The integrator now checks the active Revit model for any instances containing Tekla Structural Designer data, indicating prior data exchange. If any elements are found, the First time import option is automatically disabled forcing the Update existing model option to be used instead.

An intermittent error message “There is a circular chain of references among the highlighted elements” has been resolved.

The Integrator software currently requires families to be installed locally. An import error occurs when there is no local Revit content installed.

The Integrator wizard has been updated to ensure users review any mapping errors caused by unmapped families.

Fig 4. The Section and Material Mapping dialog now highlights unrecognised Structural Column and Structural Framing types, with the Review Mapping option now pre-selected.

If these mapping errors aren’t resolved, the Next button in the wizard is disabled, preventing further progress.

An intermittent error where model instances were not directly selected within the Create Analytical Model command, but were connected to selected instances has been fixed.

The Create Analytical Model command now checks the model and removes any analytical associations where model instances are not valid. This avoids any potential errors being encountered and allows the command to complete successfully.

The Create Analytical Model command now detects and removes any analytical instances that are not associated with a physical model instance. A new checkbox option allows users to choose whether these unassociated analytical instances should be deleted during the process.

Revit IDs of all deleted analytical elements are now reported in the log file.

When updating a model, the integrator may report that Structural Column locations have changed, even if the location remains in the same physical position.

This issue has now been addressed.

When re-importing columns into Revit via the integrator, user-defined columns or those with the AutoDesign flag were incorrectly positioned if specific rotations and offsets were applied.This issue has now been resolved.

An issue affecting the automated mapping of CHS 270.0 and CHS 457.0 profiles has been resolved.

Fig 11. Log file showing duplicate GUID warnings.

The handling of duplicate GUID references has been improved. The warning message has been clarified, and when duplicates are detected, the oldest object retains its GUID. Both the Revit model and the CXL file are then updated accordingly.

Additional error handling has been implemented to help identify the source of duplicates caused by copied instances in Revit. Users should save the Revit model after the export process is complete.

When working within a workshared Revit project, it is critical to ensure that models are synchronised and that no elements are actively checked out by other users during the Create Analytical Model or import / export processes.

To support a more reliable workflow in workshared environments, we have introduced enhancements that automatically manage element ownership and ensure consistency during data transfer operations.

Import processes

Regardless of the element selection method, the integrator checks out all instances in the Revit model.

This is necessary because imported level changes can potentially impact instances throughout the entire model, while position changes to selected instances may also affect connected instances outside the selection area.

Export / Create Analytical model

The integrator checks out only the selected instances, using either the Entire Structure Model or the Selected part of Structural Model option shown in figure 13.

This ensures that the exported data remains accurate, is protected from interference by other users during the process, and allows other team members to continue working on unselected areas of the model without disruption.

Other minor issues have been addressed based on your feedback. Thank you.
