I´m not a Sketchup user, but from what I know, with Sketchup Pro (or whatever is called now), you can export in IFC format. I suppose that assigning classifications in Sketchup and exporting in IFC would be the best way to manage what you pretend.
If you just import a skp file to Archicad I think you just get a "silly" 3D model made of morphs, but maybe I´m wrong.
