• Previewing a SketchUp model in Google Earth is great way to see how your model looks in the context of its surroundings. You start the process in SketchUp, where you optimize the model for viewing in Google Earth. Because Google Earth and SketchUp models can both use a lot of your graphics card’s processing power, your model needs to be as light as possible. When your model is ready, you can preview your model in Google Earth directly from SketchUp. All it takes is a single click!
