Geometric Dimensioning and Tolerancing (GD&T)

Geometric Dimensioning and Tolerancing (GD&T) is a symbolic language used in engineering and design to communicate precise specifications for the geometry and allowable variations of features in a mechanical part. It employs symbols, terms, and rules to convey information about dimensions, tolerances, and the relationship between different elements, ensuring consistent and accurate interpretation across the manufacturing and inspection processes. GD&T enhances the communication of design intent, promoting uniformity in production and facilitating the creation of functional and interchangeable components.
