Hi Michael,

These curves produce a smooth single surface in Rhino as a network surface.
They do work in MoI with a 2 rail sweep and a scale rail as a polysurface, but there are some creases.

Are there a certain number of curves that work in MoI's
network surface or a particular orientation of curves that is more conducive to smooth surfaces?
Rhino has that option to sort curves by direction when they are going every which way..
I can't usually get it to work, but at least I know the direction is the problem, then. ;-)
