Geometric Dimensioning and Tolerancing (GD&T) is a language used to define the size, shape, form, and orientation of physical objects. It is used to communicate engineering design intent, as well as to ensure that components are produced to the correct specifications. GD&T is based on the principles of engineering drawing, and it is used to define the relationship between the size, shape, and orientation of components and the assembly of those components.
