Getting secondary axis into dynamo with divided polycurves

Revit
1

Hi Dynamo Forum,

Before the latest update of Sofistik Bridge Modeler, I could get a secondary axis in Dynamo, which is divided with placements. It helps me to get polycurves with different distances, so I could place 3 points adaptive families and create a Tunnel. Now I only get a NurbsCurve. Could somebody help me?

thanks in advance
