Example: How Various Areas Are Calculated
Calculate Combined Areas
You can measure more than one area, either by specifying points or by select-
ing objects. For example, you can measure the total area of selected rooms in
a floor plan.
Subtract Areas from Combined Areas
You can subtract one or more areas from a combined area that you have
already calculated. In the example, the area of the floor plan is first
calculated, and then a room is subtracted.
