To toggle a terrain:
- Get the current view from Google Earth using the Get Current View button. A 2D Google Earth image will appear by default.
- Click on the Toggle Terrain button. The 2D Google Earth image will toggle to a 3D Google Earth image (with terrain).
Note: The Get Current View button actually captures two images from Google Earth, one with terrain and one without terrain. Each image is assigned to a different layer in SketchUp whose visibility is toggled using the Toggle Terrain button.
Tip: Develop your model on the 2D image then toggle to the 3D image and adjust the model's location to the contours of the terrain.
