Task Group 142 Tolerances Practice Test

Profile of a line controls which of the following?

The shape of a line, used for edges or contours. The location of a line relative to datums. The size of a line. The orientation of a line relative to a datum.

Correct Answer:

The shape of a line, used for edges or contours.

Explanation:

The profile of a line defines the exact shape of the line’s boundary along its run, which determines the edge or contour you’re representing. It sets how the line curves or tapers along its length, not where the line is located relative to datums (that’s about position), not how long the line is (size), and not its orientation to a datum (orientation). So the profile controls the shape of the line used for edges or contours.
