i guess there should be room, room separator and tag room in the room and area panel. how can i make them visible?
That looks strange. What version of Revit you are using?
Mine is Revit 2014, and it looks like this, and the panel is in the Architecture tab:
These comands are for Gross Building Area and Rentable Area calculations. The comand will be activated after you'll create an Area Plan for Gross Area or Rentable Area View...

first of all thanks for advice, i try this method but it is not handy. i wonder is there any options to come back those unseen elements
Does Revit Structure have the room tools?
I think the reason they don't appear is that either your monitor is too small, or the resolution is set too low. If you've got a widescreen monitor (like most modern monitors), then you'll see those icons by default. If you've got a low screen resolution or a 4:3 aspect ratio monitor, then you won't see them. This is hard wired to preven the buttons/icons from getting too small to be legible. If you click on the little drop down arrow on the bottom of that panel, you'll see the remainder of the tools.
the resolution is 1366x768. probably you are right. bu t i don't understand that when i click drop down arrow i just see that:
room tool still doesn't exist
