摘要： A method for processing dimension numbers using a computing device, a first template of a dimension frame and a plurality of second templates of dimension numbers 0-9, and a numerical text data of each second template are established. A plurality of block objects are obtained by grouping all discontinuous line segments in the engineering drawing. All frame objects in the engineering drawing are obtained by matching each of the block objects with the first template. One or more remainder objects in each bounding box are obtained, and grouped to obtain one or more number objects in each of the frame objects. A matched second template of each of the number objects is obtained by matching each of the number objects with each of the second templates. The number objects in each of the frame objects are replaced by corresponding numerical text data.

摘要： A method reads information of a three-dimensional (3D) product model and a light source model, and meshes the product model by multiple space triangles. The method further sets illumination parameters based on the information of product model and the light source model, simulates illuminated environment based on the illumination parameters, and projects the product model to a two-dimensional (2D) plane under the illuminated environment. 2D triangles matching the space triangles and 2D measurement points matching the 3D measurement points are determined in the 2D plane, and a measurement region is determined based on the 2D measurement points. Then, the 2D triangles in the measurement region are given colors based on illuminated effect produced by the illuminated environment, and point-selection tools are created for the 2D measurement points. At last, an off-line program is generated according to information of the measurement region and the point-selection tools.

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.
