- Have you tried building Cul-de-sacs with the Civil 3D Corridor yet? The corridor model is very effective at modeling this geometry. I taught a basic class on this topic at Autodesk University and I can share that paper and datasets with anyone who wants to explore cul-de-sacs with the Corridor Model.
There was one problem that occurred if the alignment was curved at beginning of the cul-de-sac and you had one continuous Alignment representing the Top-of-Curb (TOC) . If you transitioned your lane from the TOC Alignment back to the CL Alignment, you would end up with a gap in the corridor. The following illustration shows what would happen.
Cul-de-sac Before SP3
The work-around was to create 2 alignments - one for the first half of the cul-de-sac and one for the second half. For SP3, we resolved this issue so now you can have one alignment representing the entire TOC.
Here is the same corridor with SP3. Very nice looking Cul-de-sac!

Have you been to http://www.dwfit.com? This is preview technology which lets you view a DWF file without installing a DWF viewer.
Here is the the Cul-de-sac DWF file hosted using the Project Freewheel technology.

Cool technology!
