Course description

Fundamentals of GD&T - Computer Based / On-Line

The GD&T Hierarchy Coach teaches Fundamentals of GD&T and is based on Don Day's popular text book, The GD&T Hierarchy. This program is in accordance with the ASME Y14.5-2009 standard with additional coverage of former practices in the ASME Y14.5M-1994.

To help make GD&T even more accessible, we have added Closed Captioning to the GD&T Hierarchy Coach.   (CC can be turned on and off)

Most programs and books on GD&T are considered dry and long. The GD&T Hierarchy Coach is not that! Tec-Ease, Inc. has worked hard in its development to help students of GD&T learn concepts the first time! It follows the same instruction technique used in Don's books, GD&T Tips and live presentations. It is geared towards many learning styles and is not only designed to assist a student in understanding GD&T concepts but also helps with information retention by providing application and inspection examples, full color 3D graphics, fun animations, quizzes and a little pointed humor.  Tec-Ease, Inc. courses earn registered continuing education credits.

This course should take 24 to 30 hours to complete.

Individual Web Access includes:

1) You take on-line so you can train anywhere

Very good presentation, clear and explained concepts.  A good course that I enjoyed and though was very relative to the work I perform.


Our instructor was confident in his knowledge of the subject, very helpful, helped us until we understood.  Great class, wouldl ike to take Applications course in the future.


Instructor was engaging, excited and could answer any question we had for him.  I hope I can take another class next year.
