Google SketchUp 3D

Google SketchUp is an easy-to-learn 3D modeling program. Using a few simple tools we can create 3D models of houses, sheds, decks, home additions, woodworking projects-even space ships. You can add details, textures and glass to your models, and design with dimensional accuracy. Once built, we can place our models in Google Earth, share them with others by posting them to the 3D Warehouse, or print hard copies
