Thought it might be important to point members over to a new project; www.estate3d.com.

Basically the site allows you to have any real-world building shown in the Google Earth 3D buildings layer for $99 USD.

The service is easy to use and is an ideal way for you to get any real-world or proposed real-world 3D models created.

The 3D buildings are then live in Google Earth and, via the Google Earth API, can be embedded on any webpage.

See this recent example of a Virginia School:

(Google Earth Plugin required)

Keep up to date with all things to do with 3D and Google Earth on the Estate 3D blog

Also, become a fan of Estate 3D on Facebook.

All the best.
