The below code snippet shows how to get the Superelevation transition properties from an alignment.

Example

public void SuperelevationTransitionProperties(Corridor corridor)
        {
            //Get the corridor alignment
            Bentley.CifNET.GeometryModel.SDK.Alignment alignment = corridor.CorridorAlignment;

            //Iterate for each SuperElevation Section from alignment 
            foreach (Bentley.CifNET.GeometryModel.SDK.SuperElevationSection superElevationSection 
in alignment.SuperElevationSections)
            {
                //Iterate for each SuperElevation from section
                foreach (Bentley.CifNET.GeometryModel.SDK.SuperElevation superElevation 
in superElevationSection.SuperElevations)
                {
                    //Iterate for each SuperElevationTransition from SuperElevation
                    foreach (Bentley.CifNET.GeometryModel.SDK.SuperElevationTransition 
superElevationTransition in superElevation.SuperElevationTransitions)
                    {
                        //Get transition properties 
                        Bentley.CifNET.GeometryModel.SDK.SuperElevationTransitionType transitionType = 
superElevationTransition.TransitionType;
                        double crossSlope = superElevationTransition.CrossSlope;
                        double distance = superElevationTransition.Distance;
                        string name = superElevationTransition.InternalName;
                        bool pivot = superElevationTransition.IsLeftPivot;
                        double nonLinearCurveLength = superElevationTransition.NonLinearCurveLength;
                        PivotEdgeType pivotEdgetype = superElevationTransition.PivotEdge;
                    }
                }
            }
            return;
        }

Get all SuperelevationSections from an alignment using SuperelevationSections property of Alignment. For each section get all Superelevations using SuperElevationSection.SuperElevations. superElevation.SuperElevationTransitions to get all transitions for each Superelevation.
