Thanks,

in the tutorial over roofs isnt spoken that I have to install that plugin first

I have created a roof from the pdf manual,
I cannot find the copy to furniture function...

Just exported it as 3d, then import it, everything works fine..

but when I am making picture, i have a grey sidepanel on the roof...
