Mirrored Door Number Bug

Door schedules in Revit are great. However, if you include room numbers with your doors, you should know about a bug. Door schedules can include data from a "To Room: Number" parameter and "From Room:Number" parameter. The image below shows a simple floor plan with 5 room objects and 4 doors. Looking at a floor plan view, all the doors swing From Corridor Room Number 100 and swing into their own unique room. However, you will notice on the door schedule that Door Number 4 has the associated room parameters reversed. Why? Doors numbered 1 through 3 were placed in the model using the door command. Door swings were flipped using either the space bar or by the using the flip arrows. Door number 4 was placed using the Mirror command. Apparently, not only did Revit mirror the door, it also reversed the From Room and To Room parameters.

To correct the room parameter information, users can open the door schedule view and update the room parameters by simply selecting the correct room value for the drop down list. I should also mention that if you try to flip any of the doors so they swing into the corridor, the same room parameters in the door schedule will not update as well. The work around is the same; go to the Door Schedule view and update the parameters.
