A perpendicularity tolerance can only constrain rotational degrees of freedom relative to the datum referenced.

Question

Quizplus · Accepted Answer

A perpendicularity tolerance specifies the allowable deviation from a perfect 90 degree angle between a referenced surface and the surface being measured. This only constrains the rotational degrees of freedom around the referenced surface, and does not constrain any other degrees of freedom, such as translational or positional.
