I am trying to retrieve the FamilyInstance FacingFlipped
I have 2 cases
case 1: if the wall is drawn from left to right and we place door the face flip value I get is "False"
case 2 : if wall is drawn from right to left and we place door the face flip value i get is "True"
does door face Flip Value Depends on the start and endPoint of wall? On both cases wall is placed at top side of wall
The Orientation is based on the FamilyInstance.Orientation property - check out the original documentation here:

I assume that if the current direction is the same as the XYZ returned from this property FacingFlipped will return "true" as opposed to "false"
