I received a file with a few corridors and the associated referenced files from another office. I got it all opened and everything looks like its working. I did one modification to the corridor and now the visual lines for the corridor have disappeared. I can still see my template drops and everything else. My construction elements are visible, I can find the corridor in the Project Explorer and I can still make modifications to the corridor and everything behaves as it should. I tried reprocessing the corridor and no luck (1). I know about the Corridor Reattach tool but you need a corridor to click on (2, 3). I make a point about the copied file because I never have this problem with files I create locally even when I made a new corridor in the same file that the lines disappeared in and can still see the outline of my corridor. This is not the first time it has happened as I encounter this on all externally copied files with 3D models.
I realize this has been asked before and I have searched through the following posts and tried all the suggestions.(1) https://communities.bentley.com/communities/user_communities/fdot_cadd_support/f/fdot---general-geopak/109294/corridor-lines-not-showing-still-have-my-template-drop-lines
Is there anyway to get the corridors to show up again?
It sounds simple, but have you tried reactivating the main corridor profile and/or terrain? A corridor association may have been lost. The keyin "Civil Display Browser" may help repair these links -- Click "repair relationships". If this doesn't work in the current version of the file, try reopening the files you were sent before changes and run the tool.
I reactivated the terrain and profile, no luck. I got this error when I did the repair relationships even on the original.
Can you verify the profile assigned to the corridors exist? Use the context sensitive popup menu to change from "active" profile to a specific profile you can verify. I've had this happen before and there seems to be no redemption once it happens, however taking a previous backup through trial and error will do the trick eventually. Unlock rule on the corridor from the start and try to relink what you can- locking/process it one change at a time... rinse and repeat to find what's causing it.
