Rhino - Learn to use Rhino.

As the others have said, this is a pretty ambitious project for a beginner.
You should work though some basic tutorials and spend some time searching and reading in these forums. Not many things about Rhino that haven’t been asked about (and answered) here.
You’ll get more help if you try to do as much as you can. Then post screen shots and files here with specific questions about the parts you’re having trouble with.
