Go to your reference at

Surface Modeling >> NURBS >> Creating and Editing NURBS Sub-Objects >> Creating Surface Sub-Objects >> Mirror Surface

There you find a picture which has been there since Max 4.0. The head which is obviously formed by NURBS and completed by a mirror surface (see attachment).
I know 3dsmax very long now and read the reference almost every time a new version came out so I know the actual technics which are told to be used to create NURBS.
But I can just get no way to createa proper NURBS-model as the head is one. This head looks like made out of a 'grid' of splines which finally define the overlaying - and thus dependent - surface. Or am I mistaken?
There is a dozen kinds of dependent surfaces available by default but all of them seem more 'linear' and 'straight from point to point' not really usefull to create a model.

I tried that 'head-thing' myself creating a grid of NURBS-Splines welding (FUSE) the points of the different Point-Curves together but that actually does nothing - not mentioning I cannot create a overlaying dependent surface.

So finally my question is:

How can I make a head like the one I was refering to with splines and dependent surfaces?
i.e.: How can I create a surface based on a 'net' of splines?
(i.e.: How can I create a CV/Point-NURBS-Surface from scratch i.e. from different splines?)

Hope you can manage to drop me an answer - excuse my english as usual - Regards, ManDay

havent used nurbs in ages, but dont you just make your nurbs curves, then uloft or uvloft them together? check out the surfaces rollout in your curves modify panel.

Okay - so 12 minutes have passed and the textbox still hasn't turned black now - so - I'll start to type to my great notepad and will copy the text as soon as the textbox has decided to turn enabled...

I am with 3DSMax since version 4.0 and know the NURBS thing, I hope. UV Surfaces and friends are based on two or more splines which lay next to eachother (see attachment also). Not supposed to work for a grid of splines. What Program do you use? 3DSMax or something else? I cannot get rid of the feeling absolutly NOONE is actually using NURBS to model...

i suppose it depends what you are trying to model.
i tried to model a head in nurbs once, it was a pain in the ass, so i learned poly modelling and never looked back.
nurbs in max aren't highly regarded afaik.
if you're interested in poly modelling, google the 'joan of arc' tutorial.

I tried the tutorial (http://www.3dtotal.com/ffa/tutorials/max/joanofarc/body1.asp) back in a time but I got stuck at the beginning with the extrude-face thing. So I quitted...
