Simplified Training Framework

Real-World Examples and Prints

Make Better Technical Decisions

Learning how to use geometric dimensioning and tolerancing (GD&T) shouldn’t be complicated or time-consuming. That’s why we started GD&T Basics - to give you the practical GD&T knowledge you need to design, manufacture, and inspect parts more efficiently.

Our ASME Certified instructors have trained 10,000 engineers, machinists, and production managers at the world’s leading manufacturers. Our pragmatic approach to GD&T saves clients countless hours, millions of dollars, and hundreds of headaches by preventing deviations, delays, and disputes.

Companies That Trust GD&T Basics for Training

Frustrated Engineering Student

Overwhelmed by the Complexity of GD&T Training?

  • Confused by GD&T standards and symbols?
  • Wondering, “What is GD&T, anyway, and why do I need it?”
  • Preparing for your GDTP certification exam?
  • Lacking the required GD&T experience to get a job?
  • Struggling to find GD&T training online to fit your needs?
  • Assuming that GD&T will just make your parts more complex?
  • Searching for a GD&T online course designed for the real world?

Other GD&T certification training programs teach you how to memorize the ASME Y14.5 standard, but not how to apply it to your production process. At GD&T Basics, we combine practical GD&T knowledge with real-world experience to give you a technical curriculum with practical context.

The course was extremely well-taught and made difficult concepts as easy as possible to grasp. Even after just 14 hours of this course I’m already one of the more knowledgeable people at my company with GD&T, because this course is thorough and leaves no gaping holes in knowledge. I’m looking forward to the advanced course.

Machine Shop Owner
GD&T Basics / Engineer Essentials LLC

This course offers a great overview of all the key concepts of GD&T. The course taught me several new things about conditions and cases I had never experienced or considered, and cleared up some common misconceptions I had about GD&T practices. The material is delivered at a level that is accessible to all skill levels. The course is well formatted, contains excellent graphics and animations, and provides clear explanations for tricky topics. After just a few weeks, the GD&T Basics Fundamentals course can teach you everything you need to know to read and use GD&T in a manufacturing workplace.
