Google SketchUp 5.0.295

Google SketchUp is a free, easy-to-learn 3D-modeling program with a few simple tools to let you create 3D models of houses, sheds, decks, home additions, woodworking projects, and even space ships. You can add details, textures, and glass to your models, and design with dimensional accuracy. You can place your finished models in Google Earth, share them with others by posting them to the 3D Warehouse, or print hard copies. Google SketchUp is a great way to discover if 3D modeling is right for you.
Good software is software you can learn. Even the most powerful tool is useless if you cant figure out how to make it work. Most people get rolling with SketchUp in a couple of hours. Video tutorials, an extensive Help Center and live training classes mean that anyone who wants to make 3D models with SketchUp, can.
