Roundabout corridor apron missing

[francois.st-hilaire]

Hi,

I have a roundabout with an apron but the 3d corridor miss two apron part. See the two images. Any idea of why this is appening ? I am a teatcher and this problem is happening for some students only. I use Civil 3D 2018, see the image. 

Thanks !

With out the drawing file I can only make vague guesses related to missed or bad targets and C3D's dislike of closed alignments.

Oups, sorry, here it is. The two apron assembly are missing too...

AS far as I can tell there are no baselines for those two section of the apron. It is hard to tell because there seem to be duplicated base lines. Also there are 59 assemblies inserted at 0,0 all duplicates created by vehicle tracking. My guess is that multiple attempts were made to create roundabouts without deleting previous attempts has created duplicate and incomplete corridors, regions, assemblies, etc.. Try turning off all baselines in the corridor except those for the apron (I don't read French so my attempts where trial and error) and review for missing baseline and assembly.
