The following changes have been made for cast units in concrete detailing:

Family numbering is only applied for precast cast units. The top-in-form setting is only taken into account in the numbering of precast cast units. Precast components can only be applied for precast cast units. Precast manufacturing exports are only allowed for precast cast units (for example,

Unitechnik, ELiPLAN).The following improvements have been made in the Reinforced Concrete Detailing (RCD) configuration:

Cast-in-place cast units and reinforcements can now be numbered in RCD. When reinforcing precast concrete parts, conceptual reinforcements are created in RCD. It

is possible to convert the conceptual reinforcements to detailed reinforcements in the Precast Concrete Detailing (PCD) configuration.

You can now add steel embeds to cast-in-place cast units in RCD. You can now warp, camber and shorten a part using the options on the Deforming tab in

the part properties dialog box in RCD. It is now possible to create cast unit drawings of cast-in-place cast units. Precast cast unit

drawings cannot be created, and the existing drawings are only in read-only mode in RCD.

Improvements in construction management The following improvements have been made in the Construction Management configuration in Tekla Structures 17.0:

The General toolbar now contains a button for Model Organizer. The button is also available in the Full configuration.TT54765

You can use Task Manager when creating sequences in your model. You can manage the individual objects in tasks on the Objects tab of the Task Information dialog box. The Sequencer tool is not available anymore on the Tools menu.TT54439

You can now set the work plane parallel to view plane, go to View > Set Work Plane > Parallel to View Plane.TT47101

You can now create grids and add grid lines. This makes working with, for example, IFC reference models easier and more efficient as you can manually add grids to these models.TT43045

Cast units have the cast unit type part property - they are set either Cast in place or Precast. It is now important to use the correct cast unit type, because some functionalities, for example numbering, are based on the cast unit type.


The Diagnose & Repair Model tool for repairing a corrupted model database is now available on the Tools menu. TT41091

You can now export IFC, 3D DWG/DXF, 3D DGN, SDNF, and CIS/2 files.TT48507

You can now import SDNF and CIS/2 files.TT41935


GridsManaging individual objects in a task

Changes in detecting clashesClash Check Manager is now available on the Tools menu in all Tekla Structures configurations. The Clash Check tool command is not available anymore on the Tools menu. If you run clash check using the Clash Check command on the right-click pop-up menu, the results are shown in Clash Check Manager. To make more people benefit from the construction management information created using the Full and Construction Management configurations, viewer modes of construction management tools are now available. This allows the whole project team to access construction management information.

In the Full and Construction Management configurations, you can use all Clash Check Manager functions, such as, assignments, priorities, commenting, grouping and saving selected clashes for users to handle.

In the other Tekla Structures configurations, you can use the basic clash detection functions, for example, run, re-run, and save a clash check. You can also load previously saved clash checks and use the search box to find clashes based on search terms. In addition, you can view the clash information added in the Full and Construction Management configurations, such as object details, status, priority, comments, and the history of a clash.When you open Clash Check Manager in these configurations, you are in the Basic mode.


Detecting clashes

Viewing tasks in Task ManagerTask Manager is now available on the Tools menu in all Tekla Structures configurations. To make more people benefit from the construction management information created using the Full and Construction Management configurations, viewer modes of construction management tools are now available. This allows the whole project team to access construction management information.

In the Full and Construction Management configurations, you can use all Task Manager functions.

In the other Tekla Structures configurations, you can now view task schedules and task information created in the Full and Construction Management configurations. It is easy, for example, to view the schedule of your own assignments and track how a whole project is progressing.When you open Task Manager in these configurations, you are in the viewer mode.



Introduction to Task Manager

Viewing logical areas and object type categories in Model OrganizerModel Organizer is now available on the Tools menu in all Tekla Structures configurations. To make more people benefit from the construction management information created using the Full and Construction Management configurations, viewer modes of construction management tools are now available. This allows the whole project team to access construction management information.

In the Full and Construction Management configurations, you can use all Model Organizer functions.

In the other Tekla Structures configurations, you can now view the logical areas and object type categories created in the Full and Construction Management configurations. You can select, show and hide the areas and categories in your model. Logical areas and object type categories are used to create, for example, reports and drawings. You can also use Model Organizer with filters to efficiently access model information.When you open Model Organizer in these configurations, you are in the viewer mode.


Organizing the model

Improvements in snappingThe following improvements have been made to snapping in Tekla Structures 17.0:

When snapping to extension lines, it is now easier to follow an extension line as it extends past the cursor.

When snapping to an extension line that is perpendicular to the part reference line, an angle symbol is shown.


When both the Snap to extension lines snap switch and the Snap to nearest

points (points on line) snap switch are active, it is now possible to snap to the intersection of the extension line and the grid line. Snapping to the intersection also works

when both the Snap to extension lines snap switch and the Snap to intersection

points snap switch are active.

It is now easier to find the extension line in 3D view when snapping. To show the extension line, you can move the mouse pointer along the part reference line and continue in the direction of the extension.


The Snap to nearest points (points on line) switch and the Snap to lines and edges

switch are now next to each other in the Snapping toolbar . They have been grouped so that turning one of them on automatically turns the other one off.


Snapping to extension lines

Improvements in Mini ToolbarThe following improvements have been made to the Mini Toolbar in Tekla Structures 17.0:

You can now quickly show or hide the Mini Toolbar using the keyboard shortcut Ctrl+K. You can still also go to Tools > Options > Mini Toolbar to show or hide the toolbar.

You can now modify polygon welds using the Mini Toolbar.


Mini Toolbar

Font used in Tekla Structures user interface The font used in the Tekla Structures user interface now follows the Windows default system font. If you change the system font in Windows, the font used in Tekla Structures dialog boxes and other user inteface elements changes accordingly. Using the Windows default system font makes the user interface more easy to read.

Improved search in dialog box listsIn Tekla Structures 17.0, it is easier to search for the desired option from a list. You can now use more than one character to find the desired option. Previously, you could only use one character.When you enter a character in the list box, the first entry beginning with that character is shown. Entering more characters further specifies the search.

Note that if you wait too long until you enter the second or the third character, a new seach for that character starts. For example, if you search for rafters and enter ra but wait too long until entering f, the search will find the first option that begins with an f.


Dialog box elements


Improvements in FlexNet licensing Tekla Structures 17.0 works with version 17 entitlements. You need to deactivate version

16 entitlements in order to activate the version 17 entitlements. New version of Tekla Structures license server is released with Tekla Structures 17.0. The

versioning of Tekla Structures license server has been harmonized with the Tekla Structures version numbers. From now on the version number of the licensing tools refers to the Tekla Structures main version, same way as the entitlement version number.

Tekla Structures Licensing Service is now configured automatically during the license server installation. Your server computer hostname is automatically written into tekla.lic license file, and the license server manager lmgrd is set to run TCP/IP port 27007. This reduces the need to edit the tekla.lic file manually.

There is a new tab in Tekla Structures License Administration Tool. The Statistic tab shows the license usage at one view. The Statistic tab gives the total number of each configuration activated on the server, licenses in use, borrowed licenses and free licenses.

The usage of the enterprise licenses can now be controlled through tekla.opt options file. You can, for example, assign the enterprise licenses to a certain work group with the following rule:INCLUDE STD-C:VENDOR_STRING=Enterprise GROUP detailers-india

The configuration code of Construction Management has changed from ConstructionManagement to CM-C. You can use the new configuration code in tekla.opt file to control access to Construction Management licenses.

You can now run Tekla Structures license server without troubles with VPN connection.


Directory BrowserDirectory Browser finds and then opens various Tekla Structures related folders based on what kind of information you need. Using the tool you can easily check different folder paths that store the files and settings you may need to customze.To access the tool, go to Tools > Macros..., and select Directory Browser from the list.Directory Browser has two tab pages. The Basic tab stores the most common folder paths and gives an easy access to common .ini files. If you have not set up your firm or project folders, Directory Browser will prompt you to define them and will add the settings in the user.ini file.On the Advanced tab you can define the folder paths for additional folders that you may need to access, such as custom compoonents and macros.

Global and local folder for XS_MACRO_DIRECTORYThe advanced option XS_MACRO_DIRECTORY in Tools > Options > Advanced Options... > File Locations now accepts two folders: a global and a local macro folder, and finds macros in these two folders. Use a semicolon (;) as a separator. Do not define more than two macro folders. First define the global folder and then the local folder: ..\Tekla Structures\\\environments\common\macros;..\Tekla Structures\\\environments\\macros

In the Tools > Macros dialog box, you can select which macros to run by selecting the Local or Global option button. The buttons are not visible if you specify only one macro folder.

You may need administrator rights to be able to add or modify the files in some of the folders.

Please do not change the global folder. If necessary, you may change the local folder.

Certified support of 3Dconnexion 3D mouseTekla Structures has received 3Dconnexion Certification. This means that Tekla Structures is listed as a 3Dconnexion supported software on the 3Dconnexion website.The benefits of the certification are, for example,

smooth 2-axis movement translation and rotation speeds are matched and fluid axes are correctly mapped.

Improvements in 3D mouse

Other Tekla Structures 17.0 3D mouse improvements include:


New button types: BUTTON_DECREASE_FOV BUTTON_INCREASE_FOV BUTTON_TOGGLE_ROTATE BUTTON_TOGGLE_PAN BUTTON_TOGGLE_ZOOM BUTTON_ZOOM_IN_CENTERED BUTTON_ZOOM_OUT_CENTERED

You can now zoom and pan or rotate simultaneously. Use the keyword AXIS_ZOOM_CENTERED in the DirectInput.cfg configuration file for setting the centered zoom.

You can now bind macros to the 3D mouse buttons. Use the keyword MACRO in the DirectInput.cfg configuration file for binding.

You can now reread the DirectInput configuration file. This allows you to change the mouse settings and test how the settings work while Tekla Structures is running.Add Change DirectInput Configuration to a user-defined menu or toolbar, and click it after you have edited the configuration file for the changes to take effect.

You can now add a default DirectInput.cfg file to the installation. The configuration file is copied to user-defined location if no user-defined file is found.Use the advanced option set XS_DIRECTINPUT_CONFIG_DEFAULT= some file in the environment to define the location of the default configuration file.

3.3 Modeling

More colors in object representationYou can customize the color of model objects using the new Choose color... option in the Object Representation dialog box. This option gives you more freedom in visualizing the different types of objects in the model.


You can define a specific color of your own for each object group. When you click Choose color..., the Color dialog box is displayed. You can select a color either from the Basic colors palette, or create custom colors of your own. You can use an unlimited number of colors in a model. The Color list in the Object Representation dialog box shows 10 previously defined colors above the dashed line. Information about the colors that you set for the object groups is stored in the used_custom_colors.clr file, which is located in the model's attributes folder. Information about the colors that you add in the Custom colors palette is stored in the xs_user.xxx file in the model folder (xxx is your user name).



Object representation settingsCreating object representation settings

Changes in view type selection The View type selection has been removed from the model View Properties dialog box. All model views are now by default rendered. If you want to use wire frame, set the advanced option XS_ENABLE_WIRE_FRAME to TRUE through Tools > Options > Advanced Options > Model View. Rendered views:

The Autostick options in the Display dialog box are unavailable.Wire frame views:

The View type selection is available in the View Properties dialog box, and you can set the view type to rendered or wire frame.

The Autostick options are available in the Display dialog box.Both rendered and wire frame views:

The command Create Zoom Window has been removed from the View menu. You can use the zooming commands Zoom In and Zoom Out instead of Create Zoom Window.


XS_ENABLE_WIRE_FRAMEView types

New tools for creating surface viewsWith the new surface view creation commands you can pick the surface of any part, and Tekla Structures automatically creates a new aligned temporary view looking directly at the surface, fits the work area of the model to the selected part, and aligns the work plane to that surface or a user-selected edge of the surface. This makes it easier to model in bolt groups, stiffener plates, and hole penetrations on complex geometry. While you model in the newly created temporary view, you can see your modeling work being done in the original 3D view for verification.You can also use these tools to easily create views along the surface of concrete panels, slabs, columns, or beams, which makes it easy to place embeds, formwork, or wall penetrations.The commands are available in the Macros dialog box (Tools > Macros), and you can also add them on a toolbar (Tools > Customize).

To create a surface view using the toolbar:

Choose color is not available in Tekla Web Viewer. If you intend to publish the model as a web page, use only standard colors.


1. Click one of the view creation commands: To create a surface view from the part surface, click CreateSurfaceView and select

the surface of a part you want a new view to be created from. If creating the surface view from only selecting the surface does not align or orientate

the view along the edge you might want, click CreateSurfaceView_wEdge, select the surface, and pick the edge in which you want to align the view to (this means the edge that will form the X axis of the view).

Ensure that you have Snap to geometry lines /points on. This allows you to pick along an edge to define the direction.Tekla Structures creates a new temporary view with the view plane at the selected surface and the work plane changed along typically the longest edge of that face unless you chose the CreateSurfaceView_wEdge command.

2. Once the view is created, press Esc or right-click and select Interrupt to interrupt. 3. Use t he command WorkPlaneGlobal to return the work plane in the model back to the

origin and aligned with the global X,Y, and Z planes of the model.

Example Below is an example of a view that has been created with the CreateSurfaceView command.

Below is an example of using the CreateSurfaceView_wEdge command. The first image shows the snap to lines arrow. The head of the arrow represents the positive direction the x axis will be set to on the work plane. The view will be rotated to this direction in order to form the flat horizontal edge of the view. The origin of the view and work plane will be at the start of the arrow snap line. Once you have hovered over the edge and in the correct direction, click your mouse and the new view will be created and aligned to that edge.

More object properties in Model OrganizerIn Tekla Structures 17.0 there are now more properties available for the Model Organizer object pane. You can modify the object pane to better suit your needs by selecting the properties that are shown and by adding new properties. To open the Properties dialog box,

click in Model Organizer.

You have several options when adding new properties. You can load a separate file containing the properties or you can add a new row to the property list and then enter the property information.You can also add properties from a reference model. You can copy all the information of a property from the Inquire object dialog box, right-click in the Properties dialog box in Model Organizer, and select Paste external properties.In the properties list, you can sort the properties by clicking the column headings. The Report property and UDA name columns show the respective model object attribute types. Use only one of them at a time for a property. You can also search for a property using the search box.



Modifying the object pane

Checking clashes inside reference modelsThere is a new advanced option, XS_CLASH_CHECK_INSIDE_REFERENCE_MODELS, for defining whether internal clashes are checked in reference models.The default value FALSE means that clashes between reference model objects within one reference model are ignored. Clashes between reference model objects belonging to different models are detected. The value TRUE means that clashes between reference model objects within one reference model are checked.Note that this advanced option is taken into account only if the XS_CLASH_CHECK_BETWEEN_REFERENCES advanced option is set to TRUE.

3.4 Reinforcement

Defining your own reinforcing bar bending shapesIn Tekla Structures 17.0 you can define your own custom reinforcing bar bending shapes with the Rebar shape manager tool, and thus increase the amount of recognised reinforcing bar shapes. Custom bending shapes are useful when Tekla Structures does not recognize a reinforcing bar bending shape and assigns it UNKNOWN bending type.When you define your custom shapes, an XML file called RebarShapeRules.xml is created in the currect model folder.By default, Tekla Structures installation package already contains an XML file called RebarShapeRules.xml. The file is located in ..\Tekla Structures\\environments\\system folder, and it contains the most typical reinforcing bar shapes of your environment. These catalog shapes can be appended with your custom shapes.The custom bending shapes can be used in bending schedules and pull-out pictures in the same way as the predefined, Tekla Structures internal bending shapes.


To define your own reinforcing bar bending shape:1. Set the advanced option XS_USE_USER_DEFINED_REBARSHAPERULES to TRUE to enable

the user-defined bending shape recognition.2. Select reinforcing bars in the model.3. Go to Tools > Macros..., and select RebarShapeManager.4. Click Run.

Rebar shape manager opens, and lists the selected reinforcing bars on the Model rebars list.Model rebars list shows the ID number and the bending shape code of the reinforcing bars.Catalog shapes list shows the shapes that exist in the RebarShapeRules.xml file.

5. Select one unknown shape from the Model rebars list.

Alternatively, you can first open Rebar shape manager and then select reinforcing bars in the model. Click Get selected to add the reinforcing bars to the Model rebars list.


6. Define the needed bending shape information. Use the Shape code box to enter a shape code for an unknown shape. Bending shape rules lists the rules for the bending shape. You can add or a delete a

rule by clicking the Add and Delete buttons. If you modify the Bending shape rules, the Reset button restores the original rules.

Select the Require hooks check box if you want to define different shape codes for two bars that otherwise have exactly the same geometry, but the other bar has hooks and the other one does not have hooks. By default, the hooks are not required and the check box is not selected.

Use Bending schedule fields to define the content for a bending schedule. Right-click a field to select the shape properties, or to enter a formula.

If you have defined the shape code for a selected reinforcing bar and you have modified the shape code, bending shape rules or the bending schedule field definitions, click Update to update the existing shape code defintion.

7. When you have finished defining the new shape, click Add to add the bending shape definition to the RebarShapeRules.xml file.

8. Click Save to save the RebarShapeRules.xml file.By default, the file is located in the current model folder.Next time you create, for example, a bending schedule, Tekla Structures uses the updated bending shape information and recognizes the added bending shape and assigns a correct bending shape code for it.

Modeling direction

When the reinforcing bar shape is being defined, the start or end of the modeling direction is always sorted based on the bending angles and/or leg lengths. This means that the shape code will be the same regardless of the modeling direction.Bending radius is not taken into consideration in the sorting, and therefore it cannot be trusted that radius 1 is always less than radius 2 or vice versa.


User-defined reinforcing bar bending shapesDefining your own reinforcing bar bending shapesDefining rules for reinforcing bar bending shapes manuallyReinforcing bar bending shape rule settingsXS_USE_USER_DEFINED_REBARSHAPERULES

Improvements in bending radiusesYou can now define a bending radius separately for each reinforcing bar bend. To do so, enter several values in the Bending radius field. Separate the values with a space. Use the new template attribute DIM_R_ALL to report the multiple values of the bending radiuses in drawings and reports.

The names of the Bending schedule fields (A, B, and so on) are used in templates and reports. To make sure that also old reports work corrcetly, we recommend that you use the same DIM_XX fields as used in the rebar_schedule_config.inp file.

You need to change the bending shape rule, enter a shape code or require the hooks to enable the Add button.

3.5 Drawings

Improvements in associativity and cloningThe following improvements have been made to associativity and cloning in Tekla Structures version 17.0.

3D views in GA drawings

All objects are associative in 3D views also in general arrangement drawings.


Intelligent cloning

Intelligent cloning is now enabled by default. This means that dimensions, marks, welds, texts, associative notes, and graphical objects are adjusted per their associations during cloning. The advanced option XS_INTELLIGENT_CLONING_ALLOWED is not available anymore. TT52695

Views View frame is now updated if necessary when additional dimensions are created for new parts during drawing update or cloning. View frame is the gray box around the view.TT53592

Now the view boundary of main views is enlarged if necessary when new parts are added to an assembly, or when a cloned drawing contains more parts than the cloning template. View boundary is the dashed frame around the contents of a drawing view.TT53980

Sometimes section views and detail views expanded in cloning. This was caused by the view boundary becoming too big. If the view was associated to a reinforcement bar in the cloned drawing, sometimes a wrong reinforcement bar was used, which caused the view to expand. This has now been fixed.TT56952

A new advanced option XS_DETAIL_VIEW_MAX_GROWTH was added in Tools > Options > Advanced Options > Drawing View. The default value is 1.2 that prevents the view from growing more than 20%. If you set this advanced option to 0.00, the view size does not have any upper limit.TT56952

The view placing during drawing update and cloning has been improved. Now views retain their relative location to other views better when view sizes change or when the drawing contains lots of views.TT53547

When cloning, if there are new single parts in the resulting drawing, single-part views are now created correctly for the new parts.


TT36256

Views for included single parts are now placed correctly after cloning and when you select Create single-part views from the pop-up menu.TT54623

When you clone an assembly drawing, and you have set Dimensions to Create in cloning settings, the single-part views no longer get outside of their container.TT59187

Dimensions The new advanced option XS_DRAWING_COMBINE_ADDED_DIMENSIONS controls whether added dimensions are merged to existing ones in updated or cloned drawings. Added dimensions are not merged to existing ones if this advanced option is set to FALSE through Tools > Options > Advanced Options > Drawing Properties. The default value is TRUE. TT50191

Internal bolt dimensions of added bolts were sometimes missing after drawing update. This has now been fixed.TT53653

Bounding dimensions (first and last dimension points) are now cloned correctly. They were sometimes missing from manually added reinforcing bar dimensions in cloned drawings.


TT50695

Dimensions located on the drawing sheet are now cloned to new drawings.TT54624

Duplicate dimensions are no longer created for bolts in updated or cloned drawings.TT54308

All obsolete dimension points are now removed after update or cloning. Previously, not all obsolete dimension points were removed, especially if the point was located near the center plane of the main part.TT55233

Now angle dimensions are correct after intelligent updates.TT50456

Dimension tags sometimes disappeared when dimensions were merged, or when more dimension points were added to the dimension line. This has now been fixed.TT55232

Leader line handle points in merged weld marks

Merged weld marks now maintain leader line handle points in cloning. Previously, straight lines were drawn.


TT54901, TT55537

Associative notes to reinforcing bars

Associative notes of reinforcing bars are now associative no matter where you pick to add the note, for example, edge or center line.TT55938

Reinforcing bar orientation

Reinforcing bar orientation is taken into account in cloning. Previously, it could happen that the dimensions were associated to a wrong reinforcing bar with a totally different orientation. TT57397

Automatic cloning

Assembly drawing was not automatically cloned when an assembly position was changed in the model, and manual cloning was needed. This has now been fixed.TT59585

When a drawing was automatically cloned, the drawing was marked incorrectly as PARTS MODIFIED in the Drawing List. Now the automatically cloned drawings are marked correctly as CLONED.TT54914


XS_DRAWING_COMBINE_ADDED_DIMENSIONSXS_DETAIL_VIEW_MAX_GROWTH

Improvements in visualizing drawing object associativityCorrect associations improve the reliability of drawing updates and cloning.The visualization of the drawing object associativity has been improved in the following way:

Associative symbols are shown only when you select a drawing object, for example, a dimension. Earlier associative symbols were shown for all associative objects at the same time.

Objects that do not have valid association get a ghost associative symbol and a question mark. These symbols are shown constantly. This makes it easier to find objects that need attention.

Shapes (lines, rectangles, etc.) get ghost associative symbols only when they are created or selected. The symbols are not shown constantly, because shape objects are often intentionally not associated to anything.


You can still turn off the associative symbols by selecting Tools > Options > Associative Symbol (Shift + A), but the new functionality makes it very practical to have the symbols always on.

Associative symbols:

Below is an example of ghost associative symbols. The ghost symbols are shown even though the dimension is not selected.

In the image below, the selected 2'-8 dimension line has two associative symbols shown, and the 4'-0 dimension line has a ghost associative symbol indicating that it is not associated to anything.



Drawing associativity

Improvements in controlling dimension tag mark contentIn addition to the user-selectable dimension tag mark content, there is some content in the marks that is automatically created based on the dimension end point locations. In Tekla Structures 17.0, you can use the new setting Exclude parts according to filter on the Tags tab of the Dimension Properties dialog box and select a filter that removes the desired automatic content, such as marks and counts from the tag. This feature is useful, for example, when the dimensioning line is associative with more than one object.The new feature uses drawing view filters. Before you can remove content from the tag, you need to create a drawing view filter for that purpose.


The example below shows a tag that automatically contains concrete parts.

In the example below, a drawing view filter concrete is created.


The created drawing view filter was used to remove all concrete parts from the tag content.


Adding tags to dimensionsCreating view filters in drawingsExample: Removing dimension tag content

Moving the end of the dimension lineYou can now move the end of the dimension line orthogonal to itself outside the part by dragging it from the handle. The dimension tags are moved together with the end of the line. This is useful when the tags would otherwise overlap part geometry or other objects, such as dimensions or marks. The dimension tags are visible while you drag. This new feature also supports the requirements of the EN ISO 3766 standard regarding the dimensioning and marking of reinforcing bars.


Limitations You can move the end of the dimension line in all straight dimensions, except elevation dimensions.


Moving the end of the dimension line

New angle dimension type: Triangle with degreesThe Dimension Properties dialog box now contains a new angle dimension type: Triangle with degrees. This new option was also added to the Mini Toolbar.


General dimension propertiesSelecting the dimension type

New tool for dimensioning center of gravityIndicating the center of gravity (COG) is now part of the Eurocode. In Tekla Structures 17.0, you can indicate the location of the center of gravity in single-part, assembly, and cast unit drawings by creating COG dimensions and a COG symbol at the center of gravity. You can also create COG dimensions in section views. COG dimensions will be automatically updated if the single part, assembly, or cast-unit changes. The COG dimensions can also be cloned.To create COG dimensions:

1. Double-click the Create COG Dimensioning toolbar command .2. Modify the creation, dimensioning and symbol options and dimension attributes as

required.


3. Click OK.4. Pick the first point to specify the origin of the dimensions. The origin is the point from

which you want to measure the location of the center of gravity. This point must be located within the view frame.

5. Pick the second point to place the dimensions. This point may fall outside the view frame.

The example below shows the created dimensions.


6. When the dimension is selected, handles are shown at the dimension origin and the dimension location. You can drag these handles to adjust the origin or the location, or move them using the standard editing commands.

Limitations If a drawing containing COG dimensions is copied or linked to another drawing, such as a multidrawing, the COG dimensions will not be copied.

COG dimensions cannot be created in general arrangement drawings or multidrawings.


Dimensioning center of gravityCreating a user-defined menuManaging toolbarsAdding dimensions

New tool for dimensioning spiral stirrup reinforcement groupsYou can now add dimensions to spiral stirrup reinforcement by using the Create StirrupDimPlugin application.Creating the dimensions successfully with this application requires that you model the reinforcing bar group using the creation method By exact spacings in the Reinforcing Bar Properties dialog box.Before you can use this feature, add the Create StirrupDIMPlugin command to a toolbar or to the User menu through Tools > Customize.


To add the dimension, select the reinforcement, click the command Create StirrupDimPlugin that you added on a toolbar, or select the command from the User menu, and then pick a location where you want to place the dimension.

If you want to change the center-to-center distance letter, double-click the stirrup dimension and change the letter.

You can also load special stirrup dimension properties and modify them:1. Open the Dimension Properties dialog box. 2. Load the StirrupDim properties.3. Change the settings as required, for example, the arrow type.4. Save the properties with the name StirrupDim.5. Double-click the stirrup dimension.6. In the Stirrup dimensioning plug-in dialog box, click Modify.You can also add texts to the stirrup and load special stirrup text properties:1. Open the Text Properties dialog box.2. Load the StirrupDim properties.3. Change the settings as required.4. Save the properties with the name StirrupDim.5. Click OK and add the text.

New tool for creating drawing views for reinforcement meshesYou can now create drawing views each containing one reinforcement mesh by using the macro RebarMeshViewCreator through Tools > Macros. You can create mesh views in general arrangement and cast unit drawings.The mesh view contains the overall mesh length and width dimensions, and dimension lines for wire spacing in horizontal and vertical directions. Also the wire sizes are displayed. To create a reinforcement mesh view in a drawing:1. Open the drawing and select the meshes.2. Click Tools > Options to go to the Macros dialog box.3. Click RebarMeshViewCreator and Run.4. You have the following choices in creating mesh views:

If you want to create a mesh view for each separate mesh in the current drawing, select Create mesh view for all meshes in the drawing and click Create.

If you want to create a view for only certain meshes, select Create view for selected meshes.

If you already have the views and just want to add dimension lines and diameters in the views, select Create annotations for selected meshes.

5. Click Create.You may need to modify the view scale of the created mesh view.

Example Below is an example of the created mesh view.

3.6 Import and Export

Layout Manager - new tool for using model data on siteLayout Manager makes it possible to use accurate model data on the construction site. You can export model data from Tekla Structures to an external device, Trimble LM80, and import data from Trimble LM80 back to Tekla Structures. Using real model data on the site brings considerable improvements to construction productivity and accuracy. There are fewer errors as you do not need to manually calculate distances and angles from plans, and, for example, pull tapes to measure distances. To start Layout Manager, go to Tools > Layout Manager.... To export model layout data, you need to define layout points and/or layout lines in your model. You can define them using the LayoutPoint and LayoutLine tools in the Component catalog.


When you have defined the points and lines in the model, refresh the view in Layout Manager to be able to manage the layout points and lines. You can for example, create groups, name the groups, and define the point class, size and shape.

Improvements in IFC object conversionThe following improvements have been included in the IFC object conversion in Tekla Structures 17.0:

The Convert IFC objects tool can now be started directly from the Tools menu. Previously the Convert IFC objects tool was started from the Tools > Macros dialog box.

You can convert plates, slabs and footings into native Tekla Structures objects. The conversion is now more reliable. You can copy properties from the IFC object property sets to user-defined attributes of the

converted Tekla Structures objects in the Settings > IFC object convertor settings dialog box.

Part naming is now based on object type definitions.


Converting IFC objects into native Tekla Structures objects

New contour marking settings for NC files You can add contour marking information to your DSTV and NC files with the new contour marking settings available in Tekla Structures 17.0. You can add contour marking to both main and secondary parts.You can define how the parts are contour marked: by punching, by using powder or both.To access the cntour marking settings, click File > Export > Create NC Files... and click the Contour marking... button in the NC Files dialog box.


Tekla Structures displays contour marking as thick red lines in the model view.


Contour marking

Improvements in Export EliPlan file (68)The Export EliPlan (68) component enables you to transfer model data to Elematic ELiPLAN, a software for resource planning, scheduling, and management for precast concrete fabricators. The following improvements have been included in the Export EliPlan file (68) component in Tekla Structures 17.0:

New option on the Parameters tab

You can now define which material classes to exclude with the new option List of classes to be ignored (Material). Separate the classes by a space.


You can now define which secondary concrete parts to exclude with the new option List of classes to be ignored (Concrete). Separate the classes by a space.

New Plotter data tab

You can use the options on the new Plotter data tab to define how to export data on cutouts and embeds.

Plotter data export

The plotter item dimensions for wall and sandwich wall products are exported differently than for slab products: the dimension LENGTH is always zero and the three other dimensions (WIDTH, HEIGHT and THICKNESS) have respective values.

New options on the Data content tab

You can now set the reinforcing bar length unit with the option Unit for rebar length. Tag for lifters You can define whether to export the cast unit position number, or the assigned control

number (ACN) with the option Position number type. You can use the newCalculate wall net area at option to control from which face of the

part the net area for wall and sandwich panels will be calculated.

Exporting stairs The formwork plane is now oriented and aligned based on the largest face of the main part. The length and width are calculated based on the main part boundaries in this aligned

coordinate system. The height is calculated automatically based on the actual part: it is the minimum thickness

at the center half area (0.25*L 0.75*L) of the part geometry.

Other improvements

The top-in-form setting is now taken into consideration when exporting wall products. This change affects plotter data (the coordinate values for openings and embeds) of wall and sandwich wall product types.

The total thickness of walls is now calculated for sandwich elements in the following manner:

Width (W) and height (H) are calculated based on extreme dimensions of all concrete parts of the cast unit. The origin for the plotter data is the lower left corner of the W*H box.

Thickness is now calculated based on extreme dimensions of concrete parts whose area is 25% or more of the gross area of the whole cast unit. This way corbels or any other small parts are not counted in the thickness.

Openings of all larger plates are exported in the plotter section. Earlier only main part openings were exported.


Overview of ELiPLAN import and export

Improvements in Unitechnik export (79)Description The Unitechnik export (79) component enables you to transfer model data to factory

automation and ERP systems efficiently. The following improvements have been included in Unitechnik export (79) in Tekla Structures 17.0 :

New options on the Reinforcement tab

You can define whether the reinforcing bars are sorted according to their angle direction with the new option Rebar direction angle limit.

You can define whether to add wires to the reinforcement mesh that stabilize the mesh with the new option Add mesh stabilizing wires. This is useful when you have meshes with large openings.

You can define the maximum spacing of the wires that stabilize the reinforcement mesh with the new option Stabilization wire max spacing.

Other improvements

The direction of bent reinforcing bars is now correct correct in the export.


Now also the Z coordinate of the mesh is written in the STEELMAT block in the Unitechnik file.

The direction of braced girders is now calculated correctly. The advanced option XS_UNITECHNIK_OFFSET_MESHES now works correctly. Volume information is now exported correctly. The exclusion of the first and last reinforcing bars from a reinforcing bar group is now

taken into account in the export. Cast units, whose cast unit type is cast in place, are not exported. Only precast cast units

are exported.


Exporting Unitechnik

Improvements in BVBS exportThe following improvements have been included in the exporting of reinforcements to BVBS format in Tekla Structures 17.0:

BVBS export locates now in File > Export > BVBS... BVBS version 2.0 is now fully supported. You can now define what to export: reinforcement in all cast units, reinforcement in

selected cast units or only selected reinforcements. You can define how to export: all reinforcements to the same file, or if a separate file is

created for each cast unit. You have more options how to name the files: by their cast unit position or by their

assembly control number. You can include drawing data in the export.

Changes in Eurocode load modeling and load combinations The Eurocode model building code has been updated to enable the using of Eurocode on a national level by using localizable standard files for different National Application Document requirements.

Eurocode settings

The following changes have been made to Eurocode settings (available in Tools > Options > Options... > Load modeling > Eurocode tab):

You can now enter a Reliability class factor. Support for generation according to the national annex (using standard files) has been

enhanced. New load group types Special permanent load and Ice load have been added.

Special permanent loads can be used in exceptional loading conditions, for example, where a minimum load factor of zero (0.0) needs to be adopted for certain permanent loads instead of the typical 0.9..1.0 range, for a safe load condition.

Customizable load group types have been added. You can use the customizable load group types as a workaround when unsupported load modeling code needs to be used. These load groups are regarded as variable load groups when generating the Eurocode load combinations.


Load combination generation

The following changes have been made to load combination generation settings (available when clicking the Generate... button in the Load Combinations dialog box):

Options for SLS - Serviceability limit state, Accidental loads, Earthquake loads and Minimum permanent load with lateral loads only have been added.You can select the Minimum permanent load with lateral loads only option if it is considered safe to exclude lateral load combinations where permanent loads have the maximum factor. In other words, the number of generated load combinations is reduced when this option is selected.

Options for Load groups and Generate wind also in the opposite direction have been removed.

You can access the Options dialog box by clicking the new Options... button.


Load combination

You can now add a scaling factor. This corresponds to the Eurocode reliability class factor.

3.8 System Components

Improvements in Seam Applicator (1)Seam Applicator (1) modeling tool has been improved in Tekla Structures 17.0. The improvements enable a better usage of the Seam Applicator (1) with deformed, for example, cambered parts.

Seam handle points

When Seam Applicator (1) is used with a cambered double tee plate, the seam handle points are now located correctly.

New options on the Parameters tab

You can now use short seams in Seam Applicator (1). Use the following new options to control the seam creation.

With the Number of copies option you can define the number of seams.


With the Distance to first seam option you can define the distance between the double tee slab edge and the first seam start point.

With the Spacing value option you can define the space between the seams. With the Copy at equal distances option you can define whether seams are created at

equal distances.

Custom seam definition

To be able to use Seam Applicator (1), you need to have a custom seam. When you define your custom seam in Custom Component Wizard, make sure that you select the Allow multiple instances of connection between same parts checkbox on the Advanced tab. This way you can ensure that the short custom seams behave correctly in the model.

Improvements in Precast stairs (65)The following fixes and improvements are available in the Precast stairs (65) modeling tool in Tekla Structures 16.1 and 17.0.

Stairs tab The Stairs tab has the following new options: A new option for foot creation. By default, the foot is created.

You can now enter negative values for foot nose depth. Entering a negative value cuts the first step.TT52479

On the Attributes tab, Prefix for Landings, Stringers and Ant-skid is now correctly set. TT43301, TT43300

Previously a small ridge was created at the bottom step. Now the rigde is not created anymore. TT51090

Improvements in Rectangular column reinforcement (83)The following fixes and improvements are available in the Rectangular column reinforcement (83) modeling tool in Tekla Structures 16.1 and 17.0.

Side bars tab You can now define multiple side bars with different diameters.

Equally sloped


TT49832

Stirrups tab The Stirrups tab has a new option Create as one group that allows you to create stirrups as one large stirrup group with different spacings, or as smaller reinforcing bar groups for each zone.TT54991

Strirrup attributes tab

The different zones now have zone numbers.

TT56222

Fixes When you modified the component main part in a model that was created in a previous version, unwanted side bars were created. This has now been fixed.TT54374

Top bars are now created correctly.TT54964

Intermediate links are now created correctly for side bars 1 and side bars 2. If both side bars 1 and 2 are used, the intermediate links are created only for side bar 1.TT57003


The side bars are now placed evenly between the main bars if you leave the spacing field empty and the spacing option is set to symmetrical.TT55806

4 Fixes

4.1 IntroductionThis section contains descriptions on the numerous fixes and improvements that have been included in Tekla Structures 17.0. Also fixes made for upgrade packages since Tekla Structures 16.1 are included.The number after the description of the fix (for example TT12345) is the development item number of that particular fix. Your local Tekla office may have referred to this number when you have for example submitted a maintenance request.

4.2 General

Fix listFiltering The user-defined attributes in the Part category properties are now shown correctly as

labels instead of user-defined attribute names.TT57942

Previously, when you created a view filter and applied the filter and the view properties, the filter was not used when you created a new view. This has now been fixed.TT57939

When filtering objects using a selection filter, you can now use the template properties for assemblies and cast units without a prefix, for example WEIGHT, if you have the Select assemblies switch active.TT57897

When a part belongs to several assemblies or tasks and you create rules for filtering, all the rules must now apply at least in one of the assemblies or tasks the part belongs to for filtering to succeed.TT58047

Selecting objects In the plane view, with XS_SOLID_USE_HIGHER_ACCURACY set to TRUE, you could not always select a beam with a rounded corner profile. This has now been fixed.

TT57868

The Select objects in assemblies selection switch no longer selects assemblies when you use the Ctrl + A shortcut.TT53491

Welds The Weld Properties dialog box in the model and the Weld Mark Properties dialog box in the drawings have changed. The option Intermittent has been removed, and the option Stitch weld has been added.

To get a staggered intermittent weld (stitch weld), set Stitch weld to Yes. To get a non-staggered intermittent weld and show the pitch in the drawing, set Stitch

weld to No and set Pitch to a value greater than 0.0. If your model has been created with Tekla Structures version 15 or older, you can continue

using the Stitch functionality as before, and your welds are shown correctly. If your model has been created with Tekla Structures 16.0 or 16.1 versions older than 16.0

SR4, 16.0.5, 16.1 SR3, or 16.1.3, you should check that the welds are correct. The welds are converted automatically in the following way:

Model welds: Intermittent welds are automatically converted into Stitch welds if the Above setting for Intermittent was Yes.

Manual welds in drawings: Intermittent welds are automatically converted into Stitch welds if both the Above and Below setting for Intermittent was Yes.

Below is an example of a staggered intermittent weld (stitch weld):

Below is an example of a non-staggered intermittent weld.

Copying and moving objects

You can no longer activate the Copy and Move command before selecting objects.TT53719

TEKLA STRUCTURES 17 67Fixes

Snapping The last picked point remains visible when the part is created and it can again be used as a reference point when picking the next point.TT57472

Multi-user mode When the path in the Look in box did not have a backslash \ at the end, it was not possible to change the server or open a a model in the multi-user mode. This has now been fixed.TT57725

Moving objects in magnetic planes and grids

When moving selected objects away from magnetic planes or grids, the reinforcing bars and cuts attached to the selected object are moved as well. Magnetism is now by default disabled for these objects.TT58205

Using a second display

You can now select dates in dialog boxes on the second screen.

Enhanced tooltips are now shown on the second screen.

Setting the location of objects.inp

If you did not set the advanced option XS_PROJECT, XS_FIRM or XS_INP to point to any folder, Tekla Structures tried to search the objects.inp file in the root of the current drive. The objects.inp should not be read from the root of the current drive unless the proper advanced options point there. This has now been fixed.TT58942

General settings for system and custom components

The settings on the General tab now work correctly for custom and system components.TT58969

FLEXnet licensing

If you had a Tekla Structures license server installed on a computer, Tekla Structures did not start correctly on the computer if a VPN connection was active. This has now been fixed.TT54329

4.3 Modeling

Fix listReference models

Inquiring reference model objects now works in the same way whether you use the Inquire command from the pop-up menu or toolbar icon.TT54359

You can now change the visibility of locked reference models.TT53834

68 TEKLA STRUCTURES 17Fixes

In some cases there was an application error when you tried to open a hidden IFC reference model. This has now been fixed with improved diagnose and repair model functions.TT58204

Part properties When you change the profile of a concrete column m
