Civil 3D "Point not on entity"

Civil 3D "Point not on entity"

Civil 3D "Point not on entity"

(OP)
I'm creating corridors in Civil 3D and one of my corridors is giving me the error "Point not on entity" for a 150' segment of the alignment.  Does anyone know how to resolve this?

I'm using Autodesk Civil 3D 2006 version Z.77.0 with service pack HF2 on WinXP SP2.

francesca,
  If you do a Google search for "point not on entity", there is a link to an Autodesk discussion group that seems to be related to your question.

Thanks.  For posterity, the answer is:

Quote:

The no intersection message is typically displayed when the daylight link cannot find a point on the surface to attach to at the slope you specificed.
Basically if you draw a slope from the edge of the road at the slope you specified it will miss the surface.
In other words, I got that error because the fill slope extended beyond my DTM limits, which makes sense of why the error disappeared when I changed my fill slope grade.
