Geometric dimensioning and tolerancing (GD&T) is a system for defining and communicating engineering uses a symbolic language on engineering drawings and computer-generated three-dimensional solid models that explicitly describe nominal geometry and its allowable variation.
It tells the manufacturing staff and machines what degree of accuracy and precision is needed on each. GD&T has this unprecedented ability to cover almost every facet of tolerancing and this handbook especially, is the most comprehensive GD&T volume ever written by a single author.
