Introduction

MicroStation/J is a CAD Engine developed by Bentley designed to Edit and create Vector Drawings; it has features to Display Raster images too. Minimum System Requirement: 32 bit operating system 256Color monitor 32MB RAM 120MB Disk Space required Type of Drawing: Depending on the way in which the drawings are displayed and stored they are widely categorized as Vector Drawings and Raster Drawings

• Raster Drawing are drawings, which store pixel information of display hence a line would be formed by joining a series of adjacent color pixels. These are also known as Raster Images.

• Vector Drawings, In these types of drawings the lines end point would be stored

and respectively be displayed in the space. The advantage of vector are that they are very precise, can be modified easily maintain thickness through out. Vector Drawings are suitable for engineering purposes.

All MicroStation entities are known as elements, e.g. Circle, Line, Shape, etc. All Elements have some attributes. The element attributes related to display are

• Color – this controls the color of the element • Line Style – this decides the pattern of line • Line weight – This controls the line thickness • Levels – It controls some important features like visibility of the elements • Class – Again categories elements into classes

For Setting attributes Go to: Elements (Menu) -> Attributes (Also available in the Primary Tool Bar.)

About MicroStation Design File A MicroStation document file is called a design file. MicroStation's File menu has items for creating, opening, and saving design files

You cannot have more than one design file open or active in MicroStation at a time. If you open a design file when one is already active, MicroStation automatically closes the first file. However, you can view the contents of other design files by attaching them for reference to the active design.

When you create a design file, MicroStation copies one of the provided templates or seed design files. The seed file is copied to a new file name that you specify in the Create Design File dialog box.

4


To create a design file and open it as the active design file

1. From the File menu, choose New. The Create Design File dialog box opens. The default filter is “*.dgn.”

2. The file specification for the default seed design file is displayed in the Seed File section.

3. (Optional) To change the filter, choose the corresponding item in the List Files of Type drop-down list. The file list is useful for avoiding assigning the new file an already existing filename.

4. (Optional) To select a different seed design file, click the Select button and use the Select Seed File dialog box.

5. (Optional) To select a different destination disk drive, choose the desired drive from the Drives option menu.

6. (Optional) To select a different destination directory, use the Directories list box. 7. In the Files field, key in a name for the new design file.

Although the extension “.dgn” is often used to indicate a MicroStation design file, any or no extension is acceptable.

8. Click OK.

Preparing to Draw:

Except for user preferences, there are no default settings in MicroStation. The settings described in the following subsections can be saved in the design file on disk. To preserve changes to these design file settings between sessions, you must explicitly save the settings.

Seed files

When you create a design file, you identify a seed file as a template for the design file. The new design file is actually a copy of the seed file.

Seed files do not (necessarily) contain elements, but, like other design files, they do contain settings and view configurations. Having a seed file with customized settings keeps you from having to adjust settings each time you create a design file. If you wish, you can have a different seed file for each type of drawing you do.

To select a seed file

1. From the File menu, choose New. The Create Design File dialog box opens.

2. In the Seed File section, click the Select button. The Select Seed File dialog box opens. The default filter is “*.dgn.”

3. (Optional) To list all files in the Files list box, choose All Files from the List Files of Type option menu.

5


4. (Optional) To select a different source disk drive, choose the desired drive from the Drives option menu.

5. (Optional) To select a different source directory, use the Directories list box. 6. In the Files list box, select the desired seed file.

Or In the Files field, key in the name of the desired seed file.

7. Click OK.

Design plane

In 2D drafting, the MicroStation equivalent of a sheet of drafting paper is the design plane. The design plane is composed of points at which you enter data points when placing elements in a design. Each point in the design plane has associated x (horizontal) and y (vertical) positions or coordinates. The design plane, then, is simply a Cartesian coordinate system upon which your design lies.

Coordinates are expressed in the form (x,y). MicroStation's Default workspace, the point called the Global Origin (GO) is set to the design plane's exact center and assigned the coordinates 0,0.

• Any point to the right of the Global Origin has a positive x-value; any point to the left has a negative x-value.

• Any point above the Global Origin has a positive y-value; any point below has a negative y-value.

For most purposes the Global Origin in the provided seed files is fine. You may wish to change the location or coordinates of the Global Origin, though. For example, an architect may want all coordinates to be positive values. A mapper or surveyor may need to use a grid system defined by a government agency to reference all locations to a specific point.

6


When you enter a data point, MicroStation saves its coordinates as 32-bit integers. Accordingly, the design plane has 232 (4,294,967,296) points in each dimension. The distance between two adjacent points is the smallest distance MicroStation can address. This distance is one positional unit or unit of resolution (UOR). The 3D Design Cube is analogous to the 2D design plane.

Working units

Although MicroStation “thinks” in positional units, it lets you draw in “real world” units like feet and inches, or meters and centimeters. These real world units are called working units.

• Working units are expressed as master units (the largest units in a design) and fractional sub-units.

• The number of positional units per sub-unit is called the working resolution.

How working units are expressed

Distances in design files are sometimes expressed in the form of three numbers separated by colons “MU:SU:PU.” For example, “3:4:100” means three master units (MU), four sub-units (SU), and 100 positional units (PU). The table has examples of distances expressed in this form.

Working Units MU:SU:PU Distance Feet / inches / thousandths 120:10: (or 120:10) 120 feet, 10 inches Miles / feet / inches 350::6 350 miles, 6 inches Millimeters / thousandths :500: (or :500) One half millimeter Yards / feet / inches :12:8 12 feet, 8 inches Yards / feet / inches ::11 11 inches

Working resolution

Determines the precision with which elements are drawn and the working area of the design plane. The working area is the size, in working units, of the design plane; the size of the design cannot exceed the working area. Because the design plane is square, there is an inverse relationship between precision and working area.

Working units settings

Consist of working units and working resolution and are specific to a design file. The working unit settings in the discipline-specific seed files provided with MicroStation are commonly used in the respective disciplines. Some of the provided seed files have English working unit settings and others have metric settings. To easily convert back and forth between metric and English units, use working unit settings groups.

7


1. After you create a design file but before you begin to draw, you should confirm that the working unit settings provide adequate precision for your design task and a working area that exceeds the projected size of the design. Both requirements can usually be met with

Saving design file settings once you have done the settings

To preserve changes to design file settings — such as working units and coordinate readout, between sessions, you must explicitly save the settings.

To save the current settings to the active design file on disk

1. From the File menu, choose Save Settings (or press <CTRL-F>).

Selecting an element

When precision is not important, the easiest way to perform element manipulations and modifications is to use the Element Selection Tool in the Element Selection tool box (in the Main tool frame, Element Selection is the default “representative” of the Element Selection tool box). Most basic manipulations and modifications can be done with the Element Selection tool, including:

• Moving and copying • Scaling • Moving vertices • Modifying axes

When precision is important, the PowerSelector tool is useful for distinguishing the elements on which to perform manipulations and modifications.

The PowerSelector tool is used to select and deselect multiple elements in a variety of ways.

The Attribute List field in the PowerSelector settings window allows unique methods for selecting elements. The active set is denoted by a list of values that ends with a semi-colon. You can edit these values before the semi-colon to build a subset. Only the elements that match the existing values are kept, the others are removed from the set. Pressing <Return> or <Tab> applies the subset. Switching attributes allows you to continue the process of elimination.

If values are entered after the semi-colon, PowerSelector performs a scan on the active file and all locatable reference files. A selection scan supports add, subtract and inverse selection modes. If a semi-colon is not used: PowerSelector assumes a subset if elements are selected, and a scan if nothing is selected.

The attributes Level, Color, Style, Weight, and Class will locate simple elements within a complex element and act upon the entire complex element.

17


The Types attribute supports exact matches only.

Tool Setting Effect

Method

Sets the selection method:

• Individual — selection is performed on a per element basis, as with the regular Element Selection tool. If you enter a data point but miss an element, the Block Method activates.

• Block Inside — all elements inside the defined block are selected. • Block Overlap — all elements inside and overlapping the defined

block are selected. • Shape Inside — all elements inside the defined shape are selected. • Shape Overlap — all elements inside and overlapping the defined

shape are selected. • Line — elements are selected by drawing a line that intersects them.

Mode

Sets the objective of using the tool:

• Add — selects elements. • Subtract — deselects elements. • Invert — toggles the selection status of an element (selects deselected

elements and deselects selected elements). • Clear/Select All — deselects all selected elements, or selects all

elements if no elements are currently selected.

Attribute

Clicking the Show More Information arrow expands the Tool Settings window to reveal the Attribute combo box and the Attribute List field.

• Level — ranges between 1 and 63. • Color — ranges between 0 and 254. • Style — Standard line styles range between 0 and 7. • Weight — Line weight ranges between 0 and 31. • Type — Element type numbers as defined in the on-line Reference

Guide. • Class — Element class values as defined in the on-line Reference

This completes the Pattering Lab. You are now ready to continue with the next lesson: Reference Files

38


Reference Files This lab is designed to give you practice working with reference files. You will attach and manipulate reference files. 1. Create a new 2-D design file. From the File pull-down on The Command Window

select the New item (or use the shortcut Ctrl-N). To name the file, use xxbor.dgn inserting your initials in the position of the X’s.

2. Once in the design file, select the Settings pull-down. Select the Working Units item.

• Key in FT for Master Units • Key in IN for Sub Units • Key-in 12 for SU per FT • Key-in 1000 for Pos Units per IN • Click OK. A dialog box will display informing you that the size of existing

elements will change. Click OK. 3. Save your settings. (From File menu click on to save settings.)

4. Draw a border. Select the PLACE LINE TOOL. Place a data point at the global origin,

to locate the lower left corner of the border. Use dimensions as shown in Illustration 1 Illustration 1

5. Exit the design file containing the border and open your subdivision design file. 6. Attach the second file containing the border as reference file to your subdivision

drawing. From Tools pull down menu, click on to Reference file tools and from this toolbox select ATTACH REFERENCE FILE TOOL.

39


7. Select your border.dgn file as the file to be attached. (You may have to change directories.) Click OK. Another dialog box will appear. This dialog box asks you to specify a logical name and description if desired. Click OK upon completion.

8. The border may not line up around your drawing. If it is not visible, use FIT ALL

TOOL. 9. If the needs to be moved use the MOVE REFERENCE FILE TOOL. It will take at

least two data points to move the reference file in response to the prompts. Refer to the Illustration 2 for the suggested position of the border.

10. Complete the title block for your drawing. Place your name, date and your company

title as shown in the Illustration 2. Use your choice of font, text size, and line spacing. Place your text on level 12.

11. Zoom in around one of the roof s that was patterned and make a saved view out of it.

(From UTILITY pull down menu, select SAVED VIEWS.) 12. Turn on level 12 13. Attach your design file containing the house saved view as a reference file (i.e. attach

the file that you are currently in to itself). Select the saved view name you created in step 11, and scale it up to 8 times. Place it to the right of your screen as an enlarged detail as shown in Illustration 3. Illustration3

40


14. The attached reference files are not displayed, execute the Attachment settings box

and display your reference files. 15. If you are satisfied with the appearance of your design up to this point, do the

following: • Compress the design • Save your settings • Make a backup copy

41


AccuDraw

Working with a mechanical engineering design, you will use MicroStation’s most powerful drafting aid, AccuDraw, in conjunction with its most flexible drawing tool, Place SmartLine.

You will draw a simple wrench for use on a bicycle. The wrench will have an open and a closed end, each designed for 1inch nuts or bolts. Here is what the final drawing will look like:

The tutorial is structured as a series of exercises that are meant to be performed consecutively. You will learn about:

• Drawing the profile • Completing the wrench • Modifying the wrench In each exercise, it is assumed that you have just completed the preceding exercise.

If you have trouble

If you have trouble when going through the lesson, doing one of the following usually helps:

• Reset, by pressing the Reset button. This is most useful when you have trouble using a tool.

• Undo, by choosing Undo from the Edit menu, or by clicking the Undo icon in the Standard tool bar below the main menu bar. This is most helpful after you finish using a tool and realize that you have made a mistake. Remember, MicroStation lets you undo more than just the last operation.

• “Undo” a change made with a view control by choosing the View Previous view control, located on the view control bar in the bottom border of each view window. This is helpful if you use a view control to zoom out or window an area and lose your bearings.

42


• Remember DO NOT RESET OR ENTER A DATA POINT UNTIL TOLD TO DO SO.

43


Exercise: Drawing the profile

You will employ a construction element as a reference center line. This construction line will be used as a drawing aid only — it will not be plotted. Open the design file, “wrench.dgn”:

1. From the File menu, choose Open. The Open Design File dialog box opens. 2. In MicroStation’s “dgn/learning” directory, select “wrench.dgn.” 3. Click the OK button.

Following are a few notes about “wrench.dgn”: The grid is displayed.

• Master units are inches. The distance between each grid reference cross is 1 inch. The grid points are 1/10th of an inch apart.

• The coordinate readout is set to Master units and uses 4 decimal places. A distance of one and one-half inches is displayed in the status bar as “1.5000”.

• Snap Lock is turned on and “Snap Divisor” is set to 2. Line segments have three snap points — one at either end and one at the midpoint. To enable snapping: From the Settings menu’s Locks sub-menu, choose Dialog. In the Locks settings box, turn on Snap Lock.

Place a line as a construction element:

1. From the Element menu, choose Attributes. The Element Attributes settings box

opens.

2. Set the Active Color to Red (3) by pressing on the small square to the right of the Color field, and dragging the pointer to the red tile in the first row of the drop-down color palette, and then releasing the Data button.

3. Set the Active Line Style to Dashed (2) by pressing on the option menu to the right of

the Style field, dragging the pointer to the menu’s dashed entry, and then releasing the Data button.

4. Confirm that the Active Line Weight is set to zero (0) by checking the value in the

Weight field. If the Active Line Weight is not set to zero, choose 0 from the Weight option menu.

44


5. Set the Active Class to Construction by choosing Construction from the Class option menu. The Element Attributes settings box now displays the settings used for the reference centerline.

45


6. In the Primary tool bar, select the Start AccuDraw tool. The AccuDraw window

opens. If the window’s fields are labeled Distance and Angle, press <space bar> to change them to x and y.

7. From the Settings menu’s Locks sub-menu, choose Grid. A checkmark to the left of

the Grid menu item indicates that Grid Lock is turned on. Grid Lock works in combination with the grid. Data points placed between grid points are moved and locked to the nearest grid point.

8. In the Linear Elements tool box, select the Place Line tool. 9. On a large grid reference point, on the far left side of view window, enter a data point.

AccuDraw’s compass appears as a dashed square at the location where you placed the data point. As you move the pointer to the right, both fields in the AccuDraw window update to show the distance in the X and Y planes from the compass to the current pointer location.

10. Move the pointer horizontally to the right of the first data point until the line highlights. This indicates the line currently under construction is now indexed to the X axis from the current compass location. AccuDraw’s Y field will display a 0 value and AccuDraw’s input focus (the place where any keyboard entry will be directed) will be on the X field.

11. Key-in 5.

Because the input focus was on the X field you do not have to choose the field to enter a value. AccuDraw anticipates your next input by placing the input focus in the appropriate place. The line is tentatively constrained at a length of 5 inches.

46


12. With X showing 5, and Y showing 0, enter a data point (i.e., click the mouse) to

accept AccuDraw’s values. 13. Reset. Start drawing the profile of the wrench:

The wrench’s profile includes the open end and the shank. When the profile is drawn, it looks like this:

1. In the Element Attributes settings box, set the Active Color to Blue (1). 2. Set the Active Line Style to Solid (0). 3. Set the Active Line Weight to 1. 4. Set the Active Class option to Primary. 5. In the Linear Elements tool box, select the Place SmartLine tool. 6. Snap a tentative point to the left end of the reference centerline, and enter a data point

to begin the Profile. If the current tentative point snap mode is not set to endpoint (icon on status bar should be the one with the dot on the end of the line) then set it by clicking on the snap mode icon and choosing the correct snap mode.

7. Move the pointer up vertically from the AccuDraw’s compass. The line should index to the vertical axis. If the dynamic line does not appear indexed (i.e., a fat, highlighted appearance) move the pointer until it is indexed. Constrained line of 5 inches. The input focus will automatically be on the Y data field of the AccuDraw window.

8. Key-in 0.5.The dynamic vertical line segment will lock to half an inch.

47


9. Enter a data point to place the segment. Continue drawing the wrench’s jaw:

1. With the dynamic smartline still preset go to the Tool Settings window and set the

Vertex Type to Rounded. 2. In the Rounding Radius field, key-in 0.1 and hit a return. 3. Click on the AccuDraw window to return input focus to AccuDraw. 4. Returning to the view window, move the pointer to the left of the AccuDraw

compass. Keep the line indexed to the compass’ X axis. 5. Key-in 1.0

Note how AccuDraw locks the horizontal element to 1 unit of length. The rounded arc vertex automatically displays.

6. Enter a data point to place the line segment.

48


Constructing the wrench’s head:

1. Returning to the Tool Settings window, set Segment Type to Arcs and Vertex Type to

Sharp. The AccuDraw drawing plane automatically switches to Polar coordinates.

2. Move the pointer to the right of the compass keeping the arc’s radius line indexed to the horizontal axis. AccuDraw displays both the indexed radius indicator line and a dynamic arc.

3. Key-in 0.9 which will appear in the Distance field of the AccuDraw window. 4. Enter a data point to define the center point of the arc. As you move the pointer to the

right a semi-circular arc is dynamically displayed. 5. Key-in a Tab to switch input focus to the Angle field. Key-in 180.

If a “circle” appears instead of the expected arc, move the pointer to the right of the AccuDraw compass. This will result in the correct element display.

6. Enter a data point to place the arc segment. Drawing the shank:

1. Switch the drawing plane coordinate system back to Rectangular (press <spacebar>). 2. In the Tool Settings window, set Segment Type to Lines. 3. Move the pointer to the right of the compass until the dynamic line is indexed to the

horizontal access.

49


4. Key-in 3.3. 5. Enter a final data point to place the line segment. 6. Reset to complete the construction of the profile. Modify the “open-end” arc radius:

The arc used to describe the outside edge of the wrench was drawn larger than necessary. The Modify Element tool is used to reduce the radius of the arc.

1. In the Modify tool box, select the Modify Element tool. 2. Enter a data point on the wrench’s outside arc profile. 3. From the Modify Element Tool Settings window, change Method to Radius, preserve

ends. 4. With AccuDraw’s input focus on the distance field (the default) enter 0.7000. 5. Enter a data point to make the change. 6. Reset.

50


51

Exercise: Completing the wrench

The first portion of the wrench is now complete. To create the other half of the wrench, a mirrored copy is made from the first half of the wrench. Mirror the wrench profile about the reference centerline:

1. In the Manipulate tool box, select the Mirror tool. 2. In the Tool Settings window, set (or confirm) Mirror About: Horizontal. 3. Set Make Copy option to on (has an X in its check box).Modifying the wrench’s arc. 4. Enter a data point on the wrench profile ( the blue element created in previous

exercise).

As you move the pointer, the mirror image of the wrench profile is dynamically displayed. The location of the pointer defines the axis that the image is mirrored around.

5. Snap a tentative point to the reference centerline (the red dashed line). 6. Enter a data point to accept the mirrored copy of the wrench profile.


7. Reset.

52


Draw the closed end of the wrench:

To complete the profile of the wrench, an arc is added at the closed end.

1. In the Linear Elements tool bar, select the Place SmartLine tool. 2. In the Tool Settings window set Segment Type to Arcs and Vertex Type to Sharp. 3. Snap a tentative point to the right end of the upper wrench profile (the horizontal line

segment). 4. Accept the tentative point to begin the arc placement. 5. To establish the center point of the arc, snap a tentative point to the right end of the

reference centerline (the red dashed line). 6. Accept the center location.

If the arc does not appear as shown in the illustration just move the pointer in a clockwise rotation about the arc’s centerpoint. This will “unwind” the arc in the right direction.

7. Snap a tentative point to the right end of the lower wrench profile. 8. Accept the arc endpoint.

Note how the AccuDraw compass appears as the endpoint of the new arc. This indicates the readiness to continue the smartline construction. However, we are done with this portion of the design so the next step is to complete the construction.

9. Reset to complete the arc.

53


10. Close the AccuDraw Window. The wrench profile is complete.

54


Create a hexagonal “closed-end” for the wrench:

1. In the Polygons tool box, select the Place Regular Polygon tool. The Place Regular

Polygon Tool Settings window opens. 2. In the Tool Settings window, set Method to Circumscribed; Edges to 6; Radius to 0.5;

Area to Solid; and Fill Type to None. 3. Snap a tentative point to the right end of the reference centerline. Wrench arc points

and finished arc. A hexagon is dynamically displayed at the location of the pointer. 4. Accept the tentative point to place the hexagon.

5. Reset. The closed end of the wrench is complete.

The wrench profile is complete and the reference centerline is no longer needed. Turn off the display of the construction element:

1. From the Settings menu, choose View Attributes. The View Attributes settings box

opens. 2. Turn off Constructions. 3. Click the All button. The reference centerline is no longer visible. 4. Close the View Attributes window. Finished arc.

55


Exercise: Modifying the wrench Link the elements into a single complex shape:

Next you will convert the two mirrored wrench halves into a single closed shape.

Link the elements into a single complex element:

1. In the Groups tool box, select the Create Complex Shape tool. 2. In the Tool Settings window set Method to Automatic; Max Gap to 0.0004; Area to

Solid; and Fill Type to None. 3. Identify the wrench’s upper shank. Enter subsequent data points to accept each new

link in the chain in order to makes up the entire wrench chain. 4. When the last data point has been entered, the entire outline of the wrench is

highlighted. 5. Accept.

Place hatching into the wrench:

Next you will place hatching into the wrench using the Association option. Any modifications made to the shape will automatically cause the hatching to be regenerated.

56


The outside profile of the wrench is a single complex shape created in previous exercise.

57


1. In the Patterns tool bar, select the Hatch Area tool. (At start-up, Hatch Area is in the

Main tool box.) 2. In the Tool Settings window, set hatching options to: Spacing to 0.125; Angle to 45;

Tolerance to 0.0; Associative Pattern to On; and Method to Difference. Difference mode hatching patterns the area between two or more closed shapes, each identified by data points. Creating a single complex element from a chain.

3. To set the hatch pattern symbology, In the Primary tool bar, set Active Color to Red

(2); Active Line Style to Solid (0); and Active Line Weight to 0. 4. Identify the wrench profile. 5. Identify the hexagon at the wrench’s closed end. This data point also accepts the

profile.

6. Accept the hexagon. Both the profile and the hexagon are highlighted. 7. Reset. The solid part of the wrench is hatched.

The line on which one of the hatch lines is placed passes through the data point you

entered to accept the profile. Next you will lengthen the span between the two ends is lengthened using the Manipulate Fence Contents tool.

58


Use a fence to “stretch” the wrench:

1. In the element Selection tool box, select the Place Fence tool. 2. In the Tool Settings window, set Fence Mode to Inside. 3. Enter a data point slightly beneath the right end of the wrench.

As you move the pointer, the fence is dynamically displayed.

4. Drag the fence block up and to the left to confine the closed end of the wrench. 5. In the Primary tool bar, select the Start AccuDraw tool. The AccuDraw window

opens. 6. In the Fence tool box, select the Manipulate Fence Contents tool. 7. In the Tool Settings window, set Operation to Stretch. 8. Enter a data point to be used as the starting location. The AccuDraw compass appears

at the data point location. 9. Move the pointer to the right of the compass indexed to the X axis. 10. Key-in 2.0.AccuDraw’s input focus will take care of putting it in the correct field. 11. Enter another data point to initiate the stretching operation. The wrench is “stretched”

2 inches to the right. The hatching is automatically regenerated. 12. Select the Place Fence tool to remove the fence. Removing the fence when you have finished prevents accidental fence operations.

59


Working with AccuDraw AccuDraw is controlled from a variety of sources. You can influence it through the use of one- and two-key sequences called keyboard shortcuts. Drawing tools, themselves, can influence AccuDraw's operation. Finally, AccuDraw itself maintains a number of user selectable options via the AccuDraw Settings dialog box.

AccuDraw supports a large number of options. However, all of these options can be placed into one of three major AccuDraw functions:

• Previewing and constraining data points • Locating the AccuDraw compass • Orienting AccuDraw's drawing plane

AccuDraw and the Popup Calculator With the popup calculator, you can perform mathematical operations on the values displayed in some MicroStation text fields, and the values adjust accordingly.

This feature is documented here as it works with AccuDraw, its use is extendable to other controls. Active Scale and Active Angle fields currently support it.

The popup calculator is supported as follows:

Dialog Box Fields AccuDraw window X / Y / Z (various) Active Angle (various) Active Scale

To use the popup calculator

1. With the input focus in a field that supports popup calculation, type any of the following: +, -, *, /, =

Type a value or expression to complete the calculation. Press <Return>, enter a data point, or click outside the popup calculator to

60


accept the calculated value. Press <Esc> if you want to reject the value.

Basic 3D Concepts This section introduces the basic concepts related to working with 3D designs.

Design cube The design cube represents a 3D design file's total volume. Points in 3D design files are defined with x-, y-, and z-values, or coordinates. 3D design files consist of a design cube in which you work. Points can be placed anywhere within the design cube, and are not restricted to a single plane.

The design cube and 2D design plane

Design cube coordinates are expressed in the form (x,y,z).

A 3D design file contains 4,294,967,296 positional units (UORs) in the x, y, and z-directions, analogous to the 2D Design Plane.

62


The global origin in the 3D seed files provided with MicroStation is located at the exact center of the design cube and assigned the coordinates (0,0,0). Any point in front of the global origin has a positive z-value and any point behind it has a negative z-value.

View volume The view volume (sometimes called the display volume) is the volume displayed in a 3D view. In most cases, only a part of the design cube is displayed in a view.

Any elements, or parts of elements, not contained in the view volume are not displayed in the view. The window area, and its Display Depth bound the view volume.

Display Depth

The distance from the front to the back of a 3D view is its Display Depth, which is bounded by clipping planes.

• The front clipping plane is the one nearest the viewer. • The back clipping plane is farthest from the viewer.

Elements in front of the front clipping plane or behind the back clipping plane are not displayed in the view, even if they are within its viewing area, regardless of how far the view is zoomed out.

Active Depth The Active Depth is the plane, parallel to the screen in a view, on which data points are entered by default. The Active Depth is perpendicular to, and is measured along, the view's z-axis. This is why it is sometimes referred to as the “active z-depth.” The grid lies on this plane as well.

63


B-Back Clipping Plane, AZ-Active Depth, F-Front Clipping Plane

The AccuDraw window in 3D

In 3D, when using Rectangular coordinates, the AccuDraw window has an additional field for the z-axis. For Polar coordinates in 3D, the AccuDraw window has the same two fields as in 2D.

Orienting the drawing plane in 3D

Learning to orient AccuDraw's drawing plane is essential to mastering 3D drawing. For example, it is easy with AccuDraw to place a non-planar complex chain or complex shape in an isometric view in any direction without reverting once to an orthogonal view. By simply rotating the drawing plane axes, you can “strike off” at a right angle to the current segment.

This is most apparent during the creation of a true 3D drawing normally portrayed as an isometric drawing — for example, a plumbing riser diagram. By starting a pipe run along one view axis and shifting it using the <F>, <S>, and <T> keyboard shortcuts, you can twist and turn the pipe through 3D space.

64


A simple plumbing riser diagram under construction showing the compass at each corner and annotation pointing out the drawing plane orientation at each vertex

This ability to adhere to the standard view axes while manipulating your drawing in a pictorial view is so important that AccuDraw maintains the current orientation from tool to tool. You can still return to the view orientation by using the <V> keyboard shortcut.

The following table summarizes the AccuDraw keyboard shortcuts available for fine tuning the drawing plane orientation so the axes point where you want them to go:

Key Effect

<V> Rotates the drawing plane to align with the view axes. Pressing this key a second time restores context-sensitive rotation.

<F> Rotates the drawing plane to align with the axes in a standard Front view. Pressing this key a second time restores context-sensitive rotation.

<S> Rotates the drawing plane to align with the axes in a standard Right view. Pressing this key a second time restores context-sensitive rotation.

<T> Rotates the drawing plane to align with the axes in a standard Top view. Pressing this key a second time restores context-sensitive rotation.

<R>,<Q> Used to quickly and temporarily rotate the drawing plane by a single point.

<R>,<A>

Used to permanently rotate the drawing plane by three points. Because it rotates the active ACS, this rotation will still be active after the tool in use is exited. If on, the tool setting Use Current Origin causes the drawing plane origin to be used as the x-axis origin, thereby eliminating the need to enter an extra data point. Of course, in many cases it is desirable to be able to define the x-axis origin at a different location than the drawing plane origin.

65


<R>,<X> Rotates the drawing plane 90° about its x-axis. <R>,<Y> Rotates the drawing plane 90° about its y-axis. <R>,<Z> Rotates the drawing plane 90° about its z-axis.

Arbitrary rotations

By default, AccuDraw orients the drawing plane to the view axes. This is in keeping with the way it works in 2D. You can return AccuDraw to this orientation at any time using the <V> keyboard shortcut.
