I am trying to insert a transition curve (or 'spiral' as it is named in OpenRail) BETWEEN TWO CURVES using the NSW cubic parabola type spiral in Open Rail 2021 R1. I could not use the "Spiral between elements" tool and noticed in the help file (as shown in the below snippet) that only clothoid transitions are supported by the "Spiral between elements" tool. Thus, my question is: What other means are available or suggested for inserting a cubic parabola spiral between two existing curves?
OpenRail Forum - Cubic Parabola Compound Transition - OpenRail 2021 R1
I would suggest to create a Service Request and attach your dgn and video.
There is probably a defect.
