Description

Technical Field

[0001] The present invention relates to the technical field of detail list generation, and in particular to a method, system, device and storage medium for generating a three-dimensional drawing detail list. Background Art

[0002] A 3D drawing schedule is a detailed list created in 3D CAD and other software to record and display detailed information on each component, part or material in a design. This information usually includes the name, quantity, material, size, etc. of the part, helping designers, engineers and manufacturers to manage and track the production process. The functions of a 3D drawing schedule include information management, production preparation, cost control and quality control. By establishing a 3D drawing schedule, users and designers can be provided with clear and accurate detailed information in the 3D model.

[0003] The existing method for generating a 3D drawing list is usually to obtain the information data of the parts within the list generation range based on the 3D modeling corresponding to the 3D drawing, and generate the 3D drawing list based on the information data of the parts. Although this generation method can ensure that the data in the 3D drawing list is consistent with the actual 3D modeling, thereby improving the accuracy of the data, this generation method is relatively conventional and only transfers the existing data. There is a lack of clear marking for the location data of each part in the 3D drawing and the association data of each part with other parts. This will result in the inability of users or designers to effectively judge the parts in the 3D drawing when performing data analysis based on the 3D drawing list. The position in the three-dimensional modeling and the relationship between the parts lead to problems that affect the data analysis efficiency of users and designers. For example, in the patent application with publication number CN119203951A, a method, device, equipment, storage medium and program product for generating a drawing list are disclosed. The solution is to dynamically generate a two-dimensional drawing list of the parts within the generation range of the target three-dimensional model, thereby improving the generation efficiency and accuracy of the drawing list. Other improvements for three-dimensional drawing lists, usually improvements in the annotation of parent-child relationships of parts, still cannot solve the above technical problems. In view of this, it is necessary to improve the existing method for generating three-dimensional drawing lists. Summary of the invention

[0041] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions 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 the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] Example 1, please refer to Figure 1 As shown, the present application provides a three-dimensional drawing detail list generation system, including a plane layered analysis module, a multi-component association module, and a detail list nesting generation module;

[0043] The plane layered analysis module is used to record the 3D model corresponding to the 3D drawing as the 3D original model; record the closed figures in the 3D drawing as the component section, and obtain the parts corresponding to each component section based on the 3D original model, and record them as component parts; obtain the layered detailed list of the 3D drawing using the component layering method based on all component sections and component parts;

[0044] See also Figure 3 As shown, the component layering method includes: numbering all component sections from small to large based on the area of ​​each component section; for any component section, obtaining the component section corresponding to the component section in the three-dimensional original model based on the three-dimensional original model, and recording it as the component part; obtaining the surface area of ​​the component part, and recording the value of the area of ​​the component section divided by the surface area of ​​the component part as the part ratio of the component section;

[0045] In the specific implementation process, for example, in a data processing, the surface area of ​​the component part is 5cm², the surface area of ​​the component part is 20cm², and the area of ​​the three-dimensional drawing is 50cm². Then, by calculation, the part ratio is 0.25 and the drawing ratio is 0.1; by obtaining the part ratio and the drawing ratio, the proportion of the component section in the three-dimensional drawing in the component part and the three-dimensional drawing can be obtained; the larger the part ratio and the drawing ratio, the larger the exposed part of the component part, that is, the more the component part is on the outside in the direction corresponding to the three-dimensional drawing in the three-dimensional original model; the smaller the part ratio and the drawing ratio, the smaller the exposed part of the component part, that is, the more the component part is on the inside in the direction corresponding to the three-dimensional drawing in the three-dimensional original model;

[0046] The value of the component section area divided by the area of ​​the three-dimensional drawing is recorded as the drawing scale of the component section; the part scale and drawing scale of all component sections are obtained; the maximum, minimum and average values ​​of all part scales are recorded as L max , L min and L sq , the maximum, minimum and average values ​​of all drawing scales are recorded as T max , T min and T sq ;

[0047] All parts whose proportions are in the interval [L min , L sq ] is recorded as A1, and all parts whose proportions are in the interval [L sq , L max] is recorded as A2; all the drawings with a scale in the interval [T min , T sq ] is recorded as B1, and all the drawings with the scale in the interval [T sq , T max ] is recorded as B2; the double proportion algorithm is used to obtain the component classification quantity, and the double proportion algorithm is , where h is the number of component levels;

[0048] In the specific implementation process, for example, in a data analysis, the proportion of all parts obtained is in the interval [L min , L sq ] is 5, and the proportion of all parts is in the interval [L sq , L max ] is recorded as 5, and all drawing scales are in the interval [T min , T sq ] is recorded as 3, and all drawing scales are in the interval [T sq , T max ] is 7, then by calculation, the number of component classifications is 3; by obtaining the number of component classifications based on the above data, it can be ensured that the obtained number of component classifications conforms to the distribution of the part ratio and the drawing ratio. When the number of part ratios or drawing ratios in a certain interval is large, the number of component analyses obtained will increase. When the distribution of part ratios or drawing ratios is more uniform, the number of component analyses obtained will decrease, so that the number of part sub-intervals LZ obtained is more in line with the actual situation;

[0049] The interval [L min , L max ] is evenly divided into the number of component classifications, and based on the maximum value in each portion, the obtained intervals are recorded as part sub-intervals LZ in descending order. 1 To part sub-interval LZ h ; The interval [T min , T max ] is evenly divided into the number of component classifications, and based on the maximum value in each portion, the obtained intervals are recorded as drawing sub-intervals TZ in descending order. 1 To the drawing sub-interval TZ h ;

[0050] For any component section, the component section part ratio and the drawing ratio of the component section part sub-interval LZ and the drawing sub-interval TZ are respectively recorded as part sub-interval LZ α And the drawing sub-interval TZ β; When α and β are equal, the number of layers of the component section is recorded as α, and the component section is marked as the αth layer section; when α and β are not equal, the number of layers of the component section is recorded as γ, and the component section is marked as the γth layer section, where γ is the maximum value between α and β;

[0051] A table of h+1 rows×F columns is established and recorded as a hierarchical detail table, wherein the leftmost column of the hierarchical detail table is filled with the 1st to the hth layer of sections from top to bottom except the first cell, and the top row of the hierarchical detail table is filled with the numbers of all component sections from left to right except the leftmost cell; based on the numbers of all component sections and the number of marked layers, the cell corresponding to each component section is checked in the hierarchical detail table. In the specific implementation process, the number of F is related to the number of component sections, that is, the number of component sections plus 1. For example, in actual data analysis, the obtained hierarchical detail table is shown in Table 1: Hierarchical detail table;

[0052] Table 1: Layered details

[0053] (Number of the component section) ...... (Number of the component section) Layer 1 cut surface ...... The hth slice

[0054] By building a layered detailed list, the position of the component parts corresponding to each component section in the three-dimensional drawing in the three-dimensional original model can be roughly marked, thereby assisting users or designers to understand the surface and inside relationship of each component part corresponding to the three-dimensional drawing, which helps users or designers to improve the efficiency of data acquisition when designing based on three-dimensional drawings, thereby improving work efficiency.

[0055] The multi-component association module is used to obtain the same-level associated parts and cross-level associated parts of each component part based on the original 3D model and the hierarchical detailed list; based on the same-level associated parts and cross-level associated parts, generate the associated detailed list of each component part;

[0056] The multi-component association module includes a component association analysis unit, and the component association analysis unit is configured with a component association analysis strategy. The component association analysis strategy includes:

[0057] For any component part P, the parts connected to the component part P are obtained based on the 3D original model and recorded as model parts; for any model part, when the model part is a component part, the model part is recorded as an associable part of the component part P;

[0058] For any component section Q, the component sections adjacent to the component section Q in the three-dimensional drawing are recorded as adjacent sections of the component section, and the component parts corresponding to all adjacent sections of the component section are recorded as the associable parts of the component parts corresponding to the component section Q;

[0059] Get the associated parts of all component parts;

[0060] For any associable part C of any component part, when the number of layers marked on the component section corresponding to the component part is the same as the number of layers marked on the component section corresponding to the associable part C, the associable part C is recorded as the same-level associable part of the component part; when the number of layers marked on the component section corresponding to the component part is different from the number of layers marked on the component section corresponding to the associable part C, the associable part C is recorded as the cross-level associable part of the component part;

[0061] In the specific implementation process, by dividing the associable parts of the component parts into same-level associated parts and cross-level associated parts, the parts related to the component parts can be divided in terms of levels, that is, the parts of the same layer are classified into one category, and the parts of different layers are classified into one category, which helps to assist users or designers to understand the spatial structure of the 3D original model in the direction of the 3D drawing in subsequent analysis;

[0062] A table of 3 rows × F columns is created and recorded as an associated detail list, wherein the leftmost column of the associated detail list is filled with the same-level associated parts and cross-level associated parts from top to bottom except the first cell, and the top row of the associated detail list is filled with the numbers of the component sections corresponding to each component part from left to right except the leftmost cell; based on the numbers of the component sections corresponding to all component parts, the same-level associated parts and cross-level associated parts, the same-level associated parts and cross-level associated parts corresponding to each component part are filled in the cells of the associated detail list;

[0063] In the specific implementation process, such as in actual data analysis, the obtained association detail table is shown in Table 2: Association Detail Table;

[0064] Table 2: Related details table

[0065] (Number of the component section) ...... (Number of the component section) Same level related parts Cross-level related parts

[0066] By organizing the same-level associated parts and cross-level associated parts corresponding to all component parts in the associated details list, it is helpful for users and designers to obtain the association relationship between each component part and other component parts in the 3D drawing based on the details list after obtaining the details list of the 3D drawing later, thereby improving users and designers' understanding of the 3D drawings and their work efficiency when working based on the 3D drawings.

[0067] The nested detail list generation module is used to generate a conventional detail list of a three-dimensional drawing based on all component parts, and record the nested table obtained by associating the conventional detail list, the layered detail list and the associated detail list as the detail list of the three-dimensional drawing;

[0068] The detailed table nested generation module includes a general table generation unit, and the general table generation unit is configured with a general table generation strategy. The general table generation strategy includes:

[0069] Obtain the part number, quantity and weight of all component parts, create a table of F rows × 4 columns, and record it as a general detailed table, wherein the leftmost column of the general detailed table is filled with the part names of all component parts from top to bottom except the top cell, and the top row of the general detailed table is filled with the part number, quantity and weight from left to right except the leftmost cell; fill in the corresponding data in the general detailed table based on the part number, quantity and weight of all component parts;

[0070] In the specific implementation process, such as in the actual data analysis, the conventional detailed list obtained is shown in Table 3: Conventional detailed list;

[0071] Table 3: General details

[0072] Part Number quantity weight (Part name of component part) ...... (Part name of component part)

[0073] In the specific implementation process, the columns in the general detailed list can be added, deleted or modified according to the data of the components and parts actually obtained, so as to ensure that the general detailed list can cover the basic data such as the size data and quantity data of all components and parts;

[0074] The conventional detail list, the layered detail list and the associated detail list are associated, and the resulting table is recorded as the detail list of the three-dimensional drawing;

[0075] The association method is as follows: add a new column in the regular detail table, record it as the layer column, fill in the number of layers in the top row of the layer column, fill in the corresponding sections of each component part in the layer column based on the cells checked in the layered detail table, where the sections include the 1st layer section to the hth layer section; in the leftmost column of the regular detail table, based on the associated detail table, mark the same-level associated parts and cross-level associated parts of each component part with connection lines;

[0076] In the specific implementation process, the detail list of the three-dimensional drawing is obtained by associating the conventional detail list, the layered detail list and the associated detail list. On the basis of ensuring that the basic data of each part is included in the detail list, the parts associated with each part and the parts associated with each part and on the same layer or different layers can be clearly marked. This helps to improve the data analysis efficiency of users or designers based on the association relationship of each component when they perform data analysis based on the three-dimensional drawing detail list.
