Joining Polysurfaces - Dividing surface into tringles

Hello

Im fairly new to the grasshopper enviroment and would like to ask you guys for some help

Im working on a roof generated from a surface with some funnel shaped objetcs that intersect it. Pretty similiar to FUKSAS work on milanos exp

The thing is, my surface has several of this funnel shaped things and im not able to generate a single surface from the combination of them all. I want to do this to get a single sufrace into with then apply this triangular structure.

I really appreciate you helping me with this. Sorry for my english, again, new at this!

Kay
