Hi,

I am drawing an attic with a pitched roof.

I have designed the roof in SweetHome and saved it as object.

I then import it as object (furniture import) in the main draw of the attic and in included in the library in the category of miscellaneous objects.

Issue is that I need to rotate now ...
