Abstract: A computing device is connected to a measurement machine. The measurement machine measures an object to obtain images of measured elements of the object by using a measurement program. The computing device divides the measurement program into two or more program segments. An icon for each program segment is generated according to a type of the program segment.

Abstract: In a method for extracting data of a product, an electronic design document related to the product and point cloud created using actual measurements of the product are received. The point cloud includes points of the product. The method aligns the curved surface of the product with the corresponding portion of the point cloud using a best-fit method, creates a maximum space box for a feature element of the product, and deletes points that are not within the maximum space box. According to an average distance between two neighboring points of the point cloud, the maximum space box can be divided into many small space boxes. Using the small space boxes, the points are filtered to form a feature element.
