I tried Amapi with demo version. I had no luck to make any good model with it. I only like Carrara and ZBrush. I made alot of models with it. It is probably easier if they put some Amapi and ZBrush tools in Carrara and I might get familiar with it. Some tools in Amapi didnt make any sense to me and I had no idea what Amapi's tools I should use to make a model I want. Lathe and Vertex in Carrara is easy to make models because I can make shape with just mouse. I dont need any weird tools to manipulate with like in Amapi. ZBrush is very powerful with ZSphere and Sphere modeling with symmetery technology. ZBrush and Carrara modeling technology is almost the same in reality what people make with glass, engine, dolls, toys, etc...
