footprint The area covered by or required by an object. For example, the footprint of a toaster on your
kitchen counter is the amount of countertop that the toaster covers.
In Revit Architecture, you can create a roof or floor based on the footprint of the walls. You can also sketch
a 2D shape to represent the desired footprint of the walls, roof, floor, or stairway of a building.
In the following image, the pink lines indicate the sketched footprint of a roof for a building. The pink
angles indicate the slope of the roof on each side.
formula A mathematical equation used to determine the dimension of an object or a calculated value for
a schedule. Formulas allow you to create parameters that depend on other parameters for their values. For
example, you can create a width parameter that equals twice the height of an object.
The following type properties include a formula for the sill length of a new window family. See Using
Formulas for Numerical Parameters on page 366.
foundation The structural base of a building that provides stability and rigidity. A wall foundation usually
rests on a footing. A slab foundation may rest directly on prepared ground.
See Wall Foundations on page 849 and Foundation Slabs on page 878.
