Hi, I haven't posted here much for a while, been too busy and yes there are 2 many 3d apps to play with : ) Hexagon is a "hybrid" tool, that is a cross between nurbs surface modelling and poly modelling. It has some great features, but for me, I think it still is in its infancy yet. The main issue, for me, is that the dynamic geometry features, while they initially impressed me, are still a bit lacking in terms of a full suite of tools and options. I like the tool, but I guess I will have to hope that version 2 or 3 will really add some of the features that I think it needs to really be a solid hybrid nurbs/polygon modeller. Silo/Modo/Wings are all pure polygon modellers. They are all great and have nice functionality, but where they fall apart is their support for curves and patches. This seems to have been a trend for a while, since many 3d apps have come to the conclusion that Nurbs are dead and only have cursory support for robust curve modelling tools and nurbs. Hopefully, the hybrid approach of hexagon will take root and more will see a new way of bridging the gap so that it is easy to model polygons to curves or curves to polys, whichever the artist is more comforable with.
