Choose from these GD&T Course Options:

Print Reading & Tolerances

Print Reading and Tolerances equips you to work with engineering drawings by breaking down their complexities into key concepts that apply to every print, using a mix of documented standards, shop floor knowledge, and real-world examples.

  • Who it's for: Absolute beginners, new hires, or anyone without formal print reading training
  • No prerequisite courses

GD&T Fundamentals

GD&T Fundamentals teaches a simple framework that allows students to understand how GD&T is used and why it improves the manufacturing process. This course is focused on practical knowledge and uses real-world examples as instructional tools.

  • Who it's for: Engineers, machinists, inspectors, or managers who need to actually use GD&T day-to-day
  • No prerequisite courses

Advanced GD&T

Advanced GD&T builds upon the GD&T Fundamentals course framework to give you a more comprehensive understanding of GD&T standards and to show how GD&T is applied for better design for manufacturability.

  • Who it's for: Design Teams and advanced inspectors who understand the basics and need to dig into complex applications
  • Prerequisites: GD&T Fundamentals

GD&T Inspection

The GD&T Inspection course provides a practical understanding of inspection considerations based on the drawing requirements. You will learn the GD&T inspection mindset - how to simulate part setups, measure parts using metrology equipment, and report inspection results.

  • Who it's for: Engineers, machinists, inspectors, or managers who need to actually use GD&T day-to-day
  • Prerequisites: GD&T Fundamentals

GD&T Design

GD&T Design bridges the gap between knowing GD&T and using it to design real parts. You’ll learn a structured approach to designing parts that assemble correctly, perform consistently, and clearly communicate intent across design, manufacturing, and inspection.

  • Who it's for: Design engineers and drafters; also beneficial for manufacturing engineers, inspectors, and anyone reviewing designs
  • Prerequisites: GD&T Fundamentals and Advanced GD&T

Why Should You Choose GD&T Basics?

Learning GD&T is easy with geometric dimensioning and tolerancing training from GD&T Basics.

Since launching our first GD&T course in 2015, we’ve trained nearly 10,000 engineers, managers, and machinists at hundreds of top companies like BMW, GE, Boeing, and NASA. Our Senior-Level ASME Certified instructors have helped our clients save countless hours and millions of dollars by preventing costly deviations and disputes with practical GD&T training. Let us be your GD&T Guide, too.

Recently, I passed the ASME GDTP Senior level exam. I got amazing help from your training course! Your lessons are great! Very easy! When I studied the ASME standard, it is just text, and text only... I only realized the true concept of each GD&T concept from your course.Thank you very much!

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.

Very step by step instructions, makes understanding GD&T quite accessible for the average person. Was able to understand the information in the format provided quite easily. Previously I had purchased a book on GD&T to get a better understanding of it, the book was not helpful as it would just state something without having explained the foundation of what it meant. Would highly recommend.
