This section provides the process used to create and edit corridors in section view.
| Create a corridor | Specify a baseline alignment and profile, but do not create regions or specify assemblies. |
| Open the section editor | Use the section editor to view cross sections of the corridor model while either creating or editing a corridor. |
| Specify other objects to display in the section editor | Specify which Autodesk Civil 3D objects you want to represent in section. |
| Navigate to a chainage | Use the section editor tools to navigate to a corridor chainage. You can even view a section that is between corridor chainages. |
| Create a corridor region | Drag and drop an assembly from the Prospector, a Tool Palette, or a catalog, and then specify the targets and chainage range for the region. |
| Change region assemblies as desired | Specify a new region assembly either from a list, or by dragging and dropping from Prospector, a Tool Palette, or a catalog. |
