Adding Surfaces between the lines of a grid.

Hello! First time poster here!

I am having the following problem:

> I have a somewhat complex surface 

> Diamond Panels on said surface
> Wires on the Diamond Panels
> Diamond Grid on the same surface
> connecting the horizontal vertices of the grid 
> Now i have a triangular grid made by cutting rhomboids in half.

I want to make surfaces between the lines of the newly formed grid.

Thank you!
