Correcting Ditch Location

Hello, I had created a corridor using the attached assembly with conditional cut/fill and SlopeToSurface SA, the cut condition provides a ditch SA at cut only.  Then had the Ditch Bottom Profile to follow a ditch profile that I created, and flows toward the increasing chainage.  The horizontal offset and elevation of the ditch runs perfectly fine as desired, except between Sta. 0+465 (cut section) and Sta. 0+470 (fill section), where the ditch ties back to the edge of shoulder instead of going toward the outside (as shown in the blue lines).

 

My question is, do I need to make a transition between the cut and fill sections?  If so how much effect and details is needed as I have a few other locations with the same issue.  Is there other solutions to this issue?

 

Thanks. Jacky

I'll give you a hint. The computer does not know what is going on between Sections...Right, how can it?

 

The computer only performs per the permissions and instructions that you give it. In this case, a function of your corridor frequency interval and your Ditch test points.

 

Finally, yes you have to make it work and drain. Don't leave it up to the surveyors and contractors to figure out.

Thanks, I tried using different intervals before I put up this post, didn't have any luck.  But I will take a look at the ditch test point and see if I can fix it there.
