To Edit Corridor Sections

To edit subassembly parameters in the Corridor Section Editor

1. Select a corridor in the drawing.
2. Click Corridor tabModify panelSection Editor.
3. On the Section Editor Ribbon, use the Station Selection panel to specify the station at which you want to change a parameter.
4. Do one of the following:
   • To view parameters for the entire assembly, click Section Editor tabCorridor Edit Tools panel Parameter Editor.
   • To view parameters for a single subassembly, in Section Editor, click the assembly. Hover the cursor over the appropriate subassembly grip. Click Subassembly Parameter Editor.
5. In the Corridor Parameters window, click the Value field for the parameter that you want to override. Enter a new value. When an override is applied, the Override column displays True. To remove an individual override, clear the check box next to the subassembly or parameter. To remove all overrides in an assembly, clear the checkbox in the Override column next to the assembly name.
6. To apply the override to a range of stations: On the Section Editor tab, Corridor Edit Tools panel, click Apply to a Station Range.
7. In the Apply To A Range Of Stations dialog box, enter both the start station and the end station. Click OK.
8. To view only the stations that have assembly overrides applied to them: On the Station Selection panel, next to the Select a Station list, select Overridden Stations. Only stations with assembly overrides are displayed in the list.
9. If the corridor is not set to rebuild automatically, click Update Corridor to rebuild the corridor.

Corridor surfaces and any other data that is derived from the corridor are updated using the overrides.

To add or delete points from a subassembly in the Corridor Section Editor

1. Select a corridor in the drawing.

11. If the corridor is not set to rebuild automatically, on the Corridor Edit Tools panel, click Update Corridor to rebuild the corridor. Corridor surfaces and any other data that is derived from the corridor are updated using the overrides.

To add or delete links from a subassembly in the Corridor Section Editor

1. Select a corridor in the drawing.
2. Click Corridor tabModify panelSection Editor.
3. On the Section Editor Ribbon, use the Station Selection panel to specify the station at which you want to change a parameter.
4. To add a link: On the Corridor Edit Tools drop-down, click Add Link.
5. In the drawing window, select the first point of the two points you want to connect.
   Note: You can add links only to individual subassemblies. You cannot add links that connect two subassemblies.
6. Select the second point.

   The link is added.

7. To delete a link: On the Corridor Edit Tools drop-down, click Delete Link.
8. In the drawing window, click the link you want to delete.

   The link is deleted. The points that were connected to create the link are not deleted.

9. To view only the stations that have assembly overrides applied to them: On the Station Selection panel, next to the Select a Station list, select Overridden Stations. Only stations with assembly overrides are displayed in the list.
10. If the corridor is not set to rebuild automatically, on the Corridor Edit Tools panel, click Update Corridor to rebuild the corridor. Corridor surfaces and any other data that is derived from the corridor are updated using the overrides.

To grip edit links in the Corridor Section Editor

1. Select a corridor in the drawing.
2. Click Corridor tabModify panelSection Editor.
3. On the Section Editor Ribbon, use the Station Selection panel to specify the station at which you want to change a parameter.
4. Ctrl+click a subassembly in the corridor section view.

   Grip behavior depends on the type of grip:

   Grip Type	Behavior
   Square grip at end of link	Moves the end of one of more links at this point to any point in the grid. When active, the following values are labeled: offset from baseline or controlling offset, elevation, grade, and slope.To maintain the elevation value while editing, keep the point near its original vertical location. To maintain the offset value, keep the point near the original horizontal location.
   Triangular grip at end of link	Moves the endpoint of a link while preserving the grade. When active, the following values are labeled: offset and length of link, elevation difference from original location.
   Square grip at link midpoint	Moves the link to a parallel position above or below the current position. When active, the following values are labeled: offset from baseline or controlling offset, elevation, elevation difference from original location.

5. Identify the grip you want to move, and then Ctrl+click it once to make it active.

   The grip changes color from blue to red, and the link property labels are displayed.

6. To edit a value in one of the grip labels, press Ctrl + Tab until the value you want to edit is active. Enter a new value.
7. Drag the grip to its new location, and click to place it there. The grip follows your mouse pointer, within the limits imposed by the grip type.

To insert or delete subassemblies in the Corridor Section Editor

1. Select a corridor in the drawing.
2. Click Corridor tabModify panelSection Editor.
3. On the Section Editor Ribbon, use the Station Selection panel to specify the station at which you want to change a parameter.
4. Do one of the following:
   • To view parameters for the entire assembly, click Section Editor tabCorridor Edit Tools panel Parameter Editor.
   • To view parameters for a single subassembly, in Section Editor, click the assembly. Hover the cursor over the appropriate subassembly grip. Click Subassembly Parameter Editor.
5. Select a subassembly from a tool palette in the Tool Palettes window.
6. Press Enter to create a detached subassembly.
7. To add the subassembly to the assembly: On the Corridor Edit Tools drop-down, click Add Subassembly.
8. In the drawing window, select the subassembly to which you want to attach the new subassembly.
9. To delete a subassembly: On the Corridor Edit Tools drop-down, click Delete Subassembly.
10. In the drawing window, click the subassembly you want to delete.

    The subassembly is deleted. If the deleted subassembly connected two subassemblies, they are attached to each other at the attachment point of the deleted subassembly.

11. To view only the stations that have assembly overrides applied to them: On the Station Selection panel, next to the Select a Station list, select Overridden Stations. Only stations with assembly overrides are displayed in the list.
12. If the corridor is not set to rebuild automatically, on the Corridor Edit Tools panel, click Update Corridor to rebuild the corridor. Corridor surfaces and any other data that is derived from the corridor are updated using the overrides.

You cannot undo a subassembly deletion. To rebuild the original design, insert a new instance of the subassembly or repeat the assembly selection for the region.

To edit user-defined codes in the Corridor Section Editor

1. Select a corridor in the drawing.
2. Click Corridor tabModify panelSection Editor.
3. On the Section Editor Ribbon, use the Station Selection panel to specify the station at which you want to change a parameter.
4. To edit a feature code: On the Corridor Edit Tools drop-down, click Edit User Defined Codes.
5. In the corridor section view, select a point marker, link, or shape.
6. Do one of the following:
   • Enter a new code for the feature.
   • Enter d (delete), and then click Yes to delete the user-defined codes associated with the feature.
   Note: You can only delete user-defined point, link, and shape codes. You cannot delete codes added by the subassembly macro using the Edit User Defined Code command.
7. If the corridor is not set to rebuild automatically, on the Corridor Edit Tools panel, click Update Corridor to rebuild the corridor. Corridor surfaces and any other data that is derived from the corridor are updated using the overrides.
