Weird circular windows on a circular wall

[Phil4v]

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?

No, you did nothing wrong. The window cutout does not work on a curved wall, it will always be square.
Check this thread for a possible solution. There is another thread with a similar solution but I can't find it.

Here are more understandable pictures. The solution is to make the wall out of curves and straight sections and make it as smooth and unobtrusive as possible. In straight sections, round windows are obtained correctly. Round and straight windows can be combined to create complex openings in the walls. The wall must be very carefully made of segments, without fractures. This is the secret of success.

Yup, that's the thread I couldn't find [:)] A much better explanation of the alternative solution.
