Sloped ceiling not working with more than one level

[mikedj]

I followed the tutorial to make a sloped ceiling (https://www.sweethome3d.com/slopingCeilingGuide.pdf), which works fine as long as I have only one level. As soon as I add a new level, the ceiling reverts to a flat ceiling at the height of the current level and no longer follows the slope of the walls.

Is this normal behavior or am I missing something?

Thank you,
Mike

Sloped ceilings are computed only at the last level.

It makes so much more sense now.

Thank you!
