Hi, I am still very new at grasshopper and am trying to figure out how to create a double curvature surface with sub-surfaces that curve the other way.
Kind of like this?
I have made the overall surface and then created panels but I am unsure of how to proceed. Any help would be greatly appreciated!

Hope you are not new on web searching 
I have exactly what you want but it’s useless for you since is 100% code. So use the attached only for fun.
Anyway the whole thing is doable with native GH components as well (maybe I’ll convert the def some day).
