Claim One:
1. A computer-implemented method for extracting data of a product using a computing device, the method comprising: receiving an electronic design document of the product, receiving a point cloud of the product created using actual measurements of the product, and a tolerance between a curved surface of the product in the electronic design document and the curved surface of the product in the point cloud, the point cloud comprising a plurality of points of the product; aligning the curved surface of the product with the corresponding portion of the point cloud using a best-fit method; creating a maximum space box for a feature element of the product by determining a maximum coordinate value and a minimum coordinate value of the feature element in an x-axis, a y-axis, and a z-axis of a coordinate system, and deleting points that are not within the maximum space box; dividing the maximum space box into a plurality of small space boxes according to an average distance between two neighboring points of the point cloud, and the maximum coordinate values and the minimum coordinate values of the feature element; obtaining points of interest that are composed of the feature element by filtering the points of the point cloud using the plurality of small space boxes, wherein the filtering uses the tolerance; and outputting the points of interest on a display device of the computing device, and drawing the feature element of the product based on the points of interest.
