You can't do that in a nurbs surface. You have to always maintain the rows 
and columns as a complete surface. Basically all nurbs surfaces are 
basically just a distorted grid. Hence if you need to make a hole you just 
use a trim curve and that just hides part of the surface.

thanks francois and simon,

i tried refine sop and it did what i want.

i also tried carve and add divisions then use skin, also achieve what i 
want.

one more question, since i'm new to using nurbs, do u think i can delete a 
primitive at nurb surface the same i did for polygon? i tried with delete 
sop seem not working, the trim sop seem to be for projecting curves onto 
surface, and not for deleting area defined by isocurves.

thanks

cheers herman

Try with the WireDeform Sop and WireCapture Sop.

But can we think it the other way. If you extract enough isoparms and do
a Skin Sop, you'll have full procedural control over the surface shape
from the curves edit with any method you like.
