How to Delete a Curve Set from a Superelevation Section

The simplest way to convert a curve set back to normal crown is to manually edit the superelevation control lines in the superelevation diagram. Simply right click in the superelevation diagram and select “Delete Points”.  Drag the cursor to select the points you wish to delete.  You should delete all the points that are in superelevation in the curve set you want to return normal crown.
