[0045] The following is an explanation of the terms that may be involved in this application, as follows:

[0046] CAD (Computer-Aided Design): refers to the use of computers and their graphic equipment to help designers perform design work.

[0047] NX: Formerly known as UG, the full name is Siemens NX, which is a large-scale integrated system of CAD / CAE (Computer-Aided Engineering) / CAM (Computer-Aided Manufacturing) for product design, engineering and production development launched by Siemens.

[0048] Figure 1 1 is a flow chart of an auxiliary design method according to an embodiment. The auxiliary design method can be implemented in software and / or hardware. In this embodiment, the execution subject of the auxiliary design method is a computer device as an example. Figure 1 As shown, the auxiliary design method of the embodiment of the present application includes the following steps:

[0049] S1, in response to receiving a start instruction of the design software, start the auxiliary design interface to obtain a preset operation.

[0050] In this embodiment, the design software and the auxiliary design tool are started in association. When the user starts the design software, the auxiliary design interface of the auxiliary design tool will automatically start so that the user can set the preset operation. Specifically, a special plug-in or extension can be developed, which can be loaded when the design software is started and automatically open the auxiliary design interface of the auxiliary design tool. It is also possible to create a composite shortcut containing two application startup paths, first start the design software, and then start the interface of the auxiliary design tool. It is also possible to set an event listener at the operating system level, and when the design software is detected to be started, the startup of the auxiliary design tool is triggered by programming means. Of course, it is also possible to add an option to the startup interface of the design software so that the user can choose whether to start the auxiliary design tool.

[0051] S2, acquiring or generating a target template and a first design parameter of the target template according to a preset operation.

[0052] The preset operation can be an operation such as inputting, selecting, and moving the target model in the interactive area of ​​the auxiliary design interface. The user performs the preset operation in the auxiliary design interface to obtain or generate a target template and a first design parameter corresponding to the target template. Among them, the template refers to the basic geometric figure used to build the model, which has a first design parameter. The design parameter refers to the specific value or attribute used to define or adjust the design scheme during the design process. The target template is a specific template selected or input by the user. The model refers to the specific design content, that is, the actual three-dimensional geometry or two-dimensional graphics, such as mechanical parts, building structures, circuit boards, etc. The target model is a specific geometric figure designed by the user based on the target template.

[0053] S3, receiving an adjustment operation for the first design parameter, adjusting the first design parameter according to the adjustment operation, and obtaining a second design parameter for generating a target model and a constraint relationship between the second design parameter.

[0054] S4, sending the target template, the second design parameter and the constraint relationship between the second design parameter to the design software, so that the design software generates a target model according to the target template, the second design parameter and the constraint relationship between the second design parameter.

[0055] The user can adjust the first design parameter according to the design requirements in the auxiliary design interface to obtain the second design parameter and the constraint relationship between the second design parameter. The second design parameter can be used as the design parameter for generating the target model. Then, the auxiliary design tool sends the target template, the second design parameter and the constraint relationship between the second design parameter to the design software, so that the design software can automatically generate the target model required by the user.

[0056] The assisted design method of the embodiment of the present application can simplify the design process, help users quickly start design tasks through preset operations and automatic template generation, and realize personalized design by adjusting parameters by users, and finally generate customized final products by design software. The assisted design method of the embodiment of the present application is particularly suitable for scenarios that require a large number of repetitive design tasks, or models with complex parts and parameters between parts that are interrelated, and can improve design efficiency and quality.

[0057] In some embodiments, acquiring or generating a target template and a first design parameter of the target template according to a preset operation includes:

[0058] An acquisition instruction is determined according to a preset operation, and a target template, a first design parameter corresponding to the target template, and a constraint relationship between the first design parameters are acquired from a preset template set.

[0059] As an implementation of this embodiment, for a target template that already exists in a preset template set, an instruction to obtain the target template can be determined based on the user's input or selection operation in the auxiliary design interface, and then the target template can be obtained from the preset template set. The preset template set can be stored in a database, and the database also synchronously stores the first design parameters corresponding to each target template and the constraint relationship between the first design parameters.

[0060] Preferably, the first design parameters and constraint relationships that may be used for parametric design in each template can be stored in a structured manner in a database or text in the form of expressions, and the template name and the corresponding expression data can be associated in a prescribed naming method so as to quickly and accurately obtain the target template and corresponding design parameters required by the user.

[0061] In some embodiments, before determining to obtain the instruction according to the preset operation, the auxiliary design method further includes:

[0062] Create a database;

[0063] Obtaining a preset template set according to a plurality of part models and an assembly model of the plurality of part models;

[0064] Obtaining a design parameter set according to design parameters and constraint relationships of multiple part models and assembly models;

[0065] Establishing a corresponding relationship between each template in the preset template set and a first design parameter in the design parameter set, as well as a constraint relationship between each design parameter;

[0066] The preset template set and the design parameter set are stored in a database.

[0067] As an implementation method of this embodiment, by creating a database, the preset template set and design parameters can be stored in the same database. Specifically, for structural parts with complex parts, all part models and multi-part assembly models can be stored as parametric templates to form a preset template set for easy management and reuse. For each parametric template, identify the parameters that may be used for parametric design, such as size, shape, material properties, etc. At the same time, record the constraint relationship between these design parameters, that is, the mutual dependence and influence relationship between them. Design parameters and their constraint relationships are usually converted into mathematical expressions and stored in a database or text file in a structured manner.

[0068] The relevant parameters that can be used for parametric design models are stored and managed in the form of library tables. Especially for multi-part-level parametric models, the parameter settings of the entire model can be easily and intuitively viewed, allowing designers to have a more comprehensive understanding of the specified design requirements of the entire parametric model, facilitating subsequent design.

[0069] In some embodiments, acquiring or generating a target template and a first design parameter of the target template according to a preset operation includes:

[0070] According to the preset operation, a reference model and a third design parameter of the reference model are obtained;

[0071] A generation instruction is determined, a target template is generated according to the reference model, and a first design parameter of the target template is generated according to the third design parameter.

[0072] As an implementation of this embodiment, for a target template that is not stored in the preset template set, a new target template can be generated based on a reference model. Specifically, the user can enter the path of the reference model in the auxiliary design interface, and the reference model can be directly opened according to the path. Determine the generation instruction of the target template, generate a parameterized target template based on the reference model, and determine the first design parameter of the target template according to the third design parameter of the reference model. In this way, a new target template can be quickly created based on the reference model to design other target models using the target template.

[0073] In some embodiments, before receiving an adjustment operation for the first design parameter, the auxiliary design method further includes:

[0074] The first design parameters are displayed on the auxiliary design interface according to a preset order.

[0075] As an implementation method of this embodiment, after obtaining or generating the target template, the target template and its design parameters can be displayed simultaneously in the auxiliary design interface. Specifically, the first design parameters can be arranged in sequence in the auxiliary design interface by type. For example, the size parameters of the template are displayed first, followed by the shape parameters, and finally the material properties. The effect of each design parameter on the target template is displayed in a graphical manner, such as instantly updating the appearance of the target template when the size is changed. In this way, users can perform design work more intuitively, and can quickly iterate the design to improve work efficiency.

[0076] In some embodiments, the adjustment operation includes a modification operation and / or a movement operation on the first design parameter, and adjusting the first design parameter according to the adjustment operation includes at least one of the following:

[0077] modifying the type and / or value of the first design parameter according to the modification operation;

[0078] The constraint relationship of each design parameter in the first design parameter is modified according to the moving operation.

[0079] As an implementation of this embodiment, the type and value of the design parameter can be directly modified in the auxiliary design interface, such as by dragging a slider, inputting a value, or selecting an option from a drop-down menu.

[0080] As an implementation method of this embodiment, the relative position or distance between different design parameters can be adjusted by dragging and moving to update the constraint relationship between these design parameters. Exemplarily, the model MAIN displayed in the auxiliary design interface includes two parts A and B. Among them, MAIN contains parameters M1 and M2, part A contains parameters A1 and A2, and part B contains parameters B1 and B2. Drag parameter M1 to parameters A1 and B1, and drag parameter M2 to parameters A2 and B2. At the same time, modify the value behind the parameter of A2 to M2 / 4, and modify the value behind the parameter of B2 to M2 / 2. After the modification is completed, click OK, and the auxiliary design tool will associate parameter M1 with A1 and B1, and parameter M2 with A2 and B2. At this time, the specific values ​​of the A1 and B1 parameters are the values ​​of parameter M1, the value of the A2 parameter is the value of the M2 parameter divided by 4, and the value of the B2 parameter is the value of the M2 parameter divided by 2. In this case, the values ​​of parameters A1, B1, A2, and B2 do not need to be manually modified, and the values ​​of parameters A1, B1, A2, and B2 can be automatically modified by directly controlling the values ​​of parameters M1 and M2.

[0081] In some embodiments, the auxiliary design method further includes:

[0082] Verifying the second design parameter;

[0083] If the type and / or value range of the second design parameter is incorrect, an error prompt is generated.

[0084] As an implementation method of this embodiment, the second design parameter generated according to the first design parameter needs to be verified before being applied to generate the target model. Before the user attempts to modify or apply the design parameters, check whether these parameters meet the predefined standards or rules. If the type or value range of the second design parameter is incorrect, a corresponding error prompt is generated and the design parameter is prevented from being applied to the actual design until the user corrects the problem. The error prompt can be an error prompt message displayed at a fixed position or a parameter position of the auxiliary design interface, telling the user which design parameter has a problem and the cause of the problem.

[0085] Exemplarily, the auxiliary design interface has preset the basic framework of the watch strap template and the default design parameters. The design parameters are displayed in a preset order on the interface, such as the length of the watch strap first, followed by the width, and then the material options. The user tries to change the length parameter of the watch strap from 100mm to -20mm. It is detected that the value of the length parameter is a negative number, which does not meet the requirements, and an error message is displayed in the interface: "The length of the watch strap must be a positive number." The user notices the error message and changes the length parameter to a positive value, such as 120mm. After resubmitting the design parameters, it is detected that the length parameter now meets the requirements, so this parameter is applied to the design and the display effect of the 3D model is updated.

[0086] In some embodiments, sending the target template, the second design parameter, and the constraint relationship between the second design parameter to the design software includes:

[0087] Based on the interface program, the file format of the target template is converted into a first target format, and the file format of the second design parameter is converted into a second target format. The first target format and the second target format are file formats recognizable by the design software.

[0088] As an implementation method of this embodiment, the target template file and the second design parameter are obtained, and the template file and the design parameter are converted into a format recognizable by the design software through the interface program. The converted file is sent to the design software so that the design software automatically generates the target model.

[0089] Exemplarily, the file format of the target template is .dxf, and the file format of the second design parameter is .xlsx. When the design software is CAD, an interface program is used to convert the template in .dxf format into .dwg format that can be directly read by CAD, and the design parameter file in .xlsx format is converted into an internal data format or text format that can be recognized by CAD. A script or plug-in is used to send the converted file to CAD, and the design parameters are applied to update the model. Logic is defined in the script to handle constraint relationships to ensure that the relevant dimensions can be automatically adjusted to meet the constraint conditions when the design parameters are applied.

[0090] Please refer to Figure 2 Next, the auxiliary design method of this embodiment is specifically described in combination with the operation steps of the CAD design software and the auxiliary design tool.

[0091] After starting the CAD design software, you can start the CAD parametric auxiliary design tool (hereinafter referred to as "this tool") on the interface of the CAD design software. This tool can be used for parametric design on Siemens NX1899 version of CAD software, using the C# language that matches NX software development, and using the development tool Visual Studio 2015 for development.

[0092] This tool is developed to manage and store parametric templates and design parameter data using a text library.

[0093] The parametric template model name can be uppercase letters, lowercase letters, Arabic numerals, and the name length is not less than 8 characters, not greater than the maximum recognition length of the CAD software, and is unique in the library. The parameter name can be uppercase letters, lowercase letters, Arabic numerals, and special characters "_" and "-". The name length is not less than 4 characters, not greater than the maximum recognition length of the CAD software, and is unique in the same parametric template model. The parameter name has only one parameter value input port. When multiple parts in the same template use this parameter, the parameter is used and referenced in an associated manner.

[0094] Parametric templates are uniformly stored in a fixed folder. The parameter data of each parametric template model creates an Excel file with the same name as the template name. The parameter name that needs to be parametrically designed and the corresponding initial value, parameter type, parameter range, unit, and formula are written into the Excel file with the same name as the template parameter library file of the template, which is stored in the same fixed folder as the template.

[0095] On a computer with NX1899 software installed normally, place the executable program file in the "NXBIN" folder under the NX1899 installation path, create a program application button file (the file format is tbr), add the corresponding content that references the executable program file in the file, and then place the tbr file in the "UGII\menus" folder under the NX1899 installation path.

[0096] Start the CAD software NX1899, find and click the CAD parametric auxiliary design tool function button in the opened NX software.

[0097] In the auxiliary design interface, the designer selects or inputs the name or code of the model template to be parametrically designed. The auxiliary design tool will obtain the parameters and specific values ​​of the corresponding template from the parametric template and parameter library, and display them all on the auxiliary design tool operation interface, and the parameter values ​​can be modified. After the parameter operation is completed, the auxiliary design tool passes the model template name or code and the parameters to the CAD software, and the CAD software opens the template, applies the parametric engine to update the template parameters, renders the model, and generates a new parametric design model.

[0098] When you select or fill in the name of an existing parametric template for parametric design in the pop-up auxiliary design interface, click the "OK" button, and the NX software will automatically open the parametric template model. At the same time, the parametric design parameters corresponding to the model will be arranged in sequence by type in the auxiliary design interface, and the parameter values ​​are all preset initial values. You can modify the specific values ​​of each parameter according to the actual design needs, and click the "OK" button after the modification. The program will check the type and range of the input parameter values. When a parameter value does not meet the requirements, a prompt box will pop up to prompt the wrong parameter. Until the parameters meet the set requirements, click the "OK" button to generate a new parametric design model.

[0099] When the selected or filled in auxiliary design interface is not a template in the template library, but a specific model path, click the "OK" button, NX software will automatically open the model, and the design parameters corresponding to the model will be arranged in the auxiliary design interface in order by type, and the parameter values ​​are all actual values ​​of the model. You can drag each parameter to perform association operations according to the actual design needs. The value of the associated referenced design parameter will directly use the value of the associated parameter, and will be changed synchronously with the associated parameter to associate the parameter value, and the value of the associated parameter can no longer be manually modified independently (the associated parameter cannot be modified, but the associated parameter has an associated parent parameter, which can be modified). You can also modify the specific values ​​of each parameter according to the actual design needs, and click the "OK" button after the modification is completed. The program will check the specific model file name, the type and range of the input parameter value. When a parameter value does not meet the requirements, a prompt box will pop up to prompt the wrong parameter. Until the parameters meet the set requirements, click the "OK" button to generate a new parametric design model, and store the model and parameters as new parametric model templates and parameters in the parametric template and parameter library.

[0100] In the absence of a parametric template, the tool can first generate a "temporary parametric template" based on the current model. This temporary parametric template lists the corresponding parameter input fields based on the various parameters in the module, and there is no constraint relationship between the part parameters. At this time, you can directly use this "temporary parametric template" to directly modify the model parameters, or you can first manually set (based on user-friendly drag-and-drop operations) the association of different parameters in the "temporary parametric template" interface, and then save (generate) the parametric template corresponding to the parameter association, and then fill in the parameters that the user needs to modify based on this newly generated parametric template, and finally modify the model parameters. By combining the design and generation of parametric templates and model modification into one, you can modify the parameters of the existing model and create a new parametric template at the same time without a parametric template in advance.

[0101] In the embodiment of the present application, because the parametric template corresponds to the specific NX model, only the auxiliary design tool is needed to complete the parameter association setting and parameter modification. The user does not need to use the NX software to perform professional operations. The parameter association setting method and parameter modification method of the auxiliary design tool based on parametric design are more convenient and more friendly to non-professional users than the prior art method directly based on NX software.

[0102] From the above, the auxiliary design method of the embodiment of the present application, in response to receiving the start instruction of the design software, starts the auxiliary design interface to obtain the preset operation; obtains or generates the target template and the first design parameter of the target template according to the preset operation; receives the adjustment operation for the first design parameter, adjusts the first design parameter according to the adjustment operation, obtains the second design parameter for generating the target model and the constraint relationship between the second design parameter; sends the constraint relationship between the target template, the second design parameter and the second design parameter to the design software, so that the design software generates the target model according to the constraint relationship between the target template, the second design parameter and the second design parameter. The technical solution of the present application determines the template based on the auxiliary design interface, and automatically generates the model according to the design parameters and constraint relationship corresponding to the template, which simplifies the design process, reduces the error rate, and improves the overall work efficiency.
