How would you create a curve using more than 2 curves? Please see screenshot, there might be another way to solve the problem. Thanks!!
Hello - I am not sure I understand what you want but I think it could be that you want to make the red and blue curves follow some undulation as indicated by the wavy curves - if so, try making a
NetworkSrf from the grid of wavy curves and then
Project the red and blue onto the resulting surface.
