Corridor section shows odd green box

[mr756944]

We have done about 5 jobs using corridors to design road widening and then do cross sections in Civil 3d. We have the latest job that is generally working well but on one section only some odd green box came up. It is tied to the corridor some how but I can't figure out why it is there. The section is using it for sizing too, which it shouldn't. I cannot find in any style which makes sense since it is NOT showing up in any other section. Any ideas?

What does that area of the corridor show in an isometric or 3D view? It may be an issue where the assemblies are not targeting the correct data at an intersection.

Ah thanks for the hint. We found an anomaly 20 or so feet away - it was an area where it didn't have a target and it was creating a cone like surface. We fixed that and the section fixed itself. Yes!

Yes! Thank you Opie.
Once we saw it in the Iso 3D view, we were able to ID the bad spot and fix it. Then the weird cross section magically fixed itself!
