Tips to create a metal perforated venetian blinds with BSDF function

Hello @mikkel,
sorry if I bring you into question, I saw that you participated in other posts on the subject, maybe you can clarify my doubts.
I spent the weekend studying the LBNL WINDOWS software but unfortunately I have not solved my problem.
Starting from the fact that this is exactly the Venetian that I should replicate
blend
I realized that even to create even a single Shading Layer (in this case perforated), I need to create a glazing system, which also contains the glazing, is that right?
After creating and calculate a Test Glazing System, no BSDF folder has been created, as the tutorial says Generating BSDF XML Files | Windows and Daylighting
w7-faq8,
for this I was stuck and I could not test a possible xml file. I don’t understand where I’m wrong, because the calculation is successful.
I wanted to ask, is this the correct procedure, even if I only want to create a perforated material containing BSDF information?
One last question, in case I would like to be even more detailed, through WINDOWS, could I insert the perforation inside a closed Venetian blind?

Hope you can help me solve this problem
Greetings
