The Geometric Dimensioning & Tolerancing System:It is an international language that is used on engineering drawings to accurately describe a part. The GD&T language consists of a well-defined set of symbols, rules, definitions and conventions. It is a precise mathematical language that can be used to describe the size, form, orientation, and location of part features. GD&T is also a design philosophy on how to design and dimension parts.
