What is GD&T?
GD&T stands for Geometric
Dimensioning and Tolerancing, as defined by ASME Y14.5M-1994.
GD&T: An International
Geometric dimensioning and
tolerancing is an international language used on drawings to accurately
describe a part. The language consists of a well-defined set of symbols,
rules, definitions, and conventions that can be used to describe the size,
form, orientation, and location tolerances of part features.
GD&T: An Exact Language
Geometric tolerancing is
an exact language that enables designers to “say what they mean” on a drawing,
thus improving product designs. Production uses the language to interpret
the design intent, and inspection looks to the language to determine set
GD&T Provides Uniformity
By providing uniformity
in drawing specifications and interpretation, GD&T reduces controversy,
guesswork, and assumptions throughout the manufacturing and inspection
