that was zarkow's work around because moi doesn't do n-sided patches. he did do it with surfaces in plasticity. his main end points, about 'killer features', were about this.

if you want an all nurbs comparison between the two it would have to be a lot simpler. i believe that's his whole point. plasticity just hit version 1.1. so he's progressing very fast compared to rhino and moi dev history.
