![]() ![]() ![]() It is a symbolic language used on engineering drawings and computer generated 3D models to define the allowable deviation of the feature’s geometry from its nominal dimensions. GD&T stands for Geometric Dimensioning and Tolerancing - a system to define tolerances. Information on threading- internal or external, pitch, etc.,įor this purpose, GD&T is used on engineering drawings or mechanical drawings to convert it into a production drawing. The standard dimensions and number of holes (if any), the allowable amount of deviation from actual dimensions or geometry, During production, a lot of additional information needs to be given to the manufacturer. But these drawings are incomplete not very useful during the actual manufacturing of the desired part.
