thickness	The total wall thickness
surfaceOutside	The wall net exterior surface area
surfaceInside	The wall net interior surface area
surfaceEdge	The total wall edges surface area
surfaceOutsideGross	The wall gross exterior surface area
surfaceInsideGross	The wall gross interior surface area
lengthOutside	The length along the wall exterior
lengthInside	The length along the wall interior
lengthCentre	The length along the wall centreline
doorCount	The number of doors in the wall
doorSurface	The total surface area of doors in the wall
doorWidth	The total width of doors in the wall
windowCount	The number of windows in the wall
windowSurface	The total surface area of windows in the wall
windowWidth	The total width of windows in the wall
sweep	The sweep angle a curved wall turns through – zero for straight walls
radius	The radius of a curved wall – zero for straight walls
slantInside	The interior slant angle of the wall (0 for vertical)
slantOutside	The exterior slant angle of the wall (0 for vertical)
slantAngle	Either the interior or exterior slant angle of the wall (whichever is non-vertical, in that order). Zero if both sides are vertical
