Abstract: Methods and systems for extracting data from a three-dimensional visual representation of a physical space, the three-dimensional visual representation of the physical space comprising either a mesh of a plurality of polygons or point cloud data points. The present method includes the steps of defining an extraction polyhedron enclosed by a boundary surface, identifying data inside the boundary surface of the extraction polyhedron for extraction, extracting the data identified inside the boundary surface of the extracting polyhedron and storing the extracted data in data storage.
