Geometric Dimensioning and Tolerancing

Geometric Dimensioning and Tolerancing

Why GD&T?

When designers apply geometric tolerancing, they must consider the fit and function of every part. GD&T, in effect, acts as a checklist for the designers to consider the dimensions of all the features. Properly applied geometric tolerance ensures that every part will assemble easily every time. Geometric tolerancing helps the designer to specify the maximum available tolerance and design the most cost-efficient parts.

What is GD&T?

Geometric dimensioning and tolerancing is an international language used on drawings to accurately describe each part. Geometric tolerancing is an exact language that enables designers to “say what they think” on a drawing, thus creating the best product designs. Providing uniformity in drawing specifications and interpretation, GD&T reduces controversy, guesswork, and assumptions throughout the manufacturing and inspection process.
