Sketchup to STL converter

I worked a bit more on the Sketchup to stl conversion program. It works great for single objects, but more complex scenes (with components) don't convert properly. After looking at the xml in detail it appears that components are defined just once and then referenced along with a matrix to translate/rotate/scale the component within the model. For example, the most complex single object I could make converted perfectly, but when I tried to convert a car from the 3D warehouse it converted the body, along with a single brake rotor, tire, and wheel all centered at the origin. The correct conversion should have made multiple copies of the rotor, tire and wheel with the appropriate matrix transformation applied. I'll add this functionality before the beta release, but for now it's sufficient to continue with the rest of the CAM software.
