    Are these things always a disaster built as a corridor? I always feel there are issues when I do this. Not sure what's wrong with this corridor but we've got a million flags.

    The attached VCL should import everything

    The easiest fix is to just shorten the last segment in the alignment by 0.01 ft. (so it's not a closed alignment)

    Plan B would be to put a null template near the end of the alignment.

    Following this thread to see how this correct.  I did do a sampling distance override in the corridor template setting and had several flags get removed.  I exported the surface and reimported the surface.  Looked fine.

    roundabouts, never had issue as I closed short from the star of the alignment.  I also use 3D lines to create my corridors by means of the SIDE SLOPE tools.

    Hi Gary,

    is there any talk of having a closed alignment feature in TBC in the future? if not I would like to request it. I am constantly getting closed alignments from other packages (12d mostly) with the last elements been omitted Apon import. I spend a lot of time correcting this for roundabouts, islands, loop roads, basins and dams.

    Hey Peter,

    Supporting the closed flag on alignments from 12D is fairly near the top of our development list. Feel free to email me any sample data.
