Building an Assembly that Supports Superelevation Axis of Rotation Pivot Points

Build assemblies for common roadway types that support superelevation axis of rotation pivot points.

This section explains only the superelevation parameters for the LaneSuperelevationAOR subassembly. It does not describe the behavior of the other potential subassemblies.

NoteDo not include an offset in an assembly that that will be used with superelevation axis of rotation. The axis of rotation calculation will not run on an assembly that contains an offset.

AutoCAD Civil 3D ships with a variety of lane subassemblies. The LaneSuperelevationAOR is the only stock lane subassembly that fully supports the axis of rotation pivot points. When you build an assembly, the following parameters must be set in a particular manner:

  • Use Superelevation
  • Slope Direction
  • Potential Pivot

When building a divided crowned roadway, the following parameters must also be set in a particular manner:

  • Inside Point Code
  • Outside Point Code

The topics in this section explain how to use these parameters in the LaneSuperelevationAOR subassembly to build common roadway types.

See LaneSuperelevationAOR for a description of the values that are available for each of these parameters.

NoteThe subassemblies that ship with AutoCAD Civil 3D vary in their ability to support superelevation axis of rotation. Subassemblies that use superelevation contain a Superelevation Axis of Rotation output parameter, which causes a warning to be issued when the LaneSuperelevationAOR subassembly is attached to it. For more information, see Superelevation Warnings and the subassembly help.
