I distinctly remember saving out a .SKP file from the 3D window in AC11. I remember because my office has been using SketchUp for a while and I was showing one of the teams how "easy" it was to save out a .SKP file in AC. The .3DS, .DXF, .DWG 3D export engines triangulate and try to regularize the 3D surfaces from the AC model which look like c%*p and are not very usable once imported into SketchUp.
My reseller suggested using the .KMZ (Google Earth) export then converting the file into SketchUp format from Google Earth. I haven't tried it yet, but even if it worked it's a tedious work-around for a simple request.
You may ask why am I trying to go backwards into a conceptual design program from a robust, accurate, object-based modeling software... To make a long story - short, I am in the process of trying to "win them over" and prove that ArchiCAD will work for our offices needs. Every little thing like this issue is a chink in my AC defense armor.
