A corridor section may sample multiple corridor baselines.
A corridor section that samples multiple baselines is created in two steps:
- On the parent baseline (to which the sample line is attached), the corridor assembly that is inserted at the nearest chainage along the baseline is reproduced.
- On other subassemblies that intersect the sample line, the sample line samples each subassembly, creates a solid of the subassemblies, slices the solid to produce a sectional representation, and then identifies features (such as links, points, and shapes) on the sliced solid.
Note: On sampled assemblies that are not attached to the parent baseline, daylight links are reproduced only if the sample line is perpendicular to the assembly baseline. To view complete daylighting in a multiple baseline section, create top surfaces of all the sampled corridors, and then sample the corridor top surfaces.
You can sample cross sections of complex or multiple corridors, such as junctions, roundabouts, cul-de-sacs, off ramps, and access roads. In the following images, the corridors consist of multiple baselines. Using the sample lines shown, sections can sample any baseline that the sample lines intersect.
You can view multiple baseline corridors in the same manner using the Section Editor.
Corridor shapes are used in material volume calculations. When you perform a material quantity analysis, all corridor shapes are used in the calculation.

Use a single section to sample multiple baselines or corridors at the same time. |
