Major manufacturers have adopted various CAD tools based on different needs and preferences. Even the same manufacturer may change CAD software in response to technological innovation or project needs at different stages of its growth. However, the basic models created by these CAD software are often in proprietary formats and cannot be applied to other CAD software. If you try to open them with non-native CAD software, key parameter information in the model may be lost. This requires designers to use CAD software that matches the model to access and edit it to ensure that the model meets the required specifications.

[0003] At present, in the process of parts selection, in order to improve efficiency, reduce costs and promote resource recycling, manufacturers tend to reuse old parts already in the company, or directly adopt standardized parts provided by parts suppliers.

Therefore, how to convert and share model data between different CAD software, improve the accuracy and efficiency of model file conversion, and then improve the efficiency of parts selection and reuse has become an important issue that needs to be solved in the current industrial manufacturing design field.

[0050] Figure 1 is an optional flow chart of the CAD-based model file conversion method provided in an embodiment of the present application, Figure 1 The method may include but is not limited to steps S101 to S103.

[0051] Step S101, receiving a first model file input by a user, and determining a first CAD software corresponding to the first model file;

[0052] Step S102, determining deformation parameters corresponding to the first model file, and generating a corresponding parameter mapping table based on the deformation parameters;

[0053] Step S103: generating a deformation request based on the first model file, the first CAD software and the parameter mapping table, and outputting a second model file corresponding to the second CAD software based on the deformation request.

[0054] Steps S101 to S103 shown in the embodiment of the present application, by receiving a first model file input by a user and determining the first CAD software corresponding to the first model file, can accurately determine the created first CAD software based on the model file format, so as to facilitate the subsequent judgment whether the model file corresponding to the CAD software can be converted; by determining the deformation parameters corresponding to the first model file, the deformation parameters corresponding to the first model file can be accurately determined, so as to facilitate the generation of a corresponding parameter mapping table based on the deformation parameters, and further facilitate the subsequent conversion of the model file corresponding to the CAD software; by judging whether the model file corresponding to the CAD software can be converted, a deformation request is generated, and based on the deformation request, a second model file corresponding to the second CAD software is output, model data can be converted and shared between different CAD software, thereby improving the accuracy and efficiency of model file conversion, and further improving the efficiency of component selection and reuse.

[0055] See also Figure 2In some embodiments, step S101 may include but is not limited to steps S201 to S202:

[0056] Step S201, performing feature extraction on the file format corresponding to the first model file to obtain a feature extraction result;

[0057] Step S202: determining the first CAD software corresponding to the first model file based on a preset CAD software format list and the feature extraction result.

[0058] In step S201 of some embodiments, after receiving the first model file input by the user, feature extraction can be performed on the file format corresponding to the first model file. Specifically, by using the "." in the file name as a separator, the suffix (also called the file extension) of the first model file is extracted to obtain the feature extraction result. Of course, this step can be implemented by but is not limited to writing a programming language.

[0059] It should be noted that each model file has its own special file suffix, which is the part of the file name after the last dot (.). It is usually used to indicate the type or format of the file. For example, in the file name example.dwg, the file suffix is ​​.dwg.

[0060] In step S202 of some embodiments, it is necessary to first create a CAD software format list including CAD software and its corresponding file extension (i.e., feature extraction results), and this CAD software format list can be hard-coded in the program or read from an external configuration file or database; after the CAD software format list is created, the feature extraction result can be compared with the content in the CAD software format list, that is, it is possible but not limited to traversing the list by writing a programming language to check whether the file extension (i.e., feature extraction result) exists in the file extension list of a certain CAD software. If so, the first CAD software corresponding to the first model file can be directly determined.

[0061] Step S101 shown in the embodiment of the present application can automatically, quickly and accurately identify which CAD software created the model file or which CAD software should open it by, by extracting the file format features corresponding to the first model file and comparing it with the preset CAD software format list, so as to facilitate the subsequent judgment of whether the model file corresponding to the CAD software can be converted.

[0062] See also Figure 3 In some embodiments, step S102 may include but is not limited to steps S301 to S302:

[0063] Step S301, determining deformation parameters corresponding to the first model file;

[0064] Step S302: Generate a corresponding parameter mapping table based on the deformation parameters.

[0065] In step S301 of some embodiments, it is necessary to collect several third model files corresponding to CAD software in advance, confirm the model attributes, and determine the type, requirements and goals of deformation, and train the corresponding analysis model based on the model attributes, type, requirements and goals of deformation to analyze the deformation parameters corresponding to the first model file. After the analysis model is trained, the deformation parameters corresponding to the first model file can be directly obtained by inputting the first model file into the analysis model.

[0066] In step S302 of some embodiments, after the deformation parameters are determined, the deformation parameters need to be used as query conditions, and the corresponding 3D model variables can be searched in the data structure table containing the deformation parameters and the 3D model variables by, but not limited to, writing query statements, etc. If a match is found, the identifier corresponding to the 3D model variable is obtained to obtain a number of query results, wherein the query result reflects the mapping relationship between the deformation parameters and the 3D model variables, and the several query results are converted into a table form to obtain a number of parameter mapping tables corresponding to the deformation parameters. If no match is found in the data structure table containing the deformation parameters and the 3D model variables, it may be necessary to report an error or take other recovery measures.

[0067] It should be noted that the data structure table is a set of key-value pairs defined based on the pre-organized official documents, tutorials, professional books or online resources, where the key is the name of the deformation parameter and the value is the identifier of the 3D model variable associated with the parameter (such as a variable name, path or index).

[0068] Step S102 shown in the embodiment of the present application can accurately determine the deformation parameters corresponding to the first model file by determining the deformation parameters corresponding to the first model file, thereby facilitating the generation of a corresponding parameter mapping table based on the deformation parameters, and further facilitating the subsequent conversion of the model file corresponding to the CAD software.

[0069] See also Figure 4 In some embodiments, step S103 may include but is not limited to steps S401 to S402:

[0070] Step S401, generating a deformation request based on the first model file, the first CAD software and the parameter mapping table;

[0071] Step S402: outputting a second model file corresponding to the second CAD software based on the deformation request.

[0072] In step S401 of some embodiments, step S401 may include but is not limited to determining whether the first model file can be deformed based on the first model file, the first CAD software and the parameter mapping table; if the first model file can be deformed, generating a deformation request based on a CAD interface corresponding to the second CAD software. The specific content is as follows.

[0073] In step S402 of some embodiments, after obtaining the deformation request, it is necessary to first determine the specific content of the deformation request, including the type of deformation, the degree of deformation, and the specific parameters that may be involved, start the second CAD software for generating the second model file, and import the first model file; then, find the deformation-related tools or commands in the toolbar or menu of the second CAD software, and select the appropriate deformation tool and set the deformation parameters according to the specific requirements of the deformation request: finally, according to the deformation request, set the parameters required for the deformation, such as the deformation direction, distance, angle, etc., and apply the set deformation parameters to perform the deformation operation. After the deformation operation is completed, output the second model file corresponding to the second CAD software.

[0074] Step S103 shown in the embodiment of the present application generates a deformation request by determining whether the model file corresponding to the CAD software can be converted, and outputs a second model file corresponding to the second CAD software based on the deformation request. This enables model data conversion and sharing between different CAD software, thereby improving the accuracy and efficiency of model file conversion, and further improving the efficiency of component selection and reuse.

[0075] See also Figure 5 In some embodiments, step S401 may include but is not limited to steps S501 to S502:

[0076] Step S501, judging whether the first model file can be deformed based on the first model file, the first CAD software and the parameter mapping table;

[0077] Step S502: If the deformation is possible, a deformation request is generated based on the CAD interface corresponding to the second CAD software.

[0078] In step S501 of some embodiments, after obtaining the first model file, the first CAD software and the parameter mapping table, it is necessary to first confirm whether the first model file is compatible with the second CAD software, which usually involves a compatibility check of the file format. If the file format is incompatible, it may be necessary to convert the format first. If the file format is compatible, it is necessary to further analyze the parameter mapping table to confirm whether the parameters contained therein are sufficient to support the required deformation operation on the first model file, and then determine whether the first model file can be deformed. If the model files are compatible and the parameter mapping table is complete, it is determined that the first model file can be deformed. If the first model file cannot be deformed, an error is reported and the user is reminded.

[0079] In step S502 of some embodiments, after determining that the first model file can be deformed, it is necessary to determine the required deformation parameters and their target values ​​based on the parameter mapping table, and then generate a deformation request through the CAD interface corresponding to the second CAD software, that is, the programming interface (such as API) by writing a deformation script or command, wherein the script or command should include a reference to the model file, the specification of the deformation parameters, and instructions for performing the deformation operation.

[0080] Step S401 shown in the embodiment of the present application determines whether the second CAD software can deform the first model file, and generates a deformation request based on the CAD interface corresponding to the second CAD software, so as to facilitate subsequent model data conversion and sharing between different CAD software, improve the accuracy and efficiency of model file conversion, and further improve the efficiency of component selection and reuse.
