I am trying to create a surface via the box " Network Surface" on Grasshopper but I have a red flag mentionning “At least 2 curves are needed in the U direction”.
I don’t understand this problem and was not able to resolve this untill now given that I input 75 curves in the U direction of the box " Network Surface".
Do someone know how to solve this ?
I have attached the grasshopper file and a .3dm illustrating the surface that I am trying to reproduce.
Thanks for the help,
