I’m new to grasshopper and I tried to make on surface with my curves which are frome two different lists but the option loft does’nt work. The idea is to do like on the first picture but this time with the two different curve to forme only one surface. Sorry,

I don’t know if it’s really clear.

Thanks for your help !

u need to flatten the list and weave them
