The Area/Perimeter Calculator displays the area (e.g. square footage) and perimeter length of each location in your model. It also displays the total area and total perimeter (of all locations). You can use the calculator at any given point in time. The values in the calculator update automatically as your model increases or decreases in size.
Note the calculations are taken from the exterior side of the building’s walls.
