Yes, I also have problems with the beam tool. Creating a beam on the first floor should, if I select the 'show on home and floor below' option, show it dashed on the ground floor immediately below. It doesn't work - the beam shows with a solid line on the floor below and I can't find a combination that shows it otherwise.
Creating a small slab alongside the beam, and selecting the same options, creates a dashed lined slab on the floor below. That is how I want my beam to look.
Seems like a bug to me. If so, it is not a new one because I remember having the same trouble with previous versions of ArchiCad.
