Randomization of pannel types in revit massing


I’m doing metal cladding facade with random triangle hole system.
So, I Would like to get a dynamo script that enables the controle of hole dimension.
The aim is to get some bigger random hole on openings ( Windows).
Then, to get some smaller hole on the other part of the cladding facade.
I already made the family pattern for the revit massing, you can find it in attached document with others pictures.

I did it with curtain panel, it worked, but I got problem when I’m working in massing mode, the difficulty is to get the panel in the massing. I look in this link to get a answer but i doesn’t work:
