Hi Danny, well there are more subtle differences as well - for example in SubD modeling you don't push or pull directly on a surface like you would do with clay, you control a point cage and the surface created from that point cage is kind of shrunken and smoothed down from it.

It is a particular mechanism which works somewhat differently from clay.

Let me put it this way - an expert clay sculptor is not going to be able to sit down with a subd modeler and right away produce models with it the same as their clay sculptures. There will be a bunch of their skills on proportion and form that will certainly come over, but the medium and details of how you interact with it follows different rules in the specifics.

The subd artist needs to worry about topology, edge loops, arrangement and spacing of individual points in 3D space, these are a lot of things that don't really have a similarity in clay sculpting.

I mean don't get me wrong, I am not in any way meaning to say that the results of subd modeling are not art, just that it takes time and experience with them to really become productive and able to produce very refined and detailed shapes with them.
