Add shading to glazing

Hi everyone,
I the geometry that I use is coming from IDF file.
I want to add shading to all the windows but when I use EPWindowShade I have an error: 1. Solution exception:‘str’ object has no attribute ‘append’.
Attached a Screenshot of my work.

Thanks !

Did you find any solution to this? I am facing the same issue

Hi vanageso,
Yes the problem is solved. I rebuild my entier buliding and it works. I don’t know the difference between the two models but it works…
