3D Warehouse
The Google 3D Warehouse is a collection of 3D models of buildings, bridges, cars, spaceships, futons, dinosaurs and everything else in the universe. You'll find things that exist, things that used to exist, and things that only exist in the minds of the people who built and uploaded them. The 3D Warehouse is completely free for everyone to find and share models of anything they like, especially woodworking related items.

Google SketchUp
Google SketchUp is software that you can use to create, modify and share 3D models. It's easier to learn than other 3D modeling programs, which is why so many people are already using it. We designed SketchUp's simplified toolset, guided drawing system and clean look-and-feel to help you concentrate on two things: getting your work done as efficiently as possible, and having fun while you're doing it.
