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.
Just so you are aware you posted your inquiry in the wrong section of the user forum. This section is designed for suggested improvements to Archicad and not intended for problems you are having. I have been publishing to DWG in 10 without incident. Try a different translator or change some of the settings in the translator. The "special built in translator" seems to work fine, but I usually restrict the translation to visible layers only to help keep clutter out of the consultants files.
