Hidden lines are represented as what style?

• A. Solid thick lines
• B. Medium weight and composed of short dashes
• C. Long dashed lines
• D. Thin continuous lines

Answer: (B)

Hidden lines indicate features that are present but not visible in the current view. They’re drawn with medium-weight lines made up of short dashes, which makes them clearly recognizable without overpowering the visible edges. This dashed pattern distinguishes them from solid, continuous lines that represent visible edges, and from other dash patterns used for different conventions. By using medium weight and short dashes, readers can infer the existence and placement of hidden features without the drawing becoming cluttered.
