I am trying to add contour lines to a surface at very specific elevations (rain event elevations). I can add all the intervals I want but can't seem to figure out how to add a contour at a certain elevation. Any help is greatly appreciated.
Looking for User Defined Contour. In your surface style under the display tab make sure User Defined Contour is on. Then in the surface properties, anaylsis tab, User Defined Contour from analysis type pulldown and then spedify how many contours and at what elevations.
