Random Daylight Cut Feature Line

[CACavallo]

For some reason I'm getting a daylight cut feature line outside my corridor which should not be there (red line).  I can't figure this one out.  My daylight fill and daylight feature lines are correct.  My cross sections through this portion of the corridor are correct too.  Any ideas?

I'll bet that you have just installed SP 2.1  Check this thread to see my screenshots of the same problem

Did uninstalling Civil 3D and reinstalling without SP 2.1 fix your problem?

I have access to another computer without the SP so I haven't tried that solution yet.

I uninstalled and reinstalled and the problem went away.  Thanks for the link to the other thread.

I solved this problem, spliting the corridor between the start and end of the random daylight feature line.

Yes, you can solve it by splitting off a new region if your corridor is finalized.  The problem is that the random feature lines appear and disappear as the corridor is edited, so you may end up with a whole lot of regions.
