mbrecken:
If you are using ArchiCAD 9, try using the older translator (DXF-DWG In-Out_2k), which shows up as DXF-DWG Translator Setup (8.1 Translator) in the tools menu after you have loaded the add-on (this add-on is not part of the standard installation, I forgot where it is stashed, maybe the Goodies folder). You may need to remove the standard DXF-DWG In-Out translator. I know that there are problems with the standard translator relating to custom fill origins and rotations.
