I can't help with Hexagon vs Silo.. I just bought Hexagon during the DAZ sale. I've been using Carrara since before it was Carrara (RDS 5 ;*>) and love the Vertex modeller, but like some of the things I see in Hexagon. Still after a week I can't quiet get the hang of it... I can't figure how to start a model... Can't get it to stop sweeping or extruding when I want it to.. etc. Now I wonder if I wasted my money and should have started with Carrara alone! Or maybe it's just me! mike
