You can create a surface from a corridor.
Because corridor surfaces are an output of a corridor model, they remain dynamically linked to the corridor. Any changes to the corridor definition are reflected in the surface definitions. You can also create a detached surface from a corridor surface.
You can use the Surfaces tab of the Corridor Properties dialog box to create corridor surface. Clicking Corridor Surfaces 
on the Corridors contexual ribbon tab also displays the dialog box that lets you create a corridor surface.
For information about creating a detached surface, see Exporting Corridor Surfaces.
When you create a corridor surface, it is added to the Surfaces collection on the Toolspace Prospector tab with the corridor surface icon . You can work with a corridor surface the same way you do with any surface in the Surfaces collection, including changing its style, adding labels to it, and using it for surface analysis. The following features and behaviors are unique to corridor surfaces:
- When you select a corridor surface, only the surface is selected. The corridor it is based on is not selected.
- When you change the surface style of a corridor surface using its surface properties, the style is also changed on the corridor properties Surfaces tab.
- When a corridor is rebuilt, corridor surfaces are updated to reflect any changes in the corridor, and then any edits are applied to the corridor model.
- The corridor from which the surface was taken is listed in the surface properties definition.
Tutorial Exercise: Creating Corridor Surfaces
Topics in this section
- Creating a Corridor Surface
You can create a corridor surface and then add the required feature line or link codes. Also, you can create a separate corridor surface from each link code in a single operation.
- Copying Corridor Surfaces
Create a copy of an existing corridor surface
- Editing a Corridor Surface
Modify corridor surfaces to change how they are displayed and to add or remove data from the surfaces.
- Resolving an Overhanging Surface
Correct overhanging surfaces in the corridor.
