Basic Applications of GD & T


Date(s) - June 18, 2019
8:00 am - 4:00 pm

EDC of Elkhart County


Geometric dimensioning and tolerancing (GD&T) is a symbolic language used on engineering drawings to specify features of a part, including the size, shape, form, and orientation. By implementing GD&T, manufacturers can more clearly and precisely define part requirements, improve inspection, gain business flexibility in today’s global economy, and save money.

This course continues to build upon the topics and concepts from the Purdue MEP workshop “An Introduction to GD&T,” which includes the history of GD&T, datums, and basic GD&T symbols. In this course, participants will obtain additional practice recognizing and interpreting basic GD&T on drawings.
