Three ways I can think of off the top of my head, with pros/cons for each:
#1. Of course you can raise the Top and the Cut planes of your view range up to include the overhead beams. But then you may get other things in the view that you don't want or loose the cut through windows and doors that you do want.
#2. You can use a Plan Region to change the view range only within a certain area, in an attempt to show beams - such as for a mezzanine or similar - that doesn't go out all the way to your walls, thereby keeping your windows and doors cut properly. But this isn't going to work for ceiling beams that go all the way to the walls for obvious reasons.
#3. You can just set the view's Underlay to be the Level Above that your beams are on. But they'll be halftoned unless you turn off that Underlay setting in the Manage > Settings > Additional Settings > Halftone / Underlay settings dialog box. Doing so will effect all Underlay usage in your project.
