Which blueprint element conveys the size information for features on the drawing?

• A. Dimensions
• B. Title block
• C. Notes
• D. Scale bar

Answer: (A)

Dimensions carry the size information for features on a drawing. They provide the exact numeric values—lengths, diameters, depths, radii, hole sizes, and so on—along with units and any tolerances, and they’re placed with dimension lines that tie to the feature edges or centers. This is what tells a machinist the precise sizes to manufacture. The title block holds identification and metadata about the drawing; notes give additional instructions; a scale bar shows how the drawing size relates to real size, but it does not provide the actual dimensions for each feature. So the numbers you read that specify how big or deep each feature must be come from the dimensions.
