Amy - if you could post an image or two it might help determine the problem, also which version of AC are you working on? check the floor plane cut settings - in your navigator, select the problem floor, right click and go to View Settings, press the floor plan cut plane button and check the height of that - default is 1100 - this is the level at which the horizontal section that forms the floor plan is cut from, if this doesn't intersect with your doors.windows they won't show. you could also check the model view options associated with that saved view in your navigator (again, right click on the problem floor in the navigator,go to settings, check which model view option is selected) then check that the model view (Document>Model view options) being used shows the doors/windows in plan. Check under the help menu for the Reference Guide - this may help you more than my ramblings have...
