GEOMETRIC DIMENSIONING & TOLERANCING (GD&T)
DVD SELF-DIRECTED TRAINING

Understanding the international engineering language of Geometric Dimensioning & Tolerancing (GD&T) is essential for communicating in today's highly competitive global marketplace. This program builds the ability to read and interpret GD&T symbols, which provide increased information about the function and relationship of part features. The critical result is the proper fit of mating parts.

Per-Use training* - This course is available on a "Per-Use" basis.
The cost for this option is $195 per person. If you would like a comprehensive Application Guide created specifically to follow along with this course, it is available for $39 (includes shipping). Also available is an Instructor’s Guide $95 (includes shipping) which includes answers to all of the problems in the student Application Guide.

This is far more than a self-study course. To get the most out of this course, an expert instructor is available for questions as you take this course, so you are definitely not on your own! After successful completion of this course, each registered student will receive an official Certificate of Completion.
