DETAILED DESCRIPTION

[0021] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of this specification, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0022] The embodiment of the present invention provides a multi-level and multi-professional CAD model library management method, such as Figure 1 As shown, the multi-level and multi-professional CAD model library management method specifically includes steps S101-S104: S101. Define the standard data architecture for various professional models in various professional fields.

[0023] Specifically, firstly, various professional element models in various professional fields are obtained, and various professional models in each professional field are abstracted into a document set; a document in each set represents a professional element model.

[0024] Furthermore, the expression methods of various professional element models are analyzed in the document collection to extract common data expression fields. Then, based on the common data expression fields, the corresponding standard data structure is constructed and the corresponding standard data storage format is specified. The standard data structure and the standard data storage format constitute the standard data architecture.

[0025] As a feasible implementation method, since the professional element model data in multiple professional fields is relatively complex and changeable, MongoDB document database is selected to store professional element models. Different professional CAD models in different professional fields (such as general machinery, chemical industry, petrochemical industry, energy, aviation, etc.) are abstracted into different document collections. The documents in each collection represent a professional element model. These documents uniformly use JSON format to store data to ensure the interoperability of data between different systems and modules.

[0026] As a feasible implementation method, after analyzing different professional element models, the extracted standard data structure mainly includes the following fields: id: unique index of professional element model, primary key; name: name of the professional element model; knowledgeType: the type to which the professional element model belongs, including folder, general machinery, petrochemical, etc. folderCode: the folder id where the professional element model is stored; thumbnail: thumbnail of the professional element model; createUserId: the id of the user who created the professional element model; createUserName: the name of the user who created the professional feature model; createTime: creation time of the professional feature model; repositoryId: the unique id of the corresponding repository where the professional element model is stored; status: the status of the professional element model, including under review, rejected, stored, etc. param: other attribute information of the professional feature model, stored in the form of key-value pairs, where key is the attribute name and value is the attribute value; including description, code, associated model id, file corresponding to the model, etc.

[0027] When CAD models are put into the database, they are all put into the database in accordance with the above-mentioned standard data structure, thus forming a unified model storage standard.

[0028] S102: Obtain model information of the professional element model drawn by the current user, and parse the model information to obtain model parsing information.

[0029] Specifically, first, the user manually draws the professional element model in the client interface based on the basic modeling tools and various parametric modeling tools provided by CrownCAD to complete the creation of the professional element model.

[0030] As a feasible implementation method, Figure 2 An example diagram of a professional element model drawing provided by an embodiment of the present invention is shown in FIG. Figure 2 As shown, the model creation process is as follows: 1. Create a document: Create a component document from CrownCAD; 2. Draw a 2D sketch: open the document, enter the sketch drawing, and use the rectangle tool, straight line tool, ellipse tool, line tool, etc. to draw the 2D outline of the professional element model; 3. Define variable expressions and use variable tools to define variable data required by professional element models; 4. Apply design constraints: Apply design constraints in 2D sketches, such as dimensional constraints, geometric constraints, etc. 5. Generate professional element models: Use operations such as stretching, rotating, and scanning to convert the two-dimensional contours into corresponding three-dimensional professional element models; 6. Add parametric features: Add other parametric features to the professional element model, such as chamfers, fillets, etc.

[0031] Figure 3 A schematic diagram of a professional factor model storage execution process provided by an embodiment of the present invention, such as Figure 3 As shown, after the current user draws the professional element model in the client, the client collects the model information of the professional element model and generates an EXCEL spreadsheet file; wherein the model information at least includes model specification information, model size information and model attribute information.

[0032] Furthermore, the EXCEL table is uploaded to the server, and the data in the EXCEL file is parsed to obtain model parsing information; wherein the model parsing information at least includes: model creation user information, model name, model specification information, model size information and model attribute information.

[0033] S103. Based on the standard data architecture, encapsulate the professional element model and model analysis information into a data structure to obtain a data structure corresponding to the professional element model.

[0034] Specifically, Figure 3 As shown in the figure, after parsing the data in the EXCEL file, the server converts the professional element model into a JSON format document, and performs format conversion and field value extraction together with the model parsing information according to the standard data architecture. The extracted field values ​​are filled into the fields defined in the standard data architecture to assemble a unified standard model data structure.

[0035] S104, verifying the identity authority of the current user. If the verification is successful, the data structure corresponding to the professional element model is stored in the CAD model library.

[0036] Specifically, Figure 3 As shown in the figure, after assembling the unified standard model data structure, the server obtains the user information of the current user based on the model parsing information of the professional element model. Then, based on the user information, it verifies whether the current user has the storage permission. If the user has the storage permission, the data structure corresponding to the professional element model is stored in the CAD model library. If the user does not have the storage permission, an error message is returned.

[0037] As a feasible implementation method, the CAD model library is a multi-level model library; the multi-level model library includes at least a personal library, a project library, an enterprise library, an industry library and a public model library. In the multi-level model library, each model library contains different user roles and corresponding user management permissions.

[0038] Among them, the personal library is a user's private library. The user who owns the personal library has all the permissions of the model library; The roles in the project library include project administrators, project accumulators, and project members. Project members and project accumulators are designated by project administrators. Project accumulators have the authority to enter models into the library, while project administrators have the authority to review, enter, and manage models. Project members only have the authority to use models. The roles in the enterprise library include enterprise administrator, enterprise library manager, enterprise library entrant and enterprise library member; the enterprise administrator has the authority to create an enterprise library, and the authority to designate enterprise library administrators, enterprise library entrants and enterprise library members. The enterprise administrator and enterprise library manager have the authority to manage enterprise library personnel and the authority to review and manage the enterprise library; enterprise entrants only have the authority to enter enterprise models; enterprise library members only have the authority to use the enterprise model library; The roles in the industry library include platform administrators, warehousing personnel, and users. Platform administrators have the authority to designate warehousing personnel and users, as well as the authority to manage industry library models. warehousing personnel only have the authority to warehousing industry library models, and users only have the authority to use industry library models. The public model library is a model library that can be used by all users, but each user can only manage and use the model data that he or she has stored in the library.

[0039] The multi-level and multi-professional model library mechanism technology is based on the basic modeling function of the online 3D design platform and professional parametric modeling tools, enabling designers to quickly design industry element models and quickly create fully parameter-driven element models based on the relationships between all elements in the model. In the process of model storage, all specifications, dimensions, attributes and other data of professional element models in the field are collected, and the model is imported into the library through the library building tool function. The model specifications, dimensions, attributes and other data of the model are imported in batches by using the powerful table capabilities of EXCEL and other powerful tables. With the help of the library building tool capabilities, the model and data (specifications, dimensions, attributes) are stored in the database, and storage management is performed through object storage and text data storage, which facilitates users to access and manage their own data anytime and anywhere. It supports model libraries at different levels, including personal libraries, project libraries, enterprise libraries, industry libraries and public model libraries. Through different levels of permission control and data management, data sharing and resource management in different application scenarios can be achieved.

[0040] In addition, the embodiment of the present invention also provides a multi-level and multi-professional CAD model library management system, such as Figure 4 As shown, the multi-level and multi-professional CAD model library management system 400 includes: A standard setting module 410 is used to define the standard data architecture of various professional models in various professional fields; The model data structure extraction module 420 is used to obtain the model information of the professional element model drawn by the current user, and parse the model information to obtain the model parsing information; based on the standard data architecture, the professional element model and the model parsing information are encapsulated into a data structure to obtain the data structure corresponding to the professional element model; The identity verification and storage module 430 is used to verify the identity authority of the current user. If the verification is successful, the data structure corresponding to the professional element model is stored in the CAD model library.

[0041] Finally, an embodiment of the present invention further provides a storage medium, which is a non-volatile computer-readable storage medium, and the non-volatile computer-readable storage medium stores at least one program, each of which includes instructions, and when the instructions are executed by a terminal, the terminal executes: Define standard data architectures for various professional models in various professional fields; Acquire model information of the professional element model drawn by the current user, and parse the model information to obtain model parsing information; Based on the standard data architecture, encapsulate the professional element model and the model parsing information into a data structure to obtain a data structure corresponding to the professional element model; Verify the identity authority of the current user, and if the verification is successful, store the data structure corresponding to the professional element model into the CAD model library.

[0042] Compared with the traditional model library mechanism, the technical solution of the present invention defines and manages models in different professional fields in a unified manner by defining a unified data structure and standard, which breaks down traditional barriers, promotes the integration of knowledge and technology in different professional fields, and helps enterprises reduce repetitive work and improves product R&D efficiency. By defining a unified management mechanism and multi-level model library classification, the centralized management of models in multiple professional fields by the enterprise and the sharing and collaborative management of model resources by designers within the enterprise are realized. By using technical means such as more detailed access control and authority management according to the level, the security and privacy of model data within the enterprise are further ensured.
