GD & T

Geometric Dimensioning & Tolerancing

Geometric Dimensioning and Tolerancing is a language used on mechanical engineering drawings composed of symbols that are used to effeciently and accurately communicate geometry requirements for associated features on components and assemblies. GD&T has been successfully used for decades in the automotive, aerospace, and manufacturing industries. In today’s technically advanced design, engineering and manufacturing, effective and accurate communication is required to ensure successful end products.

GD&T training provides complete coverage of the fundamentals and concepts, covers how to read and interpret prints with GD&T symbols, and teaches how to draw using GD&T symbology. Based on the ASME Y14.5M-1994 standards.
