Hi,
Earlier today I was joining some polylines and during the command AutoCAD temporarily froze. After a short time it resumed and I completed the task. However, after this some other polylines which have a thickness applied took on a 'wire-framed' appearance (see attached image where one of these lines has been selected).
Now, I've had this happen before, but always been able to easily fix it with a regen or re-launch of the file or AutoCAD itself, but now that is not working. I even rebooted my PC but this did not help.
It seems this only affects the file I was working on, an older copy of the file displays the same lines as normal.
So, has anyone encountered this and is there a 'fix'?
