Dimensional and Geometric Tolerances

Dimensional and geometric tolerances

Geometric dimensioning and tolerancing (GD&T, or GDT) is a symbolic method for annotating part designs, providing descriptions of the part’s size and shape along with permissible variations in manufacturing. Traditionally conveyed through 2D technical drawings, this system has evolved with the advent of modern GD&T software. Now, the information is
