Property Value
RoomThe "From Room" set for the door or window in the last phase of the project. if the FamilyInstance is neither a door nor a window, or if the door or window leads to a space where there is no room (an exterior space or interior space with no room defined). Also if there is no target room assigned to the last phase, or phase does not apply to this FamilyInstance.

Revit automatically calculates the "From Room" for a given door or window. This is the default shown when creating a door or window
schedule and adding the "From Room" properties. The user can opt to swap the "From Room" and "To Room" values via the schedule if they choose.
The method FlipFromToRoom also can be used to swap the values.
