Geometric Dimensioning and Tolerancing (GD&T) is a system for defining and communicating engineering tolerances. GD&T uses a symbolic language on engineering drawings and 3D solid models that explicitly describes nominal geometry and its allowable variation.
Its use saves money by:
  • Ensuring less rejections
  • Ensuring integrity of design requirement
  • Ensuring interchangeability
  • Providing uniformity in the interpretation
