Re-adding ducts

[david.metcalf]

I followed the lesson to add duct by creating a system to a VAV box and then creating a Mechanical System with create air supply system then edit system to add more diffusers the selected the equipment then selected a layout option, But then I needed to make some changes and deleted the duct route and attempted to recreate a replacement to no avail. the Convert button does not show up so to use the automated duct routing tool.

Seems to work with brand new "virgin" diffusers and VAV boxes.

Can any one shed light on this?

Thanks
David

I believe you have to go in and remove the equipment from the previously created air system.

OR...delete the equipment and place new and start all over.

I havent had much luck myself in editing air systems once they are created.

That's my experience too. I am sure there will be more development or information on this topic down the road.

Thanks for sharing.
