Okay,
I have scoured these forums time and time again looking for an answer to this and Im finally waving my white flag.

Im looking to design a simple assembly for the attached section

2- 11' lanes with 2% cross slope with 4' soft shoulders and roadside ditches (foreslope width 11', backslope width 10') followed by a daylight to the existing surface.

I think my problem lies with the fact Im using BasicSideSlopeCutDitch and my proposed grade line is not always in the cut condition.

Ive attached screen shots of my assembly and the proposed section...

Thank you in advance.

The design of the lanes and tapered subgrade are easy, the shoulder I just created with polylines (might not be the best way to do it...) but the ditches are where I get lost.. Like I said, in the fill condition I dont have a ditch.. but for continuity of the flow from upstream I need the ditches to continue as proposed in the section below..
