Triangles Ignoring Points from Feature lines

[brendan.collum]

The Tin Triangles from one feature line are ignoring the next feature line. Even 2 points 1' apart will TIN to a different point +100' away. I have removed all surface edits except for the breaklines being added. Grading becomes a completely manual operation and exponential inflates production time. Has anyone found a solution for this persistent problem yet?

Try adding a point on the blue line where the odd jump is.

Sometimes you need to have corresponding points on the adjacent featurelines to triangulate correctly.

Usually when I see this is that someone has added a bunch of edits to the surface that is obscuring the feature lines.  Take a look at this video I did, Civil 3d My surface is ignoring the feature lines - YouTube

Thanks.

Not having the .dwg file, I can only attempt an answer. If that is a breakline running ne/sw, those long triangles could be caused by the distance between points along the polyline or feature line. 

You don't need to add additional points to the breakline objects themselves, but you should consider adding a supplementing factor to the breakline during the Add Breaklines function.
