Which object defines the cross-sectional characteristics in a corridor?

• A. Corridor Assembly
• B. Alignment
• C. Profile
• D. Surface

Answer: (A)

Cross-sectional characteristics of a corridor are defined by the Corridor Assembly. The Assembly holds the templates for every part that appears in a cross-section—lanes, shoulders, curbs, medians, ditches, sidewalks, and their widths and depths. When Civil 3D creates a cross-section along the alignment, it uses the components and targets in the Assembly to shape that slice. The Alignment sets the path the corridor follows, the Profile controls how elevations change along the path, and the Surface provides the terrain context, but the actual cross-section profile comes from the Corridor Assembly.
