Corridors persist in an AutoCAD drawing as objects with the name AeccCorridor.
Corridor objects are defined by associating a baseline (alignment) with sectional design elements, and other structural data. The corridor object manages the data, tying various assemblies (applied for different ranges of stations) to the baselines (alignments) and their finished grade profiles. It manages the connection of project-specific surface and alignment data to the subassembly and assembly content. The object includes corridor body geometry, longitudinal feature lines, embedded surfaces, rendering support, and slope hatching support.
A corridor can define and display components, such as:
- Feature lines connecting points along the point codes, which are defined in the subassemblies (used to create the assemblies).
- Surfaces, using link codes and feature lines.
