Restricting Corridor Surfaces to EG

[chasm9a252523]

I created the assembly using two 1.8m Lane.superelevation.AOR sub-assemblies, 1.5m shoulder.vertical.sub-base sub-assembly and then Basic.SideSlope.Cut.Ditch.

Created a simple corridor using this assembly.

Set the frequency to 25.0m.

Defined target mapping (Just "Surfaces") to "EG" Surface.

Created top and bottom surfaces of the corridor with top and bottom overhangs.

Created top and bottom surface boundaries to Daylight only.

THE PROBLEM: problem is that when i draw my sections, the two corridor surfaces cross and go beyond the EG surface.

TO tackle this situation, I have to cut the both the corridor surfaces' triangles and its very tedious job. Is there any shortcut around. Like if I set the corridor's target mapping "width or offset targets" or "slope or elevation targets" to feature lines and then a feature line like daylight or which feature line will give me the intersecting surface b/w
cut n EG and
Fill n EG.
I need one single feature line.

looks like you need to extract the daylight feature line...
then use it to create a better boundary for that corridor surface
