Google enters the world of 3D software with a free 3D tool called SketchUp.
Google SketchUp (free) is an easy-to-learn 3D modeling program that enables you to explore the world in 3D. With just a few simple tools, you can create 3D models of houses, sheds, decks, home additions, woodworking projects – even space ships. And once you’ve built your models, you can place them in Google Earth, post them to the 3D Warehouse, or print hard copies.
It will be interesting to see where this leads. They offer a ‘pro’ version which handles imports/exports of industry standard filetypes etc.
