About model and data exchange with 3rd party solutions: Revit, Solibri, dRofus, Bluebeam, structural analysis solutions, and IFC, BCF and DXF/DWG-based exchange, etc.
I am able to "save as" a Twinmotion file from ArchiCAD. When importing into Twinmotion, it goes through the process and seems to be imported. The name of the file shows up in the lower part of the window, but no model is visible the upper part of the window.
