I have been working on this problem for a couple days now and can't find a solution.
I have a rtu and 6 diffusers for a space. I am trying to use the Generate Duct feature, and it works except for the fact that it always leaves the end open and I have to stretch the main trunk and place a rectangular endcap on it to seal the system. And also the main trunk is always the same size throughout the whole length (even after using the Duct Sizing), instead of transitioning down to a smaller duct size after passing the first 2 diffusers and the next 2 diffusers.
Please see the attached pdf of my system.
The duct size should be 14x14" from the rtu, 12x12 after passing the first 2 diffusers and 10x10" after passing the next 2 diffusers.
Am I missing a setting so that Revit will make these transitions automatically when I use the Generate Duct Layout and Duct Sizing Features.
Thanks for any help.
