Which line represents distance between two points or features?

Which line represents distance between two points or features?

• A. Center Line
• B. Object Line
• C. Dimension Line
• D. Construction Line

Answer: (C)

Dimension lines convey measurements by showing the distance between two points or features. They run between extension lines that touch the features being measured, and have arrowheads at each end with the numeric value placed near them. This setup makes it clear exactly how far apart those features are, regardless of the part’s visible outline. The center line marks the center of circles or symmetry, not a distance; object lines are the solid outlines of the part; construction lines are light, temporary guides used during drawing. So the line that represents distance between two points or features is the dimension line.
