How do we know what you are going to use?

Our course development team consists of design engineers and CNC machinists who have years of experience in the automotive and fabrication industries.

We discovered that despite the differences in the fields we are in, we all focused on the same few elements of GD&T over and over. While sometimes  we came across more complex elements of GD&T in our jobs, 90% of the time we relied on the same core concepts.
