Please see the screenshot below, how to generate the cut and fill slope lines when model Roads. I couldn't find a feature from the surface created by the road corridor. Thanks for your help.
Are you referring to the transverse slope lines (grey) or the green slope limit line?
I'm referring to the transverse slope lines ( grey). I could get the slope limit line ( green) from the surface feature.
I don't know if that function is in the XM version but in the V8i SS2 it's found in the menu "Drafting", "Draw Slope Direction Pattern".
