Fixes

Defect number Development area Description
TSAC-2395 Concrete components In Wall layout, an error message is now shown in some situations to avoid Tekla Structures from crashing. This error message "Z0" is harmless but we recommend that you save your model when the message is shown.
TSAC-2720 Concrete components Automated reinforcement layout - double tee beam (51): You can now use the Ignore cutouts in strand layout setting on the Attributes tab to ignore cutouts when counting the strand layout.
TSAC-2734 Concrete components The Update rebar attributes tool now has a new Update (phase only) button with which you can update just the phase of all rebar coupler/end anchor parts.
The existing Update button still functions as before. You can use the Update button to update the coupler/end anchor-specific UDA values in addition to the phase of coupler/end anchor parts.
TSAC-2963 Concrete components Reinforcement mesh array in area (89) now creates the reinforcement mesh correctly for the defined polygonal area. Previously, the mesh was not created in some corners of the area and in some cases the mesh extended outside the area.
TSAC-3132 Concrete components Wall layout dialog box has been fixed. Now it works more logically when modifying only the available properties of H, Z1, and Z0 (height, top and bottom level) on the General tab.
TSAC-3366 Concrete components The Mesh bars and Mesh bars by area dialog boxes are now opened without an error message.
TSAC-3475 Concrete components Mesh bars / Mesh bars by area: On the Detailing tab, the Create cuts around selected parts feature has been improved. Filter recognition in the list of filters has been improved and the selected filter is now visible when you reopen the component dialog box in the model.
TSAC-3513 Concrete components Anchor (10): The top and bottom offsets were incorrectly calculated for parts with complex parametric profiles and parts that have been cut. This has now been fixed.
TSAC-3523 Concrete components Concrete console (111): Assembly type is now correctly loaded.
TSAC-3524 Concrete components Concrete beam-beam (112): The box used for defining the length of the first washer on the Anchors tab is now dimmed properly.
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-3595 Concrete components Concrete console (110): The cast unit numbering standard is now loaded and saved properly for all parts.
TSAC-818 Concrete components Mesh bars: You can now set the bar edge distance as a negative value. Note that this will only offset the bars. To get a fully offset mesh, set the cover thickness for the sides on the Bar end conditions tab to a negative value.
TSAC-1069 Steel components Cold rolled sleeved (2): It is now possible to select the bolt size and bolt standard from catalogs.
TSAC-1528 Steel components Cold rolled sleeved (2): The sleeve profile is now included in the bolted parts.
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-2807 Steel components Bolted gusset (11) now works in the same way in different Tekla Structures versions.
TSAC-3010 Steel components Cranked beam (41): Vertical positioning of the bolt groups is now working correctly.
TSAC-3054 Steel components Column with stiffeners (188): Shear tabs are now correctly placed when the main part is created from plates.
TSAC-3177 Steel components Cold rolled overlap: Previously, when using user-defined profiles as secondary parts, the cleat was positioned incorrectly. This has now been fixed.
TSAC-3204 Steel components Bolted moment connection (134): Flange plate clearance now works correctly when the connection is connected to the main part web.
TSAC-3271 Steel components Column splice (132): You can now define the number of web bolts when using a division plate and angle profiles as the connection.
TSAC-3295 Steel components Splice connection (77): Weld preparations for web plates are now created correctly and do not cause solid errors anymore.

TSAC-3326 Steel components Seat detail type 1 (1033): If the system default value is not found, the default material is now correctly set from File menu > Settings > Options > Components.
TSAC-3336 Steel components Create hole around part (92): Previously, when the profile length was shorter than the profile height, the cut was created incorrectly. This has now been fixed.
TSAC-3368 Steel components Splice type 1 (56): The Round web plate dimensions option on the Parameters tab now works correctly.
TSAC-3446 Steel components Tube gusset (20): Previously, the gusset plate was not created correctly in some cases. This has now been fixed.
TSAC-3536 Steel components Tube gusset (20): Previously, both above and below line welds were created as above line welds. This has now been fixed.

TSAC-3263 Drawings Rebar group marking: Total number in cast unit is now correct for rebar sets.
TSAC-3325 Drawings Rebar group dimensioning: Rebar group dimensioning no longer causes crashes. The crashes were caused by incorrect part bounding boxes and incorrectly counted view restriction boxes.
TTSD-25906 Drawings The Delete button in Document manager has been improved. Now, if you have selected documents in Document manager, clicking Delete deletes selected documents. You can no longer accidentally delete model objects by clicking Select objects in the model for selected drawings and then clicking Delete.
TTSD-26477 Drawings The rebar dimension line now works better for those rebar groups that do not have a planar shape, such as a 3D shape.
TTSD-2741 Drawings "ą" diacritics could not be used in drawing text window - using shortcut for this letter selected entire text. This has now been fixed.

TTSD-31166 Drawings Opening general arrangement drawings that were created in Tekla Structures versions older than 2017 is now faster.
TTSD-27196 Tekla Model Sharing Previously, when a reference model was locked locally before read in, you had to reopen the model to update the reference model version. This has now been fixed.
TTSD-30323 Tekla Model Sharing In Tekla Model Sharing, object locks have now been reinforced, so that users in different organizations can no longer accidentally unlock each others' objects or modify the privileges.inp file.
TSAC-3344 Reinforcement In Rebar shape manager, the rule operand REVERSED was not previously available for curved/circular bars, and therefore it could not be used in shape definitions. This has now been fixed.
TSAC-3345 Reinforcement In Rebar shape manager, some extra leg/bending rule operands were previously occasionally shown with short curved bars. These obsolete operands are not shown anymore.
TSAC-3428 Reinforcement Rebar shape manager has been changed so that a bar that contains multiple sequential bends forming a circular arc (according curve tolerance) is converted to an arc only when the bending angles are smaller than ~34 degrees. In practice, a 10-sided polygonal stirrup will never be converted to a circular arc but if the stirrup contains 11 or more sides, it may be converted to a circular arc if it fulfills the curve tolerance value.
TTSD-14083 Reinforcement Clash check now takes into account rebar set concrete covers and works correctly with protruding rebar set bars.
TTSD-28607 Reinforcement Previously, Tekla Structures could crash if a rebar set contained an end detail modifier defining a custom hook with zero angle. Sometimes such hook definitions could also prevent the model from being opened. This has now been fixed.
TTSD-27826 Modeling In some cases, for example, when the plane of a part face or an opening face ran through an opening in the part and its pour break plane, the pour break was not created or it became invalid. This has now been fixed.
TTSD-29098 Modeling When using a main part UDA value in the assembly or cast unit position, Tekla Structures erroneously showed the default value of the UDA. This has now been fixed.
TTSD-29301 Modeling Previously, when you had selected all parts in a cast unit with the Alt key pressed and you had the Select components selection switch active, trying to deselect a custom component sub-assembly in the cast unit by clicking the sub-assembly with the Ctrl button pressed could cause Tekla Structures to crash. This has now been fixed.
TTSD-29400 Modeling Earlier, when diagnosing models containing spiral beams with a 360-degree turn and no total rise, model inconsistencies were reported. When repairing such models, these spiral beams were removed from the models. This has now been fixed.
TTSD-29673 Modeling Parts whose material is Formwork_undefined are no longer added to the pour unit when you use the Calculate pour units command. However, you can manually add these parts to pour units if the cast unit type is precast.
TTSD-29820 Modeling Profiles with zero decimals (for example, C130X2.0) were not shown correctly in the model (their detailed shape was lost and did not contain roundings, for example). This applied to fixed profiles which were created from sketched profiles. Now this has been fixed.
TTSD-31395 Modeling Certain types of pour breaks now work on slabs with recesses.
TTSD-31525 Licensing The error message for an expired Tekla Structures license has now been fixed.
TTSD-30736 Analysis and design Previously, the selected analysis part handle disappeared when moving the cursor in the view. This has now been fixed.
TTSD-30763 Analysis and design Previously, moving an analysis node did not create the correct result when multiple parts were connected to the node. This has now been fixed.
TTSD-21410 Tools and components Outdated locked custom part instances are no longer automatically updated when they or their objects are unlocked.
Outdated custom parts are updated to use the latest definition with modify when the custom part or its objects are not locked anymore.
TTSD-27133 Tools and components The Shape value type is now available in the custom component editor. You can use it to open the shape catalog from the custom component dialog box.
You can use the new value type in existing custom components that include items by editing the components.
TTSD-28207 Tools and components Previously, there was an error when publishing a custom component in the Applications & components catalog when another component of a different type with the same name as the custom component already existed. This has now been fixed.
TTSD-27766 User interface The work plane was sometimes moved to the model origin when the view was created of the selected objects. This has now been fixed.
TTSD-28663 User interface Previously, when you modified a UDA that did not affect numbering by using the property pane, Tekla Structures still considered the model object as needing renumbering. Now this does not happen anymore.
TTSD-28885 User interface Previously, the work plane was set to the model origin when creating default views. This has been fixed and the work plane now remains in the previously set location.
TTSD-29452 User interface In some rare cases when dragging a table in Layout editor, the Tekla Structures user interface was no longer responding. This has now been fixed.
TSAC-2527 Import, export, interoperability (steel) NC files: Skew cuts were not created well when were at a certain angle. This has now been fixed.
TSAC-2470 Import, export, interoperability (concrete) Export Unitechnik (79): Previously, when a double wall shell was created from more than one part and the Cut outer assemblies option was switched on, the embeds in the secondary part were missing from the export with certain Export Groups settings. This has now been fixed.
TSAC-2594 Import, export, interoperability (concrete) Export EliPlan file (68): When using the Export using filter setting, the logging of excluded cast units has been improved.
TSAC-3171 Import, export, interoperability (concrete) Export Unitechnik (79): On the TS configuration tab you can now set Export CONTOUR to Simplified, which exports a simplified contour using 4 x,y corner points of the element.
TSAC-3357 Import, export, interoperability (concrete) Export Unitechnik (79): On the Reinforcement tab, you can now select to export braced girders within the STEELMAT block. By default, the braced girders are exported outside of the STEELMAT block.
TSAC-3418 Import, export, interoperability (concrete) Export EliPlan file (68): Hollow core slab thickness is now read from the profile instead of the geometrical thickness (in case the complete top or bottom face is cut).
TSAC-3447 Import, export, interoperability (concrete) Export EliPlan file (68): All geometrical data with the Plotter and Pieces blocks are now exported rounded to the closest millimeter in metric environments.
TSAC-3484 Import, export, interoperability (concrete) Export Unitechnik (79): Previously, braced girders within the STEELMAT block were not exported when the STEELMAT block was otherwise empty. This has now been fixed.
TSAC-3488 Import, export, interoperability (concrete) Export  Unitechnik (79): Braced girders modeled with only two chords are now correctly recognized and exported.
TSAC-3518 Import, export, interoperability (concrete) Export Unitechnik (79): When the BRGIRDER block is exported within the STEELMAT block, the STEELMAT insertion coordinates are now correctly adjusted in case the girder minimum coordinate points are outside the mesh.
TSAC-3541 Import, export, interoperability (concrete) Export Unitechnik (79): The Extend contour and add formwork option on the TS configuration tab has been improved. Now, formwork is not added if there is already an embed with the same geometry. Also, the contour is not extended for electric tube embeds.
TSAC-3543 Import, export, interoperability (concrete) Export Unitechnik (79): The Double wall turned setting  on the TS configuration tab has been improved. The No option has been renamed to option No, one coordinate system and new option No, shell-specific coordinate systems has been added to export second shell in the Z direction from the bottom of the pallet upwards.
TSAC-3555 Import, export, interoperability (concrete) Export Unitechnik (79): Previously, when you exported braced girders within the STEELMAT block but with mesh filtered out, the reinforcement block was exported as empty. This has now been fixed.
TSAC-3565 Import, export, interoperability (concrete) Export Unitechnik (79): The height of braced girders is now calculated more accurately. The height is now measured as the distance between the top and bottom rod center line points.
TSAC-3592 Import, export, interoperability (concrete) Export Unitechnik (79): Electric tubes are now not excluded for the whole length when you use the Cut outer assemblies option together with non-turned double walls.
