Hi Mike,

<<I'm a bit obsessed with Moebius strips so I shall enjoy studying this simpler nod.>>

I have uploaded simpler mobius2.nod file tp previous post:

If the profile shape is even sided & the number of twists is odd (or vice versa )
the resultant form will be single-sided solid. Which is to say it could be
unrolled into a continuous looped strip.

I encourage you to indulge your obsession,
James
