How to make a surface between 3 arcs

Hi.

I seem to have a problem with making a surface between 3 arcs. What I want is to create a bridge-like form. 

But nothing I have tried so far works.

Can anybody help ?

I've attached the grasshopper file, and because my system is quite big I've written "What I need help for" so you can see where my problem is :)

Thanks in advance

Hello

The loft fails for two reasons. First is that you don not have the same data structure between the arcs you are trying to loft. Also the arcs need to be organized in a list, since loft is a single input component, one list for each set of three arcs. please check foto.

the second problem was a small one. you need to have for all the arcs the same inputs. if punkt1 is the first input of the arcs, then all the arcs need their punkt1 in order to have same direction and so that you don't get misaligned, twisted loft.

hope that helps

cheers
