Auto tracing of Google Earth photo

[rock1]

In SketchUp, I want to show the context around a building in the form of boxes. So there are lots of other buildings that i'd need to trace on an image of google earth using autocad. That would consume a lot of time. Is there a quick way to autotrace such buildings?

Within the last month or two, someone posted about a quick modeling app involving GoogleEarth or other aerial images. There were vid tutorials, and, right now I cannot seem to find it, or remember its name.

I thought perhaps Geosketch from Cogent3d.com would have some relevance. This is what I mentioned, but couldn't remember. Another part of the name is TacForge. It is not a simple tracer.
