Cut / Fill Lines

Is there a way to extract the cut/fill line preduced when a cut/fill map is made? I would like to use it as a linestring to create cliping boundaries.

You can use the command “Contour at elevation” then choose the cut/fill map then choose elevation “0”, you can then explode that line and use it


Or if you have RPS tools.

thank you all, i actually did use the surface interscet command it worked well
