“Excellent refresher course, good for our whole department regardless of skill level or experience.” – Kevin, Utah

“It was a good primer on the fundamentals of GD&T. It makes much more sense now.” – Christopher, Minnesota

“Good base understanding of a critical design language all design/engineering/manufacturing/quoting/quality professionals should know.” – Brandon, Minnesota

“This GD&T course opened my eyes to a whole another level of inspection methods.” – Rick, Minnesota

“I learned more in this course about GD&T than I did in college.” – Jonathan, Wisconsin

Target Audience

This workshop is designed for anyone involved in part manufacturing from design through to inspection. It can benefit engineers, technicians, quality personnel, and anyone who has a need to understand, define and/or communicate tolerances on engineering drawings.


A working understanding of technical drawings (perspectives, sections, details, etc.).  Blueprint Reading for Industry is suggested.

Course Objectives

This program is a complete introduction to the Y14.5M-1994, Y14.5-2009, and Y14.5-2018 standards. The gap between designers and measurement personnel is closed. The concepts are introduced to both groups, from two different angles. Design and Inspection techniques are examined that will greatly increase knowledge of inspection methods.


This workshop will teach the fundamental aspects of GD&T to help the student understand and communicate the design intent of a part. In this technically advanced manufacturing world, this is vital to a successfully designed and manufactured product.

What is the difference between this 2-day class and our 3-day class?  In both offerings the student is trained in important dimensioning concepts.  However, the primary difference is the 3-day class affords the student opportunity to cover each topic in more depth with more hands-on application.


  1. Basic Principles and Definitions
  2. Rules and Advanced Concepts
  3. Datums and Datum Reference Frames
  4. Tolerances of Form
  5. Tolerances of Orientation
  6. Tolerances of Location
  7. Tolerances of Profile
  8. Tolerances of Runout
