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 working on Archicad21 and when saving the model in IFC and then opening it in solibri program then Solibri says that the doors are not linked to the wall although the doors are anchored to the walls in ArchiCad. Second problem is that the 2D lines that are supposed to be shown in the model view are below the actual door. I have been trying different IFC translator settings all day but nothing has worked.
Question seems to be asked on wrong section. I suppose its more: Data Exchange and Information Sharing
Probably it's Translators setup. Try some based on BREP representations. It's usually easier to set it up. Also, remember that there are actually two classes Opening and Doors.
Not sure about the 2D line... how you export them as annotation or part of an element?
