When It All Started
Like many engineers, we learned Geometric Dimensioning and Tolerancing 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 Print Reading and Tolerances class (formerly known as Engineering Drawing Basics) 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 over 50,000 engineers, machinists, quality techs and industrial professionals 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.
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 Geometric Dimensioning and Tolerancing 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.
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.
Our Core Values
What’s Important to Us
Even if you’re making complex parts, we believe that engineering doesn’t have to be complicated. Our purpose is to simplify the daunting world of GD&T to give engineers practical tools they can use to start making better decisions instantly.
As one of the leading GD&T training companies, we’re committed to advancing GD&T knowledge across the profession. By constantly pushing ourselves and our students to learn and grow, we are propelling the industry forward.
Our clients trust us because of our uncompromising integrity, straightforward delivery, and no-BS approach. We always do what we say we’re going to do, and we’ll never make a recommendation unless it’s in your best interest.
We’re driven by our clients’ success, because we don’t succeed unless you do. We don’t just give you enough information to pass a class—we give you a framework to solve real manufacturing problems and achieve your operational goals.
