I have tried using glass as material directly in the wall object, in a construction of glass-air-glass for the full area of the wall, and did not get an error. However, I did not compare the result with the normal window entry.

When I declared it as a window on a wall, I got an error that the window is too large. I reduced the 24m width by 1 cm, on one side only, and was accepted.

Windows have to be in a wall--even if the wall only is 1 mm larger.

Hi

I want to model a cube geometry which is made only from glass. So the material of the walls, and roof lets say will be glass.

If i say that the surface is Wall and give a window material then I will get an error.

I cannot model this surface as Window because i do not have a base surface (it's all the surface made by glass)

how can i model this surfaces ?

Thank you in advance
