I got a building, there I created one window in a south surface then i change the orientation of this and i had the next errors
** Severe ** GetSurfaces: Outward facing angle [270.0] of subsurface="WINDOWS NORTH" significantly different than
** ~~~ ** ..facing angle [0.0] of base surface=WALL NORTH Tilt=90.0
** ~~~ ** ..surface class of base surface=Wall
Does anyone know what would be the problem?, i guess is windows orientation but i have checked this but i did not see any problem.
