Geometrical Dimensioning and Tolerancing (GD&T)

Geometrical Dimensioning and Tolerancing (GD&T) is a language used on mechanical engineering drawings and 3D annotated models comprising of symbols that are used to efficiently and accurately communicate geometry requirements for associated features on components and assemblies. Most engineers understand the geometric symbols, but often, true definitions are misinterpreted or inconsistently applied. Fully adopting and understanding the philosophy will enable Engineers to calculate, apply and analyse Geometrical tolerances to guarantee that parts fit together and are totally interchangeable at the design stage, before physical parts have been created.
