Triangles single curved surface

Hello everyone,

I am trying to make a structure as can be seen in the image provided. So far I managed to do this with one of the index numbers. I can’t figure out how to do this with multiple index numbers because the script seems to already process the data with the multiple indices instead of picking one them and then processing the data and after that going on to the next index number.

Can someone help me in the right directions? Thanks alot!

If you internalize the data next time, you only need to share the gh file.
