When defining openings in a wall that include shading features (Overhangs or Sidefins) you must define the geometry of the Wall (Width and Height) as well as the geometry of the Windows and Doors (Width, Height) as well as the location of the opening on the Wall (XPos, YPos). The XPos and YPos are the position of the bottom left corner of the Window or Door on the Wall.
If the Window/Door Height + the YPos exceeds the total wall height, the surface is located out of the boundary of the Wall.
If the Window/Door Width + the XPos exceeds the total wall width, the surface is located out of the boundary of the Wall.
Check your inputs for the wall dimensions, as well as your inputs for the Window/Door dimensions as well as the relative X/Y positions for validity.
