Hmm. What is google sketch up? Is it what Klinger and PerRock use? Is it free, and if it isn't how much does it cost? If I have to use GMAX 1.2 to import it, I may be able to do that. Dunno about Blender much.
Earlier versions of google sketchup are free. Google Sketchup Pro however, is gonna cost a big amount of money. Don't know how much though.
