Thanks Michael!

Could I see one short input line for reference?

FYI: It's comming up for me with regard to programming 4th axis CNC work. Some of the lessor packages (under 5K) only do whats called "wrapping" which requires manual unfolding in certain aspects. This will help me alot! As you know, I am new to math so when you explain "radians" I have more homework! (57.2958!)

I'v been looking at Lamina which is cool, but for some other specialized work.

I very much appreciate your time in answering these things for me that really have nothing to do with the development of MoI. I'll always try to give back somehow.
