Abstract

Improper positioning of architectural features is corrected during construction or reconstruction of a multi-dimensional (e.g., 3D) building model using known architectural dimensions and known relationships to planes (facades). 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 are used to properly position one or more architectural elements relative to associated planes within the multi-dimensional building model. For example, a window position on a 3D building model first façade is moved inward (offset) according to the known relationship of a window (architectural element) being inset relative to a façade (e.g., exterior wall). In addition, a window frame could be repositioned outwardly relative to the same façade plane based on a known relationship of a frame being located on an external surface of the façade (e.g., exterior wall).

Claims

1. A method of correcting planar relationships in multi-dimensional models comprising:

identifying a representation of a first planar architectural element that is coplanar to a plane of a first faç

ade and within the first faç

ade of the multi-dimensional building model, wherein the multi-dimensional building model includes a plurality of facades;

extracting a plurality of edges of the representation of the first planar architectural element;

determining a scaling measurement for the identified first planar architectural element;

identifying an architectural dimension standard of the first planar architectural element;

determining an error in planar position of the representation of the first planar architectural element based on the architectural dimension standard and the scaling measurement;

moving the plurality of edges for the representation of the first planar architectural element relative to the first faç

ade in a translation direction and by a translation distance based on the determined error; and

reconstructing the multi-dimensional model with the representation of the first planar architectural element on an adjusted plane distinct from the plane of and offset by the translation distance to the first faç

ade and within the translated plurality of edges.

2. The method of claim 1, wherein the scaling measurement is a dimensional ratio of at least two boundaries of the plurality of boundaries for the first planar architectural element.

3. The method of claim 1, wherein the translation direction is orthogonal to an orientation of the plane.

4. The method of claim 1, wherein the multi-dimensional building model includes at least one of a two-dimensional (2D) model or a three-dimensional (3D).

5. The method of claim 1, wherein the error in planar position includes one or more dimensional errors associated with at least one of width, height, or depth.
