InDesign has a view function called Overprint Preview, with the click of a button you can view the document as it would print. This would be immensely helpful to have in Revit. I know it can be done by using "preview" from the print dialogue or by management in view templates. Those are too many extra steps, we need a way to quickly view it as it would print and then quickly turn that function off again to continue working. Ideally you could customize the settings on that button as well to say what you don't want to see such as reference planes, unplaced sections, etc.
