ULTIMATE SOFTWARES

Google SketchUp is software that you can use to create 3D models of anything you like.

Redecorate your living room. Design a new piece of furniture. Model your city for Google Earth. Create a skatepark for your hometown, then export an animation and share it on YouTube. There's no limit to what you can create with SketchUp.

You can build models from scratch, or you can download what you need. People all over the world share what they've made on the Google 3D Warehouse. It's a huge, searchable repository of models, and it's free.
