Fundamentals of GD&T (The GD&T Hierarchy Coach) - 2018


Back to Computer Based Training

The GD&T Hierarchy Coach 2018 teaches Fundamentals of GD&T in accordance with the ASME Y14.5-2018 Standard with additional coverage of former practices in the ASME Y14.5M-1994 and Y14.5-2009 Standards.

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. An online final exam is available. Upon receiving a passing score, Tec-Ease will issue it's standard Certificate of Completion for The GD&T Fundamentals.

Closed Captioning is an option with this training.
