Learn what drives us to create the best GD&T training resources

Our History

When It All Started

Like many engineers, we learned GD&T the hard way: sitting through confusing classes that overwhelmed us with theory instead of equipping us for real-life application. We realized that GD&T training was more complex than it should be, so we designed a platform to make GD&T easy to learn and practical to use. It all started when our founder, Tom Geiss, built a website about the basics of GD&T to educate his colleagues in the automotive industry. Soon, companies across the country were asking Tom to teach engineers how to use GD&T on-the-job to solve costly manufacturing issues.

When we released the first GD&T Fundamentals online training course in January 2015, more than 125 people enrolled within the first two weeks. Since then, we’ve expanded our course offerings to enhance your engineering toolkit—launching our Advanced GD&T Course in 2018 and our Engineering Drawing Basics class in 2019. Meanwhile, we’ve broadened our training options beyond our flagship online classes to include customized corporate training, both online and onsite, in addition to public seminars.

We’ve trained nearly 10,000 engineers at hundreds of well-known companies to work with GD&T—saving our clients countless hours and millions of dollars by preventing costly deviations and disputes.

Our Vision

What We Want to Achieve

Our vision at GD&T Basics is to advance the engineering industry
by standardizing communication and promoting collaboration.

Learning to speak the language of GD&T unlocks efficiencies that can significantly reduce scrap, improve quality, and streamline production. When we all communicate clearly across every phase of design, production, and inspection, we can collaborate more effectively to improve the entire supply chain.

By providing free GD&T training resources in addition to our premium learning platform, we hope to better the whole profession. Imagine what we could engineer if we were all speaking the same language, instead of arguing over interpretations of a drawing.

Our Mission

How We’re Making a Difference

Our mission at GD&T Basics is to equip engineers with
tools to communicate confidently and skills to work productively.

Regardless of your industry, position, or experience, our training programs build the skills you need to solve complex manufacturing issues. Instead of bombarding you with confusing theories you’ll never use, we make GD&T applicable to the work you do every day.

Too many engineers stumble through their careers not knowing how to read a print, let alone communicate precise tolerancing specifications. We strive to shorten the learning curve by giving engineers the confidence and competence to speak GD&T fluently so they can produce more perfect parts.

Client Reviews

Why Clients and Students Love Us

I am a CNC Machinist /QA inspector working in the Aerospace industry. I started in the machining industry with a high school diploma. With working a lot of overtime and having a family, going to school full-time to get a degree was not suitable for me. With the GD&T Basics online courses and easy to use software I have been able to get the specialized knowledge needed to advance myself quickly as a QA inspector. I have gone from an Operator level 2 to a Machinist level 3 quicker than any of my peers and now am one of the top go-to QA inspectors for engineering in my machine shop! Thanks GD&T Basics for the great content.

Easily one of the most informative courses that I've ever taken. The lesson videos are so clean, clear and organized - simply incredible. I tried to learn GD&T by myself, but kept getting confused and overwhelmed in the concepts and symbols. I see a lot of design & manufacturing job applications require GD&T, but I was never introduced to the subject when I was still an undergraduate. However, after enrolling in this fundamentals course, I can honestly and confidently say that I understand GD&T. No doubt that this skill will make me a better Mechanical Design Engineer to my future employers!

The new webinar series is awesome - especially the clevis bracket part walk-through. It helped me understand going from standard square tolerancing to applying GD&T and how to make sense of it all. Like always, GD&T Basics (Engineer Essentials) knows how to break things down so you can understand it. They make GD&T less complicated so you’re not afraid to apply it to your designs. I think you hit a home run by adding these bonus features.

I have just finished my GD&T Basics Fundamentals course and it was a pleasure to explore this matter that permeates our daily activities in the manufacturing industry. A massive quantity of information, but very well organized. At the end there is a final exam that attests your level of understanding and makes you a better engineer. Thanks Tom Geiss and the GD&T Basics Team for putting together this amazing training.
