To Edit Corridor Surface Boundaries

Because boundaries are connected based on how the feature lines are selected, you can use the Corridor Boundary Definition dialog box to iteratively modify, preview, and validate the boundaries after you create them. You can:

• Add or remove feature lines from the boundary definition
• Specify if the boundary is to be drawn on a feature line in reverse of the station incrementing order.
• Change the draw order of feature lines in the boundary.
• Preview the boundary. The boundary is temporarily drawn as a green polygon.
• Ensure that the boundary is well-formed and has no crossing edges.
