Does anyone know why if you place a duct fitting in a floor plan view it tries to host to a floor below?  The only way i can get it to host to the level is by placing it outside the building where there is no floor.  There doesn't seem to be an option to host on work plane instead of by face.  And there doesn't seem to be a way to reassociate it.  In the images attached the wye transition is fully connected to the other ductwork except that in 3D it looks wrong because it is actually hosted to a floor that is dropped 2'-0" lower below it.  Thanks in advance.

I see this pretty frequently with duct accessories like FSDs, and a similar issue when placing Mechanical Equipment or Air Terminals (and having them "stick" and "stack" in their original location when I try to copy a layout upward to different levels). The best workaround that I've found, sadly, is turning off floors and ceilings in the views that I use to build - that way, it will either host to the Level (if it's a standalone object) or to the component you're trying to host it on.

I've also seen a related issue when placing Mechanical Equipment onto a floor that sits above the associated Level. Placing the Equipment will result in all its connector handles being shifted downward by the thickness of the floor surface below.
