  • Overview
  • Instructor


The purpose of this webinar is to introduce participants to the rules and symbols of GD&T (geometric dimensioning and tolerancing). This powerful language improves communication on mechanical drawings, and has many advantages over traditional plus/minus tolerancing.   In this webinar, participants will learn to identify, interpret, and apply the 14 geometric characteristic symbols, as well as how they relate to datums. The material is based on the ASME Y14.5-2009 technical standard. 

Who Should Attend
The webinar is intended for designers, product engineers, manufacturing engineers, manufacturing personnel, and quality/gauging inspectors, especially those who have limited or no experience with GD&T.

Included Topics:

• The traditional coordinate tolerancing system
• Why use GD&T?
• The symbol groups: form, profile, orientation, location, runout
• Reading the feature control frame
• Datums
• Maximum and least material conditions
• Bonus tolerance
• Examples
• Wrap-up

Time: 12:30 PM - 1:30 PM Eastern Time
