摘要： A method for checking a boundary line graph using a computing device. The computing device adds a segment line between two adjacent endpoints of the boundary line graph, if the two adjacent endpoints are not connected using the segment line. The computing device removes the segment lines of the endpoints corresponding to intersection points, if the number of the intersection points is not equal to the number of the endpoints. The computing device changes label characters of the endpoints to be arranged in a predetermined order, if an order of the label characters of the endpoints is not a predetermined order according to the boundary line vector.

摘要： In a method for simulating a measuring process of a workpiece, one or more virtual probes of a workpiece measuring machine are created. A vector of each of the virtual probes is calculated, and an appropriate vector for each of measuring points of a workpiece is acquired for a computerized drawing of the workpiece. The angle between the vector of each of the measuring points and the vector of each of the virtual probes is calculated. A virtual probe is determined for each measuring point according to the calculated angles. The measuring points are sorted according to the virtual probe of each measuring point, and the measuring programs of the sorted measuring points that relate to the same virtual probe are combined. The combined measuring programs are executed to determine whether the actual probe would collide with the workpiece.

摘要： In a method for establishing a safety plane in coordinate measurements, the method meshes a 3D model of a workpiece and a probe by triangles, and calculates a maximum bounding box of the probe. The method further obtains a moving path of the maximum bounding box after moving the maximum bounding box from a first measuring point to a second, and obtains a maximum space box of the moving path. If the maximum space box has one or more intersections with the workpiece, the method calculates a distance between vertices of each of the triangles falling within the maximum space box and a bottom face of the maximum space box, and obtains a point in the bottom face of the maximum space box that has a maximum distance from the triangles. By correcting a plane containing the point, the safety plane is obtained.

摘要： 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.
