displays room issues

[E.S.7.9]

hi ,

i am a new user in Revit MEP , i linked a revit file and created floor plans with copy monitor , when i click to floor plan it displays whole plan except rooms , first i thoughed that there is a problem in visibility/graphics but it`s not , because when i zoom to plan or use pan command it displays room walls  and sturcturals but when i quit of those commands it displays just grids and building main walls , the same situation as wipeout in autocad , who can show me the road about that ?

thank you

I'm not entirely following your situation here; can you post an image or two of what you are seeing?
