1.0 ​Introduction Geometric Dimensioning and Tolerancing, GD&T is an international engineering language that is used on engineering drawings. It establishes a Cartesian coordinate system known as Datum Reference frame. All the dimensions and specifications are measured / referenced from this frame. GD&T uses several internationally recognized symbols with unique meaning to define products. ISO/TC 213 Dimensional and geometrical product specifications and verification. ISO/TC 213, Standardizes geometrical product specifications (GPS), i.e. macro- and microgeometry specifications covering dimensional and geometrical tolerancing. This standard covers verification principles, measuring equipment and calibration requirements. The standardization includes the basic layout and explanation of drawing indications 2.0 ​Who can attend?
