Hello, I am trying to automatically add volume dampers for branch ducts and air terminals.
Did anyone try this method before?
I appreciate your help
Hi @obada try take alook at this post here, could probably give some inspiration .
I tried your script, but the problem is the duct become vertical and goes all the way down like a riser
allright did you tried Cyrils ? it works 
vertical as well, when we talk accessoires
