being able to model have nothing to do with even art in most people's perspective =\ but i suppose the skill to model is an art of its own and not even in the same category of what we are used to as being "art"
I would have to say modeling is art, its all about the creativity. Just like makeing a sculpture, but on a computer. Just like PS is like drawing/painting.
modelling is nothing like sculpting =\ unless you're using the skulpt tool to skulpt the whole model manually which i can tell you right now that no one does, modelling is manipulating verticies, edges, polygons to look a certain way... and the last time i checked, you can't do that in skulpting =\
