SUPPLEMENTARY SYMBOLS Tail Optional) Sequence of Information in the Tail Process (as per ISO 4063) Geometric Dimensioning and Tolerancing (GDT) is a system for defining and communicating engineering tolerances. It uses a symbolic language on engineering drawings and computergenerated threedimensional solid models that explicitly describes nominal geometry and its allowable variation. It tells the manufacturing staff and machines what degree of accuracy and precision is needed on each. Dimensioning Geometrics is the science of specifying and tolerancing the shapes and locations of features on objects. Once the shape of a part is defined with an orthographic drawings, the size information is added also GDT is a system of symbols and features used in machining, manufacturing, quality and design that specify the shape, orientation, size, and critical features of the object of the drawing. GDT is used to ensure that everyone is on the same page regarding how a feature or part is defined. Geometric Dimensioning and Tolerancing (GDT) is a standard which defines and communicates mechanical tolerances by way of using symbols on engineering drawings and CAD models. It gives a detailed representation of nominal and allowable variations in geometry. Geometric Dimensioning and Tolerancing (GDT) is a language of symbols used to describe a parts nominal geometry and the allowable tolerance for variation. When applied properly the design engineer can concisely define a features location, size, shape and orientation on the part.
