EDIT via MLD in the comments: In a 3D view; 1 Ensure Section box covers all elements by,Unchecking then rechecking ‘Section Box’ 2 Select some objects and the section box 3 Temporary isolate elements 4 Uncheck then recheck ‘Section Box’ again 5 Reset Temporary Hide/Isolate
Another way – is the COINS Auto-Section Box add-in available on Autodesk Exchange. Install the add-in, restart Revit, select a few objects then click the button. It will create a section box around those objects in the selected 3D view – very easy!
“the paint tool will open the Materials dialog, where now you can visually preview materials and access material properties in order to modify a material. You can see your changes without closing the Materials dialog.
Also, you can use the “Remove Paint” tool to remove a material that has been applied to a face.

EDIT In Revit 2012 and newer, the quickest way to identify paint is to use the Remove Paint tool. This does not load the Material selection panel, and will thus be faster. Also, switch 3D view to wireframe with Remove Paint to globally scan the project with your cursor for painted surfaces…
