Testimonials

"I was impressed with how thorough the tutorials were. I have been using Pro/NC for years but still learned many new techniques. 

I have taken many classes through VAR's, PTC and Rand and have never been happy with them. I always left the classes feeling as though things were missed or scanned over quickly. Before I made things work but had to do more work to get the results I wanted. 

Your tutorials covered everything and are very intuitive. Highly recommended."
