    rectangular booted tee (ASHRAE SR5-13)

    I'm trying to created a rectangular booted tee (ASHRAESR5-13). When I try to connect a branch to the main and try to get thefitting to auto-place, I get a "The segment is being drawn from the wrongside to connect to the location you indicated."

    The fitting works great if I drop it in and connect ductsindividually, but I would like the auto-routing placement to work.

    Connector directions are correct.

    See the attached image of the problem and the attachedfitting.

    Any ideas?

    The orientation of the T is wrong. If you open an existing standard T you will see that the main duct goes from left to right and the T connection goes to below (Front).
    Most likely Revit is trying to place the T that way around as default, so the connection fails.

    Also, You use Global connectors instead of Fittings? Does that work reliably with auto sizing when added to a duct? (It is a solution to adding pressure drop calculations I guess)
