In step S44, the obtaining module 210 sequentially obtains the external dimensions and materials of the selected graphic elements from the graphic database 30 .

In step S45, the search module 211 searches the standard graphic library 31 for a graphic entity whose external dimension, material and three views all match the selected graphic entity.

In step S46, the search module 211 determines whether to search for a graphic entity matching the selected graphic entity. Specifically, first, the search module 211 searches the standard graphics library 31 for graphics entities whose external dimensions and materials match those of the selected graphics entity acquired from the graphics database 30 . If there is no matching graphic element, it is judged that the search fails, and step S48 is performed; otherwise, if there is a matching graphic element, then the three-view of the selected graphic element is calculated, and the three-view of the graphic element that is found is compared with the calculation. Check whether the three views of the selected entities match.

If the comparison result matches, it is judged that the search is successful, and step S47 is performed; otherwise, if the comparison result does not match, the calculated three-view image of the selected graphic element is mirrored, and then, the image of the searched graphic element is compared again. Whether the three views match the three views after mirroring the selected entity.

If the comparison result does not match, it is judged that the search fails, and step S48 is executed; otherwise, if the comparison result matches, it is judged that the search is successful, and step S47 is executed.

The mirror image processing refers to performing a rotation operation on the three views of the selected primitive. In this embodiment, the three views of the selected graphic element refer to the front view, the right view and the bottom view.

Wherein, the step of the search module 211 calculating the three-view of the selected graphic element includes: first calculating its enclosing set according to the outline size of the selected graphic element, and then filtering the selected graphic element to filter out the selected graphic element. The drawing frame, DIM layer, geometric tolerance label and annotation text of the element, and finally offset the enclosing set of the selected entity according to the outline size of the selected entity, and obtain three offset enclosing sets, the three offset The moved bounding set is the three-view of the selected entity.

In step S47, the labeling module 212 inserts a labeling box next to the selected graphic element, and adds labeling information in the labeling box, and then executes step S49. The labeling information includes: the version number and product number of the graphic element matching the selected graphic element in the standard graphics library 31 .

In step S48, the output module 213 outputs information that the search fails, and then executes step S49.

Step S49, the search module 211 judges whether all the graphic elements selected by the user have been searched, if there are still graphic elements that have not been searched, then the flow process goes to step S44, and continues to search the standard graphics library 31 for external dimensions, materials and three-view uniformity. The primitive to match the next primitive. If all primitives have been found, the process ends.
