Release Notes

1

Tekla Structures 12.0 Steel Detailing Tekla Structures version 12.0 is a main release and contains many new features and fixes.

Compatibility

Tekla Structures 12.0 is compatible with all previous versions. You can open and work with existing models using Tekla Structures 12.0. Note the following issues: •

Updating drawings created with an older version of Tekla Structures in Tekla Structures 12.0 may cause problems. We recommend that you complete any drawings you have started using your current version or recreate the drawings using Tekla Structures 12.0.

•

To avoid conversion problems, always open a model created with an older version of Tekla Structures as a single-user model first.

•

We recommend that you always check that custom components created in older versions work correctly in the new version of Tekla Structures. When you open custom components made with an older version of Tekla Structures in the Custom component editor, Tekla Structures asks whether you want to update the component if the new version contains such improvements which require the update. If you do not update the component, it works in the same manner as in the version where it was originally made, but you do not gain the benefits of the new improvements. If you choose to update the component, you need to check and sometimes even recreate dimensions depending on the improvements. When you delete a dimension and create a new one (even with the same name), also the equations containing the dimension need to be edited because the dependency created by the equation is lost when a dimension is deleted. You can recreate the dimensions and edit the equations easily in the Custom component editor. Release Notes Tekla Structures 12.0 Steel Detailing

5

We suggest that you complete any models you have started using your current version. Once you save a model in Tekla Structures 12.0, you can no longer open it in older versions of Tekla Structures.

Installing

Tekla Structures setup creates a new subfolder for Tekla Structures 12.0. You need Windows Administrator rights to install Tekla Structures 12.0. This ensures that all Windows system folder *.dll files are updated.

Topics

This chapter is divided into following sections: • • • • • •

Improvements in creating, opening, and saving models It is now easier to create and open a model, and to save a model with a different name. Release Notes Tekla Structures 12.0 Steel Detailing

7

Creating a new model

Enter the location for the model in the Save in field, or accept the default location, which is the location entered when Tekla Structures was installed. (The default location in the installation is C:\TeklaStructuresModels). Click the Browse button to open the Browse For Folder dialog box, where you can browse for a folder or create a new folder. Use the Model Type field to define whether the model is a single-user or a multiuser model. For a multi-user model, enter the name of the server in the Server name field.

Opening a model

To open a model, click File > Open. To browse for a model, click the Browse button to open the Browse For Folder dialog box. The information in the Designer and Description columns comes from the Project properties dialog box.

To open a single-user model as a multi-user model:

8

1.

Select the model in the Open dialog box and right-click.

2.

Select the Open as multi-user model option.


3.

Enter the name of the server in the Server name field. Click OK.

To open a multi-user model as a single-user model: 1.


2.

Select the Open as single-user model option.

When you open or create a model, the Open and New dialog boxes now include a list of the most recently used models. Saving a model with a different name

To save a model with a different name, click File > Save as and enter a name in the Model name field. Click OK.


9

Improvements in working with objects.inp file The Tekla Structures installation automatically merges any user-defined attributes you have previously defined into the objects.inp file. It searches for the objects.inp file in the following folders, in this order: Folder

Defined by variable

Model Project

XS_PROJECT

Firm

XS_FIRM

System

XS_SYSTEM

inp

XS_INP

The user-defined attributes it finds are added to the user interface. If the same attribute name exists in more than one objects.inp files, Tekla Structures uses the attribute from the first read file, according to the search order defined above. For more information on how to use the objects.inp file, see Adding properties.

Gradient background color in model views Use the new option to create a gradient color background in a model view to ensure parts drawn in a single color are visible in the view. 10


To set the colors for a gradient background, set the following variables in Tools > Advanced options > Model view:

•

XS_BACKGROUND_COLOR1: left-top corner.

•

XS_BACKGROUND_COLOR2: right-top corner.

•

XS_BACKGROUND_COLOR3: left-bottom corner.

•

XS_BACKGROUND_COLOR4: right-bottom corner.

Enter the colors as RGB (Red Green Blue) values. The scale is from 0 to 1. For example, 1.0 1.0 1.0 is white and 0.0 0.0 0.0 is black. To use the traditional single-color background, use the same value for all four variables. Close and reopen the view to activate the changes. To restore default values, clear the values in all four variables.


11

Icons in menus Menus now include the command icons, which makes it easier to locate icons on toolbars:

Templates and reports Listing the main part first The variables XS_PRIMARY_PART_FIRST and XS_PRIMARY_PART_FIRST_PART have been removed from the Advanced options dialog box. The variables are no longer needed in Template Editor 3.20 or 3.30 as you can define the template so that main part is listed first in part lists. To do this:

12


1.

In Template Editor 3.20 or 3.30, add the value field MAIN_PART to PART row.

2.

Drag the MAIN_PART field to the top of the search order in the Content browser.

3.

Select descending sort order by: • •

4.

Double-clicking the SIMILAR_TO_MAIN_PART field to open the Value Field Properties dialog box, and selecting Descending in the in the Order field.

If desired, select the Hide in output field.

If the assembly contains more parts which are similar to the assembly main part, use the template attribute SIMILAR_TO_MAIN_PART: 1.

In the Template Editor, add value field SIMILAR_TO_MAIN_PART to PART row.

2.

Drag the SIMILAR_TO_MAIN_PART field to the top of the sort order in the Content browser.

3.



4.


5.

The attribute returns 1 if the position number of the given part is the same as the position number of the main part in the assembly.

Miscellaneous fixes •

You can now use the attribute MODEL_PATH in all content types to find the path to the current model, for example C:\TeklaStructuresModels\New Model 1\.

•

You can now also use the attributes TITLE1, TITLE2 and TITLE3 in template rows.


13

Miscellaneous New Features Tutorial Tekla Structures 12.0 includes a New Features Tutorial, which presents features released in Tekla Structures 11.1, 11.2, 11.3 and 12.0. Each feature contains a description with pictures. Some features also include interactive video lessons that show you how to use the new feature. To access the New Features Tutorial, click Help > Learning Center > New Features Tutorial.

Performance improvements The following now work faster and use less memory: • •

Array of objects (29) component Associative drawings containing objects created with Array of objects (29).

Rollover highlight The rollover highlight makes it easier to select objects, by highlighting each part in yellow as the pointer moves over it. To switch this feature on, click Setup > Rollover highlight.

To switch off the rollover highlight, click Setup and deselect Rollover highlight..You can also use the keyboard shortcut H to turn the rollover highlight on or off.

Log file • 14

The message panel now displays also the time.


•

When you use the Tools > Show log file command to display the log file, Tekla Structures now scrolls to the end of the file automatically.

Managing views Selecting views

Selecting visible and named views is now easier in Tekla Structures 12.0. The arrow buttons you use to open and close views in the Views dialog box are now only active when you have selected a view.


15

Creating views

16

When you create a view using Views > Create view > Grid views, the grid is now selected automatically if there is only one grid in the view. If there are several grids, Tekla Structures prompts you to select a view:


Bringing a view on top

Now when you select a view in the Visible views list in the Views dialog box, the selected view moves to the top. If you have selected multiple views, all selected views will be moved up, with the first one on the list on top. Also, when you select a view in the model, it is automatically selected in the Visible views list.

Navigating in the model Navigating in the model is smoother when you are for example rotating a large model, because Tekla Structures now draws the model first in wire frame as you are moving the model.

Re-displaying warning messages Tekla Structures displays warning messages when necessary, for example when you are about to copy or move objects outside the work area. To prevent Tekla Structures from displaying the warning messages again, select the Do not show this message again checkbox.

To re-display the warning messages, press Shift when the warning message should appear, for example when you are copying or moving objects outside the work area, and Tekla Structures displays the warning message again.


17

1.2

Modeling

Nested assemblies Description

You can now add sub-assemblies and parts to already existing assemblies. A sub-assembly is an assembly that is added to another assembly to form a hierarchical assembly. We use the term nested assemblies to describe this type of assembly. Using nested assemblies is useful when you are modeling split trusses, brackets, railings or pipe racks, for example. A sub-assembly is treated in the same way as an assembly in Tekla Structures: •

It gets its own assembly mark

•

It appears in lists of materials in templates and reports.

You can create a separate assembly drawing of a sub-assembly. For more information, see Nested assemblies in drawings (p. 36).

18


Example of a nested assembly:

Selecting assemblies

Activate the Select assemblies switch on the Select toolbar so that you can select any level of a nested assembly, from the highest, through the subassemblies, down to single parts and bolts. The level of the assembly you have selected is displayed on the status bar. With this switch active, each assembly is highlighted as you move the pointer over it. To move to a specific level in the assembly, with it highlighted, press Shift and scroll the mouse wheel.


19

To be able to select objects in assemblies, activate the Select objects in assemblies

switch on the Select toolbar.

For more information on how to select assemblies, see How to select objects in the Modeling manual.

20


Assembly properties

To view the properties of an assembly, select it, right click and select Properties... from the pop-up menu.

You can also define user-defined attribute values for assemblies in the same dialog box. Modifying assemblies

The right-click pop-up menu also includes several new options, which you can use to modify assemblies:


21

These options are also on the main menu, under Detailing > Assembly. You can modify assemblies by: • • • •

Adding objects to assemblies Removing objects from assemblies Exploding assemblies Changing the assembly part

You can combine assemblies in the following ways: • • •

Add and connect parts as secondary parts to an existing assembly Add and connect assemblies as sub-assemblies to an existing assembly Join existing assemblies together without adding any loose parts

For more information on the different commands to use when working with assemblies and cast-units, see Cast units and assemblies. Numbering of nested assemblies

22

Sub-assemblies are numbered in same way as assemblies. Define the prefix, start number and name for the assembly in the assembly properties dialog box.


Filter

In Tekla Structures 12.0 it is not yet possible to view or select filter by assembly user-defined attributes or by nested assemblies. User-defined attributes

For information about defining user-defined attributes for assemblies, see Userdefined attributes.

Grid line labels always visible Grid labels are now always visible when the grid lines are visible. This allows you to zoom in and still know where you are in the model.

To modify the font used in grid labels, use the variables XS_DEFAULT_FONT and XS_DEFAULT_FONT_SIZE in Tools > Advanced options > Model view. You can now use special characters, such as umlauts, accents, and circumflexes, as well as combined characters, such as e acute, in grid labels. Release Notes Tekla Structures 12.0 Steel Detailing

23

Create, select, and modify single grid lines In addition to creating entire grids, you can now create single grid lines, and select, modify, copy, and move individual gridlines. Gridlines now also have handles. Creating single grid lines

24

To create a single grid line: 1.

Go to Points > Grid line or click the Create grid line

2.

Select the grid.

3.

Pick the first position for the grid line.

4.

Pick the second position for the grid line.

Grid and grid line properties

Define the properties of the grid line in the Grid line properties dialog box. For more information, see Grid properties in the Modeling manual. If there are skewed grid lines in the model, setting the grid properties back to the original settings is not possible. To revert to the original settings, delete the skewed grid line first and then modify the settings. Release Notes Tekla Structures 12.0 Steel Detailing

select switches to select

Working with grid lines

For more information on creating, modifying and deleting single grid lines, see Working with grids in the Modeling manual.

Magnetic grid planes The Magnetic grid plane and Extension for magnetic area options have been added to the Grid dialog box.

• • •

Checking the location of grid planes

Save the model before editing magnetic grids and grid planes. Rotating a magnetic grid may not yet function correctly in Tekla Structures 12.0. Avoid overlapping of magnetic grid planes. When needed, modify the grid planes in several steps to prevent the overlapping.

You may sometimes need to check the location of grid planes for example to see if parts are close enough to a magnetic grid plane that you have moved. To do this: 1.

Go to Tools > Advanced options > Model view and set the variable XS_GRID_PLANES_VISIBLE_WITH_USERPLANES to TRUE.

2.

Go to Properties > View...

3.

Click Display...

4.

In the Display dialog box,select the Construction planes checkbox in Visibility.

Improvements in grids

26

•

Edit > Undo works on grids and grid lines.

•

You can use copy and move commands on grids. For example, copy an entire grid by selecting the grid and using the Edit > Copy > Translate... command.


Add surface treatment to the entire surface of a part You can now add a surface treatment to the entire surface of a part by using the command. For more information, see Create part surface treatment in the online help. Create part surface treatment

3.

Right-click and select Delete from the pop-up menu.


Selecting a profile The Select profile dialog box has been improved to make it easier to select a profile for a part or a component object. •

Library and parametric profiles are not in separate lists any more, but they are displayed in the same tree structure.

•

Only the relevant profiles for a steel object are displayed on the Select profile dialog box.

For more information on selecting a profile and defining the material of profiles, see Profile in the Modeling manual.

28


Warping steel parts You can now use the warping functionality also in Steel Detailing configuration. To warp a steel beam: 1.

Double-click the beam to open the Beam properties dialog box and go to the Deforming tab.

2.

In the Start field, enter the angle of the beam at its start point, relative to the part reference line.

3.

In the End field, enter the angle of the beam at its end point, relative to the part reference line. For example, to warp the beam 40 degrees at the start point, enter 40 in the Start angle field and 0 in the End angle field.

4.

Click Modify to warp the beam.

5.

Click OK to close the Beam properties dialog box.

Rotating by entering numeric values in the fields that define rotation in system components still works in the same manner as before.


29

Points not created automatically at ends of parts Tekla Structures no longer automatically creates points at the ends of parts. This uses less memory and reduces processing time. It also means that you do not have to redraw the view as often. If you need a point at the end of a part, you can still create it manually. For more information, see Creating points in the Online help.

You can use part handles and snapping to create and move parts. See the following examples. Select handles

30

To select the handles of a part: 1.

Select the part.

2.

Hold down the Alt key and drag the pointer from left to right to select the part. Tekla Structures displays the handles of the part. The handle at the end that was the first point picked to create the part is yellow and the handle at the other end is magenta.


Move objects

By selecting handles you are able to, for example, move objects more easily. 1.

Select both of the objects by pressing the Ctrl key and picking the objects.

2.

Hold down the Alt key and drag the pointer from left to right to select both parts again.

3.

Select the handle in the middle of the two objects and right-click.

4.

Select Move > Translate from the pop-up menu and enter coordinates to move the two objects.

5.

Click Move. Tekla Structures moves the two objects.


31

Snap to reference points

To make it possible to pick part handles, activate the Snap to reference points switch on the Snap toolbar. As you move the pointer over a part handle, the snap symbols appears. Left click to select the part handle.

Part reference lines

When you pick two points to position a part, these points form the part reference line, and handles appear at the line ends. You can snap to and pick these handles.

You can define the visibility of the part reference line in the Display dialog box. To show the part reference line:

How to select objects in the online help. Snapping in the online help.

Object representation To create customized presentation of objects in Tekla Structures 12.0, use object representation settings. You can use the object representation settings in the following ways: •

Modify the color of objects in the model view. The Object representation dialog box replaces the Colors dialog box, which was available in previous versions.

•

Modify the visibility of objects in the model view.

•

Create customized presentation of defined object groups.

To open the Object representation dialog box, click Setup > Object representation...:

For more information on how to use the object representation settings, see Object representation settings and Object representation example in the online help. Release Notes Tekla Structures 12.0 Steel Detailing

33

Object groups are set of rules with which you group objects by selected properties and conditions. Use the object groups: •

In Object representation dialog box to control the visibility and coloring of objects in all views.

•

In 4D tool, in the Project Manager configuration.

For more information on object groups, see Object groups and Object group rules in the online help.

Miscellaneous Numbering •

When you use the Clear numbers command, Tekla Structures now displays a message after numbers have been cleared.

Views •

If you try to open more than nine views, Tekla Structures now displays a warning message.

•

Curved parts with profiles that had small values for size were displayed as straight lines in rendered views. This has been fixed.

Surface treatment •

The Select button next to the Material option in Surface treatment properties dialog box is now grayed out when it is not possible to select a material.

Lotting •

34

When you used the Lotting dialog box to create lots, Tekla Structures displayed weight in kilograms, regardless of the unit set in Tools > Units and decimals dialog box. This has been fixed.


Sketching •

Opening and closing the sketch editor sometimes took a long time in large models. This has been fixed.

Numeric snapping You can now start entering the coordinates in the Enter a numeric location dialog box by pressing the decimal key on the numeric pad first.

1.3

Drawings

Saving and freezing associative drawings When you have frozen a drawing in Tekla Structures 12.0, the changes that you make to associative objects afterwards in the model are will no longer appear in the drawing. When you change a drawing and then save it, Tekla Structures asks you whether you want to keep the changes. To prevent the drawing from being updated automatically, select the Disable automatic updating checkbox:

You can still open a general arrangement drawing, unfreeze it, and then re-open it to automatically update the drawing with recent changes.


35

To re-enable automatic updating in a frozen drawing: 1.

Go to Drawing > List... to open the drawing list.

2.

Select the drawing.

3.

Right-click and select Freeze > Off from the popup menu.

Previously when you updated an assembly, single-part or cast unit drawing without freezing the drawing, the drawing was re-created. Now the drawing is no longer re-created. This means that you must know whether the changes should be shown when you are updating the drawing. To recreate the drawing:

2.

Select the drawing you want to recreate.

3.

Right-click and select Recreate from the popup menu.

Highlight changes in associative dimensions (p. 49) in the Release notes.

Nested assemblies in drawings You can create assembly drawings of sub-assemblies. Creating sub-assemblies in the model allows you to produce less complicated drawings, which are easier to read and to understand. This reduces the risk of errors in the shop.

36


This assembly drawing of a truss is complicated and hard to read.

This assembly drawing of part of the same truss was created using a subassembly. It is much easier to read.

Marks

You can define the visibility, content, and appearance of marks for sub-assemblies in assembly drawings. You can also use part marks to display the assembly hierarchy in general arrangement drawings. For more information, see Mark content in the Drawing manual.

Bolts and welds

You can define the visiblity of bolts and welds separately for sub-assemblies in the Bolt properties and Weld properties dialog box.

Dimensioning

You can also define the dimensioning properties for sub-assemblies in assembly drawings. For more information, see Dimensioning nested assemblies in the Drawing manual.

Sub-assemblies in templates and reports

With Tekla Structures you can produce templates and reports that show the hierarchical structure of nested assemblies. For more information, see Producing reports on nested assemblies.


37

Anchor bolt plan An anchor bolt plan is a type of general arrangement drawing that displays the the layout of anchor bolts for a structure.

You can automatically create anchor bolt plans in Tekla Structures 12.0. For more information, see Creating anchor bolt plans in the Drawing manual. You can create both enlarged views and detail views in anchor bolt plans. Tekla Structures groups together identical detail views, so that they only appear once in a drawing. If detail views are not included in a drawing, Tekla Structures displays bolt sizes in the enlarged view. 38


Display large dimension values more clearly You can now use different number formats for dimensions to make large dimensions easier to read in shop and erection drawings. For example you could format 15432 to appear as 15,432 or 15 432. To do this, select the Use grouping checkbox in the Dimension properties dialog box and select a format.


39

Use the variables XS_DIMENSION_DIGIT_GROUPING_CHARACTER to define the separator and XS_DIMENSION_DIGIT_GROUPING_COUNT to define the number format (in Tools > Advanced options > Dimensioning: general).

40


Improvements in level marks The General tab in the Level mark properties dialog box now includes fields that enable you to define the appearance of level marks:

For information, see Create > Level mark in the online help.


41

Define elevation level You now have the option to define the elevation level in general arrangement drawings and in drawing views also according to the view plane. The datum point for general arrangement drawings is set automatically when creating floor plan views. This saves your time and avoids errors during drawing creation. To define the datum level: 1.

Go to Properties > Drawing...

2.

Click View... to display the view properties dialog box.

3.

In the Attributes tab, do one of the following: •

•

To set a specified datum level, select Specified in the Datum point for elevations field. Then enter a specific value in the Datum level field. To set the datum level according to the view plane, select View plane in the Datum point for elevations field.

Create plate side marks on dimension leader lines You can now create plate side marks on dimension leader lines. Plate side marks indicate whether the dimension point is to the face or center of, for example, a plate, web or flange. This is particularly useful: • •

In complex drawings In large-scale drawings, where it can be difficult to see which part a leader line is pointing to.

To create plate side marks:

42

1.

Click Properties > Dimension... to open the Dimension properties dialog box.

2.

In the Plate side marks section of the Marks tab, set Type to Specified.

3.

Define the properties of the plate side marks if required.


For more information, see Marks in the Drawing manual.

Improvements in section symbols New options in the Section symbol properties dialog box allow you to define arrow head size, arrow length, and the distance between the symbol and the section:


43

Define the appearance of the arrow head symbol You can now also define the appearance of the arrow head symbol in the Tools > Advanced options > Drawing properties dialog box using the following variables: •

XS_SECTION_SYMBOL_LEFT_ARROW_SYMBOL Modify the value for a different appearance, for example sections@0.

•

XS_SECTION_SYMBOL_RIGHT_ARROW_SYMBOL Modify the value for a different appearance, for example sections@1.

If you do not set these variables, Tekla Structures uses the traditional style arrow head symbol in the drawings.

In the example above, the variables XS_SECTION_SYMBOL_LEFT_ARROW_SYMBOL and XS_SECTION_SYMBOL_RIGHT_ARROW_SYMBOL have been set to sections@2. This section view symbol includes the location of the section view. If the arrow length is equal to zero, Tekla Structures places the text in the middle of the arrow symbol. Otherwise Tekla Structures places the text along the cut line. 44


Aligning section symbols The variable XS_ALIGN_CUT_SYMBOL_BY_VERTICAL_LINE in the Tools > Advanced options > Drawing properties dialog box only works on when you open drawings created with Tekla Structures 11.3 or older in Tekla Structures 12.0. Set the variable to TRUE, to position the cut symbol on the vertical line. Leave the variable blank to offset the symbol from the vertical line by the size of the arrow multiplied by 1.25.

Here the variable is set to TRUE. Use this option to indicate the exact location of the section view.

Here the variable has been left blank. This is useful when the direction is more important than the location.

The variable XS_ALIGN_CUT_SYMBOL_BY_VERTICAL_LINE is effective now only when you are converting a drawing created with Tekla Structures 11.3 or older into Tekla Structures 12.0 (or greater). You no longer have to restart Tekla Structures to activate changes to this variable.


45

Group identical objects on the same dimension line You can now group identical parts, bolts, components, and cuts or shapes on the same dimension line. You can choose to automatically create dimension line tags, or to define the contents of tags manually. To group identical objects on one dimension line: 1.

In the drawing, right-click and select Properties... from the pop-up menu to open the drawing properties dialog box.

2.

Click Dimensioning... to open the dimensioning properties dialog box. Go to the Dimension grouping tab. You have the following options: •

Activate dimension grouping: Select which objects you want to

group. • •

Grouping properties: Indicate the elements that must be identical. Automatic tagging: Indicate the information to include in dimen-

sion line tags that are created automatically.

46


The dimension line tag indicates the quantity of objects included in the dimension line. To define the symbol that is displayed between the quantity and the automatic tag text, use the variable XS_DIMENSION_GROUPING_COUNT_SEPARATOR in Tools > Advanced options > Dimensioning: general. The default value is x. To define what information to include in a dimension line tag: 1.

Double-click the dimension line whose tag you want to modify.

2.

In the Dimension properties dialog box, go to the Marks tab.

3.

In Tags, replace the << Automatic >> value with the required text.

4.

Click Modify.


47

48


Highlight changes in associative dimensions To have Tekla Structures highlight the dimension text that has been changed and dimension points that have been moved when you update associative drawings, set the variable XS_HIGHLIGHT_ASSOCIATIVE_DIMENSION_CHANGES to TRUE in Tools > Advanced options > Dimensioning: general.

For more information, see Highlight changes in associative dimensions in the Drawing manual.

Miscellaneous New part mark leader line type There is a new part mark leader line type, which allows you to align a part mark in the center of the face of a part.


49

Dimensions

50

•

Occasionally adding or removing dimension points removed the whole dimension. This has been fixed.

•

The RD symbol was sometimes omitted from running dimensions. This has been fixed.

•

When you create a dimension with three or more points using the Create > Dimension > Free command and end the command on the same point as the previous dimension, the dimensions are now on the same line.


Drawing views •

Drawing views no longer overlap templates in assembly drawings.

•

To rollback the Copy > Translate and Move > Translate command to work as it did in Tekla Structures 11.1 and earlier, set the variable XS_DRAWING_NO_SCALING_FOR_COPIED_OR_MOVED_OBJECTS to TRUE. With this variable set, when you copy or move drawing objects from one drawing view to another, they change size according to the scale of the view.

Associativity •

Now associative symbols are also created correctly for level marks.

•

When you changed the profile of a part, the hatch pattern did not always adjust to fit the shape of the new profile. This has been fixed.

•

The y coordinate for assembly overall dimension was sometimes calculated incorrectly which caused associativity not to work. This has been fixed.

•

Associativity works now correctly also when the start and end point of a reference line are in the same location.

Intelligent cloning •

Sometimes part marks in single-part drawings were incorrect when you cloned single-part drawings and the variable XS_INTELLIGENT_CLONING_ALLOWED was set to TRUE in Tools > Advanced options > Drawing properties. This has been fixed.


51

Plotting and printing •

You can now define plot origin offset separately for each plotter in the Plotter catalog dialog box.

The new options replace the variables XS_PLOT_ORIGIN_MOVE_X and XS_PLOT_ORIGIN_MOVE_Y. However, setting the variables in Tools > Advanced options > Plotting will override the settings in the Plotter catalog dialog box. •

Using the variables XS_PLOT_ORIGIN_MOVE_X and XS_PLOT_ORIGIN_MOVE_Y also affected the scale of the plot. This has been fixed.

Part marks Merged part marks are now placed correctly when you change the part mark

leader line type.

52


1.4

Import and export

Miscellaneous Location of the origin in DXF and DWG drawings In Tekla Structures 12.0, when a view on a Tekla Structures drawing is moved the origin for the Xref is calculated differently than before. This makes sharing Tekla Structures drawings much easier: you no longer need to adjust the origin when you export to DWG or DXF. In previous versions you sometimes had to adjust the origin when the view had been moved during the modeling process.

Exporting round tubes to NC files •

Bolt holes in unwrapped round tubes are now ignored when you export to an NC file.

•

When the variable XS_DISABLE_NC_FACET_FIX was not set, the xy coordinates of skew edges were calculated wrong in some cases, for example when the end of the tube was cut with a perpendicular round tube.

IFC •

Tekla Structures 12.0 supports the IFC 2X3 schema in IFC exports.

•

Arc-shaped walls are now displayed correctly in IFC reference

imports.

Web Viewer •

If you try to publish a model as a web page with Web Viewer using the Selected parts option in Publish as Web page dialog box without selecting any parts, Tekla Structures displays a warning message does not publish the model.


53

DSTV •

The DSTV file header was not correct when you used the variable XS_USE_NEW_PLATE_DESIGNATION. This has been fixed.

CHS profiles with cuts •

1.5

The variable XS_TUBE_UNWRAP_WITH_CUT_HOLES is now set to FALSE by default. Set the variable to TRUE to include cut holes in workshop drawings or NC files of unwrapped CHS (circular hollow section) profiles.

Custom components

Define and create connections for custom parts You can now define a custom connection, seam or detail so that when you use component in a model, you can pick custom parts as the main and/or secondary parts. You do not have to pick each part within the component. This is useful when modeling window details in a multi-layer panel when the panel is a custom part, for example. To define a custom connection, detail or seam for custom parts, use the custom component wizard and pick the custom parts as main or secondary parts. For more information on defining custom components, see Defining custom components in the online help. When you are using the custom connection, Tekla Structures accepts only custom parts as input parts if you have defined the connection with a custom part as an input part. Use the Custom component editor to edit the properties of custom parts. For more information, see Editing custom components in the online help.

54


Miscellaneous Improvements in the usability of custom components •

Now you only have to click the Modify button once in any custom component dialog box to apply changes. In previous versions, you sometimes had to click Modify repeatedly if a component had many dependencies. To define how many loops Tekla Structures makes to solve dependencies in custom components, use the variable XS_CYCLIC_SOLVER_MAX_LOOPS in Tools > Advanced options > Modeling properties. The default is 2.

•

When a custom component is not working correctly and the problem is with the equations, Tekla Structures now displays error messages in the log file that help you recognize the problem source. To see the log file, click Tools > Display log file > Log file...

Fixes •

When you selected a custom seam, its handles were not displayed. This has been fixed.

•

When you selected a nested custom detail, the handles of the custom detail were not displayed. This has been fixed.

•

The Variables dialog box in the Custom component editor includes a new value type, Factor. This is a decimal value without type. You can set the number of decimals for the value type in Setup > Units and decimals dialog box.

•

Now when you create custom components, the custom component objects get the current phase number. Release Notes Tekla Structures 12.0 Steel Detailing

55

•

Occasionally, adding a custom component in a skewed position generated an application error. This has been fixed.

•

You can now automatically import a set of custom components and sketches when you create a model. To do this, edit the variable XS_UEL_IMPORT_FOLDER in the Tekla Structures batch file to point to the folder that contains the custom components and sketches.

•

Now when you reopen the Variables dialog box, all the equations are shown even if the result of the equation cannot be calculated.

•

If the reference points you picked for a custom part were not at the center of the bounding box, the custom part was not positioned correctly. Now when you define a custom part, its coordinate system is in the center of the bounding box. Offsets are calculated from the center of the bounding box. When you edit a custom part created in an earlier version of Tekla Structures, Tekla Structures asks if you want to use this new method of positioning custom parts. If you do, you will also need to open any nested custom components in the custom part and select to use the new method.

1.6

Components

Miscellaneous Component catalog •

It was not possible to use the Paste command on the right-click popup menu in the thumbnail view of the component catalog. This has been fixed.

Error flags in connection lists •

56

Connection lists now also list connection flags correctly for Excel design also when the result is 4.


Connections Gusset plate connections In gusset plate connections you can now define the distance of the first bolt for brace2 and brace3.

This new option is available in: • •

• • • • •

•

Bolted gusset (11) Tube gusset (20) Corner tube gusset (56) and (57) Wraparound gusset (58) Hollow brace wraparound gusset (59) Wraparound gusset cross (60) Gusseted cross (62) Corner wrapped gusset (63)

Tapered Column-Beam Stub (150) •

You can now create a splice connection for a haunched built-up stub.

•

The lower flange is now aligned properly at the splice also when you are not using a haunch.

•

The lower flange backing bar occasionally clashed with the diaphragm, column or panel part. This has been fixed.

US Splice connection (77) •

The connection now also works with beams that are over 2000 mm high.

•

When you do not specify a part mark series for the non-welded splice plates, the default options are now taken from the Pos3: Loose parts option in the Options dialog box.

•

The splice is now also created correctly when the primary beam is haunched at the opposite end from the splice.


57

•

There is a new option for the location of the splice gap: to fit the primary part.

Column with shear plate (131) •

When a two-sided shear plate connection was created, the length of the two plates differed by the length of the taper extension entered on the Picture tab. This has been fixed.

•

When you use double shears with a hollow tube, the gap is now correctly offset to the outside.

Weld preparation (44) •

Weld preparation angles are now read from the correct fields and cre-

ated correctly.

Welded shear plate (43) and Stiffened shear plate (17) •

If the stiffener was thicker than the flange of the connecting beam, there was a gap between the plate and the flange. This has been fixed.

Shaped valley cleat (8) •

58

The connection now works correctly regardless of the profile of the secondary part.


Winbrace connection (110) •

You now have the option to enlarge the slot made in the tube bracing.

Portal bracing (105) •

The connection now takes the correct part prefixes from the Setup > Options dialog box.

Apex haunch (106) •

The default profile name is now haunch.

Stiffened shear plate (17) •

Tekla Structures now creates the slots in the correct locations.

Details Handrailing (1024) The toe plate created could not be included in an assembly. This has been fixed.


59

Stiffeners (1003) and Multiple stiffeners (1064) Previously, when you re-ran these details without making any changes to them, you had to update the single-part drawing of the stiffener. Now if nothing has been changed, the update is not needed.

Box column base plate (1066) •

Various issues concerning weld preparation, height of ribs, hole type and size and column fittings have been fixed in the Japanese environment.

•

One side of the column was weld prepped at 45 degrees regardless of what angle you specified. This has been fixed.

Inner diaphragm (1059) •

Double bevel cut weld preparation is now created correctly for each side of the primary column and the angle of the lower bevel cut is now taken from the correct field.

U.S. Base plate (1047) •

When you change bolts to anchor rods or anchor rods to bolts, the bolts are now created and rotated correctly.

•

When you use the option Square cut corners (1-4) Tekla Structures now cuts the correct corner of the base plate.

•

You can now create oversized holes in the cast plate.

•

In the details, plate washers are now part of the anchor rods assembly.

Stiffened base plate (1014) •

60

Welds are now created in the correct position.


Stair base detail (1043) •

The detail includes new options to define the distance between the beam and the plate for top, left, and right sides.

Stairs (S71) We suggest that you always use the Stairs (S71) detail instead of Stairs (S82) to create stairs in Tekla Structures. •

The Stairs (S71) detail includes all the options available in Stairs (S82) and also some additional options. It also includes fixes for deficiencies found in Stairs (S82).

•

You can now create steps using custom parts or seams with Stairs (S71). This will enable you to model accurate stairs with grating, end plates and bolts.


61

Cold rolled Fixes

62

•

The Cold Rolled Overlap (1) component now also works correctly when used with columns with a profile of WB900 or larger.

•

The Ayrshire Diagonal Tie - Column (81) component has been renamed Ayrshire Diagonal Tie - Column/Rafter (81). The component now also works correctly with rafters.

•

Now when you use the Metsec panel connection rail (31) component, you no longer receive unnecessary file transfer warnings.


2

Tekla Structures 12.0 Precast Concrete Detailing Tekla Structures version 12.0 is a main release and contains many new features and fixes.

Compatibility

Tekla Structures 12.0 is compatible with all previous versions. You can open and work with existing models using Tekla Structures 12.0. Note the following issues: •

Updating drawings created with an older version of Tekla Structures in Tekla Structures 12.0 may cause problems. We recommend that you complete any drawings you have started using your current version or recreate the drawings using Tekla Structures 12.0.

•

To avoid conversion problems, always open a model created with an older version of Tekla Structures as a single-user model first.

•

We recommend that you always check that custom components created in older versions work correctly in the new version of Tekla Structures. When you open custom components made with an older version of Tekla Structures in the Custom component editor, Tekla Structures asks whether you want to update the component if the new version contains such improvements which require the update. If you do not update the component, it works in the same manner as in the version where it was originally made, but you do not gain the benefits of the new improvements. If you choose to update the component, you need to check and sometimes even recreate dimensions depending on the improvements. When you delete a dimension and create a new one (even with the same name), also the equations containing the dimension need to be edited because the dependency created by the equation is lost when a dimension is deleted. You can recreate the dimensions and edit the equations easily in the Custom component editor. Release Notes Tekla Structures 12.0 Precast Concrete Detailing

63

We suggest that you complete any models you have started using your current version. Once you save a model in Tekla Structures 12.0, you can no longer open it in older versions of Tekla Structures.

Installing

Tekla Structures setup creates a new subfolder for Tekla Structures 12.0. You need Windows Administrator rights to install Tekla Structures 12.0. This ensures that all Windows system folder *.dll files are updated.

Release Notes Tekla Structures 12.0 Precast Concrete Detailing

•

Tekla Structures 12.0 installation includes new SafeNet Sentinel driver 7.22, which allows both USB and LPT hardware locks to work. Sometimes you may need to install the harware lock driver manually. In Tekla Structures 12.0, the manual installation is no longer located in the ...\nt\dongle folder. You can now start the up-to-date hardware lock driver installation manually from the C:\TeklaStructures\License\Sentinel_setup folder. Double-click the file C:\TeklaStructures\License\Sentinel_setup\setup.exe to start the manual installation.

Working with single-user and multi-user models You no longer have to choose single or multi-user mode when starting Tekla Structures. When you create a model, use the the Model Type option in New dialog box to create the model as a multi-user model or as a single-user model.

It is now possible to open a any model in either single or multi-user mode. Select the mode by selecting an option on the right-click popup menu in the Open dialog box:


65

You no longer need to use the variable XS_SERVER identify the server that contains the multi-user database.

Improvements in creating, opening, and saving models (p. 66)

Improvements in creating, opening, and saving models It is now easier to create and open a model, and to save a model with a different name. Creating a new model

Enter the location for the model in the Save in field, or accept the default location, which is the location entered when Tekla Structures was installed. (The default location in the installation is C:\TeklaStructuresModels). Click the Browse button to open the Browse For Folder dialog box, where you can browse for a folder or create a new folder. Use the Model Type field to define whether the model is a single-user or a multiuser model. For a multi-user model, enter the name of the server in the Server name field.

Opening a model

66

To open a model, click File > Open. To browse for a model, click the Browse button to open the Browse For Folder dialog box. The information in the Designer and Description columns comes from the Project properties dialog box.


To open a single-user model as a multi-user model: 1.

When you open or create a model, the Open and New dialog boxes now include a list of the most recently used models. Saving a model with a different name

To save a model with a different name, click File > Save as and enter a name in the Model name field. Click OK.

Improvements in working with objects.inp file The Tekla Structures installation automatically merges any user-defined attributes you have previously defined into the objects.inp file. It searches for the objects.inp file in the following folders, in this order:

68


Folder

Defined by variable

Model Project

XS_PROJECT

Firm

XS_FIRM

System

XS_SYSTEM

inp

XS_INP

The user-defined attributes it finds are added to the user interface. If the same attribute name exists in more than one objects.inp files, Tekla Structures uses the attribute from the first read file, according to the search order defined above. For more information on how to use the objects.inp file, see Adding properties.

Gradient background color in model views Use the new option to create a gradient color background in a model view to ensure parts drawn in a single color are visible in the view.


69

To set the colors for a gradient background, set the following variables in Tools > Advanced options > Model view:

•

XS_BACKGROUND_COLOR1: left-top corner.

•

XS_BACKGROUND_COLOR2: right-top corner.

•

XS_BACKGROUND_COLOR3: left-bottom corner.

•

XS_BACKGROUND_COLOR4: right-bottom corner.

Enter the colors as RGB (Red Green Blue) values. The scale is from 0 to 1. For example, 1.0 1.0 1.0 is white and 0.0 0.0 0.0 is black. To use the traditional single-color background, use the same value for all four variables. Close and reopen the view to activate the changes. To restore default values, clear the values in all four variables.

70


Icons in menus Menus now include the command icons, which makes it easier to locate icons on toolbars:

Templates and reports Listing the main part first The variables XS_PRIMARY_PART_FIRST and XS_PRIMARY_PART_FIRST_PART have been removed from the Advanced options dialog box. The variables are no longer needed in Template Editor 3.20 or 3.30 as you can define the template so that main part is listed first in part lists. To do this:


71

1. 2.

In Template Editor 3.20 or 3.30, add the value field MAIN_PART to PART row. Drag the MAIN_PART field to the top of the search order in the Content browser.

3.


4.



If the assembly contains more parts which are similar to the assembly main part, use the template attribute SIMILAR_TO_MAIN_PART: 1. 2.

In the Template Editor, add value field SIMILAR_TO_MAIN_PART to PART row. Drag the SIMILAR_TO_MAIN_PART field to the top of the sort order in the Content browser.

3.



4.


5.

The attribute returns 1 if the position number of the given part is the same as the position number of the main part in the assembly.

Miscellaneous fixes

72

•

The attributes PREFIX and SERIAL_NUMBER have been added for REBAR content type.

•

You can now use the attribute MODEL_PATH in all content types to find the path to the current model, for example C:\TeklaStructuresModels\New Model 1\.

•

You can now also use the attributes TITLE1, TITLE2 and TITLE3 in template rows.


Miscellaneous New Features Tutorial Tekla Structures 12.0 includes a New Features Tutorial, which presents features released in Tekla Structures 11.1, 11.2, 11.3 and 12.0. Each feature contains a description with pictures. Some features also include interactive video lessons that show you how to use the new feature. To access the New Features Tutorial, click Help > Learning Center > New Features Tutorial.

Performance improvements The following now work faster and use less memory: • •

Array of objects (29) component Associative drawings containing objects created with Array of objects (29).

Rollover highlight The rollover highlight makes it easier to select objects, by highlighting each part in yellow as the pointer moves over it. To switch this feature on, click Setup > Rollover highlight.

To switch off the rollover highlight, click Setup and deselect Rollover highlight..You can also use the keyboard shortcut H to turn the rollover highlight on or off.

Log file •

The message panel now displays also the time.


73

•

When you use the Tools > Show log file command to display the log file, Tekla Structures now scrolls to the end of the file automatically.

Managing views Selecting views

74

Selecting visible and named views is now easier in Tekla Structures 12.0. The arrow buttons you use to open and close views in the Views dialog box are now only active when you have selected a view.


Creating views

When you create a view using Views > Create view > Grid views, the grid is now selected automatically if there is only one grid in the view. If there are several grids, Tekla Structures prompts you to select a view:


75

Bringing a view on top

Now when you select a view in the Visible views list in the Views dialog box, the selected view moves to the top. If you have selected multiple views, all selected views will be moved up, with the first one on the list on top. Also, when you select a view in the model, it is automatically selected in the Visible views list.

Navigating in the model Navigating in the model is smoother when you are for example rotating a large model, because Tekla Structures now draws the model first in wire frame as you are moving the model.

Re-displaying warning messages Tekla Structures displays warning messages when necessary, for example when you are about to copy or move objects outside the work area. To prevent Tekla Structures from displaying the warning messages again, select the Do not show this message again checkbox.

To re-display the warning messages, press Shift when the warning message should appear, for example when you are copying or moving objects outside the work area, and Tekla Structures displays the warning message again.

76


2.2

Modeling

Nested assemblies Description

You can now add sub-assemblies and parts to already existing assemblies. A sub-assembly is an assembly that is added to another assembly to form a hierarchical assembly. We use the term nested assemblies to describe this type of assembly. Using nested assemblies is useful when you are modeling split trusses, brackets, railings or pipe racks, for example. A sub-assembly is treated in the same way as an assembly in Tekla Structures: •

It gets its own assembly mark

•

It appears in lists of materials in templates and reports.

You can create a separate assembly drawing of a sub-assembly. For more information, see Nested assemblies in drawings (p. 97).


77

Example of a nested assembly:

Selecting assemblies

Activate the Select assemblies switch on the Select toolbar so that you can select any level of a nested assembly, from the highest, through the subassemblies, down to single parts and bolts. The level of the assembly you have selected is displayed on the status bar. With this switch active, each assembly is highlighted as you move the pointer over it. To move to a specific level in the assembly, with it highlighted, press Shift and scroll the mouse wheel.

78


To be able to select objects in assemblies, activate the Select objects in assemblies

switch on the Select toolbar.

For more information on how to select assemblies and cast-units, see How to select objects in the Modeling manual.


79

Assembly or cast unit properties

80

To view the properties of an assembly or cast-unit, select it, right click and select Properties... from the pop-up menu.


You can also define user-defined attribute values for assemblies and cast units in the same dialog box. Modifying assemblies

The right-click pop-up menu also includes several new options, which you can use to modify assemblies:


81

These options are also on the main menu, under Detailing > Assembly or Cast unit. You can modify assemblies by: • • • •

Adding objects to assemblies Removing objects from assemblies Exploding assemblies Changing the assembly or cast-unit main part

You can combine assemblies in the following ways: • • •

Add and connect parts as secondary parts to an existing assembly Add and connect assemblies as sub-assemblies to an existing assembly Join existing assemblies together without adding any loose parts

For more information on the different commands to use when working with assemblies and cast-units, see Cast units and assemblies. Numbering of nested assemblies

82

Sub-assemblies are numbered in same way as assemblies. Define the prefix, start number and name for the cast unit or assembly in the cast unit or assembly properties dialog box.


Filter

In Tekla Structures 12.0 it is not yet possible to view or select filter by assembly user-defined attributes or by nested assemblies. User-defined attributes

For information about defining user-defined attributes for assemblies, see Userdefined attributes.

Grid line labels always visible Grid labels are now always visible when the grid lines are visible. This allows you to zoom in and still know where you are in the model.


83

To modify the font used in grid labels, use the variables XS_DEFAULT_FONT and XS_DEFAULT_FONT_SIZE in Tools > Advanced options > Model view. You can now use special characters, such as umlauts, accents, and circumflexes, as well as combined characters, such as e acute, in grid labels.

Create, select, and modify single grid lines In addition to creating entire grids, you can now create single grid lines, and select, modify, copy, and move individual gridlines. Gridlines now also have handles. Creating single grid lines

84

To create a single grid line: 1.

Go to Points > Grid line or click the Create grid line

2.

Select the grid.

3.

Pick the first position for the grid line.

4.

Pick the second position for the grid line.


icon.

Grid and grid line properties

Define the properties of the grid line in the Grid line properties dialog box. For more information, see Grid properties in the Modeling manual. If there are skewed grid lines in the model, setting the grid properties back to the original settings is not possible.

Library and parametric profiles are not in separate lists any more, but they are displayed in the same tree structure.

•

Only the relevant profiles for a concrete object are displayed on the Select profile dialog box.

For more information on selecting a profile and defining the material of profiles, see Profile in the Modeling manual.


89

Points not created automatically at ends of parts Tekla Structures no longer automatically creates points at the ends of parts. This uses less memory and reduces processing time. It also means that you do not have to redraw the view as often. If you need a point at the end of a part, you can still create it manually. For more information, see Creating points in the Online help.

You can use part handles and snapping to create and move parts. See the following examples. Select handles

90

To select the handles of a part: 1.

Select the part.

2.

Hold down the Alt key and drag the pointer from left to right to select the part. Tekla Structures displays the handles of the part. The handle at the end that was the first point picked to create the part is yellow and the handle at the other end is magenta.

Miscellaneous Numbering •

94

When you use the Clear numbers command, Tekla Structures now displays a message after numbers have been cleared.


Views •

If you try to open more than nine views, Tekla Structures now displays a warning message.

•

Curved parts with profiles that had small values for size were displayed as straight lines in rendered views. This has been fixed.

Surface treatment •

The Select button next to the Material option in Surface treatment properties dialog box is now grayed out when it is not possible to select a material.

Lotting •

When you used the Lotting dialog box to create lots, Tekla Structures displayed weight in kilograms, regardless of the unit set in Tools > Units and decimals dialog box. This has been fixed.

Sketching •

Opening and closing the sketch editor sometimes took a long time in large models. This has been fixed.

Numeric snapping You can now start entering the coordinates in the Enter a numeric location dialog box by pressing the decimal key on the numeric pad first.

2.3

Drawings

Saving and freezing associative drawings When you have frozen a drawing in Tekla Structures 12.0, the changes that you make to associative objects afterwards in the model are will no longer appear in the drawing. When you change a drawing and then save it, Tekla Structures asks you whether you want to keep the changes. To prevent the drawing from being updated automatically, select the Disable automatic updating checkbox:

You can still open a general arrangement drawing, unfreeze it, and then re-open it to automatically update the drawing with recent changes. To re-enable automatic updating in a frozen drawing: 1.


2.

Select the drawing.

3.

Right-click and select Freeze > Off from the popup menu.

Previously when you updated an assembly, single-part or cast unit drawing without freezing the drawing, the drawing was re-created. Now the drawing is no longer re-created. This means that you must know whether the changes should be shown when you are updating the drawing. To recreate the drawing:

Highlight changes in associative dimensions (p. 108) in the Release notes.


Nested assemblies in drawings You can create assembly drawings of sub-assemblies. Creating sub-assemblies in the model allows you to produce less complicated drawings, which are easier to read and to understand. This reduces the risk of errors in the shop.

This assembly drawing of a truss is complicated and hard to read.

Marks

This assembly drawing of part of the same truss was created using a subassembly. It is much easier to read.

You can define the visibility, content, and appearance of marks for sub-assemblies in assembly drawings. You can also use part marks to display the assembly hierarchy in general arrangement drawings. For more information, see Mark content in the Drawing manual. You can now specify the part mark properties for the main and secondary parts of sub-assemblies in cast unit drawings. To do this: 1.

In the Drawing Editor, go to Properties > Drawing...

2.

Click Part mark... Release Notes Tekla Structures 12.0 Precast Concrete Detailing

97

3.

On the Content tab, select Sub-assembly main part or Sub-assembly secondary part depending on the part mark properties you want to define.

4.

Select the elements to be contained in the part mark.

5.


Bolts and welds

You can define the visiblity of bolts and welds separately for sub-assemblies in the Bolt properties and Weld properties dialog box.

Dimensioning

You can also define the dimensioning properties for sub-assemblies in assembly drawings. For more information, see Dimensioning nested assemblies in the Drawing manual.

Sub-assemblies in templates and reports

With Tekla Structures you can produce templates and reports that show the hierarchical structure of nested assemblies. For more information, see Producing reports on nested assemblies.

Anchor bolt plan An anchor bolt plan is a type of general arrangement drawing that displays the the layout of anchor bolts for a structure.

98


You can automatically create anchor bolt plans in Tekla Structures 12.0. For more information, see Creating anchor bolt plans in the Drawing manual. You can create both enlarged views and detail views in anchor bolt plans. Tekla Structures groups together identical detail views, so that they only appear once in a drawing. If detail views are not included in a drawing, Tekla Structures displays bolt sizes in the enlarged view.

Display large dimension values more clearly You can now use different number formats for dimensions to make large dimensions easier to read in shop and erection drawings. For example you could format 15432 to appear as 15,432 or 15 432. To do this, select the Use grouping checkbox in the Dimension properties dialog box and select a format.


99

Use the variables XS_DIMENSION_DIGIT_GROUPING_CHARACTER to define the separator and XS_DIMENSION_DIGIT_GROUPING_COUNT to define the number format (in Tools > Advanced options > Dimensioning: general).

100


Improvements in level marks The General tab in the Level mark properties dialog box now includes fields that enable you to define the appearance of level marks:

For information, see Create > Level mark in the online help.


101

Define elevation level You now have the option to define the elevation level in general arrangement drawings and in drawing views also according to the view plane. The datum point for general arrangement drawings is set automatically when creating floor plan views. This saves your time and avoids errors during drawing creation. To define the datum level: 1.

Go to Properties > Drawing...

2.

Click View... to display the view properties dialog box.

3.

In the Attributes tab, do one of the following: •

•

To set a specified datum level, select Specified in the Datum point for elevations field. Then enter a specific value in the Datum level field. To set the datum level according to the view plane, select View plane in the Datum point for elevations field.

Create plate side marks on dimension leader lines You can now create plate side marks on dimension leader lines. Plate side marks indicate whether the dimension point is to the face or center of, for example, a plate, web or flange. This is particularly useful: • •

In complex drawings In large-scale drawings, where it can be difficult to see which part a leader line is pointing to.

To create plate side marks:

102

1.

Click Properties > Dimension... to open the Dimension properties dialog box.

2.

In the Plate side marks section of the Marks tab, set Type to Specified.

3.

Define the properties of the plate side marks if required.


For more information, see Marks in the Drawing manual.

Improvements in section symbols New options in the Section symbol properties dialog box allow you to define arrow head size, arrow length, and the distance between the symbol and the section:


103

Define the appearance of the arrow head symbol You can now also define the appearance of the arrow head symbol in the Tools > Advanced options > Drawing properties dialog box using the following variables: •

XS_SECTION_SYMBOL_LEFT_ARROW_SYMBOL Modify the value for a different appearance, for example sections@0.

•

XS_SECTION_SYMBOL_RIGHT_ARROW_SYMBOL Modify the value for a different appearance, for example sections@1.

If you do not set these variables, Tekla Structures uses the traditional style arrow head symbol in the drawings.

In the example above, the variables XS_SECTION_SYMBOL_LEFT_ARROW_SYMBOL and XS_SECTION_SYMBOL_RIGHT_ARROW_SYMBOL have been set to sections@2. This section view symbol includes the location of the section view. If the arrow length is equal to zero, Tekla Structures places the text in the middle of the arrow symbol. Otherwise Tekla Structures places the text along the cut line. 104


Aligning section symbols The variable XS_ALIGN_CUT_SYMBOL_BY_VERTICAL_LINE in the Tools > Advanced options > Drawing properties dialog box only works on when you open drawings created with Tekla Structures 11.3 or older in Tekla Structures 12.0. Set the variable to TRUE, to position the cut symbol on the vertical line. Leave the variable blank to offset the symbol from the vertical line by the size of the arrow multiplied by 1.25.

Here the variable is set to TRUE. Use this option to indicate the exact location of the section view.

Here the variable has been left blank. This is useful when the direction is more important than the location.

The variable XS_ALIGN_CUT_SYMBOL_BY_VERTICAL_LINE is effective now only when you are converting a drawing created with Tekla Structures 11.3 or older into Tekla Structures 12.0 (or greater). You no longer have to restart Tekla Structures to activate changes to this variable.


105

Group identical objects on the same dimension line You can now group identical parts, bolts, components, and cuts or shapes on the same dimension line. You can choose to automatically create dimension line tags, or to define the contents of tags manually. To group identical objects on one dimension line: 1.

In the drawing, right-click and select Properties... from the pop-up menu to open the drawing properties dialog box.

2.

Click Dimensioning... to open the dimensioning properties dialog box. Go to the Dimension grouping tab. You have the following options: •

Activate dimension grouping: Select which objects you want to

group. • •

Grouping properties: Indicate the elements that must be identical. Automatic tagging: Indicate the information to include in dimen-

sion line tags that are created automatically.

106


The dimension line tag indicates the quantity of objects included in the dimension line. To define the symbol that is displayed between the quantity and the automatic tag text, use the variable XS_DIMENSION_GROUPING_COUNT_SEPARATOR in Tools > Advanced options > Dimensioning: general. The default value is x. To define what information to include in a dimension line tag: 1.

Double-click the dimension line whose tag you want to modify.

2.

In the Dimension properties dialog box, go to the Marks tab.

3.

In Tags, replace the << Automatic >> value with the required text.

4.

Click Modify.


107

Highlight changes in associative dimensions To have Tekla Structures highlight the dimension text that has been changed and dimension points that have been moved when you update associative drawings, set the variable XS_HIGHLIGHT_ASSOCIATIVE_DIMENSION_CHANGES to TRUE in Tools > Advanced options > Dimensioning: general.

108


For more information, see Highlight changes in associative dimensions in the Drawing manual. This feature is not yet available for reinforcing bar marks in Tekla Structures 12.0.

Miscellaneous New part mark leader line type There is a new part mark leader line type, which allows you to align a part mark in the center of the face of a part.


109

Dimensioning •

Embedded objects are now dimensioned correctly by the reference points of the object.

Dimensions •

110

When you use the By reference point option in the Dimensioning properties dialog box, dimensions are now also associative to the middle points of objects.


•

Occasionally adding or removing dimension points removed the whole dimension. This has been fixed.

•

The RD symbol was sometimes omitted from running dimensions. This has been fixed.

•

When you create a dimension with three or more points using the Create > Dimension > Free command and end the command on the same point as the previous dimension, the dimensions are now on the same line.

Reinforcing bar marks •

Merged reinforcing bar marks no longer move when you update a

drawing.

Drawing views •

Drawing views no longer overlap templates in assembly drawings.

•

To rollback the Copy > Translate and Move > Translate command to work as it did in Tekla Structures 11.1 and earlier, set the variable XS_DRAWING_NO_SCALING_FOR_COPIED_OR_MOVED_OBJECTS to TRUE. With this variable set, when you copy or move drawing objects from one drawing view to another, they change size according to the scale of the view.

Updating drawings •

In some occasions Tekla Structures did not add the P flag to a drawing in the drawing list when a cast unit had been changed. (The P flag indicated that parts have been changed.) This has been fixed.

Associativity •

Now associative symbols are also created correctly for level marks.

•

When you changed the profile of a part, the hatch pattern did not always adjust to fit the shape of the new profile. This has been fixed.

•

The y coordinate for assembly overall dimension was sometimes calculated incorrectly which caused associativity not to work. This has been fixed.

•

Associativity works now correctly also when the start and end point of a reference line are in the same location.


111

Intelligent cloning •

Sometimes part marks in single-part drawings were incorrect when you cloned single-part drawings and the variable XS_INTELLIGENT_CLONING_ALLOWED was set to TRUE in Tools > Advanced options > Drawing properties. This has been fixed.

Plotting and printing •

You can now define plot origin offset separately for each plotter in the Plotter catalog dialog box.

The new options replace the variables XS_PLOT_ORIGIN_MOVE_X and XS_PLOT_ORIGIN_MOVE_Y. However, setting the variables in Tools > Advanced options > Plotting will override the settings in the Plotter catalog dialog box. •

Using the variables XS_PLOT_ORIGIN_MOVE_X and XS_PLOT_ORIGIN_MOVE_Y also affected the scale of the plot. This has been fixed.

Part marks Merged part marks are now placed correctly when you change the part mark

leader line type. 112


2.4

Import and export

Miscellaneous Location of the origin in DXF and DWG drawings In Tekla Structures 12.0, when a view on a Tekla Structures drawing is moved the origin for the Xref is calculated differently than before. This makes sharing Tekla Structures drawings much easier: you no longer need to adjust the origin when you export to DWG or DXF. In previous versions you sometimes had to adjust the origin when the view had been moved during the modeling process.

Web Viewer •

If you try to publish a model as a web page with Web Viewer using the Selected parts option in Publish as Web page dialog box without selecting any parts, Tekla Structures displays a warning message does not publish the model.

DSTV •

The DSTV file header was not correct when you used the variable XS_USE_NEW_PLATE_DESIGNATION. This has been fixed.


113

2.5

Custom components

Define and create connections for custom parts You can now define a custom connection, seam or detail so that when you use component in a model, you can pick custom parts as the main and/or secondary parts. You do not have to pick each part within the component. This is useful when modeling window details in a multi-layer panel when the panel is a custom part, for example. To define a custom connection, detail or seam for custom parts, use the custom component wizard and pick the custom parts as main or secondary parts. For more information on defining custom components, see Defining custom components in the online help. When you are using the custom connection, Tekla Structures accepts only custom parts as input parts if you have defined the connection with a custom part as an input part. Use the Custom component editor to edit the properties of custom parts. For more information, see Editing custom components in the online help.

Miscellaneous Improvements in the usability of custom components •

Now you only have to click the Modify button once in any custom component dialog box to apply changes. In previous versions, you sometimes had to click Modify repeatedly if a component had many dependencies. To define how many loops Tekla Structures makes to solve dependencies in custom components, use the variable XS_CYCLIC_SOLVER_MAX_LOOPS in Tools > Advanced options > Modeling properties. The default is 2.

•

114

When a custom component is not working correctly and the problem is with the equations, Tekla Structures now displays error messages in the log file that help you recognize the problem source. To see the log file, click Tools > Display log file > Log file...


Fixes •

When you selected a custom seam, its handles were not displayed. This has been fixed.

•

When you selected a nested custom detail, the handles of the custom detail were not displayed. This has been fixed.

•

The Variables dialog box in the Custom component editor includes a new value type, Factor. This is a decimal value without type. You can set the number of decimals for the value type in Setup > Units and decimals dialog box.

•

Now when you create custom components, the custom component objects get the current phase number.

•

Occasionally, adding a custom component in a skewed position generated an application error. This has been fixed.

•

You can now automatically import a set of custom components and sketches when you create a model. To do this, edit the variable XS_UEL_IMPORT_FOLDER in the Tekla Structures batch file to point to the folder that contains the custom components and sketches.

•

Now when you reopen the Variables dialog box, all the equations are shown even if the result of the equation cannot be calculated.


115

•

If the reference points you picked for a custom part were not at the center of the bounding box, the custom part was not positioned correctly. Now when you define a custom part, its coordinate system is in the center of the bounding box. Offsets are calculated from the center of the bounding box. When you edit a custom part created in an earlier version of Tekla Structures, Tekla Structures asks if you want to use this new method of positioning custom parts. If you do, you will also need to open any nested custom components in the custom part and select to use the new method.

Miscellaneous Fixes

122

•

When you are using the Analysis tab in the dialog box of a component to define the analysis profile settings, you can now access the different options even when you have selected No in Use analysis restraints.

•

You can now use multiplication in the values for Buckling length or Length factor for Buckling options in the Design tab of the part properties dialog box.

•

Area load was not distributed correctly for beams also with varying pressure and in some geometric circumstances. This has been fixed.

•

If the model changes after you use the Optimize command, Tekla Structures now marks the analysis results correctly as not up to date.

•

You can now create a simpler analysis model of slabs and panels, where cuts and holes are not considered. To do this, select Yes in the option Simple plate on the Analysis tab of the attributes dialog box.


•

When you create an analysis model of slabs and panels, you can now define offsets for individual vertices of the slabs and panels. The offsets are defined as user-defined attributes on the Analysis offsets tab in the attributes dialog box.

After you have run the analysis or created an analysis model, use the Inquire > Object command to query the vertices. The vertex indices and their coordinates are listed in the Inquire object dialog box. To define the offset for an individual vertex, enter the offset distances as X Y Z (in current length units, values separated by spaces) in the appropriate field, according to the index of the vertex.
