The Google 3D Warehouse is a website where millions of SketchUp users from around the world are able to find, share, store, and collaborate on 3D models. In many ways it's similar to YouTube, only the warehouse contains 3D SketchUp models, rather than videos. On the Warehouse, you'll find tens of thousands of SketchUp models of real world products that have been uploaded by the companies who make and sell those products. In the CertainTeed collections, designers will find an array of 3D models and texture libraries that can be added to your SketchUp projects.
