I learned most of my programming from a mastercam book. I have Mastercam, the book is written by Dr. S.C Jonathon Lin, Dr F.C. tony shiue. It takes you step by step through lessens. All the little switches you can ask on this forum or programmers at work. That's how I learned. I am a programmer at work now. I will help anytime you need it and everybody in this forum will help also. Welcome to the forum.
