Definitions:

Orientation Tolerances

The limits within which the orientation (e.g., parallelism, perpendicularity) of a part feature must lie relative to a specified datum to ensure proper assembly or function.

Perpendicularity

The condition of being exactly at 90 degrees to a given line or surface; a fundamental principle in geometric dimensioning and tolerancing.

Orientation Tolerance

Limits set on the allowable variation in the orientation (tilt or angle) of a feature on a manufactured part relative to its specified orientation.

Orientation Tolerances

Limitations placed on the angle or alignment of a feature in a technical drawing, ensuring it fits or functions as intended.
