Tekla Structures


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-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-2702 Concrete components Strip footing reinforcement (75): You can now create straight stirrup rebars.
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-2862 Concrete components Beam reinforcement (63), Strip footing reinforcement (75), Corbel reinforcement (81) and Rectangular column reinforcement (83) now have a new U-shape stirrup available.
TSAC-2896 Concrete components In Embedded anchors (8), you can now define a rounding value for anchor distances on the Placement tab.
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-3180 Concrete components Rectangular column reinforcement (83) now creates intermediate bars between side bars when you have defined an equal number of symmetrical side bars, regardless of the symmetry option you have selected.
TSAC-3272 Concrete components Concrete console (110): Previously, the option to cut extra secondary parts was applied to incorrect parts. This has now been fixed.
TSAC-3362 Concrete components Wall layout elementation has been fixed. You can now use the current units (lbs or kg) as the By weight value in the same way as it has been possible for the maximum weight.
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-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-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-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-3185 Steel components In Railings (S77), stanchion skews are now created correctly for all stanchions.
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-3312 Steel components Joist to column, type 2 (163): Stabilizer angle bolts are now created when the secondary part is sloped.
TSAC-3320 Steel components Cold rolled overlap (1): The cleat is now created correctly when using an L profile.
TSAC-3323 Steel components Cold rolled sleeved (2): Bolt spacing is now correctly applied when the gap between the purlins has been specified.

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-3411 Steel components Circular base plate (1052): You can now define the finish property for all parts. On the Anchor rods tab, you can now set the position of the grout to above or below.
TSAC-3446 Steel components Tube gusset (20): Previously, the gusset plate was not created correctly in some cases. This has now been fixed.
TSAC-2653 Task Manager Previously, changing the parent task of a task by decreasing the indent could cause some other tasks to be deleted in Task manager. This has now been fixed.
TSAC-2797 Import, export, interoperability Layout manager: When importing from a layout point file, the name of the group that will be used is now always based on the name of the imported file.
TTSD-14327 Import, export, interoperability IFC object conversion: Sometimes the whole model was converted as Item. This has now been fixed.

TTSD-29888 Import, export, interoperability

IFC export: Previously, exporting a polybeam with a chamfer of over 180 degrees using 3 points did not work correctly. This has now been fixed.

TTSD-29904 Import, export, interoperability DWG drawing export: Drawing DWG export now handles better situations where views are copied from another drawing with layouts.
TTSD-30650 Import, export, interoperability Sometimes the reference model visibility eye icon state was wrong when you opened the reference model, and you needed to click the icon twice to get the reference model visible. This has now been fixed.
TTSD-22294 Templates and reports Template Editor: Numbers that exceed the length field of a template are now correctly truncated with * symbols
TTSD-27756 Templates and reports PDF reports had incorrect page breaks. This has now been fixed.

TSAC-3264 Drawings Template attributes created with the Rebar group dimensioning and Rebar group marking tools now work correctly in dimension marks.
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-20373 Drawings In the Layout editor, moving several templates at once with the Move command now works more reliably.
TTSD-24534 Drawings The center-to-center distance in bolt marks now works more reliably.
TTSD-24666 Drawings Some objects are now drawn in lesser detail when zoomed out in drawings. This gives better performance when working in drawing mode.
TTSD-26235 Drawings There were dimension points missing in copied and linked views. Now dimensions with points that do not have associativity can be copied and linked to another drawing.
TTSD-26418 Drawings The advanced option XS_USE_CROSS_FOR_OPENING_SYMBOL caused an application error with some drawings.
TTSD-26957 Drawings Previously the NUMBER_IN_DRAWING attribute was not working correctly with tapered rebar sets. This has now been fixed.
TTSD-27732 Drawings The update of the curved dimensions in drawings now works more reliably.
TTSD-28039 Drawings The CURRENT_DRAWING.TITLE property now correctly returns a value when used with Select from drawing in drawing view properties.
TTSD-28665 Drawings Previously, in some cases, cast unit drawings could not be opened because graphical objects, such as rectangles, circles, clouds, and polygons, were not rendered correctly. This has now been fixed.
TTSD-28986 Drawings Automatically created radius dimensions were incorrectly drawn the wrong way around. This has now been fixed.
TTSD-29396 Drawings The TOP_LEVEL_BASEPOINT value was not displayed in drawing views when the value was zero. This has now been fixed.
TTSD-29496 Drawings DWG drawing export: Exporting multidrawings as DWG files is now more reliable.
TTSD-29639 Drawings Previously, moving part marks with leader lines could sometimes cause Tekla Structures to crash. This has now been fixed.
TTSD-30329 Drawings Document manager could crash if a large number was entered into the search. This has now been fixed.
TTSD-30731 Drawings Dragging tables in Layout editor has been improved:
- Dragging tables is now smoother.
- You can now drag several tables at one go.
- When you drag tables, snapping is now more reliable.
- When you drag tables, the tables now snap to offsets of 1 mm in metric environments, and 1/16" in the US imperial environment.
- Previously, dragging was not possible in some cases. This has now been fixed.
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.
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-25146 Modeling When creating construction arcs and circles, free snapping (to any position) is now always forced on the current plane.
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-28182 Modeling Previously, in some rare cases, numbering could cause a Tekla Structures model to crash. This could happen at least in the Australasian environment. Now this has been fixed.
TTSD-28422, TTSD-25154 Modeling You can again create construction circles by center point and point on circle. Now when starting the construction circle command, you have 3 options to choose from:
  • Create construction circle by center point and point on circle in view plane (default)
  • Create construction circle by center point, point on circle and point to pick plane (in 3D)
  • Create construction circle by 3 circle points (in 3D)
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-28510, TTSD-29504, TTSD-30166 Modeling Earlier, when creating a view along the grid lines for rotated views, incorrect views were created. This has now been fixed.
TTSD-28673 Modeling Previously, classifying some shapes as non-solids was not correct. Now these shapes are classified as solids.
TTSD-28722 Modeling When you added a new grid line, or removed or dragged an existing grid line of a rotated rectangular grid using direct modification, the grid was not modified correctly. This has now been fixed.
TTSD-28936 Modeling Empty values in the chamfer properties will now be saved as a length of 0 units. This fix also removes the crash that happened in place of the desired behavior.
TTSD-28962 Modeling Previously, when you added a new grid line in a rectangular grid using direct modification, if the neighboring grid lines were located at fractional coordinates, the grid line was not added and the grid labels disappeared. 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.
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-30122 Modeling Views along grid lines were not created properly if the work plane was set to some other plane, for instance, when the work plane was rotated. This has now been fixed.
TTSD-30193, TTSD-30430, TTSD-30389 Modeling Previously, creating views along the grid lines did not work correctly when the grid had a non-zero origin. This 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.
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.
TTSD-27198 Tools and components Previously, clash check could fail to detect clashes involving rebar sets with hooks. This has now been fixed.
TTSD-27819 Tools and components Previously, rebar set modifiers and splitters were hidden in the custom component editor if the XS_REBARSET_SHOW_MODIFIERS_CREATED_BY_COMPONENTS advanced option was set to FALSE. This advanced option should only apply to component instances, not to the component editor. This has now been fixed.
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-15532 User interface The availability of material, thickness and color properties according to the surface treatment types in the property pane has been corrected.
TTSD-24055 User interface Side pane windows no longer move slightly to the left when floated.
TTSD-25122 User interface Side pane windows now stay docked or floated when restarting Tekla Structures.
In addition, clicking on a side pane window header will no longer immediately float the window. You need to slightly drag to detach it.
TTSD-27237 User interface Sometimes, when you created a view, the work plane was moved to the model origin. 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-29273 User interface Earlier, it was not possible to add rectangular or radial grid and grid plane UDAs to the property pane. This now has been fixed.
TTSD-29328 User interface Rebars are now visualized correctly also when they are very far away from the model origin.
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.
TTSD-29794 User interface Model view visualization with DirectX rendering has been improved for reinforcing bars, handles, and stick representation:
  • Curved rebars are not anymore shown with a stick line in certain zoom levels.
  • Highlighting for thin rods now always appears.
  • In rebar set: selecting a modifier does not change the visibility of the unaffected bars.
  • Rebars do not disappear when zoomed to closely from the top/front angle.
  • Snap symbols are the same size in DirectX rendering than in OpenGL.
  • Changing the rendering mode now works after redraw.
  • Parts change color after redraw.
  • Visualization of parts is not affected by redraw in the Ctrl+1 mode.
  • DirectX rebar representation is now correct after rebar creation.
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-1225 Import, export, interoperability (concrete) HMS Export: Added new functionality to include slab cross bar reinforcement in the export.
TSAC-3219 Import, export, interoperability (concrete) Export Unitechnik (79): There is a new option for the Export project coordinates setting on the SLABDATE block data specification tab. Use the new Yes, special variant A option to export Unitechnik files that are compatible with the IDAT stacker software. The new option is only available for the 5.2b version of Unitechnik.
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.
