Re: DIY!
And that's why I don't like to stay beholden to free crumbs form the tables of the mighty. While not quite meant for specifically this, "Sweet Home 3D" may or may not do what you want for _proper_ free - although don't expect to rebuild La Sagrada Familia with it. Of course, if do you need to stay compatible with someone else's sketchup plans, it's all a bit moot...
