Defect number Development area Description
TSAC-2852 Concrete components Layout tools: The UDA files floorlayout.objects.inp and WallLayout.Udas.dat UDA files are now correctly read from the firm, project, and model folders.

TSAC-3516 Concrete components Mesh bars: The bars now always have at least the minimum length set in the Mesh bars dialog box.
TSAC-3556 Concrete components Embedded anchors (8): Previously, only concrete parts have been taken into calculations when using the Assembly without steel parts option on the Placement tab. This has now been fixed and miscellaneous parts are also considered.
TSAC-3571 Concrete components Rectangular column reinforcement (83): Bottom/Top crank geometry offset is now applied properly.
TSAC-3720 Concrete components Two sided seating with dowel (76): The drainage hole is now created properly.
TSAC-3886 Concrete components Wall to wall connection can now be used on beams based on b×h.
TSAC-3416 Steel components Column with stiffeners W (182), Column with stiffeners S (187) and JP floor beam gusset (11): Previously, the component disappeared when the same component was created near to it. This has now been fixed.
TSAC-3512 Steel components Kingspan File transfer (18) was incorrectly removing valid holes in the MultiBeam sections. This has now been fixed.
TSAC-3530 Steel components Gusseted cross (62): The default bolt spacing for angle bolts is now the same both when you enter the number of bolts and when you do not enter the number of bolts.
TSAC-3670 Steel components Working with the Ship ladder (1) component is now must faster than before.
TSAC-3702 Steel components Shear plate simple (146): When the secondary part was already cut before applying the component, incorrect part geometry was used when positioning bolts. This has now been fixed.
TSAC-3795 Steel components Create hole around part (92): Previously, the hole was incorrectly rotated in some cases. This has now been fixed.
TSAC-3837 Steel components Bent plate (151): Previously, stiffeners were not created with the correct length. This has now been fixed.
TSAC-3874 Steel components U.S. Base plate (1047): Previously, when one row or column of bolts was defined, the edge distance of the bolts was incorrect. This has now been fixed.
TSAC-3898 Steel components Wraparound gusset cross (60): Previously, connection plates were not correctly extended to create a slot through the main or secondary parts. This has now been fixed.
TTSD-19302 Import, export, interoperability

You cannot accidentally snap anymore to the reference model extrema bounding box.

TTSD-30846 Import, export, interoperability When you receive a generic error message in Trimble Connector, you can now find further information about the error in an error log file that is generated in the model folder.
TTSD-32036 Import, export, interoperability You can now include pour and pour unit template fields and UDAs in the IFC4 export. Pour template fields and UDAs are set to IfcBuildingElementProxy and pour unit to IfcElementAssembly in Property Set Definitions. UDAs are set with template field setting using USERDEFINED."UDA".
TTSD-32669 Import, export, interoperability The extra slowness of IFC change management has now been removed.
TTSD-32858 Import, export, interoperability Trimble Connector: Previously in Trimble Connector, the Refresh button in the ToDo view did not synchronize data from Trimble Connect. This has now been fixed.
TTSD-33039 Import, export, interoperability Point cloud data handling sometimes failed from 2019 SP3 onwards, and attaching the model to Tekla Structures was not possible. This has now been fixed.
TTSD-33077 Import, export, interoperability The .stp reference model insert speed has been improved.
TTSD-33216 Import, export, interoperability Trimble Connector: You can assign ToDos to all users in the Trimble Connect project properly again.
TTSD-33615 Import, export, interoperability Ifc2x3 export: Export using Organizer hierarchies sometimes created openings to wrong level. This has now been fixed.
TTSD-34022 Import, export, interoperability Tekla Structures now supports Sketchup version 2020.
TTSD-28023 Templates and reports Reports now show secondary part ID's consistently.
TTSD-32425 Templates and reports Creating reports of very large cast units could cause a crash. This has now been fixed.
TSAC-3448 Drawings Improvements in the Drawing 2D Library have been done to prevent multi-user models from crashing.
TSAC-3607 Drawings Rebar group dimensioning: The symbols were placed incorrectly during the plug-in creation. This has now been fixed.
TSAC-3676 Drawings Rebar group dimensioning: Rebar group dimensioning now works correctly for views that are rotated in cast unit drawings.
TTSD-25278 Drawings A new advanced option XS_DRAW_REBAR_SELF_INTERSECTING_LEGS_WITH_OFFSET has been added. When set to TRUE, this advanced option displays rebars in drawings with overlap in all representations. The option filled line already showed the overlap earlier. The default value is FALSE. Note that FALSE has no impact on the filled line representation.
TTSD-2745 Drawings Filter dimensioning is now dimensioning all rebars in a group for rebar groups that are not straight bars.
TTSD-28502 Drawings Adding surface treatment marks manually now works more reliably.
TTSD-30043, TTSD-31893 Drawings In some cases, opening and recess symbols in drawings could cause a crash. This has now been fixed.
TTSD-32338 Drawings In some cases, a file missing from the environment could cause a crash. This has now been fixed.
TTSD-32524 Drawings Curved dimensions in drawings can now be drawn with short extension lines. Earlier, the Short extension line setting in dimension properties did not work for curved dimensions.
TTSD-32762 Drawings Korean language characters in dimension tags were not displayed correctly. This has now been fixed. The fix can be taken into use by adding the advanced option XS_ENABLE_DIMENSION_TAG_CHARACTER_SET_FIX=TRUE in an .ini file, for example, user.ini. Unfortunately, when the fix is taken into use, the tag mark content Size is displayed incorrectly (?00*800? instead of (400*800), therefore the default value is FALSE.
TTSD-33730 Drawings UDAs were not loaded to the drawing properties dialog boxes if the User-defined attributes section in the properties dialog box had not been opened first. This has now been fixed.
TTSD-33788, TTSD-33790 Drawings Manually created detail marks can now be:
- moved using Shift+drag
- copied using Ctrl+drag

Note that the detail marks can only be moved or copied within a view. When moved beyond the view frame, the view frame will adjust so that the detail mark will always be within it.
TTSD-30977 Tekla Model Sharing In Tekla Model Sharing, importing or exporting parametric user-defined profiles in the .lis format is no longer possible without a subtype. This will prevent creating broken or incorrect files.
TTSD-32744 Tekla Model Sharing Previously, changes made in the rebar catalog were not included in write-out packets, if the changed rebars were only used in rebar sets in the shared model. This has now been fixed, so that all rebar catalog changes are included in write-out packets.
TTSD-34133 Tekla Model Sharing When a shared model is read in, and Tekla Structures sets the rebar numbering in drawings as not up to date because of numbering conflicts, the part numbering and the cast unit numbering are now also set as not up to date.
TTSD-13154 Reinforcement The visualization of curved and circular reinforcing bars containing hooks has been improved where previously the hook bending was not correctly represented.
TTSD-15678 Reinforcement The threading visualization used in rebar sets is now also available for reinforcing bar groups and single reinforcing bars.
TTSD-29759 Reinforcement When attaching rebar set bars to concrete parts, Tekla Structures now uses the center of bars instead of the center of gravity to determine to which parts the bars are attached. Previously, using the center of gravity could cause rebar set bars to be attached to incorrect parts as the center of gravity could locate outside the bars. This happened to L-shaped bars, for example.
TTSD-31061 Reinforcement Previously, rebar set adaptivity did not work correctly when magnetic grid planes were used in the model. This has now been fixed.
TTSD-31463 Reinforcement Previously, all rebar sets were modified after you set the work plane. This happened when you deleted a rebar set, undid the delete command, and then updated the window. This has now been fixed.
TTSD-32199 Reinforcement Previously, when you created a concrete part with a round part cut, a rebar set bar that intersected the edge of the cut was not correctly attached to the concrete part. This has now been fixed.
TTSD-32834 Reinforcement Previously, if a rebar set had a rebar that was assigned to two different groups, rebar set numbering was not kept when reopening the model. Now you can check and repair these duplicate assignments using the Diagnose & repair command.
TTSD-7959, TTSD-31577 Reinforcement Split rebar groups are now mirrored correctly.
TTSD-8028, TTSD-8098 Reinforcement Tapered (or tapered ridge, tapered curved) rebar groups with excess exact spacing values are now mirrored correctly.
TTSD-8097 Reinforcement Previously, when direct modification was used to create exact spacings and a zero/negative end offset for a rebar group, the rebar group was not mirrored correctly. This has now been fixed.
TTSD-16351 Modeling Previously, pour breaks did not work in some cases when the parts forming the pour were very slightly tilted. This has now been fixed.
TTSD-30036 Modeling Shapes that are inserted to a model are now copied to the model folder.
TTSD-30827 Modeling The Move special > Mirror and Copy special > Mirror commands now work correctly for radial grids.
TTSD-31590 Modeling Previously, when you created a stand-alone bent plate so that the top arc start point was the same as the top arc center point, Tekla Structures stopped working. This has now been fixed.
TTSD-32449 Modeling Previously, polycurve geometry was removed when repairing the database if the XS_DELETE_UNNECESSARY_INT_ARRAYS advanced option was set to TRUE. This lead to corrupted polycurve geometry that caused Tekla Structures to crash. This has now been fixed. Polycurve has been added to the Diagnose model command so that it removes the corrupted geometry. In this situation you need to recreate the polycurve.
TTSD-32783 Modeling Previously, creating a view from a radial grid when the view was different from the default XY plane view produced incorrect results. Now this has been fixed.
TTSD-32919 Modeling Previously, Tekla Structures could crash when creating a model on a file server. This has now been fixed.
TTSD-33288 Modeling Previously, pour breaks did not work in some cases where the parts forming the pour overlapped and shared a face. This has now been fixed.
TTSD-33373 Modeling The contents of an assembly are now shown correctly when using the Assembly > Show assembly command.
TTSD-33390 Modeling The solid errors found in the currently open model are now shown in the report that opens when you use the Diagnose & repair > Diagnose model command on the File menu.
TTSD-33487 Modeling Tekla Structures model background colors are now correctly set back to the default colors when leaving the background color advanced options values empty.
TTSD-34006 Modeling Previously, the sketch editor could crash in certain situations. This has now been fixed.
TTSD-34291 Modeling The notifications.xml file is now again saved in the <user>\AppData\Local\ folder.
TTSD-34345 Modeling Previously, Tekla Structures could crash in some cases related to polygon welds. This has now been fixed.
TTSD-5272 Modeling Pour breaks now work more reliably in cases where the parts forming a pour object partially touch each other.
TTSD-33171 Analysis and design When you modified a property in the Analysis model properties dialog box and clicked OK, and then used the Undo command, the modified property still stayed in the Analysis model properties dialog box. This has now been fixed.
TTSD-32726 Tools and components In custom components, bitmap (.bmp) images from the model folder are now correctly shown in the component dialog box.
TTSD-34140 Tools and components Applications & components catalog: Importing a .uel file immediately after creating a new model could result in the automatically imported catalog information (for example, thumbnails) being lost. This has now been fixed.
TTSD-33507 User interface Previously, changing very long rebar bends to straight bars in large rebar sets could cause Tekla Structures to stop working. This has now been fixed.
TSAC-3605 Import, export, interoperability (steel) NC files: The quantity of parts in the NC file was incorrect when hardstamp with assembly position was used and the advanced option XS_SECONDARY_PART_HARDSTAMP was set to TRUE. This has now been fixed.
TSAC-3481 Import, export, interoperability (concrete) BVBS Export: Previously, export was prevented if the intended output folder could not be found. Now the defined folder path is created.
TSAC-3517 Import, export, interoperability (concrete) Export Unitechnik (79): You can now specify Output file structure as Single layer, 1 slabdate, n steelmats on the Main tab. This new option only exports the main part of the cast unit as SLABDATE, and meshes and embeds from whole cast unit in one row in export X axis direction with a 1 mm gap between them.
TSAC-3574 Import, export, interoperability (concrete) BVBS Export: When the Drawing name source property cannot be found, a message is now added to the export log.
TSAC-3682 Import, export, interoperability (concrete) Export Unitechnik (79): The visualization in Tekla Structures model for the scanned geometry of the embeds is now drawn in the respective double wall shell.
TSAC-3684 Import, export, interoperability (concrete) Export EliPlan file (68): You can now specify the accessory code for standard embeds such as steel parts on the Data content tab. This will be the code written to each embed in the #Plotter (if applicable) and #Materials blocks, and the chosen option should be used as a base for further data conversion mapping. The default option is NAME|PROFILE-LENGTH|MATERIALGRADE.
TSAC-3736 Import, export, interoperability (concrete) BVBS Export: For the file name option [Assembly template], any assembly or main part USERDEFINED property can now be used even if they are not included in any of the contentattributes.lst files.
TSAC-3791 Import, export, interoperability (concrete) Export EliPlan file (68): Rectangular openings at the edge of hollow core slabs with certain profiles were occasionally exported as a thin line, instead of box-shape. This has now been fixed.
TSAC-3864 Import, export, interoperability (concrete) Export Unitechnik (79): It is now possible to set the installation height of braced girders to zero ('0') using the new option Without concrete cover on the Reinforcement tab.
TSAC-3941 Import, export, interoperability (concrete) Export Unitechnik (79): The braced girder diagonal wire rebar handles at arcing points affected the double wall total and production thicknesses when bent rebars were excluded. This has been fixed. Also a new option Double wall width has been added on the SLABDATE block data specification tab for the settings Total thickness and Production thickness. This option exports the template report property CAST_UNIT.WIDTH.
