Description

Technical Field

[0001] The present invention relates to the field of design and manufacturing of large equipment, and specifically to a method, system, device and medium for interaction between dimensions and graphics. Background Art

[0002] The statements in this section only provide background information related to the present disclosure and may not constitute prior art.

[0003] With the deepening application of three-dimensional digital technology, digital design and manufacturing technology based on Model Based Definition (MBD) has become the development trend of informatization in the manufacturing industry. MBD is the digital definition based on a model. Its core idea is a method of using an integrated three-dimensional solid model to completely express product definition information, which details non-geometric information such as dimensions, roughness, tolerance markings, references, technical requirements, etc. of the product in the three-dimensional solid model, and fully integrates the three-dimensional product design geometric information and non-geometric information into the three-dimensional model, forming a complete set of three-dimensional engineering drawings. It takes the three-dimensional model as the sole basis in the production and manufacturing process, changing the traditional research and development mode that mainly relies on engineering drawings and supplemented by three-dimensional solid models. Compared with the traditional mode, the manufacturing technology based on the MBD data set as the sole basis has brought about a transformation in the production mode and more effectively improved the convenience brought by digital technology. The model structure of MBD is as Figure 2 shown, and the MBD data set structure is as Figure 3 shown.

[0004] The amount of information contained in the three-dimensional model is much larger than that of traditional two-dimensional drawings. Some of these annotation information can be directly obtained from the design model, such as geometric dimensions; some are manually generated during annotation, such as references, tolerances, surface roughness, etc.; and some can be read from the enterprise database, such as information on equipment, tools, etc. involved in the processing method. Such a large amount of information poses high requirements for storage technology and transmission technology. In order to achieve rapid retrieval, query and editing of information, it is necessary to study how to structurally manage this information. Summary of the Invention

[0005] The purpose of the present invention is to provide a method, system, device and medium for interaction between dimensions and graphics, which, based on the structuring of MBD dimension annotations, converts the dimension annotation information represented by the graphics and unrecognizable by the computer into an ordered record recognizable by the computer, and realizes the application of dimension-graphics interaction in the field of production quality inspection for the problems existing in the prior art.

[0037] It should be noted that relational terms such as "first" and "second" are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprise", "include" or any other variant thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article or device. Without further limitation, an element defined by the phrase "comprising an..." does not exclude the presence of additional identical elements in the process, method, article or device comprising the element.

[0038] The features and performance of the present invention will be further described in detail below in conjunction with the embodiments.

[0039] Embodiment 1

[0040] First of all, it should be noted that the structuring of annotation information is to associate three-dimensional annotation information with the three-dimensional model of the product according to a certain hierarchical structure and store it, so that this information can be retrieved and managed by a computer. In the past, the annotation information on engineering drawings was scattered, and retrieval and management relied on manual operations and could not be automatically recognized by a computer. In this embodiment, views are used to quickly and clearly manage the information related to design processes. That is, in a three-dimensional environment, various views similar to two-dimensional drawings are constructed, and different types of annotation information are classified and organized for management under different views.

[0041] Please refer to Figures 1-5 , a method for the interaction between dimensions and graphics based on the structuring of MBD dimension annotations, specifically including:

[0042] Generate a three-dimensional MBD model containing geometric information and non-geometric information;

[0043] Construct a view classification system in a three-dimensional environment, and the view classification system is used to classify and organize different types of annotation information;

[0044] Extract the annotation information of the three-dimensional model and store it as a structured two-dimensional table;

[0045] Establish an association mapping relationship between the two-dimensional table records and the three-dimensional annotations;

[0046] In response to the user's selection operation on the two-dimensional table records, automatically switch the three-dimensional model to the corresponding view and highlight the target annotation;

[0047] That is, during the design stage, designers express the main information in the two-dimensional drawing more completely on the three-dimensional model, express the component information completely at the design source, and at the same time can meet the utilization in various links of the product life cycle such as subsequent processes, manufacturing, production, inspection, and maintenance. The content of the three-dimensional annotation should mainly include views, dimensions and dimensional tolerances, and technical requirements. As Figure 1 shown;

[0048] In this embodiment, specifically, the two-dimensional table contains fields such as annotation number, view name, dimension type, dimension value, upper tolerance, and lower tolerance. The annotation number is used as the unique identifier.

[0049] In this embodiment, specifically, the structured two-dimensional table further contains a grid information field for recording the positioning information of the annotation in the three-dimensional model.

[0050] In this embodiment, specifically, the extracted 3D model annotation information includes dimensional tolerances, geometric tolerances, and datum information; that is, dimensions and dimensional tolerances, datums and geometric tolerances, etc., which can be directly annotated on the 3D model.

[0051] In this embodiment, specifically, the view switching operation is performed based on the view name field recorded in the two-dimensional table.

[0052] In this embodiment, specifically, the highlighting operation is achieved by changing the rendering attributes of the annotated entities.

[0053] In the actual use process, according to design requirements, process requirements, manufacturing requirements, quality inspection requirements, etc., technicians extract target dimensions from the annotation set of the 3D model, and the extracted dimensions will be stored in a two-dimensional table as shown in Figure 4 The columns of the two-dimensional table include annotation number, grid information, view name, dimension type, dimension value, upper tolerance, lower tolerance, suffix, prefix, description, etc. It is uniquely identified by the annotation number. Thus, the transformation from image expression to structured expression is realized, as shown in Figure 4 shown.

[0054] After realizing the structuring of MBD dimension annotation, when a technician randomly clicks on a row of dimension records in the two-dimensional table storing dimension annotations, the 3D model will switch to the corresponding view, and the corresponding annotation will be highlighted. This is the interaction between dimensions and graphics. As shown in Figure 5 shown. In the production process, most traditional quality inspection activities are carried out in the form of a quality inspection item list accompanied by two-dimensional drawings. Technicians need to spend a lot of time looking for the dimensions to be measured on the two-dimensional drawings, and there is a certain error rate. The dimension and graphics interaction function introduced in this article can automatically help technicians locate the dimension positions, with faster and more accurate positioning, improving the detection efficiency and accuracy rate, and having higher economic benefits.

[0055] This method introduces the concept of views similar to those in two-dimensional drawings in 3D annotation to facilitate the positioning and orientation of parts when performing dimension, tolerance, etc. annotation, helping relevant personnel such as those involved in the process, manufacturing, and quality inspection of the 3D model to quickly orient, and improving the reading efficiency of the 3D model.

[0056] Embodiment 2

[0062] An interactive response module for implementing a linkage response between two-dimensional table record selection and three-dimensional annotation positioning.

[0063] Through the above system, it is possible to implement a dimension and graphics interaction method based on MBD dimension annotation structuring proposed in Embodiment 1.

Alternatively, the processor can also be called a controller, and the name is not limited.

[0070] In the embodiments of the present invention, the memory stores instructions executable by at least one processor, and at least one processor, by executing the instructions stored in the memory, can execute a collaborative resource configuration optimization method based on network nodes and software described above.
