Surface by Sweep 3 Rails?

Hello everybody,
I am very new to Dynamo and already stuck! I am trying to create a surface from 3 curves (guidelines) and an arc (profile) but I can’t find such an option. I tried with BySweep2Rails, but as expected the surface created only takes into account 2 curves rails.
Basically I would like to add more guidelines to this type of surface creation, is it possible?
There might even be an easier way to create this kind of surface I don’t know of!
