Multi-dimensional model dimensioning and scale error correction
A system and method are provided for identifying scale, scale error, or improper positioning during construction or reconstruction of a multi-dimensional (e.g., 3D) building model using known architectural dimensions. The system identifies architectural elements that have known architectural standard positions relative to planes within the multi-dimensional model. Dimensional measurements of architectural elements in the multi-dimensional model (poorly scaled) are compared with known architectural standard dimensions, with or without scale error, to properly scale, rescale or position one or more planes within the multi-dimensional building model.
1. A method of correcting a multi-dimensional building model comprises:
automatically identifying an architectural element located within the multi-dimensional building model, wherein the multi-dimensional building model includes a plurality of facades, wherein each façade of the plurality of facades has been previously rectified and correlated to vertices of geometric planes that make up at least a portion of the multi-dimensional building model and wherein the architectural element is distinct from and automatically identified separately from the façade;
determining a position of the identified architectural element within the multi-dimensional building model;
identifying at least one plane within the multi-dimensional building model with a predetermined known relationship to the identified architectural element;
determining an error in position of the identified at least one plane based on a comparison of the predetermined known relationship to the identified architectural element within the multi-dimensional building model; and
moving a first position of the identified at least one plane to a second position within the multi-dimensional building model based on the determined error in position.

11. The method of claim 1 , wherein the multi-dimensional building model includes two or more identified architectural elements.
12. The method of claim 1 , wherein the error in position includes one or more dimensional errors associated with any of: width, height, length, depth, radius, diameter, circumference, or perimeter.

a processor communicatively coupled to the multi-dimensional building model database and operable to:
automatically identify an architectural element located within the multi-dimensional building model, wherein the architectural element is distinct from and automatically identified separately from the plurality of façades;

identify at least one plane within the multi-dimensional building model with a predetermined known relationship to the identified architectural element;
determine an error in position of the identified at least one plane based on a comparison of the predetermined known relationship to the identified architectural element within the multi-dimensional building model; and
