An integrated system generates a model of a three-dimensional object. A scanning laser device scans the three-dimensional object and generates a point cloud. The points of the point cloud each indicate a location of a corresponding point on a surface of the object. A first model is generated, responsive to the point cloud, that generates a first model representing constituent geometric shapes of the object. A data file is generated, responsive to the first model, that can be inputted to a computer-aided design system.

[ What is claimed is:] [1.]1. An integrated system for generating a model of a three-dimensional scene, comprising:a scanning laser device that scans the three dimensional scene with pulsed laser beam wherein the pulses of light last less than 1 nanosecond with up to 0.2 .mu.J in each pulse and measures the time delay, with a resolution of 30 psec or less, between each emitted pulse and a corresponding pulse that is returned from a surface of the scene and wherein said scanning laser device further tracks and measures the angular orientation of the beam during the scan; andmeans for generating a point cloud based upon the measured time delays and angle measurements, the point cloud comprising a plurality of data points that each represents a location of a corresponding point on the surface.
