Is it possible to fix the size of a duct on a vertical drop as I can't physically select the duct passing between floors?
This document takes you through the process.Regards,
Thanks Duncan, This works great for the CWS sizing but can't seem to relate this to the ductwork sizing. There is no option to select "Special Height" for a duct. I am trying to drop a supply duct from the roof (1m above FFL), down into the the ceiling void of the floor below (3.5m above FFL). I have fixed the ducts on the roof to 700Wx500H, however the vertical drop between floors is being automatically sized by the programme to 1000Wx600H. I wish to fix this drop to 700Wx500H also but can't select it to do so.
Hi Chris - yes - there is no "special" option in ductwork, but there is a Duct Height option. Set this to your average duct height and you should be able to select the duct. As an alternative, you can disconnect any horizontal ducts (delete and redraw later) and use the Group Select option to fix the size.Regards,
That's done the trick now thanks for your assistance.
