I don't know, all these higher end modelling apps look the same to me. It's all that 4 view thing and polygons and nurbs and sheeesh I don't think my brain can cope. On the other hand give me a physical equation to solve, a dinner to cook, and an essay to write, and I can do all three at once. Does anyone know of somewhere that gives a simple interpretation of what all these modelling types are about?. I think if I understood the components and building blocks then I could get over my mental block with modelling. Basically I need a dictionary of modelling terminology. 8) Catlin
