    When working in Revit MEP the transition from one duct size to another is created automatically.


    However the default transition is concentric. This is defined in the routing preferences, which can be found by selecting the duct. Then choose Edit Type

    In the dialogue box that appears select routing preferences

    Another dialogue box appear which has all of the connection settings

    The default fitting for transition is Concentric Taper. Use the load family button to import the Eccentric Taper. Once loaded it can be chosen to replace the Concentric Taper. However once applied the transition still appears concentric

    To rectify this select each duct and choose Justify on the ribbon

    The ribbon then changes to display the justify option choose the one you require.


    The ducts should now be justified correctly.

    This is very helpful, but just to note you have to align, then set your first alignment and then select your second alignment for it justify either way, but I now know! thank you.
