Projected Tolerance Zones

Projected tolerances are specified in addition to positional tolerances to make the tolerance more specific. For example, projected tolerances specify the perpendicularity tolerance zone of an embedded part.

The symbol for projected tolerance (p) is preceded by a height value, which specifies the minimum projected tolerance zone. The projected tolerance zone height and symbol appear in a frame below the feature control frame.
