Here is my lab 9.

Doing this lab was similar to what I do at work. We use ArcMap instead of Sketchup though. I could of done a better job outlining the buildings but the snapping was giving me problems. I couldn't find where to disable perpendicular-to-sketch so the buildings weren't always symetrical.

I know I only did 4 buildings, but they're pretty big. I originally did just 10 houses but they didn't have any substructures so I wanted to do something with substructures. One problem I had is that some of the features turned out translucent, I'm not sure why.
