Description

Technical Field

[0001] The present invention relates to the field of digital design, and in particular to a digital method based on two-way interaction between models and documents. Background Art

[0002] With the development of digital technology, the MBD (Model Based Difinition) design method is becoming more and more common. Its core idea is to integrate traditional mechanical design information such as product-related geometry, dimensions, tolerances, surface roughness, and technical requirements related to product design and manufacturing process status into the product 3D model based on a 3D solid model, and use the model as the basis for design and manufacturing. However, in actual design and manufacturing applications, this method also has some shortcomings: (1) The model naturally carries geometric design information, and non-geometric design information can also be integrated into the model in the form of background parameters. However, it is inevitable that some design information still needs to be described in text, tables, and diagrams; (2) In various industries or enterprises, there are links such as technical exchanges, quality review, and meeting reviews related to research and development work. When communicating with humans, documents are still needed as a carrier. Compared with models, documents are more complete and unified; (3) In actual manufacturing, production, and operation, it is difficult to have computers with 3D software installed in all scenarios. Therefore, model-based design information cannot be presented around the clock and in all time domains. In this case, the document still needs to be printed out for use.

[0003] In summary, the MBD design method cannot completely replace documents. The existence of documents is reasonable and necessary, but the advantages of models are also unquestionable. How to combine the advantages of both and solve the above-mentioned shortcomings at the same time. The present invention proposes a digital method based on two-way interaction between models and documents, which can efficiently integrate the relationship between models and documents and solve related problems. Summary of the invention

[0004] In order to overcome the deficiencies in the prior art, the present invention provides a digitization method based on two-way interaction between models and documents, which can unify the design information of three-dimensional models and document files, avoid the problem of inconsistent information from multiple data sources, and greatly improve the efficiency of writing design documents.

[0005] In order to achieve the above-mentioned invention object, the technical solution adopted to solve the technical problem is as follows: A digitalization method based on bidirectional interaction between models and documents, the method involves three types of file objects: a three-dimensional model, an interface interaction file and a word document. The three-dimensional model and the word document are design files, which contain design information in a structured form and are legal documents for design constraints of related parties. The interface interaction file is a bridge for information interaction between the three-dimensional model and the word document. The bidirectional interaction between the three-dimensional model and the word document is realized through four information interaction paths, including: Path 1: Export information of the 3D model to the interface interaction file; Path 2: Copy information from the interface interaction file to the word document; Path 3: Information mapping from word document to interface interaction file; Path 4: The interface interaction file is read by the 3D model information.

[0006] Furthermore, an XML format file is used as an interface interaction file for bidirectional interactive design information between the three-dimensional model and the word document.

[0007] Furthermore, various geometric features and non-geometric parameter information of the three-dimensional model are stored in the three-dimensional model file, structured according to a unified data interface format, and exported in a tabular form to an XML format interface interaction file, thereby realizing information interaction path 1.

[0008] Furthermore, the tabular information in the XML format interface interaction file output by the three-dimensional model is copied into a word document to form a standard formatted document file. The relevant design information can be modified in the word document as needed, thereby realizing information interaction path 2.

[0009] Furthermore, through the structured mapping relationship, the relevant design information is modified in the word document to update the corresponding XML format interface interaction file, thereby realizing information interaction path 3.

[0010] Furthermore, the design information of the interface interaction file in XML format can be modified through a word document, or the design information of the interface interaction file in XML format output by the three-dimensional model can be directly modified. The modified and updated interface interaction file in XML format can be read by the three-dimensional model, and the three-dimensional model can be driven by the updated design information in the interface interaction file in XML format to modify and update the three-dimensional model, thereby realizing information interaction path 4.

[0011] Furthermore, after the modification and update, the three-dimensional model can be exported again as an XML format interface interaction file, which is used to update the design information in the word document so that the design information is consistent with the three-dimensional model, thereby realizing the digital twin of the model and document.

[0012] Furthermore, the two-way interactive process can be completed with one click through software tools, and both geometric information and non-geometric information in the three-dimensional model can be displayed in a cruise and browsing manner through the software.

[0013] Due to the adoption of the above technical solution, the present invention has the following advantages and positive effects compared with the prior art: After the design information in the three-dimensional model of the present invention is structured, a form can be generated on demand for design document writing, which greatly improves efficiency. At the same time, the design information of the three-dimensional model and the document file can be unified to avoid the problem of inconsistent information from multiple data sources.

As shown in the figure, this embodiment discloses a digitization method based on two-way interaction between models and documents. The method involves three types of file objects: a three-dimensional model, an interface interaction file, and a word document. The three-dimensional model and the word document are design files, which contain design information that structures data and are legal documents for design constraints of related parties; the interface interaction file is a bridge for information interaction between the three-dimensional model and the word document. The two-way interaction between the three-dimensional model and the word document is realized through four information interaction paths, including: Path 1: Export information of the 3D model to the interface interaction file; Path 2: Copy information from the interface interaction file to the word document; Path 3: Information mapping from word document to interface interaction file; Path 4: The interface interaction file is read by the 3D model information.

[0017] See also Figure 2 The present invention adopts a digital design method based on MBD. Based on the three-dimensional model, the traditional mechanical design information related to the product, such as geometric shape, size, tolerance, surface roughness, and the technical requirements related to the product design and manufacturing process status, are integrated into the product three-dimensional model; for some descriptive technical requirements that are inconvenient or cannot be given based on the model, they are still given through word documents as the carrier. Both the three-dimensional model and the word document serve as the basis for design and manufacturing. On this basis, a unified and data-structured design information interface is designed for the three-dimensional model and the word document, and an xml format interface interaction file is used as the interface interaction file of the three-dimensional model and the word document, so that the same design information can be transmitted bidirectionally between the three-dimensional model and the word document.

[0018] Furthermore, various geometric features, non-geometric parameters and other information of the 3D model are stored in the 3D model file. Figure 3 , according to the unified data interface format structure, it can be exported in a tabular form to an XML format interface interaction file, thereby realizing information interaction path 1.

[0019] The tabular information in the XML format interface interaction file output by the 3D model is copied into a Word document to form a standard formatted document file. The relevant design information can be modified in the Word document as needed, thereby realizing information interaction path 2.

[0020] Through the structured mapping relationship, the relevant design information can be modified in the word document to update the corresponding XML format interface interaction file, thereby realizing information interaction path 3.

[0021] Furthermore, the design information of the interface interaction file in XML format can be modified through a word document, or the design information of the interface interaction file in XML format output by the three-dimensional model can be directly modified. The modified and updated interface interaction file in XML format can be read by the three-dimensional model, and the three-dimensional model can be driven by the updated design information in the interface interaction file in XML format to modify and update the three-dimensional model, thereby realizing information interaction path 4.

[0022] After the modification and update, the 3D model can be exported again as an XML format interface interaction file, which is used to update the design information in the Word document so that the design information is consistent with the 3D model, thereby realizing the digital twin of the model and document.

[0023] In this embodiment, the two-way interactive process can be completed with one click through a software tool, and both geometric information and non-geometric information in the three-dimensional model can be displayed through the software in the form of cruising, browsing, etc.

Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the present invention should be included in the protection scope of the present invention.
