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, 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 are offering 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 will be able to confidently apply in your work.

Lead Course Developer and Owner of Pareto Learning LLC

I have been in the field of Automotive Engineering with several companies including BMW Manufacturing and ZF Transmissions for over 8 years and truly love it. It is fast paced and an incredible field to be in. The ability to work on something for years and then actually get to see it out on the road is very rewarding.

My love of engineering led me to study the fundamentals of what makes a good design. Throughout my entire career, I have been studying Geometric Dimensioning and Tolerancing and how it could be better applied to the automotive and mechanical fields.

It is my belief that if you want to be a great designer, you need to be an expert at GD&T. However, for too long GD&T learning has been way too complicated. The barrier to entry for learning imperative design concepts is too high. In my early years I continued to study in order to bridge the large gap between GD&T in theory and actually using GD&T in the real world. Everything came together for me when I figured out how GD&T concepts apply to real parts and their functional requirements. Years later, this prompted me to develop GD&T Basics, which explains the most important concepts and show learners how to apply what they learn in practical, real-world situations.
