What do dimension lines indicate in architectural drawings?

• A. They show altitude
• B. They denote weight
• C. They extend for length of distance being measured
• D. They indicate color

Answer: (C)

Dimension lines communicate the length of the distance between two points on the drawing. They appear as a line between two extension lines that touch the features, with arrowheads (or slashes) at each end, and a numerical value showing the measurement in the drawing’s units. This is how the exact size of features like walls, openings, or spaces is conveyed so builders know how long or wide something must be. Altitude or elevation tells you how high something sits above a base level, not how long it is. Weight describes how heavy something is, and color indicates appearance or finish, not a measured distance.
