is it possible to work with polygon and nurbs the same time, so that part of the model is poly, the other part nurbs? like stitching together a poly face with a nurb. or would i go to subd, if i want both tools combined? and is subd really as good as poly and nurbs together? but maybe my biggest question is: if i can use subd, could there be any reason, not use it for learning to model? or am i only effective in subd, if i can first model poly and nurbs real good? i'm confused
