GD&T (Geometric Dimensioning & Tolerancing)

Duration : 12 to 14 Hrs.

Who should attend:

This Training is for Design, Manufacturing and Quality Engineers. If you are having trouble interpreting the GD&T Symbols, this course is for you. In this program we will focus on the “what, when, why and how” of GD&T. Understanding proper use of GD&T is very important as Using GD&T improperly can be worse than not using it at all.
