Google SkectchUp 6

Design enthusiasts take note: there's a new version of Google SketchUp. This 3D modeling software tool is easy to learn, simple to use, and lets you place your models in Google Earth. One of the cool new features is Photo Match, with which you can trace a photo to create a 3D model of the photographed object or match an existing model with a background photo. To stylize your models, there are features for adding fog, creating sketched effects, watermarks, 3D text, and more. And now the integration between Google Earth, 3D Warehouse and SketchUp is seamless, so that you can easily share and reuse models from other 3D Warehouse users. And as noted above, Google Earth now has the "Best of 3D Warehouse" layer that showcases the highest quality models from SketchUp users.
