UPDATE!
After some banging around this morning I discovered I can get the link to work manually between Revit 2024.2.x and Twinmotion 2024.1 with the following steps:
- Open both TM and Revit. Open your Revit project and navigate to a 3D view.
- If you attempt a direct link import in TM it will show “No source available”
- In Revit’s Twinmotion menu select “Open in Twinmotion” and let it fail. (It will tell you TM is not installed.) Close the dialog.
- Now repeat the direct link import in TM and you should see your Revit project is now selected as the source. Choose your options and import.
- Go back to Revit and synchronize and your model should appear in TM.
