hi is there a way that I can put a circular bars and longitudinal bars in a tunnel segment all at once?
what I’ve been doing lately is select the segment one by one and assign the rebars to an almost 800 tunnel segment.

It is possible, For the Circular loop Bars you can easily get the Inner and Outer Diameter Curves and offset that for Cover and use those to Create rebars.
As for the perpendicular bars, you can try rebar.FollowingSurface Node.
Maybe you could provide the Revit File.
Its not possible to incorporate rebar within any family.
hi here is the revit file link
hi thank you for your help I think I am just doing it wrong
