GD&T Overview

It is hard work to understand all the meanings of the GD&T symbols and regulations and correctly interpret the size tolerance (dimensional tolerance) at the same time.

Therefore, we explained GD&T in an easy-to-understand manner with a focus on interpretation and measurement. The explanation treats the ISO as the standard, and also covers how it differs from the ASME.

GD&T basics and measurement are necessary for both current and future product manufacturing.
