All the models in 3D Warehouse are free, so anyone can download files for use in SketchUp or even other software such as AutoCAD, Revit and ArchiCAD - all of which have apps allowing the retrieval of models from 3D Warehouse
3D Warehouse is an open library in which SketchUp users may upload and download 3D models to share. The models can be downloaded right into the program without anything having to be saved onto your computer's storage.
