Geometric Dimensioning & Tolerancing Fundamentals

Geometric Dimensioning & Tolerancing

Event Start Date:

March 12, 2024

Event Start Time:

8:30 AM

Event Location:

Manufacturers Resource Center

Geometric Dimensioning & Tolerancing Fundamentals (GD&T) is a two-day workshop where participants will learn to identify, interpret, and apply the 14 geometric characteristic symbols, as well as how they relate to datums.

The purpose of this workshop is to familiarize participants with the rules and symbols of GD&T. This powerful language improves communication on mechanical drawings and has many advantages over traditional plus/minus tolerancing. The proper interpretation of GD&T callouts will be covered, and how they impact manufacturing. The material is based on the ASME Y14.5-2018 Standard.


  • Identify and explain each of the 14 GD&T symbols
  • Describe how Rule #1 controls the form of a feature
  • Interpret the feature control frame
  • Apply and interpret the MMC and LMC modifiers
  • Identify datums and explain their role in GD&T
  • Identify key changes in the 2018 standard
  • Determine proper manufacturing and gauging techniques based on the GD&T

Who Should Attend

This course is intended for CAD designers, product engineers, manufacturing engineers, Manufacturing & Quality personnel, and especially those who have limited or no experience with GD&T.
