Hi,

I'm completely new to Sweet Home 3D, so apologize for this basic question.

When I insert a circular window on a flat (normal) wall, the 3D rendering is correct i.e the wall is around the window, but when I insert the same circular window on a circular wall then the 3D view is weird: the wall has a rectangular opening around the circular window, i.e part of the wall is missing.

Did I do something wrong?
