If our baseline was run around the cul-de-sac bulb entirely as one alignment and had as its target an centerline alighnment with an arc, the assemblies would not solve correctly and leave a flat teardrop shaped gap in the middle of the corridor. This did not happen if the centerline alignment was a tangent (straight).
The necessary workaround was to create two alignments around the bulb of the cul-de-sac each targeting the centerline alignment with the arc.
With the fix provide by Service Pack 3 we no longer need to create the two alignments and can accomplish this goal with one alignment if we so choose.
I went back through the ...README.htm file to see if this was mentioned. I could not find any mention of it. Either way this is a very good thing.
Too bad my Autodesk University "Cul-de-Sacs Are Not a Dead End" class handouts were already submitted. Oh well, I will just have to mention that that was fixed.

Thank you for posting on this! Being a somewhat new user, I always thought that I was doing something wrong with my cul-de-sac models because of that gap in my models. Then I found your post today, went back and rebuilt my corridor now that I have the new service pack and lo and behold it works perfectly! Thanks again.
