Thanks again!

Now I'm starting to understand a bit better NURBS... very well explained!
Moi is my first NURBS modeler (don't know why but I don't feel comfortable with Rhino interface). I have always used CAD, polygonal modeller (Microstation, Autocad, 3DS Max ....), so I have to "change my way of thinking".
Now I'm very happy with the program (I stop boring you so you can work on V2)
