1. A method of rescaling a multi-dimensional model comprises:
- retrieving, from a multi-dimensional model database, a multi-dimensional model;
identifying an architectural element located on one or more surfaces of the multi-dimensional model;
determining dimensions of the architectural element;
comparing the determined dimensions to a plurality of known similar architectural element'"'"'s standard dimensions, within an error threshold;
selecting, based on the comparing, actual dimensions of a known similar architectural element that is dimensionally closest to the architectural element;
determining an error in scaling of the multi-dimensional model based on comparing the determined dimensions to respective dimensions on the known similar architectural element; and
rescaling the multi-dimensional model according to the determined error.

Abstract
A system and method is provided for identifying error and rescaling and constructing or reconstructing a multi-dimensional (e.g., 3D building) model using known architectural dimensions. The system identifies architectural elements that have known architectural standard dimensions. Dimensional measurements of architectural elements in the multi-dimensional model (poorly scaled) are compared with known architectural standard dimensions to rescale and construct/reconstruct an accurate multi-dimensional building model.
