Here is a list of some of the topics involved in That reduce controversy, guesswork, and assumptions throughoutĬommunicate or interpret design requirements for suppliers andīecause GD&T is such a precise language, it involves a great many symbols and terms. How to apply and interpret GD&T correctly will help you: Quality control and inspection use the GD&T language to determine proper set-up and part verification.īy providing company-wide uniformity in the drawing specifications and interpretation, GD&T reduces controversy, guesswork, and assumptions throughout the design, manufacturing and inspection process. Process engineers and manufacturing use the language to interpret the design intent and to determine the best manufacturing approach. GD&T is an exact language that enables design engineers to 'say what they mean' on a drawing, thus improving product designs and lowering cost. It is also a design-dimensioning philosophy that encourages designers to define a part based on how it functions in the final product or assembly.

GD&T (geometric dimensioning and tolerancing) is an international language that is used on engineering drawings to accurately describe the size, form, orientation, and location of part features.
