Manual Superelevation from a Civil 3D Profile

Autodesk's Alan Gilbert details a method to employ a targeted Civil 3D design Profile to generate Superelevation properties for a Corridor.

Yes, manual Superelevation design is possible in Civil 3D.
Hint - You will probably need a spreadsheet to calculate the critical Stations.
As nice as they are, Autodesk Civil 3D's supplied Superelevation Tools and catalogs do not cover all circumstances or standards.
Alan's detailed method employs a simple custom Subassembly Composer PKT to translate Profile elevation properties into Slope properties.
The PKT is then inserted before the other subassemblies.
The PKT calculated values from the elevations of a Civil 3D design profile are passed to other subassemblies via Assembly Output parameters defined in the PKT.
