Basic Geometric Dimensioning & Tolerancing


Industry uses GD&T to specify contractual requirements. Unfortunately, many people within industry have a flawed or incomplete understanding of the subject. Our basic course builds competence to correctly apply and interpret the rules, definitions, principles, and symbols per the American National Standard, ASME Y14.5 - 2018, in only two days! This course provides a common language to improve communication, so set-up requirements and tolerance zones are clearly understood by all.

Just think, if you fixed communication in your company, how many of your problems would go away overnight?
