1. A method of scaling a multi-dimensional building model comprises: identifying an architectural element located on a plane of the multi-dimensional building model; determining one or more dimensional ratios of the identified architectural element; selecting actual dimensions of a known similar architectural element that correlate to the one or more dimensional ratios of the identified architectural element; determining a scale for the plane of the identified architectural element based on the actual dimensions; and scaling one or more planes of the multi-dimensional building model according to the determined scale.
