How to Create a Corridor in the Intersection Area

In this exercise, you will create a corridor using existing vertical and horizontal geometry. You will modify the corridor in the intersection area, and then experiment with the corridor region recreation tools.

Create a corridor in the intersection area

1. Open Intersection-Edit-Corridor.dwg, which is located in the tutorials drawings folder.
   This drawing contains an intersection of a primary road (Road A) and a secondary road (Road B). There currently are no corridors or corridor assemblies in the drawing.
2. Select the intersection marker.
3. Click Intersection tab Modify panel Recreate Corridor Regions  Find.
   The Intersection Corridor Regions dialog box is displayed.
4. Under Select Surface To Daylight, select Existing Ground.
5. Under Apply An Assembly Set, click Browse.
6. In the Select Assembly Set File dialog box, navigate to the Assemblies folder.
7. Select _Autodesk (Metric) Assembly Sets.xml. Click Open.
8. Click Recreate.
   A corridor is displayed in the intersection area.                                                                             Note: If the corridor is not displayed in the intersection area, you may need to rebuild the corridor. In Toolspace, on the Prospector tab, expand the Corridors collection. Right-click Corridor - (1) and click Rebuild.
