizontal and vertical)

Baseline dimensions (horizontal and vertical)

Ordinate dimensions

Page 369: Drafting

Drafting tabular notes

Drafting utility symbols

Drafting crosshatch symbols

Stacking options Note: See Common Annotation Style/Annotation Preferences dialog box options for common options not discussed here.

Placement

Above/Below Alignment

Lets you specify one of the following vertical alignment options for an object within a stack:

Left

Center

Right

Left/Right Alignment

Lets you specify one of the following horizontal alignment options for an object within a stack:

Top

Middle

Bottom

Spacing Factor

Above or Below Specifies the space buffer above or below the annotation within a stack, as a factor of a multiple of the character size.

Left or Right Specifies the space buffer to the left to or right of the annotation within a stack, as a factor of a multiple of the character size.

Inherit Associated Objects

Available only on the Annotation Preferences dialog box.

Enables annotation added to a stack to automatically inherit the associated objects of the stack.

Note: Note that only PMI objects can have associated objects.

Autospace

When selected, stacking uses a space setting of zero for feature control frame symbols and datum feature symbols in a stack. This option is on by default.

Autospace is selected

Autospace is not selected

Annotation placement and alignment

Annotation can be placed using precise tools like the Origin Tool, or by using quick gesture techniques which are available using a combination of shortcut menus and the mouse buttons.

Dimension snapping

When placing dimensions on a drawing, NX will automatically snap the dimension to the center of the dimension line when the text is positioned near the center.

Page 370: Drafting

Tip: To disable snapping, press the Alt key while positioning the dimension.

Automatic alignment and helper lines

When placing annotations or dimensions, NX displays helper lines and associativity indicators to help you dynamically align and associate the annotation to existing text while locating it. You can preselect the aligning annotation by passing the cursor over it while placing the new annotation.

The association exists until the annotation is deleted or it is repositioned outside the bounds of the associated text.

Page 371: Drafting

Tip: To temporarily disable helper lines while placing annotation, press and hold the Alt key on Windows

platforms, press and hold the Ctrl+Alt keys on non-Window platforms.

To completely disable helper lines while repositioning existing annotation, clear the Dynamic Alignment option on the Preview tab of the Preferences →Drafting dialog box.

Press and hold Ctrl to force an annotation's leader stub to remain on one side (left or right) while repositioning it.

Perpendicular annotation indicator

When positioning annotation with a single leader line, and you are within a small tolerance of being perpendicular to the selected object, NX snaps the leader to a perpendicular position and displays a perpendicularity indicator in the center of the leader line.

The leader perpendicularity is with respect to the object's normal in the plane of the annotation. If there is no normal, for example using the screen position as the positioning plane, then the leader snapping position is limited to 0, 90, 180, and 270 degree positions.

Tip: Use the Alt key to disable snapping.

Annotation stacking NX lets you automatically position and associate leaderless annotation to other annotation in a stacked arrangement. Placement and spacing parameters for the stacking arrangement are controlled by the options on the Stacking tab of the Annotation Preferences dialog box.

Page 372: Drafting

Associating annotation to extension lines NX supports the ability to associate annotation leader lines to extension lines for datum feature symbols, feature control frames, datum targets, notes, ID symbols, and weld symbols. When the leader terminator is close to the arrowhead of the dimension line, the terminator aligns itself with the dimension line:

Infer Associated View overview

While placing or repositioning leaderless symbols or notes, you can automatically associate the symbol or note to a drafting view by dragging the annotation near a view until the view's border highlights and the associativity indicator appears.

Page 373: Drafting

= Annotation to be placed Annotation associativity indicator

Once you associate an annotation to a view, the annotation moves when the view moves. The functionality is available while you drag annotations in either the create or edit mode, and the Auto Alignment option in the Origin group of the dialog box for the annotation is set to Associative .

Tip: You can disable the automatic associativity mode by holding the Alt key while dragging the annotation. This causes the associativity indicator to disappear and the annotation becomes associated to the sheet no matter where it is placed.

Origin Tool overview

The Origin Tool uses more precise positioning methods for Drafting annotation. The options in the Origin Tool command let you position an annotation or dimension relative to geometry, another annotation or dimension, or a view. A particular use case of the Origin Tool is to align the arrows of a linear dimension with the arrows of a parallel linear dimension.

When you associate annotation with a related item and the location of that item changes, the annotation automatically relocates to maintain the relative position.

Suppress Drafting Object overview

The Suppress Drafting Object command lets you control the display of one or more of the following drafting objects:

Dimensions

Drafting aids

Checked Geometric Dimension and Tolerancing (GD&T) objects

Tabulated notes

The value of a number type expression that you assign controls the visibility of each drafting object. If the expression has a value of zero, the drafting object becomes invisible. If the expression has a nonzero value, the drafting object displays.

You can control the display of multiple objects by assigning the same control expression to all of them, or you can assign one control expression per object.

Caution: Replacing the existing expression of an object can break associativity.

To conditionally suppress drafting objects you must already have a control expression you can use, and the expression must be of the type Number . In the Drafting application, Tools→ Expression is normally unavailable. You can either use this command from another application, such as Modeling, or you can make the option available in Drafting by setting the Allow Expressions option in the Customer Defaults dialog box, on the Drafting →General→Drawing tab

Obtain information on conditional objects Use the Information command to obtain data on conditional objects as follows:

Dimension overview

NX supports the creation of ANSI, ASME, ISO and JIS standard dimension types, including Baseline, Chain, and Ordinate dimensions. Dimension options let you create and edit various dimension types as well as set local preferences that control the display of the dimension type.

NX uses an intelligent inference algorithm to anticipate and create dimensions based on the objects you select. You can also choose to create specific dimension types using the Dimension toolbar, or from the Insert→Dimension menu.

Automatic Annotation NX provides the capability to automatically generate dimension annotation using the feature parameters and Geometric Dimension and Tolerancing (GD&T) features of a model. For additional information, see the Feature Parameter and GDT Parameter topics in this Help guide. If your model contains Product and Manufacturing Information (PMI) features, you can inherit and place PMI annotation and dimensions directly from the model onto your drawing using the Inherit PMI options in the View Style dialog box.

Dimension dialog bar overview The Dimensions dialog bar contains options for controlling the appearance and content of dimension annotations.

The Dimension dialog bar appears when you create either a 2D dimension in the Drafting application, or a 3D PMI dimension in other applications, such as Modeling.

The options that appear on the dialog bar depend on the type of dimension you create.

Dimension to Faces overview

The Drafting application supports dimensions that are associative to faces. If you dimension to the faces of a block, blend the edges, and update the model, the dimensions do not go into a retained state because the dimensions are associated to the faces and not to the edges.

Dimension Associated to Faces Update After Blend - Not Retained Face Selection Restrictions There are two restrictions for face selections:

The 3D distance between the two selected objects must be measurable. Note that the 3D distance between two non-parallel planar faces is not measurable. Only one object needs to be a face. You can dimension between a face and a solid edge, or between a face and a point.

The 2D distance between the projections on the WCS X-Y plane of the selected two objects has to be measurable. Thus, if the projections of two planar faces are not vertical lines, a horizontal dimension cannot be created for them since the horizontal distance between two non-vertical lines is not measurable.

Retain Behavior Restrictions on face selections are enforced during pre-selections. However, if the model changes after dimensions are created and the requirements of face orientations are no longer satisfied, the dimensions become retained. For example, if a model changes and the planar faces are no longer perpendicular to the dimension plane, the dimension associative to the planar face goes into a retained state.

Page 414: Drafting

Create a dimension to faces 1. Select the first face. Use QuickPick to differentiate edge selection from face selection.

2. Select the second face.

3. Drag the dimension to the desired location.

4. Click to place the dimension.

Page 415: Drafting

Supported dimension types and objects

Dimension to faces supports certain objects and dimension types.

Valid views

All views are supported except faceted representation views.

For extracted edge views, you must select Drafting → Preferences → Display and Emphasize in order to select faces for dimensioning.

Linear and Angular dimensions

Linear types - Horizontal, Vertical, Perpendicular, Parallel, Baseline and Chain

Angular types - Angular and Chamfer

Projection of faces in view must form valid lines for the dimension type. For example, a parallel dimension only dimensions between cylindrical faces.

Radial dimensions

Types - Radius, Diameter, Hole, Radius to center, Folded radius, Arc-length, Concentric Circle

Only cylindrical faces projected to arcs are valid.

Cylindrical dimensions

Only cylindrical faces are valid.

If the cylindrical face is not projected to an arc (or it is not perpendicular to a dimension plane), the two silhouette lines of the cylindrical face must be visible in order to be a valid face for dimensioning.

Cylindrical face with only one silhouette line visible Ordinate dimensions

Not supported

Dimension to extension lines overview

When creating Inferred, Horizontal, Vertical, Parallel, Perpendicular, or Cylindrical dimensions, you can select extension lines.

NX uses the extension line closest to the selection position. If there are no extension lines (either because they were turned off or they were not drawn based on the position of the dimension), the dimension is not selectable.

When selecting an extension line, the dimension created is associated to the underlying geometry of the extension line, not the dimension extension line itself.

Perpendicular dimensions When dimensioning to extension lines, NX uses the extension line closest to the selection position. The exception to this rule is perpendicular dimensions. You can only select another perpendicular dimension for the first associativity. NX always uses the first associativity of the selected perpendicular dimension.

If you select a line that is not horizontal or vertical, NX creates either a horizontal, vertical, or parallel dimension depending on the location of the cursor.

Arcs and Circles If you select an arc, a radius dimension is created automatically.

If you select a circle a diameter dimension is created.

Point/Arc/Circle/Ellipse Combinations

If you select any combination of two objects that include points, arcs, circles, or ellipses, NX automatically creates a horizontal, vertical, or parallel dimension, based on the location of the cursor.

Line and Point/Arc/Circle/Ellipse

If you select a line and a point, arc, circle, or ellipse, NX automatically creates a perpendicular dimension. You create the dimension by first selecting a line and then selecting the endpoint on the selected object.

Line and Line To obtain an angular dimension, select non-parallel lines with snap point options turned off.

Dimension non-intersecting lines Lines need not actually intersect to be dimensioned. If two skewed lines appear to intersect when viewed down the ZC axis, the system dimensions the apparent angle (See the following figure).

If two lines intersect but do not lie in the XC-YC plane or a plane parallel to the XC-YC plane, the angle dimensioned is not the true angle.

Tip: NX always projects the lines onto the XC-YC plane to create the dimension.

To dimension the true angle between two intersecting lines, the lines must be parallel to the XC-YC plane.

Cylindrical dimension overview

Use Cylindrical dimension to create a dimension that is the linear distance between two objects or point positions.

To select a point, enable the desired point type on the Snap Point portion of the Selection bar.

Example of a cylindrical dimension

Note: The diameter symbol is automatically appended to the dimension.

Cylindrical dimension can be used to dimension (physically on the drawing) the entire diameter or just half the diameter. The system uses the type of object selected and the order of selection to determine whether the dimension represents the true diameter or the radius.

Page 439: Drafting

If the system determines you are dimensioning the true diameter, the actual physical distance is displayed in the dimension. If the system determines you are dimensioning the radius, then the dimension is displayed with twice the actual physical distance displayed as the dimension value.

Note: The position of the diameter symbol relative to the dimension text is controlled through Preferences →Annotation →Radial .

Note: Cylindrical faces in section views cannot be selected for dimensioning because these faces have no visible silhouettes, which is a requirement for the cylindrical dimension.

Select two points to create a cylindrical dimension for a cone Cylindrical dimensions are useful when dimensioning the profile view of a cone. This should be done by selecting two points. A cylindrical dimension created by selecting two points calculates the minimum distance between those points (similar to parallel dimensioning).

1. Open an existing drawing and start the Drafting application.

2. Choose Insert→Dimensions →Cylindrical .

3. Select point P1.

4. Select point P2.

5. Click to place the dimension.

Cylindrical dimensioning for a cone If the first object selected is a line or centerline, the cylindrical dimension created is always perpendicular to it.

The following figures illustrate what would happen if you created the previous dimension by selecting lines instead of points.

Page 441: Drafting

Example of Incorrect Cylindrical Dimensioning for a Cone

Example of Incorrect Cylindrical Dimensioning For a Cone

Note: The method of selection affects the accuracy of the cylindrical dimension. The previous three figures all yield different values because of the different methods of selection.

Create a cylindrical dimension on a centerline When creating a Cylindrical dimension, if you select a centerline drafting object as your first selection, the system will calculate the cylindrical dimension to be twice the actual distance between the selected centerline and the second line (or point position) selected.

This is illustrated in the following figure, where the value of the cylindrical dimension is twice that of the perpendicular dimension.

Page 442: Drafting

Cylindrical dimension created on a centerline If however, you select the line first, and then the centerline, the resulting cylindrical dimension value is not doubled. Instead, it shows the actual distance value between the line and the centerline.

To create the cylindrical dimension as illustrated in the figure, follow the steps below.

Chamfer overview

The Chamfer command automatically creates a chamfer dimension for 45 degree angled chamfers.

Note: For chamfers other than 45 degrees, you must use other dimension commands to dimension the chamfer.

When you select the chamfer edge, NX usually infers the second object and checks for a 45 degree angle. Under this condition you are not required to make a second selection. However, if the system does not locate a nearby adjacent edge at 45 degrees, you must make a second selection.

For linear chamfer dimensions, the dimension line is initially parallel to the second associative object you select.

Thickness overview

You can create a Thickness dimension between two curves (including splines). The thickness dimension measures the distance between a point on the first curve and the intersection point on the second curve. It measures in the normal direction from the point specified on the first curve.

Page 448: Drafting

Object selection (point on curve used for dimension)

Object selection

If the two curves are arc-like objects (arc, splines shaped like arcs, cylindrical faces, or circular centerlines), NX creates a concentric circle dimension, which measures the difference in radii between two concentric arcs. It then computes the numerical difference between the two radii.

Concentric circle dimension

Caution: Non-concentric curves, while selectable, are not supported by the thickness command and erroneous results will be displayed. Use a different dimension command if you need a dimension between two non-concentric curves.

Ordinate Dimension overview An ordinate dimension consists of text and an extension line which can be straight or have a dogleg. An ordinate dimension describes the distance from a common point called an ordinate origin to a position on an object along an ordinate baseline.

The ordinate origin has two axes or baselines that are perpendicular to each other. You can optionally specify the direction of the first ordinate baseline using vector methods. The second baseline is automatically created perpendicular to the first baseline. If not specified, the default direction is to the drawings horizontal and vertical directions.

2. Ordinate Set Name

3. Ordinate Margins

Page 461: Drafting

Ordinate Dimension Set

6. Ordinate Dimension with dogleg extension

NX automatically assigns an ordinate set name. Optionally, you can choose not to display an ordinate name. You can also display a user-defined symbol at the ordinate origin.

The ordinate dimension aligns to margins which are offset from the baselines. You can optionally define margins. If you do not define margins, NX automatically infers margins when you place the first dimension at orthogonal positions.

The collection of ordinate origin, ordinate set name, and margins forms an ordinate set. You must have a ordinate set before you can create or edit ordinate dimensions. An ordinate dimension set consists of ordinate dimensions and the ordinate set.

Note: Please note the following items:

Ordinate dimension sets should be created in a single view. Creating an ordinate dimension set where the ordinate origin is in one view and the margins and dimensions are placed in another view can lead to undesirable results (for example, ordinate dimensions associated to multiple views do not move/copy or export).

If you create an ordinate dimension set in an expanded view of a member view, you must also perform any edits in the expanded member view.

Where do I find it?

Application Drafting

Toolbar Dimension→Ordinate

Menu Insert→ Dimension→ Ordinate

Ordinate Origin All ordinate dimensions are measured from a common point called the ordinate origin. Unless you specify a direction for the baseline, the vertical dimensions are measured from a line parallel to the bottom of the drawing sheet. The horizontal dimensions are measured from a line parallel to the side of the drawing sheet (See the following figure). When you specify a direction for the baseline, dimensions are measured from the ordinate origin at a distance perpendicular to the baselines.

The Ordinate Origin with Both Horizontal and Vertic al Ordinate Dimensions

— Ordinate Origin

— Vertical Ordinate Dimension with Horizontal Extension Line

You can create an ordinate origin at any of the following symbols:

Center Mark symbols

2D and 3D Centerlines

Bolt Circles (control points)

Offset center points

Intersection symbols

Snap points Snap point options are available on the Selection bar when you define a point for the ordinate origin. To specify a point outside the view or offset from a point on the view, use the Point Constructor .

Ordinate Origin associativity The ordinate origin is associated to part geometry. If the geometry that is associated to the ordinate origin moves, the ordinate origin also moves. For example, if an arc center is specified as an ordinate origin, and later the arc is moved, the ordinate origin moves with the arc and all dimensions associated with that ordinate origin are updated.

Note: Ordinate origins are NOT deleted when the associated part geometry is deleted. They revert to a retained state regardless of how the Retain Annotations option is set.

You can reassociate an ordinate origin at any time by right-clicking the ordinate set name or origin symbol and choosing Edit Associativity . When you select a different point, the origin moves to that point and all dimensions in the ordinate dimension set update to reflect the change.

Note: Ordinate origins should not be confused with datum planes or GD&T datum flags

Positive Direction When you create an ordinate origin, NX automatically divides the view into four quadrants oriented along the baseline directions and centered about the ordinate origin.

Page 463: Drafting

The Positive Direction list on the Ordinate tab of the Annotation Preferences dialog box specifies the positive quadrant. By default all four quadrants are set to positive (All ).

All User-Defined If only one quadrant is to be positive, select User-Defined from the Positive Direction list.

When you select User-Defined , the quadrant symbol appears at the ordinate origin.

The arrows indicate the positive direction. To reverse a positive direction, double-click an arrowhead.

Where do I find it? Preferences →Annotation →Ordinate →Positive Direction .

Dimension Style →Ordinate →Positive Direction .

Baselines Ordinate dimensions use baselines and the ordinate origin to determine the direction of measurement for an object's dimension value. A dimensioned object is measured from the ordinate origin at a direction perpendicular to the baseline.

Page 464: Drafting

— Horizontal Ordinate Dimension Measured from Vertical Baseline

— Vertical Ordinate Dimension Measured from Horizontal Baseline

Tip: To redefine a baseline, right-click it and choose Baseline Direction .

Active and Inactive Baselines The system creates dimensions perpendicular to active baselines. If you have two active baselines, then two ordinate dimensions are created (typically horizontal and vertical dimensions). To create only horizontal dimensions, set the horizontal baseline inactive.

Where do I find it? Choose Insert→Dimension →Ordinate . NX creates baselines when you specify an ordinate origin.

Ordinate Margins NX aligns ordinate dimensions to margins. Defining margins is an optional step. If you do not define margins, NX infers margins around the first ordinate dimension placed. Margins that you define are visible. System inferred margins are not.

Page 465: Drafting

Active Margins

Inactive Margins

A solid line indicates an active margin. Dotted lines indicate inactive margins. Ordinate dimensions snap to the position of active margins.

You may have multiple horizontal and vertical margins in an ordinate set. The limit for vertical and horizontal margins per ordinate set is 32. If you select two collinear margins, they count as one margin. If you create more than one vertical margin (or more than one horizontal margin) the last one created becomes the active margin.

NX uses the active margin for placement of the next dimension. You may make another margin the active margin by double-clicking it or by right-clicking it and choosing Set Active . Also you may redefine a margin offset by right-clicking it and choosing Move .

The dimension is always placed on the side of the margin line furthest from the view's center.

You may create these margins by using the Margin method options or the Snap Point options.

Note: Ordinate dimensions are associative to the margins on which they are placed. If you move a margin, the dimension(s) also move with it. If you delete a margin, the system infers a margin for the dimensions.

Where Do I Find it?

On the Ordinate Dimension dialog bar, click Define Margins .

Margin Origin You define margins by specifying a point as the margin origin. When Define Margins is on, the margin origin displays as a filled circle.

When margin origins are displayed:

Margins defined by a margin origin highlight as you pass your cursor over the margin origin.

This aids you in identifying which margins were defined by a particular margin origin since you can have multiple margin origins in an ordinate set.

The visible margin origin also provides a location where you can access Redefine and Delete shortcut options.

When you move a margin, the Offset is calculated from the location of the margin origin.

Dogleg Extension Lines Extension lines connect the dimension to the object being dimensioned. Extension lines are either straight or have a dogleg (see the following figure).

— Extension Line

Merge Ordinate Sets Move Dimensions to Another Set

Why Move the Ordinate Origin? One reason for moving the ordinate origin is to keep it associated to a position on the part. If this is not done, and the position on the part is deleted (due to a model edit, etc.) all the dimensions associated to that ordinate origin go retained. The following figure shows an ordinate origin (which was originally associated to the arc) moved to an intersection point. This is done prior to removing the existing arc. When the arc is removed all dimensions remain intact.

Maintaining Ordinate Origin Associativity

— Ordinate Origin Associated to Arc Center

— Ordinate Origin Associated to Intersection Point, Prior to the Removal of the Arc

— This Arc Is to Be Removed

Where do I find it?

To edit an active ordinate set, click Dimension Style from the Ordinate Dimension dialog bar. You can also use shortcut menu options on ordinate set objects.

To edit an inactive set, right-click and choose Edit on the ordinate set name. Then use style or right-click options.

Ordinate Dimensions Associativity You can select dimension extension lines when creating ordinate dimensions. When you select dimension extension lines, the ordinate dimensions are not associated to the selected dimension, but rather to the geometry referenced by the selected dimension. If the density of geometry is high or the association is difficult to select, it can be easier to select a dimension that has already established associativity to the geometry of interest such as a linear dimension (horizontal, vertical, parallel, perpendicular and cylindrical).

Page 468: Drafting

When the dimension is selected where indicated in red, NX uses the associativity of the left extension line.

Ordinate Dimension dialog bar

After you select the Ordinate Dimension option, NX opens the Ordinate Dimension dialog bar. This dialog bar contains the necessary options to create ordinate dimensions.

Ordinate Dimension dialog bar Additional options become available after you define an ordinate origin and margins. See the Dimension dialog bar options for descriptions of the options.

Note: You may not create ordinate dimensions to symmetrical centerlines. You can however dimension to center marks, 2D and 3D centerlines, bolt circles, circular centerlines (arc center and tangent), and intersection points.

Note: Ordinate dimensions do not support any other Alignment Position option besides Middle Center .

Dogleg parameter options You can set any two of three dogleg parameters to define the dogleg extension. The parameters are described below.

Page 471: Drafting

Start Offset — is an offset between the dimension line and the start position of the dogleg.

End Offset — is an offset between the dimension line and the end position of the dogleg.

Angle — is the dogleg angle.

Dogleg Handles You can change the dogleg parameters by dragging dogleg handles. The system provides three handles at the dogleg start, center, and end. You can also drag the dimension line, arrow side projection line, and the dogleg angle line. The possible handle movement depends on the position of the dogleg. Below is an example for a horizontal dimension.

— Indicates Handle Location

— Indicates Text Location

You can also change dogleg parameters by entering new values in the on-screen input boxes for Start Offset , End Offset , and Angle .

Where Do I Find it? Use any one of the following methods to access dogleg parameter options.

While in an active set, choose Dimension Style →Ordinate →Dogleg on a selected ordinate dimension.

On an existing dogleg, double-click the dimension to select it, then double-click a dogleg handle to display the on-screen input boxes.

Auto Dimension Tool This option allows you to automatically create a series of dimensions to positions selected using single or rectangular selection. When you choose this option, the system displays the Auto Ordinate Dimensions dialog

Page 472: Drafting

box allowing you to specify dimension positions (arcs, control points, or arcs and control points) as well as arc range parameters (see the following figure).

For auto-dimensioning selection, you can either do rectangular selection, or select each object one by one. If you select each object one by one, you don't need to select a view first.

If you use rectangular selection, you must pick a view (by clicking the left mouse button on the view border), then drag a rectangle around the objects to dimension. If arcs are specified for selection, the system selects the center of each arc that lies inside the rectangle and meets the specified range parameters. The dimensions are then created at the nearest margin.

Note: Please note the following:

You should define the desired dimensioning parameters in the Dimension Style dialog box before clicking Auto Dimension . For example, if you want your auto dimension to contain doglegs, set the dogleg option to Infer prior clicking Auto Dimension . After clicking Auto Dimension , the Ordinate Dimension dialog bar becomes unavailable. You must click either Cancel or OK to return to the Ordinate Dimension dialog bar.

NX selects all arc centers (including circular solid edges) and control points of non-arcs within the area defined.

When the Auto Ordinate Dimensions dialog box is open, all the margins are active. NX uses the margin closest to the geometry being dimensioned.

Dragging a Rectangle Over the Objects to Auto Dimension

— System Selects All Arc Centers within Dragged Rectangle which Meet Range Parameters

The information that follows describes how to use the options in the Auto Ordinate Dimensions dialog box:

Note: If arc centers are selectable, and a center mark symbol is associated to the arc, the system dimensions to the center mark symbol.

Range Options The Less Than , Equal To , and Greater Than boxes specify a range within which NX should either select, or not select arcs. These values represent the diameters of the arcs. Each of these options contains a check box which enables the value in the associated box.

Page 473: Drafting

You may use more than one range option at a time. For example, if you wanted to limit your selection to just arcs, then only those arcs larger than .5 and less than 2.00, you would click Only Arc Centers , then select Less Than check box, and then the Greater Than check box, and type the values in the appropriate boxes (see the following figure). Note, that if you use both upper and lower range values, an arc is selected only if it satisfies both range values. In this example, arcs are selected that have diameters less than 2.00 and greater than .5. If you were to reverse the values to select arcs less than .5 and greater than 2.00, no arcs would be selected, since an arc cannot satisfy both upper and lower range values (an arc cannot be both less than .5 and greater than 2.00).

When using Equal To in conjunction with a range value (Less Than or Greater Than ), the arc must satisfy either the Equal To value or the range value. It does not need to satisfy both.

When you use rectangular selection, the system utilizes the range options. You must set these options prior to selecting with a rectangle. You may use a combination of single select and rectangular selection.

When you drag the rectangle, the system selects all arcs. NX then deselects the arcs that do not fall within the specified range. You must click Apply or OK to apply the dimensions to the defined positions.

The Effects of Doglegs on Auto Ordinate Dimensions If the Dogleg option is set to Infer when you use Auto Ordinate Dimensions, NX creates the required doglegs automatically. NX creates dimensions, beginning at the origin. As it encounters dimensions that overlap each other (see the following figure), the system begins to dogleg away from the origin.
