Use corridor surface boundaries to prevent triangulation outside of the daylight lines of a corridor surface and prevent them from being displayed or to render an area of the corridor surface as a render material.
Corridor surfaces support the following types of boundaries:
- Render Only. Used to represent different parts of corridor surface with different materials (when rendering), for example, asphalt and grass. For more information about rendering, see Rendering Objects.
- Hide Boundary. Used to mask to create void areas or punch holes in the corridor surface. For example, if a link code Paved is used on either side of the corridor with another surface (a median), separating them, when you create a corridor surface using Paved as the data, AutoCAD Civil 3D tries to connect the gap in between two link codes. To create voids, you define boundaries to represent the surface appropriately.
- Outside Boundary. Used to define the outer boundary of the corridor surface.
Note
A corridor surface must exist before you can add a corridor boundary. For information about creating a corridor surface, see Creating and Editing Corridor Surfaces.
