Unfortunately the only thing that works for me is to lock the layer that the labels are on before saving and closing the drawing. It will keep them how you have set them. It's annoying but it works.
Well, since you couldn't post the dwg, I created my own in 2013, SP1. All profile labels work for me, and stay upon reopening the drawing. Not sure what might be causing your issue. I'd suggest submitting a case to Adesk.
I did not create this original discussion but I have the same problem with all of my dwgs on every machine. It may have something to do with shortcuts. I tried to save a dwg to send, but when I promoted all my references, the problem went away.
Therefore, I'm attaching the problem dwg to this post and the referenced shortcut dwg in the next. If you have time please check out the attach dwgs. I'll attach the actual shortcut files in another post if necessary
Here's the referenced shortcut dwg and shortcut files - alignment & surface, respectively.
Thanks... that's what I will do. In addition, I've found that if you go into the profile properties and change the name slightly (add or take away a character) and apply, the labels reappear with customizations intact... weird
Post a screen shot of the profile label set that you'd use for this profile.
The labels are customized versions of what comes with Civ 3d. The screenshot is attached.
Thanks for your help.
Ok, not sure what to tell you. I can replicate it with your drawing and the Drefs. But... when I create a drawing with my data Dreffed into a file, label it, close, reopen, the labels are still there. I've attached a dwt (in progres) that you can use to test your data. When I did a -purge and removed the registered applications, there were 55, some I wasn't familiar with, but didn't seem to resolve the issue.
Since this system won't allow dwt files, I changed the extension to dwg.
Probably not the answer you were looking for but I was playing around with your drawings & data and can recreate several scenarios.
First, I get the same results as you when starting, with the labels disappearing.
If you synchronize the alignment the labels come back (not realistic workaround in a production environment).
It appears (IMHO) it's a timing issue where the profile view is created and labeled before it gets done synchronizing the data shortcut info.
We don't have our alignments and profiles in separate drawings, that's why we don't have this problem. I took and put them together in one drawing and DS them out to another drawing (based on your files) and they label and update correctly. Not that it helps because it might change your workflow until Autodesk fixes this but it might help shed some light on the problem.
