1. A method of correcting incoherencies in three-dimensional (3D) building objects, comprising:

  • analyzing the 3D building object for at least one incoherent angle or plane, the analyzing including establishing main axis grouping planes as determined by one or more angular thresholds, wherein at least one of the main axis grouping planes is used to generate a weighted edge plane for each plane edge, the weighted edge plane being generated for each edge that is a distance of a new edge from an initial edge plane multiplied by a grouping normal minus the initial edge plane multiplied by a weighted edge length;

    correcting the at least one incoherent angle or plane;

    iteratively recalculating additional building angle or plane positions to support the corrected at least one incoherent angle or planes; and

    redrawing the selected 3D building object according to the recalculated building angles and plane positions.
