Like many other 3D-modeling programs, Revit allows for the design and construction of something in much less time and using fewer resources than making a physical structure.
If you were to plan a house you wanted to build, it would be easier, cheaper, and much quicker to build it on Revit than construct the entire house first. It is also invaluable if you want to change the initial design or find something does not work or is not physically possible. For example, if I wanted to change a room to be larger or found that the ceilings I planned were to short, it would be much easier to resolve in a computer program than by knocking down existing walls or an entire house.
