Summary: Add the ability to do create offset alignment transitions in spirals.
Description: I wish that Civil 3D did offset alignment transitions correctly on Spirals. I belive they fixed this issue on curves in the 2011 release, but please fix this on spirals.
How Used: To design:
-lane transitions
-barrier flares
-bus bay pullouts
This is pretty much the number one most important tool for highway design (in Canada anyway) and they didn't get it to work.
Feature Affinity: Alignments
