I am trying to create cage structure used in medical inustry. In this part the i created lower body using equation driven curve and then upper body by simply move/copy bodies tool. Now the problem is, the intersection point of both bodies where i dont want the both to intersect each other. I want some twisting at curved portions of the wire so that they dont interfere. i would be very grateful if anyone could help me out in this. Attached is the part file of the part.
