Google SketchUp is software that you can use to create, modify and share 3D models. Its easier to learn than other 3D modeling programs, which is why its so popular.
Developed for the conceptual stages of design, Google SketchUp is a powerful yet easy-to-learn 3D software tool that combines a simple, yet robust tool-set with an intelligent drawing system that streamlines and simplifies 3D design. From simple to complex, conceptual to realistic, Google SketchUp enables you to build and modify 3D models quickly and easily.
If you use Google Earth, Google SketchUp allows you to place your models using real-world coordinates and share them with the world using the Google 3D Warehouse.
