Geometric Dimensioning & Tolerancing (GD&T) (915103)

To better define a product, geometric dimensioning and tolerancing (GD&T) is often used as a symbolic way of showing specific tolerances on drawings. GD&T is a valuable language that communicates the design intent to manufacturing and inspection. It is governed by the technical standard ASME Y14.5-2009. This course covers all aspects of GD&T. In addition to learning the theory, participants will see numerous examples that demonstrate specific applications. Participants are welcome to bring sample prints to the class for discussion or private consultation.
