Our Mission with GD&T

For too long, learning GD&T has been a complex mess.

Not to say that GD&T is, in itself, too overly complicated, but the way it has been taught demands that you understand every possible concept before applying it. It doesn’t help that the standard itself is written like the United States tax code – it seems overly complicated and with so much confusing content. It really is no wonder that there are a lot of designers and machine shops who just abandon the use of GD&T altogether. This is what prompted us to create GD&T Basics, as a division of our engineering training company, Engineer Essentials (formally Pareto Learning LLC).

Our goal is to be your best source for GD&T information online! It is important to us that everyone involved with engineering and machining has the chance to learn and better understand GD&T. We offer custom training solutions for both individuals and companies to help increase and clarify your knowledge of GD&T.

We strongly believe that you can learn and apply GD&T if you break the concepts down and relate them to how they are actually used in the real world – not just what is written in the standards. GD&T can be a huge benefit to those companies that adopt it. In fact, GD&T allows companies to save time, money, and headache by only focusing on what is functionally necessary for their product.

Our passion is to make GD&T approachable and understandable. After using our course material, we promise a strong foundation in your GD&T Knowledge that you can confidently apply in your work.
