Simulating complex curved blinds

edit

Hello there

I am new to this forum and new to EnergyPlus with all its surrounding programs and possibilities. My question: is there a way to simulate blinds with complex curves, such as double curves (like a sinus) or any other curved shape? The LBNL WINDOW function to rise a blind is not enough. Does anyone know how the workflow would be to get BSDF-Data from WINDOW? Such as create geometry in CAD -> (import in THERM?) -> import in WINDOW -> export BSDF. I have only found a workflow for cellular shadings, but not for complex blinds.

From other questions I know how to import the BSDF into EP, but don't know how to get there.

Sincerely Julien
