Use this procedure to reverse the direction of an elevation by reversing the elevation line and updating the elevation.
The direction of the elevation is determined by the direction in which you drew the elevation line. You can select the elevation line in plan view to see the bounding box that defines the area of the model included in the elevation. If the box does not include the area of the model that you intended, you can reverse the elevation line. If you have already created an elevation from the elevation line, update the elevation after reversing the elevation line.
The elevation line is mirrored about its own axis, as is the bounding box with its original parameters.
