Hi Pilou,

//
When you use Nurbs you know exactly the form that you want!
When you use SubD you don't know exactly the form that you will obtain! :)
it's always a surprise (good or bad :)

The problem is that most of us need to use SubD in a predictable way, where there is no room for surprise.
And the only way to archive this control is with a lot of practice (and planing) ... creating edge loop in every direction, fighting with surface distortion etc.
It's not a very funny process, at least not any more after a couple of years.

In the other hand SubDs is the only modeling technique that can tackle any subject, from organic to mechanic, and that's probably the reason its far to be 'dead' yet.

Fortunately we can now convert SudDs cage model into a Nurbs surface, and somehow take advantage of the best of those 2 modeling method.
