3D modeling

I've been using Google Sketchup for about a year now, and I've started putting together some rough designs for foundation and steel framing.

I also found two excellent models of the Falcon in the 3D Warehouse, which is a part of Google Sketchup. I'm still in the process of measuring and determining how accurate they are. They're definitely useful for determining scale in reference to the foundation layout and other structures that will be near the site.
