A math mobius has only "1 edge"

Maybe because you are trying to use your bending machine, a solution approach could be to Create the mobius curve, then "Place points" that simulate the data needed by the bender machine. Then you can export the point data and merge it into the NC file the machine is going to use to create the moves...?

Sortof an out of the box solution but should be doable. I don't know benders so am not familiar with the code generated that runs the machine so cant really get deeper...
