To Add Corridor Surface Boundaries

To automatically create outer boundaries

1. In the drawing, click the corridor, then right-click and click Corridor Properties.

   You can also access this functionality from the ribbon by clicking Corridor tab Modify Corridor panel Corridor Surfaces Find .

2. Click the Boundaries tab.
3. Right-click the corridor surface to which you want to add a boundary.
   • To automatically add a boundary to a corridor with a single baseline, click Add Automatically <code name>.
     Note: Only point codes that form a pair of feature lines in the corridor are listed, for example daylight and ETW.
     Note: The Add Automatically option to add boundaries Automatically is not available if more than one baseline is used in the corridor. In that case, select Corridor Extents As Outer Boundary, to automatically add a boundary for each corridor surface.
   • To automatically add a boundary to a corridor with multiple baselines, click Corridor Extents As Outer Boundary.

   The boundary is added to the corridor surface.

To interactively add a boundary to a corridor surface

1. In the drawing, click the corridor, then right-click and click Corridor Properties.

   You can also access this functionality from the ribbon by clicking Corridor tabModify Corridor panelCorridor Surfaces Find.

2. Click the Boundaries tab.
3. Right-click the corridor surface to which you want to add a boundary. Click Add Interactively.
   Note: A corridor surface must exist before you can add a corridor boundary.
4. In the drawing, click a corridor feature line that will form one side of the boundary. If you make an ambiguous selection, the Select A Feature Line dialog box is displayed. Select a feature line from the list.
5. In the drawing, click the corridor feature line that will form the other side of the boundary. If you make an ambiguous selection, the Select A Feature Line dialog box is displayed. Select a feature line from the list.
6. When you finish selecting the feature lines, press Enter.
7. In the Boundaries tab grid, expand the corridor surface to display the boundary.
8. Click Use Type. Select the type of boundary, either: Render Only, Hide Boundary, or Outside Boundary.
9. Click Apply.

To create outer boundaries using a closed polygon

1. In the drawing, click the corridor, then right-click and click Corridor Properties.

   You can also access this functionality from the ribbon by clicking Corridor tab Modify Corridor panel Corridor Surfaces Find .

2. Click the Boundaries tab.
3. Right-click the corridor surface to which you want to add a mask. Click Add From Polygon.
4. In the drawing window, click the closed polygon you want to use to define the boundaries of the corridor surface.

   The boundary is added to the corridor surface.

Note: If you create an invalid boundary, you will be prompted to continue (and correct the error), to save the invalid boundary (which can be corrected later), or to cancel the boundary creation.

To create a polyline boundary from a corridor

1. Click Home tabCreate Design panelCreate Boundary From Corridor.
2. Click a corridor in the drawing, or press Enter to select a corridor in the Select A Corridor dialog box.

   A closed polyline is created as the outer boundary of the corridor. This closed polyline can then be used to create a surface boundary, using the Add From Polygon command.
