Defect number Development area Description
TSAC-1281 Concrete components In Wall layout and Floor layout, when a user-defined attribute value on the UDA/User defined tab is empty, the components now ignore these empty values. This lowers the risk of overwriting these UDAs.
TSAC-1859 Concrete components Previously, Wall layout tools used the circular opening settings for rectangular openings if a circular opening was modified before creating the rectangular opening. This has now been changed.
TSAC-2019 Concrete components Wall layout opening: When copying an opening with direct modification using the Ctrl button, fillers are now correctly copied along with the opening.
TSAC-2253 Concrete components Wall layout: You can now use the Copy special - Mirror and Move special - Mirror commands to mirror wall layouts.

TSAC-3030 Concrete components Previously, in Wall layout connector, the layer-specific attributes (framing case and offsets) in the Wall layout connector dialog box and the actual connection in the model did not match. This issue appeared when the connected primary wall layout had any surfaces other than the last layer.
TSAC-3031 Concrete components In Wall layout, UDA values are now set for the surface treatment when it is the first layer.
TSAC-3041 Concrete components In Mesh bars, extra secondary bars are no longer created in centrally placed bar groups.

TSAC-2349 Steel components In Railings (S77), top rail part cut creation has been improved.
TSAC-2359 Steel components In U.S. Base plate (1047), in some situations, two anchors were previously added to the same assembly. This has now been fixed.
TSAC-2543 Steel components In Shear plate simple (146), clipping the secondary part flange previously depended on the length of the secondary part. This has now been fixed.
TSAC-2554 Steel components In Ladder (S35), in some cases, hoops were previously not created correctly. This has now been fixed.
TSAC-2795 Steel components In Ladder (S35), in some geometrical conditions the hoops were previously created with solid errors. This has now been fixed.
TSAC-2882 Steel components Partial stiff end plate (65) now works correctly when using an L profile instead of a front plate.
TSAC-2918 Steel components In Bolted gusset (11), slotted holes were previously applied incorrectly when using twin profiles as the secondary part. This has now been fixed.
TSAC-2933 Steel components In Welded column with stiffeners (128), top and bottom stiffener welds were previously swapped. This has now been fixed.
TSAC-2944 Steel components In Full depth (184), some cuts were previously not created correctly. This has now been fixed.
TSAC-2956 Steel components In Joist to beam, type 1 (160), the location of the secondary part handle no longer affects the created joist cuts.
TSAC-2990 Steel components In Simple clip angle 2 (82), the copes were previously created incorrectly causing problems with dimensioning in the drawings. This has now been fixed.
TSAC-2991 Steel components In L splice (175) there was an incorrectly created chamfer on the L profile, which was causing problems with numbering. This has now been fixed.
TSAC-3038 Steel components In Stiffened end plate (27) and Partial stiffened end plate (65), the fitting of the secondary part was previously incorrectly created in some cases. This has now been fixed.
TSAC-311 Steel components In Tube splice (6), the creation of welds between the splice plates and the input parts has been improved.
TSAC-3140 Steel components In Gusseted cross (62), the bolt cut length was too small for thick gusset plates. This has now been fixed.

TSAC-857 Steel components Seat type 5 (60) does not create an unwanted fitting anymore.
TTSD-20302 Organizer In Organizer, when you used the W_Project_data property template, the property values of one assembly row in Object Browser were emptied when you exported the object properties to Excel. This has now been fixed.
TTSD-25840 Organizer When you export data to Excel and select the Export without column headers option, the Count column header is not added to the export anymore.
TTSD-27599 Organizer Synchronization has been improved in Organizer. Synchronizing Organizer with models that have assemblies containing a lot of subassemblies/parts is much faster than before.
TTSD-27752 Organizer Organizer performance has now been improved in situations where you open an old model in an environment where a substantial number of property definitions has been changed.
TTSD-15289 Import, export, interoperability DWG drawing export: 2D DWG export now scales the exported file correctly also when US Imperial units are used in the model.
TTSD-20150 Import, export, interoperability Reference models: Setting the visibility of reference model grid layers did not work. This has now been fixed.
TTSD-21401 Import, export, interoperability Reference models: When DirectX rendering was enabled, some lines in a DWG reference model disappeared at certain zoom levels. This has now been fixed.
TTSD-25325 Import, export, interoperability IFC object conversion: Some B-rep cuts were not created correctly, which caused slowness. This has now been fixed.
TTSD-25692 Import, export, interoperability Reference models: Conversion factors from metric to imperial have been added to IFC reference models.
TTSD-26132, TTSD-26655 Import, export, interoperability The profile mapping now works in the following way:
  • Arbitrary profile mapping by name does not need to match the dimensions.
  • Arbitrary profile mapping by name can be set to require dimensions to match by setting the new advanced option XS_CONVERSION_ARBITRARY_PROFILE_MAPPING_BY_NAME_MUST_MATCH_DIMENSIONS to TRUE. The default is FALSE.
  • Parametric profile conversion by profile name mapping does not need to match the dimensions.
  • Parametric profile conversion tries to find a corresponding library profile and if any profile does not match the parameters, the default parametric profile will be used.
TTSD-26532 Import, export, interoperability IFC Object Conversion of steel contour plates uses the prefix defined for plates in Component settings (File > Settings > Options > Profile name > Plate) as the prefix for native plates. You can use prefixes that are supported by your environment.
TTSD-26570 Import, export, interoperability 3D DWG export now works better with z coordinates.
TTSD-26897 Import, export, interoperability The bending radii of rebar hooks are now correctly exported to IFC4. Previously, the main rebar bending radii were applied to all bends including hook bends.

TTSD-28931 Import, export, interoperability DWG drawing export: The DWG export stability has been greatly increased in cases of exporting many drawings at a time.
TTSD-27005 Templates and reports The pull-out attribute now displays the angle values in graphical fields in drawing templates.
TTSD-28854 Templates and reports Modifying a report in Template Editor was very slow. This has now been fixed and the performance of Template Editor has been improved.
TSAC-2869 Drawings Rebar group dimensioning: Rebar groups are now dimensioned in polybeams.
TSAC-2928 Drawings Rebar group dimensioning: Previously, single bar rebar groups gave incorrect number values. This has now been fixed.
TSAC-3003 Drawings Rebar group dimensioning: the dimension mark and line to rebar are now correctly placed in a customized position.
TTSD-15807, TTSD-28271 Drawings A new representation option outline (ignore holes) has been added for meshes on the Mesh content tab in Reinforcement properties.
Additionally, the missing representation option single line with filled ends was added on the Mesh content tab.
TTSD-17795 Drawings The drawing section marks no longer refer to wrong views.
TTSD-20488 Drawings Previously, dragging drawing text from the ruler instead of the ruler handle could cause Tekla Structures to crash. This has now been fixed.
TTSD-21114 Drawings The List hidden objects in templates option in drawings now works more reliably.
TTSD-21243 Drawings Document manager search box now supports macro recording and playback.
TTSD-24534 Drawings The center-to-center distance in bolt marks now works more reliably.
TTSD-25607 Drawings It is no longer possible to open a drawing in Document Manager while direct editing one of its properties. Previously if that was done, any in-progress editing was lost. Now the edit is committed.
TTSD-26142 Drawings Pull-out pictures in drawing templates now have correct leg lengths for rebar set tapered groups.
TTSD-27776 Drawings Reference models: Assembly, cast unit, and single-part drawings: Previously, section symbols were created very far apart and view boundaries were too large if the model contained reference models, even when the reference models were not visible in the drawings. This has now been fixed.
TTSD-27840 Drawings The section marks are no longer referring to wrong views.
TTSD-14480 Tekla Model Sharing Previously in Tekla Model Sharing, saving a copy of a shared model with the Save As option could erase the creation time and creator of model objects. This has now been fixed so that the creation time of model objects is the time that the copied model was saved, and the creator is the user that saved the model.
TTSD-15628 Tekla Model Sharing Previously, when a multi-user model was converted into a shared model, inserting an object could appear twice in the object history. This has now been fixed.
TTSD-16162 Tekla Model Sharing The appearance of usernames in the history of shared models has been unified. The usernames are now shown in the domain\name format.
TTSD-26304 Tekla Model Sharing

In some situations, conflicts in the model could cause the error "Dbvirtual fatal error: internal consistency failure" in read in and restart of Tekla Structures. This has now been fixed.

Note: There may be other reasons for this error. If you experience this error with versions at or above those listed here, contact your local support.

TTSD-26837 Tekla Model Sharing Reference models: Previously in shared models, conflicts with reference models at read-in sometimes caused situations where reference objects could not be shown as invisible in the model view. This has now been fixed.
TSAC-2576 Reinforcement Rebar shape manager has been changed so that multiple sequential bendings which form an arc are combined into one or more bendings (90 degrees or less) with the arc radius. This makes it possible to define bending shapes containing a large radius bending no matter how many individual bendings appear in the original bar geometry.

This functionality is in use when you set the new XS_REBAR_COMBINE_BENDINGS_IN_EVALUATOR advanced option to TRUE. The advanced option can also be set in a suitable .ini file:
SET XS_REBAR_COMBINE_BENDINGS_IN_EVALUATOR=TRUE

When the advanced option is set to FALSE (which is the default value), the bendings appear as multiple bendings and the shape is recognized as before.
TSAC-2605 Reinforcement In Rebar shape manager, a new tolerance value, Curve tolerance, has been added to the Tolerances tab. This value is used for recognizing the arc in a rebar that has multiple sequential bendings.

If the deviation of the rebar leg from the arc is less than the tolerance, multiple bendings are combined to one (or two) bendings with the arc radius as the bending radius.
TSAC-2735 Reinforcement Previously, if you used a Rebar coupler or Rebar end anchor component with rebar sets and manually attached the rebar set bars to another part, the components remained attached to the original part. This has now been fixed. Now both the rebars set bars and the components are correctly attached to the other part.
TSAC-2747 Reinforcement In Rebar shape manager, the value of total length along center line (CLL) was not correct in case the bending radius values and angles were varying. This has now been fixed.

This fix also affects reports if the CLL value has been used for calculations.
TTSD-23905 Reinforcement DirectX rendering performance has been improved when visualizing bent rebars which have a large bending radius.
TTSD-24838 Reinforcement Copying rebar set properties in the property pane now works correctly when you use area selection to select the rebar sets to which you want to copy properties.
TTSD-25246 Reinforcement Modifying multiple rebar set leg faces or guidelines through the property pane now works correctly.
TTSD-26528 Reinforcement In rebar sets, the leg face and the secondary guideline selection was previously lost in the property pane after a modification. This has now been fixed.
TTSD-26787 Reinforcement The property pane is now updated correctly when selecting a modifier command on the Rebar set contextual tab on the ribbon, or on the contextual toolbar. Previously, the property pane occasionally showed the properties of the selected rebar set even if you selected a modifier command.
TTSD-27964 Reinforcement Previously, Tekla Structures crashed when you copied rebar set properties and other objects were selected along with the target rebar set. This has now been fixed.
TTSD-13141, TTSD-25525 Modeling Pour resolving speed has been improved. When opening a model that contains pours, the initial pour resolving is now faster than before. This is especially noticeable when opening models containing a large number of pours.
TTSD-16302 Modeling Weld position is now available on the contextual toolbar in the Construction modeling configuration.
TTSD-24549 Modeling Models created with Tekla Structures versions older than 2017 could get corrupted if they were saved while runtime IDs were disabled. Saving models will now fail if runtime IDs are disabled, which will prevent models from being corrupted for that reason.
TTSD-25123 Modeling Previously, cross sections could sometimes get incorrectly renamed with a redundant extension " 2", when automatically renamed after importing profiles (for example, "A100 2 2", or "A100 2 2 2 2"). Now the deduplication numbers in cross section names are incremented correctly (for example, "A100 3", "A100 4", and so on).
TTSD-25515 Modeling When using the Ortho tool, the snap symbol is now again shown as the snap to any position symbol.
TTSD-25981 Modeling Performance issues in user-defined sketched profile use have been fixed.
TTSD-26240 Modeling Previously, profiles whose SUB_TYPE was defined without quotation marks in the .lis file could not be imported. This has now been fixed.
TTSD-26395 Modeling When you create a concrete or a steel item, the Undo history dialog box now properly shows the correct command name. Previously, the dialog box listed Direct modification as the last command.
TTSD-26760 Modeling Previously, when you loaded a property file that did not contain the assembly numbering value in the property pane, Tekla Structures would crash. This has now been fixed.
TTSD-26815 Modeling The Work plane handler toolbar now works better when saving multi-user models (save and model reopen). The toolbar now keeps the set work plane when saving the model.
TTSD-27047 Modeling Previously, if there was a conflict in a multi-user model and you clicked Review in the conflict message dialog box, Tekla Structures showed an error message when you viewed the conflict log. Now the error message is not shown anymore in conflict situations.
TTSD-27762 Modeling Previously, if a bent plate had several edge chamfers, removing one of them caused others to disappear. This has now been fixed.
TTSD-27782 Modeling In multi-user models, bolts could get incorrect properties in some conflict situations and thus look corrupted. This has now been fixed.
TTSD-27870 Modeling Snapping to the nearest point now works when using the Ortho tool.
TTSD-28122 Modeling Previously, a warning message was shown when you opened the user-defined attributes (UDAs) dialog box for a cast unit sub-assembly from the property pane. This has now been fixed.
TTSD-28434 Modeling Previously, a model with rebar sets could not be reopened after repairing the model if XS_DELETE_UNNECESSARY_INT_ARRAYS was set to TRUE. This has now been fixed.
TTSD-29032 Modeling In the Object Group - View Filter dialog box, the values in the Property column no longer disappear when entered with a space at the end of the value.
TSAC-1998 Tools and components Creating a new group and selecting this group in Layout manager could cause an error when the Group Prefix option in the Layout manager Settings dialog box was empty. This has now been fixed.
TSAC-2579 Tools and components Sometimes, it was not possible to open the Layout line dialog box by double-clicking the thumbnail image in the Applications & components catalog. This has now been fixed.
TSAC-653 Tools and components In Automatic splicing tool, single bars now apply the first splice correctly.
TTSD-27198 Tools and components Previously, clash check could fail to detect clashes involving rebar sets with hooks. This has now been fixed.
TSAC-2237 User interface Pressing Esc to cancel the renaming of a layout point did not work correctly, because the original name was not restored. This has now been fixed.
TTSD-18005 User interface You can now change the space between cut parts on the contextual toolbar in the drawing mode.
TTSD-20908 User interface The construction line extension in the contextual toolbar now follows the unit settings.
TTSD-22240 User interface Objects now remain visible at all zoom levels. Previously, they disappeared from the view at some zoom levels.
TTSD-22777 User interface Previously, when you maximized the Customize toolbars dialog box, the OK, Apply, Discard and Cancel buttons at the bottom of the dialog box were not visible. This has now been fixed.
TTSD-26021 User interface Several fixes have been made to DirectX graphics both in object visualization and performance.
In DirectX views, the clip planes do not disappear anymore in plan views.
TTSD-27392 User interface In the Object group - View filter dialog box, having spaces before or after the text in the Value field no longer causes the text to disappear.
TTSD-27961 User interface Selecting the profile and the material from the profile and material catalogs in the property pane now works correctly when creating parts.

Select this setting and specify a string consisting of numbers referring to the 6 sections of the exported file name mask that are specified on the Main tab. You can type numbers 1 to 6, and delimiters , . _ and - in the free input field to export any combination of strings used in the file name, in any order. For example, 1-2-3, or 2_5_6. Use this option to ensure that both the strings in the file name and within the file content match the expected project and drawing numbers for successful file import.
TSAC-2888 Import, export, interoperability (concrete) BVBS Export: The Advanced tab now contains new options for rounding rebar lengths for 2D bent bars. Mesh and 3D rebars are not affected.
To round the lengths, first select an option for the Round setting. The options are:
Yes - UseS the nearest rounding value.
Up - Rounds the lengths up.
Down - Rounds the lengths down.
The new option Round lengths to rounds the total rebar lengths in the corresponding BVBS field in the header block, and the available values are 1, 5, 10, and 25.
The new option Round leg lengths to rounds the leg lengths in the geometry block, and the available values are 1, 5, and 10.
1 is the default value for both options.
TSAC-3029 Import, export, interoperability (concrete) Export Unitechnik (79): When using file name block options it is now possible to specify input text without delimiters.
