Hi everybody-
This has happened to me in two files now. One day everything is working fine. The next day my labels on my profile view have disappeared. When I click Profile View Properties and go to the Bands tab, the data source is empty for my pipe network labels. I saw a similar post on the Autodesk Discussion Group. That solution was to reassign the surface and alignment for every pipe and structure. This didn't work for me. Another suggestion was to restart. This didn't work for me.

I thought maybe there was an issue with a pipe network and profile views created in 2013 being opened in 2014, but that doesn't seem to be it. They drawings were created in 2013 but they opened fine in 2014 and were revised, saved, and opened multiple time before they data source suddenly disappeared.

Any suggestions? Please?

Thanks so much!
