Defect number Development area Description
TSAC-4346 Concrete components Reinforcement mesh array (91): Mesh creation did not work on slabs that contained a great number of notches. This has now been fixed.
TSAC-3385, TSAC-4340, TSAC-4341 Concrete components 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.
Concrete foundation 1030 injection tube offset.png
  • 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.
TSAC-4396 Concrete components 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.
TSAC-4405 Concrete components 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.
TSAC-4435 Concrete components 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. 
TSAC-4531 Concrete components Corbel reinforcement (81): The component is now created properly in situations where the corbel is smaller than the column.
TSAC-4583 Concrete components Seating with dowel to flange (77), Two sided seating with dowel to flange (78): The bearing pad no longer collides with the column.
TSAC-4622 Concrete components Previously, Wall layout layer swapper components were removed when repairing the model and/or ignored in shared models. This has now been fixed.
TSAC-3036 Steel components Stiffeners (1034): Previously, the gap between the stiffener and the main part web was incorrectly applied. This has now been fixed.
TSAC-3977 Steel components Cage ladder (S60): You can now define the rotation of the rail bars on the Parameters tab. You can also define the vertical and horizontal offset of bottom supports on the Supports tab.
TSAC-4179 Steel components Two sided end plate (142) & End plate (144): Previously, the horizontal offset of bolts also affected the position of galvanizing holes. This has now been fixed.
TSAC-4273 Steel components Partial stiff end plate (65): Previously, when the bolt spacing was specified asymmetrically, the holes in the shim plates were created incorrectly. This has now been fixed.
TSAC-4306 Steel components Base plate (1042): Previously, when you specified to create anchor rods as custom components and did not define the thickness of the cast plate, the component was not created. This has now been fixed.
TSAC-4307 Steel components 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.
TSAC-4308 Steel components 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.
TSAC-4324 Steel components Welded column with stiffeners (128): Previously, the gaps between the stiffeners and main part flanges were not applied correctly. This has now been fixed.
TSAC-4375 Steel components Extend full depth tab (82): Previously, bolts were created incorrectly in some situations. This has now been fixed.
TSAC-4376 Steel components 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.
TSAC-4398 Steel components Shear plate (103): Previously, bolt edge distances were not correct. This has now been fixed.
TSAC-4399 Steel components 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.
TSAC-4453 Steel components 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.
TSAC-4491 Steel components 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.
TSAC-4501 Steel components 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.
TSAC-970 Steel components Railings (S77): The start and end closures are now fitted to the first and last stanchion.
TSAC-3134 Import, export, interoperability 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.
TSAC-4380 Import, export, interoperability Export Unitechnik (79): Previously, the Tekla Structures version option for the File creator (UT 6.0) setting was not working correctly. This has now been fixed.
TTSD-19700 Import, export, interoperability

The value of the user-defined attribute SDNF_MEMBER_NUMBER is no longer copied with the related part, so the resulting identifier is now unique. Note that it is still important that only one user in the model performs the SDNF export, so that you can prevent two objects from getting the same identifier.

TTSD-34498 Import, export, interoperability IFC2x3 export: You can now export all project properties as property set properties with IFC2x3 export.
TTSD-34846 Import, export, interoperability 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).

TTSD-35611 Import, export, interoperability 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.
TTSD-36623 Import, export, interoperability Objects are now imported from locked reference models when you refresh the reference models, provided that the XS_REFRESH_ALSO_LOCKED_REFERENCE_MODELS advanced option is set to TRUE. In addition, Hole Reservation Manager now updates voids in locked reference models correctly.
TTSD-36914 Import, export, interoperability IFC2x3 export: The Tapered curved rebar groups are no longer exported so that the self-intersecting bars are clashing (2D).
TTSD-36956 Import, export, interoperability IFC reference model assembly selection sometimes selected too much. This has now been fixed.
TTSD-37030 Import, export, interoperability Drawing DWG export: Export rules with rebar set object filtering rules work better now.
TTSD-37037 Import, export, interoperability Trimble Connector no longer consumes a Trimble Connect Business Premium license. Previously, a Trimble Connect Business Premium license was consumed, even though using Trimble Connector does not require this type of a licence. This prevented the use of the same license seat in Trimble Connect, so the user could not access the Trimble Connect features that were available for Business Premium users.
TTSD-37406 Import, export, interoperability You can now convert IFC objects in ELITECAD models to Tekla Structures native objects.
TTSD-37466 Import, export, interoperability IFC2x3 export: Welds are now exported with solid colors.
TPLED-165 Templates and reports Template library now gives more descriptive conversion warning messages that show the component name and template filename.
TPLED-173 Templates and reports Template Editor: Previously, when the row sort type of a template was set to None, the row order could sometimes change. This has now been fixed. 
TPLED-178 Templates and reports

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.

TTSD-34086 Templates and reports Drawing attributes could not be reported through a REBAR row if the row was outputting a rebar set bar. This has now been fixed.
TTSD-36696 Templates and reports Template Editor no longer crashes when you are dragging several lines and cancel by pressing the Esc key.
TTSD-36770 Templates and reports The ROW_IN_PAGE template attribute now works properly again.
TTSD-37026 Templates and reports Columns are now working again in reports.
TTSD-37364 Templates and reports The LOCKED_BY drawing attribute now returns the correct value.
TTSD-20200 Drawings Previously, when you printed drawings to plot files, when a revision was included in a plot file name that contained a period (for example, a date), the revision text was not inserted in the correct location. This has now been fixed.
TTSD-20331 Drawings Printing: Previously, the PaperSizesForDrawings.dat file was not always read from the correct folder. This has now been fixed.
TTSD-21855 Drawings

Document manager has two new buttons at the bottom of the window:

  • Image
    Delete drawing.png
     Delete button for deleting the selected drawings or file documents. Previously, you could only delete selected drawings by selecting Delete in the context menu.
  • Image
    Button Open prev.png
      Open previous drawing and
    Button Open next.png
     Open next drawing buttons for opening the previous or next drawing while a drawing is open. Previously, you could only open previous and next drawings by pressing Ctrl+Page Up or Ctrl+Page Down on the keyboard.
TTSD-24134 Drawings If an assembly contained a spiral beam, and a shape dimension rule was chosen for creating a drawing view, the creation and opening of the drawing took a long time, and the dimensions were incorrect. This can no longer happen, because shape dimensions are no longer created for an assembly containing a spiral beam.
TTSD-27852 Drawings Previously, the sort order in Document Manager was reset when you saved a multi-user model. This has now been fixed.
TTSD-32458 Drawings Previously, Tekla Structures could sometimes crash when you moved several drawing views  at one go from one drawing to another drawing. This has now been fixed.
TTSD-33468 Drawings 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.
TTSD-33595 Drawings

Dimension associativity rules are now sorted and show more clearly if the rule is associated to a reference point.

Associate to reference points.png

TTSD-34615 Drawings Empty rows are no longer shown in the dimension associativity rule list.
TTSD-34642 Drawings

NUMBER_IN_DRAWING was not updated correctly in an associative note due to rebar set bars in the group type 'unknown'. This has now been fixed.

TTSD-36802 Drawings Sometimes you got duplicate marks to parts when adding marks manually through the context menu. This has now been fixed.
TTSD-37023 Drawings Rebar group rebar dimensions could not be moved after their creation. You can now reposition the rebar dimensions as required.
TTSD-37352 Drawings Lines that link rebar dimensions are now drawn using drawing coordinates instead of model coordinates. This means that reinforcement marks are placed correctly again. 
TTSD-37374 Drawings Previously, hatches were not shown for circles in drawings. This has now been fixed.
TTSD-37800 Drawings 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.
TTSD-39027 Drawings Sometimes Tekla Structures froze when you opened a drawing that contained graphical objects (polygons) with hatches. This has now been fixed.
TTSD-39216 Drawings Creating a polyline or a polygon in drawings no longer causes a Tekla Structures application error.
TTSD-36755 Tekla Model Sharing Previously, Tekla Structures occasionally crashed when you converted a multi-user model to a single-user model. This has now been fixed.
TTSD-37935 Tekla Model Sharing Previously, start sharing and write out could sometimes fail if the temporary packet creation file was locked by another application, a virus scanner, for example. This has now been fixed.
TTSD-37993 Tekla Model Sharing Previously, excluding a folder from sharing only worked for folders directly under the model folder, not for sub-folders. This has now been fixed.
TTSD-38820 Tekla Model Sharing Previously, when inviting users to a shared model in the Start sharing dialog box, the email addresses that had capital letters were temporarily shown as duplicated in the list of users until you reopened the dialog box. There were also issues in receiving email invitations to the model. Now this has been fixed.
TTSD-39160 Tekla Model Sharing Previously, downloads were occasionally jammed in the Tekla Model Sharing service when reading in or joining a model. This was most likely related to limited internet bandwidth when several packets were read in or when joining a large model. The issue has now been fixed in this service pack.

If you are a Tekla Model Sharing on-premises server user, note that this Tekla Structures service pack is not compatible with on-premises server versions older than version 3.13.9. To continue using Tekla Model Sharing, you need to update the Tekla Model Sharing on-premises server to version 3.13.9.

Tekla Model Sharing on-premises server version 3.13.9 is downward compatible. All previous Tekla Structures versions in which Tekla Model Sharing is available, starting from Tekla Structures 21.0, work with this server version.
TTSD-36135 Reinforcement Previously, in IFC 2x3 Export, rebar set groups with group type 'unknown' were exported as a single group with a single GUID, when they should have been exported as individual bars with individual GUIDs. This has now been fixed.
TTSD-37921 Reinforcement Previously, rebar set hooks could appear at the wrong angle in drawings. This has now been fixed.
TTSD-38105 Reinforcement 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.
TTSD-38392 Reinforcement In non-parallel tapered curved rebar groups, overlapping legs were in some cases not offset perpendicular to the bar plane. This has now been fixed.
TTSD-38740 Reinforcement 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.
TSAC-3975 Modeling In the Radial array tool, the box for defining spaces between the copies now adjusts to the size of the dialog box.
TTSD-30409 Modeling The XS_LINE_WIDTH advanced option is not in use anymore, and it has been removed from the Advanced options dialog box.
TTSD-33685 Modeling 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.
TTSD-34621 Modeling 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.
TTSD-35585 Modeling Sometimes, if pours were enabled in a model (XS_ENABLE_POUR_MANAGEMENT was set to TRUE), broken solids caused Tekla Structures to crash when opening the model. This has now been fixed so that Tekla Structures does not crash anymore.
TTSD-37136 Modeling Previously, when using a broken sketched profile in the model, Tekla Structures crashed. This has now been fixed so that the crash does not happen. Broken profiles are shown as sticks instead.
TTSD-37392 Modeling You can now import .lis catalog profiles with a numeric SUB_TYPE value.
TTSD-37491 Modeling In the Snapping toolbar, the list for selecting the snap depth (Auto/view plane) now works correctly.
TTSD-37507 Modeling When creating a spiral beam, the snapping now works correctly.
TTSD-37861 Modeling Previously, selecting a concrete part with the Alt key pressed did not select the rebar sets. This has now been fixed.
TTSD-38386 Modeling When merging complex parts by using the Added material > Attach to part command, Tekla Structures sometimes crashed. This has now been fixed.
TTSD-39025 Modeling Direct modification was not working when using the concrete item command, so the preview and the placing tool were not visible. This has now been fixed.
TTSD-25375 Licensing

Administrators can now set a registry setting so that the license expiry messages will not be seen by users. This can help in situations where overnight processing is run using Tekla Structures - the overnight processing is not impacted when licenses have less than 1 month until the expiry.
For detailed information, see How to disable pop-up messages about the license expires.

TTSD-31795 Installation 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.
TTSD-33042 Installation Model environment information is now taken from XS_SYSTEM. The folder under \Environments\ is used as the environment name.
TTSD-35775 Installation 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.
TTSD-37957 Installation 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.
TTSD-35938 Tools and components 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.
TTSD-37216 Tools and components Previously, concrete cover attributes for parts did not appear in the custom component browser. This has now been fixed.
TTSD-38656 User interface 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.
TTSD-22567 User interface 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 [].
TTSD-30326 User interface When changing the value of XS_VIEW_PART_LABEL_COLOR, you no longer need to restart Tekla Structures to activate the new value.
TTSD-37485 User interface When using DirectX rendering, software rendering is no longer forced in remote desktop connections. You can still use the XS_USE_SOFTWARE_RENDERING advanced option, if needed.
TTSD-38182 User interface Previously, in some models, opening model views could cause Tekla Structures to crash. This has now been fixed.
TSAC-2212 Import, export, interoperability (steel) NC/DSTV: Now the DSTV coordinate system gives the coordinate system for the selected part, and not for the representative part. Also the coordinate system for some plates is now calculated correctly, and Tekla Structures no longer crashes.
TSAC-4017 Import, export, interoperability (concrete) 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.
TSAC-4185 Import, export, interoperability (concrete) EliPLAN export (68): You can now export the geometry of filled slab cores in the plotting data by using the new Export of filled cores setting on the Plotter data tab.
TSAC-4297 Import, export, interoperability (concrete) EliPLAN export (68): You can now export an unlimited number of elements. Previously, you could export 10,000 elements at most.
TSAC-4316 Import, export, interoperability (concrete) EliPLAN export (68): You can now use user-defined template properties with the Weight calculation option Template.
TSAC-4333 Import, export, interoperability (concrete) Export Unitechnik (79): On the Reinforcement tab, you can now select how mesh wire levels are calculated by using the Mesh wire layer level setting. The options are Actual level, Highest level, Wire size, and Manual.
Actual level is the relative wire level in the model, Highest level means all wires in the layer are moved to the level of the wire with the highest z position, Wire size means that the relative level of the 2nd layer is written according to the wire size, and Manual means the 2nd layer wire level can be defined manually.
TSAC-4335 Import, export, interoperability (concrete) Export EliPLAN file (68): You can now specify which property Tag for lifters uses for recognizing lifting embeds. The default value (Default) still uses name or class. Additionally, a user-defined attribute (UDA), or a template attribute (Template) can be specified to use a specific property with a specific value to recognize lifters.
TSAC-4342, TSAC-4367 Import, export, interoperability (concrete)

Export Unitechnik (79): The following options have been added on the Reinforcement tab:

  •  A new Reinforcement export type option called Designated welded bars has been added. This option works in the same way as Fabrication of welded rebars, but you can use it with the Collect based on option to designate the rebars that will form main layers with reinforcement type 1 or 2, while the rebars remain as RODSTOCK depending on object type.
  • A new Reinforcement type option called Use 1, 2 and UDA has been added. When you select this option, the lowest rebar layer,  including all bars in the same direction, is exported with rebar type 1, and all other layers are exported as type 2.

TSAC-4362 Import, export, interoperability (concrete) EliPLAN export(68): Previously, the Plot irregular cutout/recess option incorrectly recognized also rectangular cutouts at the straight ends of slabs. This has now been fixed.
TSAC-4372 Import, export, interoperability (concrete) Export Unitechnik (79): Initially, 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, when using shell-specific coordinate systems. This has now been fixed.
TSAC-4377 Import, export, interoperability (concrete) Unitechnik export (79): Previously, the geometry of embeds in the second shell of a double wall that had the second shell offset lengthwise, was visualised incorrectly in model view when using the Draw geometry in model option. This has now been fixed.
TSAC-4382 Import, export, interoperability (concrete) Export EliPLAN file (68): You can now export the net area of elements using a custom property.
TSAC-4432 Import, export, interoperability (concrete) Export Unitechnik (79): You can now specify a manual Unitechnik mesh type using an UDA option for Mesh type on the Unitechnik tab in the reinforcement user-defined attributes dialog box. If you leave the option blank, automatic mesh type is used like before.
TSAC-4440 Import, export, interoperability (concrete) 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.
TSAC-4468 Import, export, interoperability (concrete) 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 setting on the Data content tab.
TSAC-4469 Import, export, interoperability (concrete) 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 setting on the Data content tab.
TSAC-4472 Import, export, interoperability (concrete) Export EliPLAN file (68): It is now possible to export weep holes only at the middle of elements with a length less than the length specified for the new setting At middle only, length less than on the Plotter data tab.
TSAC-4489 Import, export, interoperability (concrete) 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.
TSAC-4509 Import, export, interoperability (concrete) Export Unitechnik (79): Previously, for double walls with a shell offset at start end, and 1st shell turning enabled in the Double wall turned setting on the TS configuration tab, the second shell of the double wall had an incorrect X axis offset. This has now been fixed.
TSAC-4510 Import, export, interoperability (concrete) 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 in the export selection would 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 with identical position anywhere in the model is written in the field

TSAC-4526 Import, export, interoperability (concrete) BVBS Export: On the Data content tab, in the Position source setting, there is a new option Reinforcement template available.
