GD&T is a system for defining and communicating engineering tolerances. This is conducted by using symbolic language from engineering drawings, which describe the nominal (theoretically perfect) geometry of controlled features. This language also communicates allowable variation in size, geometrical characteristics, and variation between features.

The Advanced GD&T course focuses on the fundamental understanding of the 14 tolerances. Practical aspects of different call-outs are discussed with the opportunity for hands-on application.
