i have a problem with air ducts. In Autocad MEP i can select the type of ducts with or without flanges (so i can see in 3D and in 2D the dimensione of duct with flange), in Revit MEP i can't find the selection of connection between air ducts, I will see the flanges of the ducts in the drawing. It's possible?
Example of what i want have...
I believe that the flanges would have to be separate elements belonging the Duct Fittings Category, specifically with the Part Type: Union. Under the Duct's Type Properties, you can specify that as the preferring Union under Routing Preferences, and you could then use the Split command to divide the Duct segment and the flange will be automatically inserted.
