In drawings, a dimension value enclosed in parentheses often indicates a dimenson used for information only. What is this type called?

Explanation:
In drawings, a value placed in parentheses is an informational aid known as a reference dimension. It provides extra context or verification without being used to manufacture or inspect the part. The dimension used to actually produce and check the part is the one outside the parentheses. Reference dimensions help with interpretation and comparisons but don’t drive tolerances or fabrication.
