The order of the steps in the flow chart may be changed and some steps may be omitted according to different needs. For convenience of explanation, only relevant portions of the embodiments of the present application are shown.
The 3D non-geometric information conversion method comprises the following steps:
and step S11, acquiring the three-dimensional product object in the CAD software.
It should be noted that the three-dimensional product object may be a design drawing formed in the CAD software, and includes geometric topological information and non-geometric information, where the geometric topological information may be graphical information on the three-dimensional product object, and the non-geometric information is non-graphical information including dimensions, comments, technical instructions, and the like on the three-dimensional product object.

Reading the three-dimensional product object based on the codes, colors or topological properties on the geometric topological information and the non-geometric information on the three-dimensional product object.
Illustratively, if the rule is color, and it is assumed that the geometric topological information is a rectangle, the color of the rectangle is red, the non-geometric information on the rectangle is size information, and the size information is blue, the reading is performed based on the red on the rectangle and the blue of the size information.

Specifically, the marking is to mark geometric topological information and non-geometric information, and may be performed according to coding, color or topological attribute characteristics, so as to establish a corresponding relationship between the geometric topological information and the non-geometric information.
For example, if the marking is performed according to the color, the geometric topological information is marked as red if the read geometric topological information is red, the non-geometric information is marked as blue if the non-geometric information on the read geometric topological information is blue, the geometric topological information is marked as red and the non-geometric information is marked as blue, and the corresponding relationship between the geometric topological information and the non-geometric information is realized according to the corresponding relationship between the red and the blue.
Step S15, converting the marked non-geometric information into a data set with a preset format;
in one embodiment, the predetermined format of the data set is an XML (Extensible Markup Language), and it is understood that other forms of XML may be used as the predetermined format. In this step, the preset format is the XML format, which is more favorable for the conversion and analysis of the data.
Step S16, receiving the geometric topology information of the mark of the three-dimensional product object in the CAD software, and sending the received geometric topology information of the mark to target CAM software, so that the target CAM software automatically reconstructs according to the received geometric topology information of the mark to obtain a three-dimensional geometric model;
specifically, the geometric topology information is transferred to a neutral geometric format, a universal standard API Interface (Application Programming Interface) is called to identify the neutral geometric format information, and the neutral geometric format information is reconstructed in the target CAM software to obtain the three-dimensional geometric model.
Step S17, receiving the data set and sending the received data set to the target CAM software;
and establishing a data receiving port and a data sending port, wherein the data receiving port is used for receiving the data set and sending the data set to the target CAM software through the data sending port.
Step S18, analyzing the data set in the target CAM software to obtain the labeled non-geometric information;
and the preset data analysis unit is used for analyzing the data set received in the target CAM software.
Step S19, retrieving the correspondence table, and matching the analyzed labeled non-geometric information with the three-dimensional geometric model reconstructed in the target CAM software based on the correspondence table, so as to create the non-geometric information on the three-dimensional geometric model in the target CAM software.
Specifically, the non-geometric information is matched with a three-dimensional geometric model reconstructed in the target CAM software, the non-geometric information is matched with the geometric topology information on the three-dimensional geometric model reconstructed in the target CAM software, and the non-geometric information is matched with the geometric topology information on the three-dimensional geometric model reconstructed in the target CAM software according to the correspondence table, so as to create the non-geometric information on the three-dimensional geometric model in the target CAM software.
The method comprises the steps of reading geometric topological information and non-geometric information of a three-dimensional product object in CAD software, defining and marking the geometric topological information and the non-geometric information, wherein the marking can be carried out in a coding, color or topological attribute mode, establishing a corresponding relation between the marked geometric topological information and the non-geometric information to form a corresponding table, converting the non-geometric information into a data set in an XML format, importing the marked geometric topological information and the data set into target CAM software, reconstructing the geometric topological information by the target CAM software, analyzing the imported data set, obtaining the marked non-geometric information in the target CAM software, calling the corresponding table, matching the non-geometric information in the target CAM software with the geometric topological information of a reconstructed three-dimensional CAM geometric model, and realizing the creation of the non-geometric information on the three-dimensional geometric model in the target CAM software, and the sharing of non-geometric information between the CAD software and the CAM software is realized.
