What is GD&T?

GD&T stands for Geometric Dimensioning and Tolerancing, as defined by ASME Y14.5M-1994. 

GD&T: An International Language
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 up. 

GD&T Provides Uniformity
By providing uniformity in drawing specifications and interpretation, GD&T reduces controversy, guesswork, and assumptions throughout the manufacturing and inspection process.

Effective Training Knows GD&T
ETI’s materials were developed by GD&T expert Alex Krulikowski, a recognized expert in the field of Geometric Dimensioning and Tolerancing. Alex deals with the tolerancing issues of “real world” GD&T on a daily basis, and he is a member of several national and international standards committees

With a degree in industrial vocational education and over 30 years of industry experience, Alex understands GD&T and utilizes the best teaching methods. He has written books, workbooks and software with his proven method for GD&T training, using a set of goals and objectives that keeps the training focused on the material that is most important.
