Use corridor sections to examine the assemblies that make up a corridor model, as well as the surrounding civil objects, such as surfaces and pipe networks.
Sample lines are generated along a corridor's baseline alignment. Sections and section views are then created to visualize the corridor and surrounding terrain up to a specified swath width on either side of the baseline. The sections can also be used to calculate corridor material volumes.
If a sample line intersects with assemblies that are included on another baseline, then they may also be included in volume calculations that are done on the sample line group.
Depending on the angle of the sample line relative to the parent baseline, a corridor section can be displayed in either of two ways.
When the sample line is perpendicular to the parent baseline, the section reproduces the corridor assembly that is inserted the station at which the sample line intersects with the baseline.
When the sample line is not perpendicular to the parent baseline, the section samples the corridor model, creates a solid of the subassemblies that the sample line crosses, identifies features (such as links, points, and shapes) on the sliced solid, and then slices the solid to produce a sectional representation.
A corridor section may sample multiple corridor baselines. A corridor section that samples multiple baselines is created in two steps:
You can sample cross sections of complex or multiple corridors, such as intersections, 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.
Corridor shapes are used in material volume calculations. When you perform a material quantity analysis, all corridor shapes are used in the calculation.
