Pick the Best GD&T Course to Boost Your Career

Stop second-guessing your drawings. Build the confidence, clarity, and real-world skill you need to get it right the first time.

Your ability to understand and communicate design intent can make or break your work in manufacturing. Without a solid grasp of GD&T, even simple prints can cause wasted time, rework, and frustration.

Our online courses cut through the confusion and focus on what actually matters on the job — how to apply GD&T to real parts, real drawings, and real problems.

Each course is built by industry experts and packed with examples, animations, and clear explanations that make even the toughest concepts click. You’ll walk away with skills you can use immediately — and confidence you can prove.

Print Reading - $199

Misreading prints leads to costly mistakes and confusion. Learn to read, interpret, and understand engineering drawings with clarity and confidence.

Our Print Reading and Tolerances course makes it easy to understand what your drawings are really telling you. We break down complex symbols, lines, and dimensioning methods into clear, practical concepts you can apply right away. Using real-world examples and shop floor context, you’ll learn how to read prints correctly, visualize parts in 3D, and communicate design intent across your team — no prior experience required.

GD&T Fundamentals - $299

Learn the practical side of GD&T — not just the symbols. Understand how to apply geometric tolerancing to real parts, drawings, and manufacturing processes.

Our GD&T Fundamentals course teaches a simple, proven framework that makes Geometric Dimensioning and Tolerancing clear and approachable. You’ll learn the essential 14 GD&T symbols, how to read feature control frames, and how datums and material conditions affect part function and inspection. This course focuses on real-world understanding, not textbook memorization — helping you read, interpret, and apply GD&T confidently across design, machining, and inspection. No prior GD&T experience required.

GD&T Inspection - $399

Bridge the gap between drawing requirements and inspection results. Learn how to apply GD&T principles to real measurement and reporting processes.

Our GD&T for Inspection course turns theoretical GD&T knowledge into hands-on inspection skill. You’ll learn how to set up parts, measure features, and report results using both manual tools and digital equipment like CMMs. This course teaches the “inspection mindset” — understanding how to simulate part datums, calculate bonus tolerance, and compare results to drawing requirements. Ideal for inspectors, machinists, and engineers who want to connect design intent to real-world measurement. (GD&T Fundamentals or equivalent experience required.)

Advanced GD&T

Take your GD&T knowledge to the next level. Learn advanced applications that improve design intent, manufacturing efficiency, and inspection accuracy.

Our Advanced GD&T course builds on the foundation from GD&T Fundamentals to give you a complete, practical understanding of how GD&T is used across complex designs and assemblies. You’ll learn about advanced datums, functional gaging, composite controls, and boundary calculations — all through real-world engineering examples. This course is ideal for engineers, designers, and inspectors ready to refine their skills, open up tolerances, and optimize designs for both performance and cost. (Included with Professional and Expert Bundles.)

This course is well-rounded, comprehensive, and taught by a great teacher. I was seeking a revision of the basics as I recently graduated and have entered the job market. To my surprise, this course offered much more than I knew about engineering drawing and provided a full perspective of how things are done in the industry. The challenging exercises and webinars are an added bonus. Definitely recommended to students, teachers, and engineers!
