[0056] The technical solutions in the embodiments of the present invention are described clearly and completely below. 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.

[0057] refer to Figure 1 to Figure 2 , a CAD design drawing generation method, specifically comprising:

[0058] Collect solution documents according to the type and solution of engineering design;

[0059] Extract engineering parameters from the solution file and convert the engineering parameters into a JSON file according to a preset format;

[0060] Classify JSON files according to purpose, level or engineering characteristics to generate JSON configuration files of different levels;

[0061] Obtain user input information, merge the user input information with the engineering parameters in the JSON configuration files at different levels, and generate the final design parameter set;

[0062] The final design parameter set is read, and objects of corresponding types are drawn in the CAD software according to the parameter types and values, thereby generating a CAD design drawing.

[0063] In this embodiment, by collecting and converting the engineering parameters of the solution file into JSON format, data standardization and unification are achieved, the complexity and error rate of data processing are reduced, and JSON configuration files of different levels are generated hierarchically, making the design process more modular and easy to manage and maintain. The user input information and the engineering parameters in the JSON configuration file are automatically merged, which reduces manual intervention and improves design efficiency. The user is allowed to input information according to actual needs and merge it with the preset engineering parameters, making the design process more flexible and able to meet the personalized needs of different users. By drawing objects according to parameter types and values ​​in CAD software, the instant generation and modification of design drawings are achieved, and the response speed of the design is improved. JSON files are used as data exchange formats to ensure the accuracy and consistency of data during transmission and storage. The engineering parameters are hierarchically managed in the form of JSON files to facilitate subsequent data query, modification and reuse. The generated CAD design drawings can be updated and maintained based on a unified data source, reducing the risk of duplication of work and error propagation.

[0064] Preferably, converting the engineering parameters into a JSON file according to a preset format specifically includes:

[0065] Obtain the hierarchical and logical relationships between engineering parameters;

[0066] Establish a JSON structure based on the hierarchical and logical relationships between project parameters;

[0067] Use a text editor to write JSON code according to the determined JSON structure;

[0068] Assign project parameter data to the keys in the JSON code;

[0069] The assigned JSON code is saved as a file in JSON format to convert it into a JSON file.

[0070] In this embodiment, by obtaining the hierarchical relationship and logical relationship between the engineering parameters, the dependencies and associations between the parameters can be clearly understood, which provides a basis for establishing a reasonable JSON structure. The established JSON structure not only reflects the physical level of the parameters, but also reflects the logical connection between them, making data management more orderly and efficient; the JSON format, with its clear structure and concise syntax, makes the data easy to read and understand. Writing JSON code through a text editor can ensure the standardization and readability of the code, which is convenient for subsequent data processing and maintenance; the engineering parameter data is assigned to the keys in the JSON code, which realizes the separation of data and structure, so that there is no need to change the JSON structure itself when modifying the data, thereby improving the maintainability of the data. At the same time, the format standardization of JSON files makes data exchange between different systems simple and direct, reducing the difficulty of data migration and maintenance; the data transmission efficiency of the JSON format is high and it is easy to compress, which can reduce the amount of data in network transmission and increase the exchange speed, which is particularly important for design teams and partners who need to frequently exchange design data.

[0071] It should be noted that the preset format follows the format of "parameter name: value".

[0072] Preferably, the JSON files are classified according to the purpose, grade or engineering characteristics to generate JSON configuration files of different levels, specifically including:

[0073] Classify and organize JSON files according to purpose, level or project characteristics to obtain JSON files of different levels;

[0074] According to the classification results, create a corresponding JSON configuration file for each level;

[0075] Define the relationship between JSON configuration files to generate JSON configuration files at different levels.

[0076] In this embodiment, by classifying and organizing JSON files according to purpose, level or engineering characteristics, various complex engineering design requirements can be flexibly handled. This hierarchical method enables the system to adapt to engineering projects of different types and sizes, improving the flexibility and scalability of the system; creating a corresponding JSON configuration file for each level realizes modular design. This design method makes the system easier to maintain and upgrade, because the configuration files of each level can be modified and updated independently without affecting the configuration of other levels; defining the relationship between JSON configuration files helps to achieve parameter reuse. For parameters used in multiple projects, they can be placed in a higher-level configuration file, thereby reducing repeated definitions in lower-level configuration files and effectively reducing data redundancy; hierarchical JSON configuration files enable designers to find the required parameters more quickly when performing CAD design, and select and adjust them according to actual needs. This efficient parameter management method helps to improve design efficiency and accuracy.

[0077] Preferably, the obtaining of user input information, merging the user input information with engineering parameters in different levels of JSON configuration files, and generating a final design parameter set specifically includes:

[0078] According to the predefined hierarchical structure, read the JSON configuration files at each level in turn;

[0079] Match the information entered by the user with the parameters in the JSON configuration files at all levels to find the corresponding parameter items;

[0080] Merge parameters in JSON configuration files at different levels according to preset priority rules;

[0081] The merged parameters are organized into a structured final design parameter set.

[0082] In this embodiment, the information input by the user is combined with the standard parameters in the predefined JSON configuration file, so that the design drawing can accurately meet the specific needs of each project, achieving a high degree of personalization and customization; through the predefined hierarchical structure and priority rules, the system can automatically and quickly merge the parameters in the JSON configuration files at all levels, reducing the possibility of human intervention and errors, and improving the efficiency and accuracy of parameter merging; the technical solution supports the flexible addition and reduction of JSON configuration files at different levels, as well as the flexible specification of the location and purpose of different functional configuration files, so that the system can adapt to various complex and changeable engineering requirements, and improve the flexibility and adaptability of the system; when the parameters input by the user are detailed and appropriate enough, the system can directly generate the final design drawing based on these parameters and the predefined configuration file, realizing the full automation from data input to design drawing output, and greatly improving the design efficiency; by reducing human intervention, especially reducing the direct modification of the design drawing, the technical solution helps to reduce design errors caused by human factors and improve the quality and reliability of the design drawing.

[0083] It should be noted that the information input by the user includes but is not limited to the following categories:

[0084] 1. Roof and obstacle parameters:

[0085] Roof sketch data: including basic information such as the shape and size of the roof.

[0086] Obstacle location and height: such as the location coordinates and height of watchtowers, trees, and other buildings.

[0100] Preferably, the method further comprises a bill of materials generation step, specifically comprising:

[0101] In the process of generating CAD design drawings, different design objects are divided into different layers according to the type of design objects;

[0102] Assign each layer a clear name and ID that corresponds to the object type defined in the BOM configuration file;

[0103] Obtain a bill of material configuration file, wherein the bill of material configuration file includes requirement templates for different materials;

[0104] Read data from CAD layers;

[0105] Calculate the required quantity of each material based on the data in the CAD layer and the requirements in the BOM configuration file;

[0106] Fill the calculated material requirement data into the Excel table according to the template requirements of the bill of materials configuration file to generate the bill of materials.

[0107] In this embodiment, by automatically dividing different design objects in the CAD design drawing into different layers, and automatically generating a bill of material requirements based on the data of these layers and the bill of material configuration file, work efficiency is greatly improved. Designers do not need to manually calculate or fill in material information, which reduces the possibility of human errors and accelerates the process from design to procurement. Since the bill of material generation process is based on the strict matching and calculation of precise CAD layer data and bill of material configuration files, the generated bill of material requirements has a high degree of accuracy, which helps to ensure that the material supply during the construction process is completely consistent with the design requirements and avoids construction delays or cost waste due to insufficient or excessive materials. The bill of material configuration file can be flexibly configured according to different engineering plans and requirements, including material type, coding, filling location, etc. This flexibility enables the system to adapt to a variety of different engineering scenarios and improves the versatility and scalability of the system. Since each material requirement can be traced back to a specific design object in the CAD layer, the entire bill of material generation process has good traceability, which helps to quickly locate the source of the problem in the subsequent construction or audit process and take corresponding solutions.

[0108] Preferably, the method further comprises a three-dimensional model generating step, specifically comprising:

[0109] Extract the plane coordinates, dimensions and other relevant parameters of all objects that need to be converted into 3D models from 2D CAD design drawings;

[0110] According to the plane coordinates in the two-dimensional design drawing and the height information of the object, the key point coordinates of each object in the three-dimensional space are calculated;

[0111] Use the Three.js engine to create each object in the 3D model based on the key point coordinates;

[0112] Combine all created 3D objects into a complete 3D model.

[0113] In this embodiment, by extracting key parameters from the two-dimensional CAD design drawing and generating a three-dimensional model, designers and customers can more intuitively view and understand the three-dimensional effect of the design scheme, thereby making more accurate decisions and modifications. The three-dimensional model can more comprehensively display the design details, reducing the misunderstanding and communication costs caused by the limitations of the two-dimensional drawings. The three-dimensional model generation step ensures the continuity from design to construction. Construction personnel can more accurately understand the design intent by viewing the three-dimensional model, thereby improving the construction quality and efficiency; by converting the x, y, and z coordinates of CAD into the coordinate system of the Three.js engine and generating an HTML file, the universality and convenience of the three-dimensional model on different platforms are achieved. Whether it is a computer, a mobile phone, or through social media such as WeChat, users can easily browse and share the design results; the use of modern web technology (Three.js) to generate a three-dimensional model reflects the effective combination of CAD design and modern web technology, and promotes technological innovation and progress in the design industry.
