Jayson, sorry for the horrific delay in my responding to your request re 3D
CADD problems for a competition, my travel and work schedule of late have not
allowed much time here. Looks like Pat and JC have already got to you and I
can recommend both of them to you highly. If you have not already done so
please take them up on their offers, each can provide you with a wealth of
usefull information and assistance.
Let me know if you are still looking for more problems and/or have any
additional questions. I assist with CAD competions around the world and try to
keep a collection of problems on file from these.
