Here is an example of a very detailed plan that one of our customers was gracious enough to share with us. It is the first story of a two story home with basement.

Here is the second story, with the multi-sheet option turned on (to display the first story at the same time, lightly grayed).

Here is the basement. This is where the multi-sheet option can shine - for example, you can use it to look for interferences for retrofitting ductwork, etc.
