Basic Applications of GD & T


Date(s) - May 28, 2020
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.



– Identify the 14 geometric tolerance symbols and explain what they mean.

– Explain how geometric tolerances are used in practice.

– Write and interpret GD&T symbols on drawings.

– Design a simple gauge.


Intended audience:

– Quality control/assurance technicians and inspectors; other manufacturing personnel whose jobs require the use of engineering drawings.

– Individuals who can read and interpret basic engineering prints or who have completed Purdue MEP’s workshop “Print Reading for Manufacturing.”

– Individuals who have completed Purdue MEP’s workshop “An Introduction to GD&T” or have a basic understanding of GD&T.


Registration is closed for this event.
