Google SketchUp
On April 27, 2006, Google announced Google SketchUp, a freely downloadable version of SketchUp. The free version is missing some functionality of SketchUp Pro, but includes integrated tools for uploading content to Google Earth and to the Google 3D Warehouse, a repository of models created in SketchUp. A new toolbox enables a viewer to walk around and see things from a person's point of view; it adds labels for models, a look-around tool, and an "any polygon" shape tool.
The free version of Google Sketchup can export 3D to .dae and Google Earth's .kmz file format. The Pro version extends exporting support to include the .3ds, .dwg, .dxf, .fbx, .obj, .xsi, and .wrl file formats.
Google SketchUp can also save elevations or renderings of the model, called "screenshots", as .bmp, .png, .jpg, .tif, with the Pro version also supporting .pdf, .eps, .epx, .dwg, and .dxf.
Neither is available in a native format for Linux, or Mac OS earlier than 10.5. However, Sketchup v.8 use under Wine has been rated "Gold".
GPS location information is always stored in the KMZ file. The building designs themselves are saved in SKP.
