Hi everybody,

I have been looking around for a while, but I did not get the point up to now.
Probably it is so easy, that no one wrote about it - but sorry I didn't get it...

I would like to create stairs between two floor levels, baselevel and basement.
How to remove the floor in the baselevel and the ceiling in the basement-level, so that in 3D-view, one is able to look up the stairs into the other floor level?

Best regards,

Jerry
