Geometric Dimensioning and Tolerancing (GD&T)

Geometric Dimensioning and Tolerancing (GD&T) is a system for defining and communicating engineering tolerances on technical drawings. It specifies the allowable variation in part geometry to ensure that components fit together and function correctly. GD&T uses symbols and guidelines to convey precise requirements for features like size, shape, orientation, and location. This helps manufacturers understand how much deviation is acceptable, promoting quality control and ensuring that parts work together as intended, even with slight variations in production. It is essential in fields like engineering, manufacturing, and quality assurance.
