Lids and profile weirdness

[huesmann]

I have a channel with lidded sections that exhibits odd behavior in the profile plot view. The profile shows a line for the bottom of the lid, which is fine. However, the top of the lid seems to flip–the downstream few sections show it at the right elevation, but then it is drawn below the bottom of the lid. I’m not sure why it’s picking the elevations it’s at.

See pic, how the top of lid line crosses the bottom of lid line:

I’m guessing that for some of the cross sections, your cross section end points are higher than the lid elevation. For others, the lid is higher than the cross section end points. I don’t think this is necessarily wrong.
