reviting

Hi everyone, i would like some aid about the representation of beams.
I have recently started to explore revit, having used autocad profes-sionaly for more than 8 years. I am also a archicad user, but i can tell that revit is much more a "complete" program for an engineer than other BIM software. I will post more comments in the future.
For now, my problem is with beams. In Greece we build mainly concrete structures ( columns, beams, slabs). When i draw a rectangular beam
between my columns, i can't manage it's display in plan view (as you can see what i want to do in my dwg i have uploaded).
I have tried to alter my top range view, play with the lines but nothing. The only way is to create a new reflection plan, where i can see my beams, but then i have problem with the cut range.
Any TIPS regarding beams and columns would be great.
Congratulations for reviting.net, nice job so far.
