Course Objectives

Geometric dimensioning and tolerancing (GD&T) is used as a symbolic way of showing specific tolerances on drawings. GD&T is a valuable tool that effectively communicates the design intent to manufacturing and inspection. This course introduces participants to the GD&T system, providing a working knowledge of the correct interpretation and application of each symbol, general rules, the datum system, and ‘bonus’ tolerance and highlighting some of the changes in the updated Y14.5 standard.

Participants will learn to:

  • How to interpret engineering drawings produced in accordance with the ASME Y14.5 standard.
  • How to discover the terms, rules, symbols, and concepts of GD&T as prescribed in the standard, as well as gain an in-depth understanding of the geometric symbols, including each symbol’s requirements, tolerance zones, and limitations.
  • Fundamental concepts of GD&T ensuring participant have a solid foundation for understanding more advanced topics.

Target Audience

Design, Engineering, New Product Development, Project, Manufacturing and Quality professionals new to GD&T or seeking to gain an empowering new standardised understanding of the terms, rules, symbols, and concepts of GD&T as prescribed in the ASME Y14.5M standard.
