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 read IFC 2x3 Reference Guide for ArchiCAD 13 which said that "An element's GUID in ArchiCAD is not the same as its GUID in IFC". But I used Solibri model viewer show that the GUID is same in ArchiCAD and IFC, does the Reference wrong? Do you have experience about this?
