Course Objectives

This program is a complete introduction to the Y14.5M-1994 and Y14.5-2009 standards. In this GD&T Training we focus on the what, when, why, and how of GD&T. The main goal of the GD&T materials is to bring all participants to a common, basic and operational level of understanding.

GD&T Fundamentals is a thorough introduction to those with a little to a moderate level of experience with GD&T.


Your drawings have GD&T symbols on them (or they should)! If you have been attempting to work with GD&T, and you lack the confidence to specify, or are having trouble interpreting the specifications, this GD&T training is for you. Using GD&T improperly can be worse than not using it at all.
