I’m having problems editing my pipe network in Civil 3D 2012, as you can see below some of the network parts have all the grips after editing while some of the pipes can only be edited once before I lose the grips. I have tried purge/audit, recover and the bug fix for sp1 that caused pipes to disappear. Does anyone know what might be causing my problem and if there is any way to fix it?
I don't remember exactly what the fix was but I think it had to do with the end elevations. Specifically what happened to me was, my horizontal layout changed slightly so I had to drag the pipes to match the new linework. After dragging it once I also lost the grips for the ends.
I ended up redrawing the pipes. However when I ran into this problem again, I had noticed that the elevations had gone to some ridiculous elevation of -1.52 or something. So when I edited the pipe properties and set the elevations back to what they should be, voila, pipe grips re-appeared. At least that's what I think it was that fixed the problem. It was a few months ago, and I may be remembering it poorly.
Hope that helps?!
