Corner bolted gusset (57): Previously, when the last selected part was a polygon plate, the gusset was created with an incorrect offset from that polygon plate. This issue has now been fixed.

Kingspan Cold rolled sleeved (28): When the Bolt on Cleat Centre option is set to 50 or 60, the bolts are now a 55 mm backmark.

Kingspan Cold rolled sleeved (28): The rotation of the L profile (such as, RNB and RSA) has been updated.
 

Z pan (S74): Previously, the back wall slope width between the nosing point vertical line and the Z pan back wall was not correctly applied for some pan types. This issue has now been fixed.

In Tekla Structures 2025 SP1, there was an error opening some dialogs, for example DSTV to DXF Converter, after changing the environment. The problem has now been fixed.

Template Editor: The join() and join2() functions always returned 0. This issue has now been fixed.

Textual templates: If the value field formula contained an if-then-endif clause without the else part, the formula would always return 0. This issue has now been fixed.

An application error occurred during report creation. This problem has now been fixed.

Previously, some washers and nuts were missing from the reports. In specific cases where the bolt standard or bolt name was not prioritized in the combining order, washers or nuts were not included in the reports. This issue has now been fixed.

View-specific dimensioning: Recess and hole dimensions are now created faster than before.

In some cases involving complex, curved geometry, unwanted circles could appear in drawings, especially after selecting drawing objects, zooming, or reopening the drawing. This issue has now been fixed.

Section Mark X & Y text offset: When you tried to type in a value, it automatically changed to something else. This issue has now been fixed, and you can type in values normally.

A critical error sometimes occurred when you tried to change the color of an object in a Tekla Structures drawing. This issue has now been fixed.

Drawing image path: The drawing property pane folder browser for images works correctly now. Earlier, an incorrect path might be displayed when you double-clicked any image in a drawing.

Cloning drawings: Sometimes a bigger paper size was used or views were scaled in the new, cloned drawing even though there was no need. This issue has now been fixed.

A Tekla Structures application error occurred when you opened some drawings. This issue has now been fixed.

Dragging polylines in drawings could sometimes cause Tekla Structures to freeze. This issue has now been fixed.

An application error occurred in Tekla Structures 2025 SP1 if you selected a section view and a detail view at the same time and then loaded view settings from the property pane. This issue has now been fixed.

Earlier, when the drawing part setting Orientation mark was selected, all weld outlines could also show orientation marks. This issue has now been fixed.

Printing to PDF: In certain cases, when a drawing contained arcs, printing to PDF could fail. This issue has now been fixed.

Earlier, when loading drawing view properties and modifying drawing view through the property pane, section line, own hidden line and center line properties were not applied. This issue has now been fixed.

Previously, the directory browser component showed an error message when the user tried to open the INP folder on the Advanced tab. This issue has now been fixed.

Tekla Model Sharing: Previously, Tekla Structures might have stopped working when you read in. This has now been fixed.
 

Reinforcement sequence numbering: Previously, rebar assemblies had different reinforcement sequence numbering logic between precast and cast-in-place concrete structures. This issue has now been fixed, and reinforcement objects in rebar assemblies are now always numbered separately from other reinforcement objects in both cast units and pour units.

Rebar sets: An issue has been fixed where the bars in a rebar set that uses a leg surface were incorrectly flipped outside the concrete after a Tekla Model Sharing read-in operation. The same issue occurred after using the Save as command.

Rebar sets: An issue has been fixed where the Split offset value was sometimes incorrectly applied to a splitter placed on or near a leg face edge.

Property pane: Now, when you select a direct modification object, such as a modifier, and copy individual properties, all active property copy switches are cleared when another direct modification object is selected.
 

Live Collaboration: Now, when joining a session with a very large model, Tekla Structures performance has been improved and joining is faster.

Previously, you needed to restart Tekla Structures to activate the value change in the advanced option XS_USE_INTEGRATED_BUILDING_HIERARCHIES. Now the advanced option works correctly as a model-specific advanced option. Reopen the model to activate the changed value.

Previously, the project description entered in the Project properties was not visible when Tekla Structures was started. This has now been fixed, and the entered description is visible.

Previously, when you copied properties from a timber object that had been added by the timber object extension, Tekla Structures might have stopped working unexpectedly. This has now been fixed.
 

Previously, screw group creation did not succeed. This has now been fixed.

Previously, the middle height of some profiles was not calculated correctly. The middle height is now calculated correctly.

Tekla Launcher now supports TC1 bundle licenses.

To enable the on-premises license server, set XS_LICENSE_SERVER_HOST in the user.ini file (preferred option) or in the teklastructures.ini file. Users must have a Diamond, Graphite, or Carbon license in the TC1 bundle and they must belong to and have a valid TC1 organization.

Educational or trial users are not supported for on-premises cases, as they have an online license.

The issue with customized Excel Visual Basic scripts that caused Tekla Structures to stop responding has now been fixed.

In Tekla Structures 2025 SP1, in specific cases, some applications might not start, particularly Bridge creator. This issue has now been fixed.

DSTV/NC: Previously, contour marking was not created correctly for short contour lines, which caused identical parts to have different numbers. This issue has now been fixed.

The Submit feedback button has been added to the Numbering preview dialog.

STEP/IGES export: A hollow, round, rectangular profile that was used as a cutting part was not exported properly in the STEP format. This issue has now been fixed.
