I creating building model in openstudio with google sketchup. But when i create a surface for wall, internal wall and roof, there is no thickness for them. So i don't understand what type of surface i am creating as is it inside surface or outside surface.
It's also creating problem for window reveal surface because my window have shading of reveal surface, wall thickness is 0.8 meter and the glass is placed near the int. surface so complete wall thickness is a shading for my window but in google sketchup the window ( subsurface) and wall surface both are in same plane. So i don't understand how can i sort this problem. plz give suggestion
thank
you
