Many design and manufacturing companies are following Geometric Dimensioning and Tolerancing (GD&T) for their production purposes, to save costs and ensure quality of products. This course will enable students to understand the GD&T system of defining and communicating explicit geometries and allowable variation (tolerances) through symbolic language on blueprints and other engineering drawings. This course is based upon ASME Y14.5-2009. This course is designed for students who already have knowledge of engineering drawings.
