Cross-section help

[sbullinger]

I have a corridor created and a top and datum corridor surface created from that. In the cross-sections I am showing the existing ground, datum, & top surfaces. My datum is jumping around in a few spots as shown in the photo. Also my cut/fill slopes aren't stopping at my existing ground that I have set as a target surface, this isn't happenging every where just in some areas. I'm at a loss??

In your datum surface, set the overhang correction to bottom links.

Thanks Brian your the man! Any toughts on why my cut and fills aren't stopping at existing ground they seem to continue out in some areas. It looks like my surfaces go beyond the corridor boundary... I tried using the shrinkwrap boundary but it doesn't seem to do anything??

I don't know. I would have to see the file.

Hello,
I am having this same issue and was wondering if there was a solution out there. I searched the forum, found this thread, but no solution is posted. Any info would help!

I'm working in C3D 2011 and the Cuts and Fills for some sections area all messed up!

Thanks!
