create ETFE cushion

Hi all,

i am trying to create a numbers of etfe cushions for my project.

from the previous GH definition, i could obtain a series of planar surfaces which show the boundaries of each ETFE cushion

Then I want to use the Kangaroo example file for inflation. 

my question is:

How could I turn my planar surface to the mesh that required for inflation in this definition?

Thanks for helping!
