Now that I know what it's called, I found it in the manual. However, it's not mentioned in the main "drawing walls" section; seems that it should be.

Anyway, thanks.

Can I color the walls in a given room, without the color continuing along the wall into another room?

Hello,

My house has quadrangle but non-rectangular windows (i.e. the tops slant.) It'd be great if there was a similar control to the one on walls so that I could slant them. Any workaround that enables this?

Thanks
