Hot on the heels of the new 3D buildings feature for Android, Google has now made it easier to add 3D buildings to Google Earth with the expansion of a few cities in their excellent Building Maker tool.
In particular, the coverage area for Fresno, Lake Tahoe, Austin, Phoenix, Sacramento, San Diego and St. Louis have all been expanded to allow you to model more of the sub-urban areas around the cities. For example, look at the map of Phoenix below; the blue outline shows the previous coverage, while the white outline shows the new coverage — a major increase!
To try it for yourself, simply head over to the Building Maker site and give it a shot. For more about this update, check out the full post on the Google SketchUp Blog.
