2020 SP3: New features and improvements


Previously, when you selected several drawings in Document manager and changed object level settings for the drawings, Tekla Structures showed a confirmation dialog box for each drawing separately. Now updating is much faster if you have selected many drawings, as Tekla Structures only shows the dialog box once, and you can confirm the change for all drawings at once.
TTSD-37339


You can now easily synchronize your drawing sizes with the paper sizes that are used in printing. This way, you can ensure that the drawing sizes that you use for your drawing layouts are also available for printing. Note that the drawing sizes and paper sizes are only synchronized in the current model
To synchronize the drawing sizes and paper sizes:
- When you save a drawing layout, select the Synchronize listed sizes with paper sizes for printing check box.
If Tekla Structures detects new drawing sizes, a copy of the Papersizesfordrawings.dat file is created in the \attributes folder under the model folder
TTSD-36102


The IFC2x3 export datetime property now provides a correct not set value "$" if a value is not found. For example, this occurs for the DRAWING.REVISION.LAST_DATE_CREATE property if the drawing does not have a revision.
TTSD-34004


You can now use new keyboard shortcuts to modify the part position of beams, polybeams, contour plates, and slabs, instead of using the Position options in the property pane or on the contextual toolbar. The keyboard shortcuts work for both native Tekla Structures parts as well as for analysis parts.
The new part position shortcuts are available also on Quick Launch.
The part position is relative to the part reference line between the part handles, and the part position changes according to the used keyboard shortcut option.


If the new keyboard shortcuts are not working, restore the default keyboard shortcuts to enable the new ones. If you have defined your own keyboard shortcuts and want to keep them, you need to map these new keyboard shortcuts manually.
TTSD-38511
TTSD-34098


When modifying rebar sets, you can now change the direction of splitters, modifiers, and guidelines by using the new Swap ends button on the contextual toolbar.
TTSD-37208


You can now use SUB_ID_WITH_LETTERS and SUB_ID_WITH_LETTERS_LAST as template attributes when you report tapered bar groups created by rebar sets.
TTSD-20561
Fixed defects in version 2020 SP3


Concrete foundation (1030) has been improved as follows:
- On the Picture tab, you can now define an offset for the injection tube from the bottom of the column. Also, the sloping injection hose is now properly fitted to the column edge.


- On the Parts tab, there is a new option, Poly-profile (as sub-assembly), for Type of reinforcing bars. This new option creates a poly-profile as a sub-assembly to the foundation part.
................................................................................
Reinforcement mesh array (91): Mesh creation did not work on slabs that contained a great number of notches. This has now been fixed.
................................................................................
Wall layout connector has been changed so that there is no crash when getting values and layers from a corrupted Wall layout component.
Note that the Wall layout connector component is not adjusted or updated when one of the connected Wall layouts is moved. For this you still need to delete the corrupted connector and add a new one.
................................................................................
Concrete console (110) and Concrete beam-beam (112): Previously, when modifying the components with changes that did not affect numbering, the numbering was changed to not up to date. This has now been fixed.
................................................................................
Reinforced concrete stair (95) : You can now define different covers for the floor-level dummy profiles for the top/middle/bottom steps as well as the vertical cover thickness.
Additionally, you can now define Position in depth for the created profiles.
................................................................................
Hollowcore reinforcement strands (60) now reads more values of the defined grid from external files. This allows you to add a bigger grid for the strands. This has been improved on the external files side only, and not in the dialog box, because of length limitations.
................................................................................
Rectangular column reinforcement (83): You can now create intermediate links as one stirrup group with the Create as one group option on the Intermediate links tab.
................................................................................
U.S. Base plate (1047): Previously, one hole below the washer plates was created with an incorrect diameter. This has now been fixed.
................................................................................
Base plate (1004): Previously, the galvanizing holes were not created in case anchor rods were used instead of bolts. This has now been fixed.
................................................................................
Haunch (40): Previously, when two-sided haunches were created, some welds were missing for the second haunch. This has now been fixed, and all welds are created correctly.
................................................................................
Seat type 9 (73): Previously, setting the number of bolts to 0 for the vertical or horizontal direction caused Tekla Structures to crash. This has now been fixed.
................................................................................
Base plate (1004), Web stiffened base plate (1016): Previously, the leveling plate did not follow the position of the additional beam. This has now been fixed.
................................................................................
Railings (S77): It is now possible to use custom components as the connection between the stanchions and the top, middle, and bottom rails.
................................................................................
Railings (S77): Previously, using the connection to connect middle rails to stanchions created the connection only for one rail. This has now been fixed and both rails are now connected to the stanchions as defined on the Middle rails tab.
................................................................................
Joist to column, type 1 (161): Previously, defining the cut back distance of the bottom chord caused the component to crash. This has now been fixed.
................................................................................
Shear plate (103): Previously, bolt edge distances were not correct. This has now been fixed.
................................................................................
Column with stiffeners W (182): Previously, the weld properties in the component did not match the values set in the dialog box. This has now been fixed.
................................................................................
Extend full depth tab (82): Previously, bolts were created incorrectly in some situations. This has now been fixed.
................................................................................
Two sided end plate (142): Previously, welds number 1 and 5 were also used to weld haunch plates to the secondary parts. This has now been fixed.
................................................................................
Two sided end plate (142): Previously, the welds between the haunch plates and end plates were missing when a secondary part was skewed. This has now been fixed.
................................................................................
Hollow brace wraparound gusset (59), Corner tube gusset (56), Tube gusset (20), Tube crossing (22): You can now define brace bolt edge distances.
................................................................................
Railings (S77): The start and end closures are now fitted to the first and last stanchion.
................................................................................
Reference models: Sometimes imported curved IFC beams appeared with rough segmenting. This has now been fixed.
................................................................................
IFC2x3 export: Welds are now exported with solid colors.
................................................................................
IFC2x3 export: The Tapered curved rebar groups are no longer exported so that the self-intersecting bars are clashing (2D).
................................................................................
Tekla Structures sometimes crashed when you tried to save a multi-user model with the compact view in the Applications and Components catalog . This has now been fixed.
................................................................................
Sometimes inserting a reference model failed because of special characters. Now all characters below 256 are allowed in a reference model file name: both ASCII (0-127) and extended ASCII (128-255).
................................................................................
NC/DSTV: Before, when the diameter of a round cut was less than the maximum diameter for circular cuts to be drilled, these cuts were not exported to DSTV as drilled holes. This has now been fixed.
................................................................................
In addition to the environment folders, graphical templates can be read from the XS_FIRM and XS_PROJECT folders. Previously, the \template folder was excluded from the template file search if it was a subfolder of XS_FIRM or XS_PROJECT. Now, the XS_FIRM\template and XS_PROJECT\template folders are included in the template file search. Drawing templates are searched from all XS_PROJECT and XS_FIRM folders, except for the hard coded folders like Organizer, or hard coded template folder subfolders.
................................................................................
Align to top for a multiline value field sometimes failed when the content of the value field was one-line text. This has now been fixed.
................................................................................
The last line of a multiline ValueField was sometimes cut off when automatic font resize was used. This has now been fixed.
................................................................................
Previously, column headers were not positioned correctly in tables that were filled vertically from top to bottom and aligned to the right. This has now been fixed.
................................................................................
Previously, recreating cloned drawings added non-existing extra drawings to the drawing list in Document manager. This has now been fixed.
................................................................................
When the distance between points in a rebar dimension is very small (for example, when you dimension closely packed rebars), but the set of equal dimensions is combined into a single dimension, the arrow heads at the ends of dimension lines are now correctly placed inside the combined dimension.
................................................................................
When you edited more than two dimension sets or more than two dimension bases that had prefix or postfix values defined, those values were not shown in the properties dialog box. The same applied to two rebar dimension marks when Dimension to was set to Start and end rebars. This has now been fixed.
................................................................................
When you change the value of the XS_BLACK_DRAWING_BACKGROUND advanced option, you no longer need to restart Tekla Structures to activate the new value.
................................................................................
In some cases, adding a graphical object in a drawing caused Tekla Structures and Windows to freeze for several minutes. This has now been fixed.
................................................................................
When you add .dxf and .dwg files to the drawing layout using Layout editor, if the file is located under the model folder, a relative path is used. Otherwise, an absolute file path is used. This simplifies creating drawing layouts for shared models, because folder structure can be different on different computers.
................................................................................
The Rebar command (Add rebar dimension marks) was missing from the ribbon in the drawing mode in the EPM modeller, Partner, Production planner, Steel Detailer and Viewer configurations. This has now been fixed.
................................................................................
Previously, the line thickness was not updated when in black and white mode. This has now been fixed.
................................................................................
Lines that link rebar dimensions are now drawn using drawing coordinates instead of model coordinates. This means that reinforcement marks are placed correctly again.
................................................................................
In Layout editor, table anchoring has been improved so that dragging tables now works more logically.
................................................................................
Arrow placing and direction is now correct for both regular dimensions and rebar dimension marks when Combine equal dimensions is activated, and the distance between each equal dimension is smaller than or equal to the arrow head length.
................................................................................
Previously, layout files were randomly missing from exported drawing files when the layout files were read from XS_FIRM or XS_PROJECT folders. This has now been fixed.
................................................................................
The extension line at the end of rebar dimension marks and the away part of the extension line in rebar dimension marks and in normal dimensions were missing. This has now been fixed
................................................................................
The Rebar number mark property is now correctly updated in rebar dimension marks with subgrouping for rebar sets after the model is updated and renumbered.
................................................................................
NUMBER_IN_DRAWING regarding rebar groups was not updated correctly in an associative note. This got broken in another fix regarding rebar set groups, and has now been fixed.
................................................................................
The mark content for radial curved rebar dimension marks is now correct regardless of which side of the rebar group or rebar set you pick.
Also, when you select curved rebar dimensions, the Subgrouping setting in rebar dimension mark properties is now automatically set to No, and the setting is disabled. This is because curved dimensions consist of only one dimension base.
................................................................................
Dimension associativity rules are now sorted and show more clearly if the rule is associated to a reference point.


................................................................................
Symbol files in the model were not used in printing if the same symbol file was present elsewhere (defined by DXK_SYMBOLPATH). This has now been fixed.
................................................................................
Previously, Tekla Structures could sometimes crash when you moved several drawing views in one go from one drawing to another drawing. This has now been fixed.
................................................................................
Previously, the sort order in Document Manager was reset when you saved a multi-user model. This has now been fixed.
................................................................................
Document manager now has a Delete button for deleting the selected documents, and Next and Previous buttons to open the next and previous drawings.
................................................................................
Previously when you printed drawings to Description files, when a revision was included in a Description file that contained a period (for example, in a date), the revision text was not inserted in the correct location. This has now been fixed.
................................................................................
Rebar pull-out picture and marking: The Rebar pull-out picture and marking application has been improved for rebar sets. Some rebar set shapes were previously not represented, or were represented incorrectly The shapes are now represented correctly.
................................................................................
Previously, some files were not read from project or firm folders if there were semicolons (;) in the folder path. This has now been fixed.
................................................................................
Previously in some situations, pour GUIDs between different Tekla Model Sharing users could go out of sync. Because of this, pour data was corrupted and Tekla Structures could crash during read-in. This has now been fixed.
................................................................................
Previously, excluding a folder from sharing only worked for folders directly under the model folder, not for sub-folders. This has now been fixed.
................................................................................
Previously, there was an error in the property pane if you tried to copy properties from a rebar set to itself. This has now been fixed.
................................................................................
Previously, if you changed the phase of a rebar set in the Phase manager, the numbering status of the rebar set changed to out-of-date. This does not happen anymore.
................................................................................
Previously, rebar set hooks could appear at the wrong angle in drawings. This has now been fixed.
................................................................................
Previously, selecting filters in the Object group - Selection filter dialog box could become very slow when using project or firm folders over network drives, especially when the folders contained many subfolders.
You can now use an advanced option to enable optimized filter selection, which reduces the time to select any filter that has already been selected at least once during the Tekla Structures session. The optimization can be activated by setting the XS_FILTER_DIALOG_USE_CACHED_SEARCH_RESULTS advanced option to value true in an initialization (.ini) file. This advanced option is not shown in the Advanced options dialog box.
Example: Open teklastructures.ini, and add the following line:
set XS_FILTER_DIALOG_USE_CACHED_SEARCH_RESULTS=true
................................................................................
When merging complex parts by using the Added material > Attach to part command, Tekla Structures sometimes crashed. This has now been fixed.
................................................................................
Previously, selecting a concrete part with the Alt key pressed did not select the rebar sets. This has now been fixed.
................................................................................
When creating a spiral beam, the snapping now works correctly.
................................................................................
In the Snapping toolbar, the list for selecting the snap depth (Auto/view plane) now works correctly.
................................................................................
You can now import .lis catalog profiles with a numeric SUB_TYPE value.
................................................................................
Obsolete data is now more efficiently removed from the model database.db1 so that the file size will be smaller.
................................................................................
Previously, you had to change the work plane when creating a construction circle in any other view than a basic global view, for example, in the elevation view. This has now been fixed.
................................................................................
Previously, in some rare cases, Tekla Structures could crash when you moved a custom component and then modified a property in the custom component dialog box. This happened when a bent plate was used in the custom component that was located far away from the origin. This has now been fixed.
................................................................................
Previously, snap highlight sometimes got stuck in the view until the view was redrawn. This has now been fixed.
................................................................................
When importing .tsep files with Tekla Structures extension manager, Tekla Structures shows a message that asks whether you want to delete or keep the original .tsep files. This message has now been improved. The Yes and No buttons have been renamed as Delete and Keep to help you in selecting the appropriate action.
................................................................................
All empty subfolders are now correctly deleted from the \Extensions\To be installed\ folder when the .tsep packages installation is complete. The subfolders left from older installations are also deleted.
................................................................................
Model environment information is now taken from XS_SYSTEM. The folder under \Environments\ is used as the environment name.
................................................................................
Previously, .tsep system logging sometimes conflicted with virus scanners, which could cause issues in extension or environment installations. The .tsep logging has now been changed to make it more robust, and to allow scanning of the log while in use.
................................................................................
Migration Wizard now excludes the environment .tsep files which are installed by the environment installers. This is to avoid the risk of having localization files that are not compatible with the new Tekla Structures version.
................................................................................
Migration Wizard now has a progress bar that shows the progress of the migration process.
................................................................................
Previously, concrete cover attributes for parts did not appear in the custom component browser. This has now been fixed.
................................................................................
Previously, you could not open the dialog box of a .NET component published in the Applications & components catalog. This has now been fixed. .NET components now correctly use their attribute file when inserting the components to the model.
................................................................................
Layout manager: Previously, deleting a layout point in the model and then selecting this point in Layout manager caused an error. This has now been fixed.
................................................................................
The height of the monitor or the number of monitors do not cause issues anymore with the saved Windows registry values for the Width of the snapping toolbar.
................................................................................
Trimble Connect Visualizer: The color and transparency of glass have been updated.
Note that you should not edit the VisualizerMaterials.xml file manually.
................................................................................
Snapping tooltips are now shown correctly in all languages.
................................................................................
In the Applications & components catalog, the search box tooltip text has been improved. The square brackets are now shown correctly as [ ], instead of a rectangle [].
................................................................................
Export EliPLAN file (68): You can use the new Project number and Project name settings on the Data content tab to specify the project number and project name in the exported file, using the set project user-defined attributes or template attributes and user-defined text.
................................................................................
Export EliPLAN file (68): When the product code or accessory code is empty, you are now notified by a message in the log file and in the process console.
................................................................................
BVBS Export: On the Data content tab, in the Position source setting, there is a new option Reinforcement template available.
................................................................................
Export Unitechnik (79): You can now export element quantity in the SLABDATE block using the new setting Export quantity. If the exported sets have multiple cast units, they will have their quantity marked in the SLABDATE reference number field. The export sets are defined by the file name definition or cast unit position. The options are:
No: 000 written in the field (default)
Always 1: 001 written in the field regardless if the files names are unique or not
From selection: If the cast units have identical file names, they will be exported with only 1 file, and the total quantity of the set is written in the field
From total in model: The total quantity of the cast units by position in the model is written in the field
................................................................................
Export Unitechnik (79): Previously, in some cases the second shell of the double wall had an incorrect X axis offset. This has now been fixed.
................................................................................
Export Unitechnik (79): Previously, the exposure class for both shells of a double wall was read from the first shell. This has been fixed, and the exposure class is now read from each of the shells.
................................................................................
Export EliPLAN file (68): It is now possible to export weep holes only at the middle of elements with a length less than the specified length using the option At middle only, length less than on the Descriptionter data tab.
................................................................................
Export EliPLAN file (68): It is now possible to read the erection sequence from a UDA or from a custom property using the Erection sequence option on the Data content tab.
................................................................................
Export EliPLAN file (68): It is now possible to read the erection section from a UDA or from a custom property using the Erection section option on the Data content tab.
................................................................................
Export EliPLAN file (68): Previously, when exporting the element with notches at the start and at the end of the element, the coordinates of embeds inside element were exported incorrectly. This has now been fixed.
................................................................................
Export Unitechnik (78): You can now specify the mesh type using the Mesh type option on the Unitechnik tab in the reinforcement user-defined attributes dialog box.
................................................................................
Export EliPLAN file (68): You can now export the net area of elements using a custom property
................................................................................
Export Unitechnik (79): Previously, the Bottom rebar = type 1 option on the Reinforcement tab was not working correctly for the reinforcement in the second shell of a double wall. This has now been fixed.
................................................................................
Export EliPLAN file (68): You can now specify that the Tag for lifters should be read as the current default value (Default), a user-defined attribute (UDA), or a template attribute (Template), as well as custom properties.
................................................................................
Export EliPLAN file (68): You can now add up to three comments at the start of exported files by selecting comment options in the Comment lists on the Data content tab. The options are No comment, Tekla Structures version, Model name, User name, and User-defined text. The comments are only for viewing the export file and will not be read in to EliPLAN.


Tekla Structures is advanced structural BIM software for creating, combining, managing and sharing multi-material 3D models packed with constructible data. From conceptual planning to fabrication, construction and maintenance, to design, detailing and information management, Tekla models contain all the structural data needed to build and maintain any type of structure.
Tekla Structures 2020 delivers enhancements, improvements and new features that enable efficient workflows for better productivity, increased mobility and collaboration across project teams, including easier modeling of complex shapes with geometry improvements. More specifically, Trimble has enhanced the creation of lofted plates and lofted slabs. For example, in addition to using construction lines, arcs, or circles to create the lofted parts that were possible with the previous release, users can now model complex curved shapes by using polycurve construction objects.
In Tekla Structures 2020, the creation of lofted plates and lofted slabs has been enhanced as well. For example, in addition to using construction lines, arcs or circles to create lofted parts, users can now model complex curved shapes by using polycurve construction objects. Lofted plates in single-part drawings can now be unfolded. With that flat plate, the drawing provides the instructions they need to create a complex shape.
Trimble Connect is now included with Tekla Structures Maintenance! See how to quickly upload models to Trimble Connect using the brand new interface in Tekla Structures 2020.
