Fundamentals of GD&T personal training software based on Don Day's The GD&T Hierarchy Textbook, ASME Y14.5-2009 version with coverage of former practices in ASME Y14.5M-1994.  

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.

Closed Captioning is available.

This course should take 24 to 30 hours to complete.
