AutoCAD Civil 3D

[#1]

I am having some issues with surface profiles on a dreffed alignment no updating dynamically.

Currently it requires me to set them to static, then back to dynamic and they update.

I am well aware of the issue of dreffed surface profiles staying static. I am using the work around of dreffing in the surface and sampling in the drawing using the dreffed alignment.

Any ideas? Anyone else run into this issue?

No solution but I've seen the problem. In my experience this can be from 2 things:
1. Corruption in the dwg (can't be fixed with recover)
2. DWGs upgraded from older releases (2012 for example).

I like to make surface profiles in the same DWG as the alignment so I never have this problem.

And to contradict my earlier statements, I've tried 2012 files organized the way you do without a problem, so that's not always it.
