I use Amapi for mainly geometric modelling... Although it also possesses nurbs features, I tend towards Amorphium for organics. Both these apps are available in full, free versions with good value upgrades to the latest versions. Amorphium is incredibly easy to use... just pick up a tool and start prodding and pulling at the "virtual clay". Amapi (I use 4.1 at the moment) is not easy to get into in my opinion. The tutorials for the early versions are awful... some tools are not even mentioned!... suddenly it all clicked and now seems completely intuitive. I would recommend Amapi for creating poly-conservative props for Poser. And it won't leave you sobbing over your bank balance! Thats my tuppence! (Ooher Missis!) Howie:)
