GDTE is an engineering term that stands for geometric dimensioning and tolerancing. Some synonyms for GDTE include geometric tolerancing, engineering tolerances, and dimensional control. These terms refer to the set of rules and principles used in engineering to define and communicate the allowable variations in dimensions and geometric features of a product. The practice of GDTE ensures that the final product meets the required specifications and tolerances and that it functions properly. In engineering, precise communication is essential, and GDTE helps achieve this by providing a standardized way of defining and interpreting geometric specifications.
