In a corridor, ______ ______ are drawn between like points along the length of a corridor.

• A. Alignment Lines
• B. Section Lines
• C. Profile Lines
• D. Feature Lines

Answer: (D)

Feature lines are three‑dimensional polylines that run along the length of a corridor by connecting corresponding points from the cross‑sections. In a corridor you often have many cross‑sections, and tying the same station points across those sections creates a continuous line that follows the corridor’s length. This makes feature lines ideal for representing longitudinal features such as edges of pavement, curb lines, or other linear grade features that extend along the entire corridor.

Section lines, by contrast, are cross‑section cuts at a station and do not run along the length; profile lines show elevations along the alignment itself rather than connecting points across sections; alignment lines aren’t a standard Civil 3D term used for this purpose.
