This was a project that I did for the Inventor class I took in college. I was the only sound guy in

the class. If you don't know about Inventor, it is another program by Autodesk (the company

that makes AutoCad). It concentrates mostly on 3-D drafting where moving parts

are required. It is mostly used by the manufacturing industry, but can also be used

to design moving scenery and other motion-controlled things in theatre.
