Thanks Michael and Pilou,

I am trying to make a mobius out of a thin band of metal by modelling it I am trying to gauge the points where I can pass it through rollers to ease the grain in the metal to make the loop possible. With a paper mobius band the top and bottom edge remain same length at all times while in the cad model representation these become conical with varying tension and compression difference in the shape.

With the mobius script it also creates the shape with a series of lines which are not parallel in nature is there a way to create the mobius from a series of parallel lines which would simulate the same twist in a paper mobius as there is no deformation in that example.
