Geometric Dimensioning and Tolerancing

Geometric Dimensioning and Tolerancing (GD&T) is a precise engineering language used to define the allowable variations in the geometry of a part, ensuring that it meets functional requirements and fits within assembly constraints. This system utilizes symbols and annotations on technical drawings to communicate the size, shape, orientation, and location of features, facilitating clear understanding among designers, engineers, and manufacturers. By implementing GD&T, organizations can enhance product quality, reduce manufacturing costs, and streamline the design-to-production process.
