Sorry I'm not understanding this part... But Array Dir is about replicating one object to make multiple repeated copies of it. If I understand you correctly you do not want to do that kind of repeated duplication of one object so Array Dir will not apply to your case here.

Things like boolean intersection can generate a planar slice that is the intersection between 2 extrusions, but again I don't see how that applies to your particular situation here where you want to arrange some curves.

Did you see the method I posted above here:

Why not use that method shown there - arrange the pieces in parallel slices (either just position them with grid snap on by dragging them or use MoveSliceToPoint if you wish) and then use Flow as shown there to move them from the base line onto the curved path.
