To use Building Maker you must have the latest version of the Google Earth browser plug-in installed. The video below demonstrates Building Maker better than I can describe it.

The intent of Building Maker is to enable users to submit their creations to the Google 3D Warehouse. Using Building Maker could be a fun way for students to create 3D models of their communities for use in Google Earth.
