What is tolerance zone for perpendicularity in GD&T

Question

Accepted Answer

Tolerance zone for perpendicularity in GD&T is the allowable range within which a feature can deviate from being perfectly perpendicular.

Tolerance zone for perpendicularity is a 2D cylindrical tolerance zone that is perpendicular to a datum plane.
It is represented by two parallel planes that are a specified distance apart.
The feature must fall within this zone to be considered perpendicular.
The tolerance value specifies the allowable deviation from perfect perpendicularity.
For example, a perpendicularity tolerance of 0.1mm means the feature can deviate up to 0.1mm from being perfectly perpendicular.

Accepted Answer

It’s space between 2parallel lines separated by distance equal to assigned tolerance on either side of perpendicular line which is assigned with perpendicularity symbol
