Calculate and edit the superelevation data to apply to roadway cross sections.
Calculate, manage, and edit superelevation data using the following:
Superelevation should be calculated before the corridor model is built along the alignment. The corridor model is not dynamic to changes in the alignment superelevation parameters. You must rebuild the corridor to include the updated superelevation.
Note: The AutoCAD Civil 3D superelevation features are used in roadway design to calculate cross slopes in a curve. In railway design, the cant features are used to calculate the amount by which rails are raised or lowered in a curve. For more information, see About Cant.
