argh i cannot do a really simply nurbs operation i hate the way max uses nurbs is not intuitive ( u know i' m very newbie in nurbs sigh), the question is simple (?) i have a nurbs surface (created inthe creation panel) i add a u or v curve on surface using Create U iso curve or Create V iso curve from nurbs tool panel and then all that i want to do is pick a point on the new created curve and pulling it up toward Z axis so to obtaina Hill on the flat surface, but whatever operation i do on the new create curve (make COS, Convert Curve, Make indipendent) followed by the Z rtranslating cannot obtain the surface follow the point im translating .It appear that the curve does not belong to the surface and the thing that i can only do is deleting the surface and rebuil it u-lofting the 3 (previously 2) curves ARGH please tell me there is a fastest way to do this because in more complex surfaces is very frustrating rebuilding every time the surface sigh sob

Is there a specific reason you want to use NURBS? If not, I'd leave them well alone. They're way too slow and difficult to use. As you are finding out. Patches are easier and lightning fast compared to NURBS. Or even better, use meshsmooth on editable poly.

i'm using nurbs because i need a tool that allow me to modify the final shape of an object whitout restarting it from the beginning if i make amistake or if i see at the end that a particular proportion is not good , example i make a leg whith poly at the end i see that the joint between upper and lower leg (i cant get the right word right now) is too bigger or too smaller or right/left translated , i think i can make less mess using nurbs in that case but is only a supopsition because i've started using them from few days and i'm impacting with a lot of strage way of modeling wich nurbs uses..... how u do usually modify a poly-made object when u see that it need a modification? do u go down the stackand made change? or do u use some other tool?

again thanks for the support :)

I'm not sure I understand you. Why are NURBS any better at helping you not have to start all over again?

And yeah, with editable poly, you just go to the bottom of the stack and move/scale/rotate whatever you want.

Is there any mean to post images? if i can post image it will be sompler to explain problem about easier way or not using nurbs/polys .......

ok i ve found the way to add a curve to a surcafe that belong to the surcafe and that can modify it by pulling the vertex, for anyone that is interested in:
select the sub object SURFACE and select the surface u wat to add a curve, go down the rollout until u found a list of curves that generated the surface just under the list onthe left there is a button that says REFINE unse that to add a new curve on the surface ....

Really, forget Nurbs, their a pain in the arse to model with and in max thats even more the case. Nutbs in fact are one of the worse geometry types for leading to a dead end. add to that the difficulty of merging tube shapes surfaces and you kinda get tired of them fast.
Polys are easier to work with and offer total flexibility, thats why they've become the prefered method for so many pros
