Hello guys, I have some issue with command “Network surface” - when I choose all the curve (instead of yellow marked on picture below) - it makes the surface with command “Network surface” - but I need to add more control curve (ass the yellow marked) for more accurate surface shape - but It cannot be done. Could someone help me, where can be trouble. I attached the file bellow.

hi @Mathew2
Network surface can only work with 2 sets of curves, where 1 set defines the U direction and the other the V direction. So your closed curves define the U direction and the open curves the V direction. The V curves need to be more or less oriented on both the U curves. In case of the curves you can’t add, one end is connected to the lower U curve, but the other end is not.
I hope the above makes sense.
So if you need more control, those two curves you added need to end at the upper U curve as well.
Thank you for your help, I will try it according to your advice 
I think it is that the Corporate version has limitations.—-Mark
