"Ambiguous location for centering along a room edge, centering will not be done. Please click near the wall that defines the edge of the room you wish to center along."
"Items belonging to a wall can only be centered along a room edge that is parallel to the items wall."
"When centering along the edge of a room, you need to click on one or other side of the wall that defines the room edge. No centering will be done."
