Free form rebar on segment lining

Hi everyone!
I’m a new Dynamo user. I would like to apply rebars in a curved solid (segment lining of tunnels, see attachment) using free form rebar. I was able to manage it in Revit and advices tells me that “Structural Design” package could be the best one to use in Dynamo. I supposed to select one face of the segment lining, define a starting and an end point on it and then apply linear rebars considering a certain offset from the surface itself. Could it be a good way?

Thank you!

can you upload a sample model containing just the shapes you have here? I think a planar intersection with the solid might be the solution but I’d need something to test on to confirm.

Here there is the sample model

Do you have any ideas?
