What type of line is used to indicate the center of a circle in blueprints?

• A. Extension
• B. Leader
• C. Object
• D. Centerline

Answer: (D)

The centerline is specifically designed to represent the center of circular features in blueprints. This line is typically depicted using a long dash followed by a short dash, which clearly indicates the axis of symmetry for circular shapes. It serves both a functional and visual purpose on technical drawings, allowing engineers and architects to easily identify the center point around which circular components are designed or measured. The use of centerlines in blueprints provides clarity in the construction and manufacturing processes, ensuring accurate placement and alignment of circular elements.
