Hei!
- I need a window thught roof and ceiling to my lovely house. Whether it is called ´sunroof`? I tried to make it at flat cylinder by myself, but it looked funny, and it was not any window.[:(]

- Then I find window for my convex wall, the walls arc exent is -60, have you that kind of window?

Now I´m finding the `great-man` who helps me again.
