Hi,
I like to select only the top surfaces in a list of objects. The listing of the index of the surfaces is in different orders… is there a way to select faces according to their orientation? The difficulty is also, that they are all oriented differently… so at the moment, I selected some of the top, but also some of the bottom surfaces.
Thank you!

yeah 
i was just wondering about the same thing…
but anyway… basically this is what you want to look for.
I can’t think in radians… so I convert to degree
HOWEVER there is some absolutely weird thing going on, if the first sphere is left on initial world 0,0,0
it won’t cull correctly, but IDK why:
move it off 0,0 and things work
