Rotation of windows along x, y and z axis

[JayOH]

I realise that there are a number of threads concerning rotation but I still have a dilema.

I notice that most furniture can now be rotated about x y and z. However, as far as I can see, so far, windows can only be rotated about one axis. For example an skylight cannot be angle to locate with a roof.

Is this correct or am I missing something?

Doors and windows can't be rotated around an horizontal axis. This is on purpose because Sweet Home 3D is able to make window holes only in vertical walls.
If you want care about the hole that a window could make in a slopping surface, don't import it as a door or window, or if it's already in your catalog, add it to your home, export it to OBJ format and reimport the exported OBJ file as a furniture without selecting the Door or window option in the Furniture import wizard.
If you want a hole, please reading the tip How to design a sloping ceiling with a window.
