Description

Technical Field

[0001] The present invention belongs to the technical field of three-dimensional design, and in particular relates to a feature rapid design method, device and storage medium based on feature standardization. Background Art

[0002] MDA design software supports feature design as well as parametric design. The designed features are inconvenient for non-feature designers to use. In recent years, the demand for feature rapid design methods based on MDA 3D design software has gradually increased, because this method can significantly shorten the design cycle and improve product quality. Extensive research and development work is currently being carried out in this field to explore more efficient and intelligent design methods. Traditional feature rapid design methods include copy and paste, template design, and parametric design. Some software will provide some official ways to reuse features or feature libraries, from which users can select existing features and reuse them in new designs.

[0003] The existing technology is troublesome to select features, and users need to be very familiar with the features. Most of the features used by each designer are created and used by themselves. Each designer has his own set of feature libraries. It is inconvenient to use someone else's feature library, which causes designers to redesign and waste time. In addition, design consistency is an important issue in large-scale product design. When using traditional methods for design, different designers may design the same feature inconsistently, resulting in differences in product appearance and performance. Summary of the invention

[0004] The present invention provides a method, device and storage medium for rapid feature design based on feature standardization, which extracts features from existing designs, and redesigns and calls features by establishing standardized feature definitions and a unified feature library, thereby avoiding designing features from scratch, greatly reducing the problem of repeated design, and ensuring that designers use the same features in the process of large-scale product design to achieve design consistency.

[0005] To achieve the above object, the present invention is implemented by adopting the following technical solutions: In a first aspect, the present invention provides a method for rapid feature design based on feature standardization, comprising: According to design requirements, select the required features from the unified feature library; According to the feature information of the design setting, the selected features are parametrically modified and inserted into the model; The method for obtaining the unified feature library includes: Parametric design of features from historical designs based on standardized feature definitions; Create features after parametric design; Store the created features into a pre-built unified feature library.

[0006] Optionally, the parametric design of the features in the historical design according to the standardized feature definition in the three-dimensional digital model software includes: The feature library dialog interface that triggers the feature agile design function for existing models; According to the design requirements, features in the existing model are selected in the feature library dialog interface, and detailed information of the features is standardized; Sets the model reference for the feature based on the reference required by the selected feature.

[0007] Optionally, the standardizing of the detailed information of the feature includes: Configure corresponding standardized parameter tables for each category feature; A parameter-driven relationship is established for key specification parameters in the parameter table.

[0008] Optionally, the creating of features after parameterized design includes: Select the model references required for feature placement in sequence; After the model reference is selected, the corresponding parameter driving relationship is found according to the feature detailed information, and the feature is parameter-driven; After the parametric drive is completed, the feature creation is completed.

[0009] Optionally, the unified feature library is a set of commonly used feature libraries divided according to feature categories; The storing the created features into a pre-built unified feature library includes: storing the created features into a common feature library path of a corresponding category.

[0010] Optionally, selecting a required feature from the unified feature library according to the design requirement includes: searching a common feature library of a category corresponding to the required feature according to the design requirement, and selecting a feature from the common feature library.

[0011] Optionally, the parameterized modification of the selected features and the insertion into the model according to the feature information of the design setting include: The current feature dialog interface is used to select the selected feature and trigger the feature parameter modification function; Compare the feature specification parameters in the current feature dialog interface with the feature information of the design setting. If they are consistent, no modification is required. If they are inconsistent, modify the feature specification parameters according to the feature information of the design setting.

[0014] In a fourth aspect, the present invention provides an electronic terminal, characterized in that it includes a processor and a memory connected to the processor, wherein a computer program is stored in the memory, and when the computer program is executed by the processor, the feature rapid design method based on feature standardization as described in any step of the first aspect is executed.

[0015] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: by providing a feature library and standardized feature definitions, the feature rapid design technology allows designers to reuse existing features in new projects, avoiding the time and energy consumption of designing from scratch.

[0024] The present invention will be further described below in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention.

[0025] Example 1

[0026] like Figure 1 As shown, this embodiment provides a feature rapid design method based on feature standardization, including:

[0027] Parametric design of features from historical designs based on standardized feature definitions;

[0028] Create features after parametric design;

[0029] Store the created features into a pre-built unified feature library;

[0030] According to design requirements, select the required features from the unified feature library;

[0031] According to the feature information of the design settings, the selected features are parametrically modified and inserted into the model.

[0032] The present invention establishes standardized feature definitions and a unified feature library. Through the standardized feature definitions, features designed by different designers can be added to the unified feature library, the feature library is intelligently managed, and common and favorite functions are supported. Feature information can be visually viewed, and the required feature library can be quickly found through various methods such as directories and keywords. After selecting a feature, the relevant parameters are set and the feature is quickly inserted into the model by selecting a reference. In addition, the invention also supports the modification of already defined features, thereby realizing the rapid design of features during model design, avoiding duplication of work and waste of time, and achieving design consistency in large-scale product design.

[0033] Example 2

[0034] Based on Example 1, this example also makes the following design.

[0035] In this embodiment, Figure 2 As shown in the figure, the steps for rapid parametric design of 3D model features are as follows: open a model; click the feature agile design function to pop up the feature library dialog box interface, as shown in Figure 5 ; Select a feature according to the design requirements, and a dialog box will pop up to display the feature details, such as Figure 6 ; Set the detailed information of the feature according to the design, such as standard / non-standard, specifications, etc.; Set the model reference corresponding to the feature according to the reference required by the selected feature; After the feature design is completed, generate the corresponding udf file with the suffix .gph.

[0036] like Figure 3 As shown in the figure, if the parameters need to be modified during the parametric design process, the steps for quickly modifying the 3D model features are as follows: select the features generated by the parametric design; click the feature parameter modification function; a dialog box pops up to display the currently used features and the specification parameters used in the features, such as Figure 7 ; Set detailed information of features according to the design, such as standard / non-standard, specifications, etc.; feature parameterization modification is completed.

[0037] In this embodiment, during parametric design, each feature corresponds to a configuration table. The feature will establish a parameter relationship drive for the key dimensions in the configuration table, and set multiple sets of preset values ​​for the key parameters according to national standards and industry experience. Figure 6 In the loading interface shown, multiple groups of preset values ​​are filled into the interface for users to choose from.

[0038] like Figure 4 As shown in the figure, the steps for feature creation after parametric design is completed are as follows:

[0039] 1. When placing features, you need to load the udf file corresponding to the feature quick design, and select the model references required for feature placement one by one;

[0040] 2. In the feature quick design interface, the user fills in and selects the specification parameters in the configuration table, finds the corresponding parameter driving relationship, and drives the features parameter-wise;

[0041] 3. After the parametric drive is completed, the feature creation is completed and the created feature is stored in the common feature library under its corresponding category.

[0042] When the design model needs to call a feature, the required feature library can be quickly found through various methods such as catalogs and keywords according to the design needs, and the feature library of the corresponding category can be browsed and viewed and a feature can be selected from it; based on the selected feature information, the feature quick design catalog option used by this feature is identified; the specifications set by the current user are captured through feature parameters, and the extracted data is displayed in the interface, where the displayed data includes schematic diagrams, references, standards, variables, etc., which are clear at a glance for users to use.

[0043] According to the detailed information of the designed features, modify the specification parameters of the features; after modification, click Finish to update the user-modified data to the feature parameters according to the relationship, and the feature parameterization modification is completed; then select the model reference corresponding to the modified parameters and insert it into the model.

[0044] In this embodiment, the features can be various geometric shapes, components, assembly methods, functional modules, etc. Through the rapid design technology of key features of three-dimensional digital models, new design variants and derivative products can be quickly generated. This technical patent includes rapid reuse of grooves, holes, threads, gears and other categories, based on standard structural features, rapid generation and adjustment, improving the work efficiency of designers and shortening the cycle from development to production.
