Duct elbows, louvers, fire dampers showing right

[shogan.198666]

Somehow I got a floor plan that is showing all duct fittings/accessories light/shaded and unselectable by crossing or window. They are there and show correctly in the section, and on the other 2 floors.
Can anyone help and tell me where I accidentally hit the wrong setting and made my Revit newbie life more difficult?

Thanks,
Sean

First thing that comes to mind is Design Options. At the bottom of the screen (next to the worksets quick select button) is the design options selector. Make sure your design option is set to the same setting as your shaded fittings.

Thx for the reply bsepter. I found out how to solve my problem. For 3RD FLOOR, in Properties>Floor Plan>Underlay my setting was incorrectly set to 3RD FLOOR. It should be 2ND FLOOR. Problem solved! (Thanks to Michael at CAD-1 Denver for solution)
