Which statement best describes a profile of a line tolerance?

• A. It defines the boundary for the entire surface.
• B. It controls the true form of the line boundary at two ends only.
• C. It confines the true form of a line boundary along its length.
• D. It fixes the line to be perfectly straight.

Answer: (C)

A profile of a line tolerance constrains the true form of a line boundary along its length. It creates a tolerance zone that runs along the entire length of the line, so every point along that line must stay within the specified limits as you move from one end to the other. This means the line isn’t required to be perfectly straight, but any deviations along its length must stay within the tolerance band. It’s not about the boundary of an entire surface, and it isn’t limited to the ends of the line.
