1. Preview your model before publishing to the Google 3D Warehouse.
- Delete any extra geometry, inside or outside of your building.
- Turn your hidden geometry on, View -> Hidden Geometry, and check for excess hidden lines.
- Limit the number of faces (polygons) in your model, Window -> Model Info -> Statistics. Less then 500 is ideal for most buildings.
2. Geo-locate your buildings correctly.
- Make sure your building is aligned with the base of the building, not the roof of the building in your Google Earth snapshot.
3. Avoid floating buildings!
- Toggle the terrain button and confirm that your building is planted in the ground.
4. Preview your model in Google Earth
- Export your model to Google Earth, File -> Export -> 3D Model and choose Google Earth 4 (.kmz).
- Open the .kmz in Google Earth to check that it accurately represents the building.
- If you see flickering (z-fighting) on the model in Google Earth but not in SketchUp, this means you imported your textures incorrectly. This happens when you import your textures with the "image" radio button selected instead of the "texture" radio button. To fix this, delete your incorrectly applied images and reapply the images with textures.
5. Make sure that each SketchUp file is under 10MB for a successful upload to the 3D Warehouse.
6. Publish buildings to the 3D Warehouse as individual models (eg. do not publish your campus as a single file)
