In corridor modeling, an alignment-profile pair that has an assembly attached to it is called a:

• A. Reference
• B. Centerline
• C. Anchor
• D. Baseline

Answer: (D)

Baseline is the path that carries the cross-section definition for a corridor. In Civil 3D, you pair an alignment (the horizontal path) with a profile (the vertical grade) to form a baseline, and then attach an assembly to that baseline. As you move along the baseline, Civil 3D uses the assembly to create the corridor’s cross-sections and ultimately the surface. So the alignment-profile pair with the attached assembly is called the baseline. The other terms don’t describe this exact construct in corridor modeling.
