SketchUp (formerly Google Sketchup) is a 3D modeling computer program for a wide range of drawing applications such as architectural, interior design, landscape architecture, civil and mechanical engineering, film and video game design.
We're experimenting with designing in SketchUp. Have you tried it?
Our first project was a multi-color 3D version of their logo.
