Geometric Dimensioning and Tolerancing (GD&T): Position Tolerances

GD&T position tolerances and dimensions define where features are located on a part with respect to other features. Position tolerances are typically used on holes, pins, tabs, slots, and other features of size. They are particularly useful when dealing with patterns of holes. This interactive, online course will discuss the use of GD&T for positional tolerances. It will also discuss bonus tolerance and functional gauges, as well as special considerations for positional tolerances.
