I fear that you have wrong forum, this is specific to catia and not for autocad and archicad. you should try in the forum for building engineering and architecture.
However, since we are all a big family weight that, you can transfer your work done by one system to another, through a format of interchange that definitely and the .dxf for what concerns the two-dimensional geometry you can also try .sat.
for any 3d geometries I don't know how to give you indications I don't remember how they are managed by archicad.
