We'll be getting to some virtual 3D models of two intersecting arcs pieces next and all this will start making more sense.

Click here to start dowloading SketchUp or click her to download the simpler SketchUp Viewer.
If you have questions about any of this stuff, feel free to e-mail me at charlieb@acesscom.com.
