Rebar coupler and anchor tools: In circular structures, such as columns, rebar set end detail modifiers are now created continuously, so they work correctly also when staggering is used. Previously, a short, individual modifier was created for every bar, which did not work correctly with staggering.

Wall panel reinforcement: Hook length calculation for end hook type 0 has been improved. Also, previously, the maximum hook length limitation was too restrictive. Now the hook can extend up to the edge of the rebar.

Wall layout: On the General tab, the list for selecting an option for the height and the global Z coordinates now shows the correct saved option when opening the component dialog.
Additionally, when clicking the Get button in the component dialog, values do not disappear from the dialog anymore.

Mesh bars/Mesh bars by area: On the Picture tab, there are new creation options for the top and bottom bars. The vertical cover thickness for top reinforcement can now be defined from the bottom face and the cover thickness for the bottom reinforcement can be defined from the top face.

Wall layout: Previously, modifying a triangular opening changed the opening to a rectangular opening. This issue has been fixed.

Wall panel reinforcement: When using the Sandwich wall window component for detailing window and door openings in sandwich elements, vertical edge rebars around openings were incorrectly cut at the corners instead of extending properly. Vertical rebars around window and door openings now extend correctly and are no longer cut at the corners.

Wall layout: On the General tab, the top level and bottom level options are now set to empty values when the wall layout is not bound to grid levels. Previously, when the top and bottom levels for binding had values defined, other offset position types did not work properly.

Wall layout: Previously, wall layouts were not updated after a grid level was renamed. This issue has been fixed.

Full depth S (185): Previously, when the secondary part was sloped, the shear tab was created with an incorrect shape. This issue has been fixed.

Stairs detail (1039): Previously, more than one weld was created in the same location. This issue has been fixed.

Railing double curve (95): Previously, incorrect values were stored in the RAIL_RADIUS UDA. This issue has been fixed.
 

Shear plate to tube column (47): Previously, welds between the shear tab and the column were not created correctly when the secondary parts were sloped. This issue has been fixed.

Welded gusset (10): You can now turn off the application of XS_STANDARD_GUSSET_WIDTH_TOLERANCE on gusset width by setting it to 0.0.

Tube gusset (20): Previously, end plates were created as two separate plates in situations where it was not needed. This issue has been fixed.

Stanchions (S76): Previously, stanchions were created with incorrect geometry when input parts had line cuts applied on them. This issue has been fixed.

Stub connection (119): Previously, welds between the middle plate and top plate, bottom plate, end plate and main part were not created correctly. This issue has been fixed.

Layout manager now updates the symbols of layout points both in Layout manager and in the model when you change the Is reference point setting in the layout point properties. For design points imported in the .tflx format, the Is reference point setting is unavailable.

IFC export: User-defined attributes (UDAs) for rebar sets were sometimes missing from the IFC file. These attributes are now exported correctly. 

Point clouds: When you add point clouds from Trimble Connect projects, the point cloud name is truncated at a period only if the name has a valid file extension. Previously, the name was always cut off at the last period, which caused issues if the point cloud name was not a file name with an extension.

IFC4 reference models: Previously, when you used map conversion and a base point simultaneously, IFC4 reference models were positioned incorrectly. This issue has been fixed.

When the language set in the Windows Region settings differed from the language set in the Language for non-Unicode programs settings, and the data you entered in the user interface contained characters not supported in the language set in the Region settings, the characters were handled incorrectly. This issue has been fixed.

IFC export: When adding properties to a property set in the Add property dialog, the NUMBER template attribute now works correctly. When you select NUMBER#1 from the list of template attributes, the #1 suffix is omitted from the attribute name. Previously, the #1 suffix was included, which prevented the template attribute from returning a value.

IFC4 and TrimBIM export: When exporting a model to IFC4 or sharing it as a .tekla file, bolts could appear under the wrong assembly. Bolts are now assigned to the correct assembly in IFC4 export and in TrimBIM-based export formats.

Performance improvement in DWG reference models in drawings: The performance of showing DWG reference models in drawings has been improved. Previously, in Tekla Structures version 2026, making a DWG reference model visible in a drawing took longer than in previous Tekla Structures versions. 

Excel reports: If you exported the Excel output directly to an exFAT-formatted external drive, the resulting XLSX file was sometimes invalid. This issue has been fixed.

Template Editor: Template Editor stopped responding when you changed a picture file from the property dialog and clicked both Apply and OK. This issue has been fixed.

Template Editor: When applying Undo or Redo to a picture file name in the Select Picture File dialog, the picture was not correctly updated in the Template Editor workarea. This issue has been fixed.

Template Editor: Previously, the content in multi-line value fields was not always aligned correctly. This issue has been fixed.

Template Editor: When you open a component property dialog by double-clicking the component in the template workarea and change the component height, and then click OK to close the dialog, the template workarea becomes empty. This issue has been fixed.

Graphical templates: The automatic font size change does not work when only the Min. font ratio free attribute is set. This issue has been fixed.

Insulation in drawings: The minimum width limit for drawing insulation objects in drawings has been removed, and you can now draw insulation objects at any width. Some hatch patterns might not display clearly at very small widths.

Previously, Trimble Connect upload status in Document manager did not change from Up to date to Not up to date when the revision of a drawing was changed. This issue has been fixed.

Previously, when you deleted all tables (templates) from a drawing, undoing the delete left some tables selected. Selecting the tables again did not work correctly and an error message was displayed. This issue has been fixed.

Bolt marks: If you now add bolt marks manually using applied properties, the marks will no longer be removed if you change the bolt size. Previously, manually added bolt marks of bolts with a bolt size equal to the view-level Ignore bolt size value were removed, even though this setting should only affect bolts that were created using view properties.

Merge table cells in rich text files in drawings: You can now merge and unmerge table cells in rich text file content using the new commands Merge cells and Unmerge cells in the context menu. Select the table cells that you want to merge or unmerge and then open the context menu to access the commands.

Text editor in drawings: The full Text editor now loads the content directly from the Text property pane, not from the text object in the drawing. The edits made to the content in the property pane are no longer lost when you open the full Text editor. 
The Save button in the Text editor has been replaced by the Modify button. The Modify button is enabled only when there are pending changes in the text. When you click Modify, the changes are applied to the property pane and to the text object, and the Text editor remains open.

Text objects in drawing: When editing plain text, you can no longer use the Tab key to add horizontal tabulation. If you use the Tab key, the result is not shown in the drawing. Adding tabulation in plain text objects is now prevented.

In the Solid checker tool, the translation of "Fixed" in other languages previously meant "stationary". The translation has been corrected to mean "repaired".

Previously, two almost identical plates in steel assemblies sometimes did not match correctly when comparing or cloning assemblies. This matching now works better for those plates.

Text objects in drawings: The keyboard down arrow now works in plain text and rich text content in the drawing property pane.

Cloning: Earlier, in rare cases, when you cloned assembly or single-part drawings, Tekla Structures might terminate unexpectedly. This issue has been fixed.

Rebar marks in rebar dimension marks: If a rebar already has a rebar mark, adding a rebar dimension mark with the Include rebar mark attribute now neither creates a new rebar mark nor changes the associativity of the existing mark.

Detailed object level settings: The drawing-level detailed object level settings work correctly again and are used when the view-level detailed object level settings are disabled. Previously, the drawing-level detailed object level settings were not used in this situation.

Previously, words in a drawing text object overlapped when the text was aligned to the center or to the right, and some text was bolded or there were different font sizes in the text. This issue has been fixed.

Previously, Document manager could stop working when the data type of a user-defined drawing attribute was changed. This issue has been fixed.

Previously, zooming in a drawing could be slow when reference models were set to be visible. Now zooming has been improved to work faster and smoother.

Weld section line presentation in drawings now works correctly. Earlier, part section line properties were used instead of weld visible line properties. This caused some welds to be visible even if set to invisible in weld properties.

Previously, when you double-clicked a text object with several lines of text in an open drawing, then edited the text in the Tekla Structures full Text editor and saved the changes, all line breaks were shown as square box symbols in the drawing and in the drawing printed to PDF. This issue has been fixed.

Earlier, when you created a drawing filter and selected the Multi-select from drawing option in the Value list, the objects located inside the selected area were not highlighted in the drawing. This issue has been fixed.

Previously, the CENTER2, DASHDOT2, DASHED2, DIVIVE2, and DOT2 line types were missing the example images in drawing view properties. This issue has been fixed.
 

Tekla Model Sharing: Previously, canceling a write out could save the model incorrectly and prevent further sharing. Now, canceling works correctly and the model returns to its previous state.

Rebar meshes: Tekla Structures no longer stops working when creating or modifying bent rebar meshes where the start or end offset is a negative value and the bending radius is large enough to eliminate the straight part of the first or last leg of the bars.

Rebar groups: An issue has been fixed where modifying multiple rebar groups that had standard hooks with different angles caused hooks to be converted to custom hooks.

Rebar groups: Previously, when you opened a model from an older Tekla Structures version, some curved tapered rebar groups could lose their spacing information and show the wrong number of bars. This information is now retained correctly.

The direct modification commands that can be finished with the middle mouse button or the Enter key, such as the bolt creation commands, can now be finished also by pressing the spacebar.

Previously, the user-defined attributes (UDAs) dialog was sometimes showing wrong options for some properties. This has now been fixed.

Contextual toolbar now shows user-defined attributes (UDAs) more reliably.

In round-to-round pipe parametric profiles, the inner contour end face is now created correctly.

Previously, Tekla Structures could have stopped working unexpectedly when you set a variable cross-section profile for a spiral beam. This has now been fixed.

Some cast-in-place concrete part solids were not shown correctly in model views in Tekla Structures 2026. This issue has been fixed with TTSD-77160.

Previously, when you exported a TrimBIM file with Surface treatments and surfaces selected in the export settings, rebar set leg surfaces were also exported. This caused visualization problems and added no useful information to the file. Now, rebar set leg surfaces are no longer exported to TrimBIM.

Previously, when unfolding bent plates that contained added material, Tekla Structures would incorrectly create unwanted copies of the added material. This could cause problems in drawings and NC file exports.

Now, the unfolding works correctly with added material, and no additional copies are created.

Some cut openings in cast-in-place concrete parts were not shown in pour views in Tekla Structures 2026. This issue has been fixed with TTSD-77160.

Previously, when copying objects from another model, dynamic user-defined attributes (UDAs) that were created by applications were not copied with the objects.

Now, these UDAs are copied correctly when you copy objects from another model.

Pour management: A fallback method used when creating pour solids, which was not available in Tekla Structures 2026, has now been restored in Tekla Structures 2026 SP4. This method again processes cast-in-place concrete parts as they are, without clipping them.

Previously, when creating a new grid, the grid could get the same name as an existing grid in the model, possibly causing conflicts.

Now, Tekla Structures automatically adds a number suffix to the grid name to ensure that each grid has a unique name.

Tekla Launcher: Previously, Tekla Launcher always displayed the Trimble Connect project selection dialog when creating a new model, even if you did not plan to use Trimble Connect for that project.

Now, when you create a new model in Tekla Launcher, clear the Start Trimble Connect collaboration checkbox to skip the dialog. Tekla Launcher remembers your selection for future models.
 

Trimble Connect: Previously, when uploading PDF drawings from Tekla Structures to Trimble Connect, the property set library and data table would become unavailable for other project members in Trimble Connect. This has been fixed.

If your project was already affected by this problem, the user who originally printed and uploaded the drawings to Trimble Connect can repair it using the Trimble Connect Property set repair tool available in Tekla Warehouse.

Previously, the contextual toolbar could cause Tekla Structures to slow down noticeably when you selected more than 1000 objects at once, as it tried to process all selected objects. 

Now, the contextual toolbar automatically hides when you select more than 1000 objects to prevent this slowdown.

Previously, if a plug-in failed, for example, due to invalid input and resulting missing output, the plug-in was not properly deleted and there could be errors. This issue has been fixed.

Previously, when you selected an object through the component browser in the custom component editor, the property pane did not show the object properties. This has been fixed, and the property pane now shows the properties.

STEP/IGES export: Bolt holes are now exported properly in complex aluminium profiles.

STEP/IGES export: Curved polybeams are now exported more correctly, including their bolt holes.

STEP/IGES export: Countersunk bolt holes are now exported correctly in the STEP and IGES formats.

DSTV/NC: Previously, if you created an NC part list right after opening a model, folded polybeams could show the wrong length. That wrong length could then stop you from creating NC files and unfolding drawings. The length is now calculated correctly when you create the list.

STEP/IGES export: The export now contains three new options for splitting the export:

• One file per part position: Writes each distinct part position to its own file containing one representative geometry. The object count is appended to the resolved file name by default. For example, if part position is used in the file name template and five parts have position P4, the file contains only one object and is named P4_5. Parts without a part position are skipped and listed in the export log.
• One file per assembly position: Writes each distinct assembly position to its own file containing one representative geometry. The object count is appended to the resolved file name by default. For example, if assembly position is used in the file name template and three objects share assembly position A1, the file contains only one assembly and is named A1_3. Objects that cannot be resolved to an assembly position are skipped and listed in the export log.
• One file per phase:  Writes each phase to its own file. Groups exportable objects by both PhaseNumber and PhaseName, so phases with the same name but different numbers are written to separate files. With selected objects, only phases represented in the selection are exported; empty phases are not exported. Objects without a valid phase are skipped and listed in the export log.

STEP/IGES export: There are some new element options available for the export file name:

Profile name

Profile type

Phase number

Phase name

STEP/IGES export: Previously, when the export generated multiple files, a sequence suffix (_1, _2, _3) was added to every file name, even if each file already had a unique name. Now, sequence suffixes are added only when two or more files in the export would otherwise have the same name.

STEP/IGES Export: Bent plates, lofted plates, and spiral beams are now exported as faceted Brep, including their bolt holes.
