{wiki=Geometric_dimensioning_and_tolerancing}
Geometric Dimensioning and Tolerancing (GD&T) is a system for defining engineering tolerances that specifies the allowable variation in a part's geometry. It provides a clear and concise way to communicate how much a feature's size, form, orientation, or location can vary from its ideal specification. GD&T is widely used in manufacturing, engineering, and design processes to ensure parts fit together properly and function as intended.
