What Is a Geometric Dimensioning and Tolerancing (GD&T) Drawing?
Introduction to Geometric Dimensioning and Tolerancing Geometric Dimensioning and Tolerancing (GD&T) is a symbolic language used on engineering drawings and 3D models to precisely define the allowable variation in the geometry of a part. Unlike traditional coordinate dimensioning, which specifies dimensions with plus or minus tolerances, GD&T controls the form, orientation, location, and runout of…
