Gd T 101 An Introduction To Geometric Dimensioning And Tolerancing Geometric dimensioning and tolerancing. geometric dimensioning and tolerancing (gd&t) is a system for defining and communicating engineering tolerances via a symbolic language on engineering drawings and computer generated 3d models that describes a physical object's nominal geometry and the permissible variation thereof. Gd&t symbols reference guide from sigmetrix. in geometric dimensioning and tolerancing (gd&t), a unique set of gd&t symbols are used to define the relationships between part features and measurement references. designers and engineers utilize this international language on their drawings to accurately describe part features on the basis of size.
