At work I am a daily user of Archicad. I have basically given up using SketchUp as a “content creation” tool for importing models into it. Main problem is that the importer Graphisoft uses doesn’t respect the smoothing SketchUp uses to simulate curved surfaces. Especially in 2D views it is annoying that all edges become visible. The only solution I have found is to open the created GDL object and add a drawn 2D representation to replace the auto-generated one.
