Tekla Structural Designer Integrator July 2020 updates

New Version

Tekla Structural Designer Integrator for Autodesk Revit© 2021 (version 7.0)

Tekla Structural Designer Integrator is now fully compatible with the Autodesk Revit© 2021 package. Integration with regards to imports, exports and merges into this platform are now available and includes the updates listed below.

Updates

The following topics highlight the changes and enhancements in

  • Tekla Structural Designer Integrator for Autodesk Revit© 2020 version 6.01
  • Tekla Structural Designer Integrator for Autodesk Revit© 2019 version 5.02
  • Tekla Structural Designer Integrator for Autodesk Revit© 2018 version 4.03

For fixes and enhancements included in versions prior to those please see Software Updates

Precast Concrete Structural Columns and Structural Framing

[TSD-561]1 - Improvements have been made to the workflow between Tekla Structural Designer (TSD) and Revit© for precast members. From TSD 2020 onwards the precast Fabrication type is now added to the CXL file for members.
The following terminology will be used to describe the updated workflow:

  • TSD → Revit©; Starting in TSD (the originating application) and exporting to Revit (via BIM Integration > Autodesk Revit Export), then importing into Revit using the Revit Integrator
  • Revit© → TSD; Starting in Revit© (the originating application) and exporting to TSD using the Tekla Integrator, then importing into TSD (via BIM Integration > Structural BIM Import).
  • Round tripping; The process of bringing model information back into the originating application from the external application and potentially repeating the export/import process several times.

Round tripping of rectangular precast sections (structural framing and structural columns) is supported.

  • Precast rectangular beams and columns are now mapped to Precast Revit Materials and Families.

Round tripping of the TSD precast beam types of; T, L, Inverted T and Inverted L (available in TSD 2020 onwards).

  • Revit → TSD; unmapped precast members (beams & columns) can now be exported as analysis elements from Revit:
    • On export from Revit, the Export Name is set = Analysis Element in the Revit Integrator - this mapping can then be saved.
    • The sections are imported into TSD as analysis elements (with the default analysis element properties). 
    • The analytical properties of the analysis elements can then be reviewed and edited as required in the TSD model.
    • Round tripping; on import back into Revit, the custom Mapping File (created on export) will allow for the Analysis element to map back to the Revit Precast Family.
  • TSD → Revit; all precast section types are now exported to the CXL file with appropriate geometry (outline) and fabrication:
    • Currently manual mapping is required on import into Revit.
    • Round tripping; you are required to map to the appropriate family and define the symbol (section) geometry in the Revit integrator before export back to TSD.

Framing members with different start and end physical Z-offsets

[TSD-4850]1 - Previously, if the start and end Z offsets of a structural framing member were different, they would not be transferred between Revit© and Tekla Structural Designer. This has now been improved for analytically horizontal framing members.

When utilising this new feature, analytical connectivity is important. It can be observed that when changing the Start Level Offset and/or End Level Offset it is likely that the Revit analysis model becomes disconnected, as seen in the images below.


It is strongly recommended that, before integrating with TSD, the analytical model is connected. For guidance on this please see Using Revit with Tekla Structural Designer - Guidance Notes.

Revit© > Tekla Structural Designer

When updating old or creating new TSD models, the start / end offset value will be identified as Global Offsets. These offsets will be brought back on return to Revit assuming the member remains analytically horizontal.

Tekla Structural Designer > Revit©

When updating existing or creating new Revit© models it’s important to check connectivity of the framing members with differing start/end offsets. As described above, it’s likely that these members will have become analytically disconnected and will need to be manually aligned. Note – if no change is made in the TSD model then the alignment and connectivity will not change.

General Material Walls

In TSD 2020 SP1 onwards users can define General Material Walls. As the name suggests they can be made from any material and have been added to TSD to allow the definition of wall panels that are inherently different to concrete.

A new TSDI_Type, GENERAL_WALL, has been added to allow the integration of these wall types between TSD and Revit.

Do not join slabs of different type

[TSD-2147]1 - The Integrator import process used to merge slabs even when their depths and/or material were different. This has now been fixed and adjacent floor slab panels are no longer merged in their graphical representation if they are of different slab types, or if they are of the same type but have different depths and/or material grades.

Other Issues

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