Description

  The present invention relates to a technique for supporting dimension confirmation of 3D model shape data in 3D CAD data, and in particular, outputs / non-specific features (holes, fillets, etc.) in 3D CAD data by specifying conditions. The present invention relates to a technique for supporting dimensional confirmation by performing output control and generating image data for dimensional confirmation of 3D model shape data.

  In designing a product or the like, it is common to create 3D model shape data using 3D model creation support software (hereinafter referred to as 3D CAD). An examiner or approver who is different from the creator confirms whether the three-dimensional model shape data created using the three-dimensional CAD is created with the correct dimensions. For example, by confirming the dimension value of the two-dimensional drawing shape data related to the three-dimensional model shape data, it has been confirmed that the three-dimensional model shape data has been created with the correct dimensions. In addition, the 3D model shape support data used by the creator for creating the 3D model shape data is opened and confirmed.

  Patent Document 1 discloses a technique for removing features of three-dimensional CAD data according to accepted conditions. In the present invention, data that meets the conditions included in a drawing (three-dimensional model shape data) created by three-dimensional CAD due to a design change that frequently occurs particularly in the initial stage of design is removed. We are trying to improve efficiency.

  However, the conventional confirmation method is inefficient because the creator and examiner need to visually measure the dimensions. In addition, when there are many items that need to be confirmed, there is a risk that an artificial mistake of missing a mistake will occur. Moreover, when confirming with 3D model creation assistance software, naturally it is necessary to learn the operation of the software.

  When confirming the dimension value of a feature, it is easily confirmed by applying the technology disclosed in Patent Document 1 and performing output control (display on a display or print output) of a feature that meets the conditions. It will be possible. For example, by inputting the dimension of a feature as a condition and controlling the display / non-display of the feature that matches the condition on the display device, the examiner and the approver can easily confirm the correctness of the dimension of the feature. Become. However, Patent Document 1 does not mention any confirmation processing.

The present invention has been made to solve the above problems, the features with conditions Therefore the correct dimension values for the dimension values of the features contained in the three-dimensional model shape data confirms correct or not When performing suppression, it is possible to easily confirm the dimension value of the feature of the 3D model shape data by generating an image according to whether or not the suppression is performed while maintaining suppression of the feature due to other conditions. It aims at providing the technique for.

In order to solve the above-described problem, the information processing apparatus of the present invention has the following configuration. That is, the information processing apparatus supports the confirmation of the dimension value of the feature of the three-dimensional model shape data, and is a suppression condition for confirming whether or not the dimension value of the feature is correct. A first receiving unit that receives an input of a plurality of suppression conditions of a feature including a type of a feature to be performed and an allowable range of a correct dimension value of the feature, and a feature of the three-dimensional model shape data is the first receiving unit. The type of the feature included in the suppression condition for which the input is accepted and a determination unit that determines whether the feature size and the allowable range of the correct dimension value are met for each suppression condition, and the type of the feature included in the suppression condition by the determination unit And a first image after suppression of features having correct dimension values determined to meet the correct dimension value tolerance, and Generating means for generating a second image before performing the suppression of the features for each of the suppression condition, whether the dimension value of the feature is correct so as to confirm to the user, for each of the suppression condition by the generation means Display means for comparing and displaying the generated first image after suppression and second image before suppression for each suppression condition so that a feature having a correct dimension value suppressed based on the suppression condition can be identified. The first accepting unit further includes, together with the suppression condition, the suppression of the feature performed based on the suppression condition, and the generation unit displays the first image after suppression based on the other suppression condition. A feature suppression maintenance designation indicating whether or not to maintain even when generating is received for each suppression condition, and the generation means maintains the suppression of the feature by the feature suppression maintenance designation of one suppression condition. When the first image is generated based on the other suppression condition, the suppression of the feature performed based on the one suppression condition is maintained in the form of maintaining the other suppression condition. When generating the first image based on another suppression condition when the feature suppression maintenance designation of one suppression condition is not to maintain the suppression of the feature, A first image based on the other suppression condition is generated in a form in which the suppression of the feature performed based on the one suppression condition is cancelled .

In order to solve the above-described problem, a method for controlling an information processing apparatus according to the present invention has the following configuration. That is, a control method for an information processing apparatus that supports confirmation of a dimension value of a feature of 3D model shape data, wherein the first receiving unit of the information processing apparatus determines whether the dimension value of the feature is correct. A first receiving step for receiving input of a plurality of suppression conditions for a feature including a type of a feature whose dimension value is to be confirmed and an allowable range of a correct dimension value of the feature; The determination unit of the processing device determines whether or not the feature of the three-dimensional model shape data matches an allowable range of a feature type and a correct dimension value included in the suppression condition received in the first receiving step. The determination step for determining for each suppression condition, and the generation unit of the information processing apparatus include a fee included in the suppression condition in the determination step. The first image after the suppression of the feature having the correct dimension value determined to match the tolerance type of the type and the correct dimension value, and the second image before the suppression of the feature are A generation step generated for each suppression condition, and a display unit of the information processing apparatus after the suppression generated for each suppression condition in the generation step so that the display unit of the information processing apparatus confirms whether or not the dimension value of the feature is correct. A display step of comparing and displaying the first image and the second image before suppression for each suppression condition so that a feature having a correct dimension value suppressed based on the suppression condition can be identified, and The first receiving step further includes the suppression of the feature performed based on the suppression condition together with the suppression condition, after the generation step is suppressed based on the other suppression condition. A feature suppression maintenance designation indicating whether to maintain even when generating one image is received for each suppression condition, and the generation step maintains the suppression of the feature by the feature suppression maintenance designation of one suppression condition. When the first image is generated based on the other suppression condition, the suppression of the feature performed based on the one suppression condition is maintained and the first image based on the other suppression condition is maintained. When the feature suppression maintenance designation of one suppression condition does not maintain the suppression of the feature, when generating the first image based on the other suppression condition, A first image based on the other suppression condition is generated in a form in which the suppression of the feature performed based on the suppression condition is cancelled .

According to the present invention, when checking the 3D model shape data, by controlling the output / non-output of the features in the 3D model shape data according to the input suppression conditions, the correct dimension value can be obtained. It is possible to easily check the features that are possessed, and even if there are multiple suppression conditions , it is possible to receive the designation of whether to maintain suppression based on the suppression conditions for each suppression condition. It is possible to control whether the suppression is maintained or canceled even when the suppression is performed under the suppression condition, so that it is possible to reduce the confirmation work of the 3D model shape data and the reduction of confirmation omissions and mistakes. However, it can be expected to prevent the problem that the feature to be confirmed is already suppressed and the dimensional value cannot be confirmed .

  The condition file input field 701 is an input field for inputting the path of the feature suppression condition file. When the CPU 201 detects that this button is pressed, the “file designation” button 702 displays a file designation dialog box (not shown) on the display device 210 and accepts designation of a feature suppression condition file. The path of the file that has received the designation is input to the condition file input field 701. When the CPU 201 detects that the “Open” button 703 has been pressed, the file indicated by the path input in the condition file input field 701 is opened.

The created file is saved. The file name is, for example, “feature type” + “feature subtype” + “suppression condition”. The extension is set. When an unusable name character is included as a file name in the suppression condition or the like, the character is converted under a preset condition, and the file name is set.

When the CPU 201 detects that the execute button 708 has been pressed, the CPU 201 performs the processing after step S304 in FIG. 3 under the conditions input via this screen. When the CPU 201 detects that the end button 709 has been pressed, the display of this screen is ended. The above is the description of the feature suppression condition input screen shown in FIG.

  Returning to the description of FIG. After the processing in step S303 is completed, the CPU 201 performs the processing from step S304 to step S319 on all feature suppression condition data acquired in step S302 and stored in the RAM 202 as condition table data in step S303.

  First, in step S304, the suppression conditions (condition designation, feature type, feature subtype, range, suppression hold) set in the condition suppression data for processing to be processed are added to the confirmation data to be displayed on the display device. (Step S304). After that, among the features included in the three-dimensional model shape data, a feature matching the suppression condition for which the condition designation is checked is searched (step S305). Details of this processing will be described later with reference to FIG.

  After the processing in step S305 is completed, the processing from step S306 to step S309 is performed for all the display directions set in the condition data (specified in the display direction specification field 706 in FIG. 7). First, in step S306, a process for changing the display direction of the 3D model shape data to be confirmed is performed. The image data and display direction data in the designated direction before suppression are added to the confirmation data. Thereafter, when the creation of the confirmation material (electronic document) for the three-dimensional model shape data is instructed (YES in step S308), the designated display direction data and the image data before the feature suppression are prepared for creating the electronic document. Is stored in the RAM 202 or the external memory 211 (step S309). At this time, after changing the display direction using the display direction changing function provided in the CAD program 104-d, image data in a format such as TIFF or JPEG is also output using the electronic image data output function provided in the CAD program 104-d. The data is output and stored in the RAM 202 or the external memory 211.

  After the process from step S306 to step S309 is completed for all display directions specified in the condition data, the process proceeds to step S310, and it is determined whether there is data corresponding to the condition data in the search process of step S305 (corresponding Data present ?: Step S310). If it is determined that there is data corresponding to the condition data in the search process (YES in step S310), the process proceeds to step S311 and is detected (matches the condition data) under the control of the feature suppression program 104-e. Perform feature suppression processing. Then, the processing from step S312 to step S315 is performed for all display directions set in the condition data for the three-dimensional model recording data after the feature suppression. Since this process is substantially the same as the process from step S306 to step S309, detailed description is omitted.

  After the processing from step S312 to step S315, whether to cancel the suppression of the feature suppressed in step S311 is determined according to the suppression cancellation specification specified by whether or not the suppression cancellation check box 704-e in FIG. Step S316). If it is determined to cancel the suppression, the suppression of the feature performed in step S311 is canceled (step S317). It is determined whether or not creation of confirmation material (electronic document) for 3D model shape data is instructed (step S318). If it is determined that creation is instructed (YES in step S318), electronic document creation processing is performed. Is performed (step S319). Details of this processing will be described later with reference to FIG.

  Then, after the processing from step S304 to step S319 is completed for all the condition data, the confirmation data created by performing the processing of step S304, step S307, and step S313 is displayed on the display device 211 (step S320). .

  Thereafter, it is determined whether or not creation of confirmation material (electronic document) of the 3D model shape data is instructed by the condition data (step S321). If it is determined that the instruction is instructed (YES in step S321). Then, the electronic document data is printed out (step S322). The above is an example of the three-dimensional model shape confirmation process.

  Next, with reference to FIG. 4, the details of the process for searching for a feature that matches the feature suppression condition in step S305 in FIG. 3 will be described.

  First, in step S401, all the features included in the 3D model shape data to be confirmed are acquired. At this time, the information of each acquired feature is stored in the RAM 202 by substituting it into an array variable for managing feature data and the number of features into a feature number holding variable.

  Thereafter, the processing from step S402 to step 407 is performed on all the features acquired in step S401 and assigned to the array variable. First, the CPU 201 acquires k-th feature data (the initial value of k is 1) of the array variable (step S402), and determines whether the feature conditions set in the i-th condition data of the condition table are met. (Step S403). If it is determined that they match, the process proceeds to step S404, and feature subtype data is acquired. Further, the dimension value is also acquired (step S405).

  Thereafter, the feature subtype acquired in step S404 is compared with the feature subtype and range set in the condition data in step S405, and it is determined whether or not the condition subtype matches the condition set in the condition data (step S406). If it is determined in this determination process that the two match (YES in step S406), the feature data is stored in the RAM 202 or the external memory 211 as detected feature data that matches the condition data (step S407). After the process of step S407, or when it is determined NO in step S406, the counter variable k is incremented, and the process from step S402 to step S407 is performed on the kth feature data of the array variable. . The above is the details of the process for searching for a feature that matches the feature suppression condition in step S305 in FIG.

  Next, the details of the electronic document creation process shown in step S319 of FIG. 3 will be described with reference to FIG. This process is a process performed by the CPU 201 of the information processing apparatus 100.

  First, the CPU 201 loads the 3D model shape data confirmation material template file 104-c stored in the external memory 211 into the RAM 202 (step S501).

  FIG. 6 is a block diagram showing the configuration of the 3D model shape data confirmation material template file. The 3D model shape data confirmation document template file is created in a data format that can be handled by spreadsheet software.

  The 3D model shape data confirmation document template file includes a feature type input field 601, a feature subtype input field 602, a range input field 603, a creation date input field 604, a display direction input field 605, a pre-suppression image addition field 606, and a suppression. A post image addition field 607 is set, and information indicating how many rows and columns each input field / addition field is located is stored in the external memory 211 together.

  In the feature type column 601, the feature type set in the feature suppression condition data used when creating the three-dimensional model shape data confirmation material is input. Similarly, a feature subtype set in the condition data is input to the feature subtype input field 602, and a range is input to the range input field 603. In the creation date input field 604, a creation date when the 3D model shape data confirmation material is created is input.

  In the display direction input field 605, display direction information of image data before and after suppression is input. In the pre-suppression image addition field 606, image data before being suppressed with the condition data indicated by 601 to 603 is added. In the post-suppression image addition field 607, the image data after suppression by the condition data indicated by the above-mentioned 601 to 603 is added. The above is the description of the configuration of the 3D model shape data confirmation material template file.

  Returning to the description of FIG. When the process of step S501 is completed, the CPU 201 inputs the feature type, feature subtype, and range set in the condition data to the feature type input field 601, the feature subtype input field 602, and the range input field 603, respectively (Step S501). S502). In that case, each data is input into the place according to the information which shows how many rows and columns each input column.

  Thereafter, the image data before suppression stored in the RAM 202 in step S308 in the pre-suppression image addition field 606 and the image data after suppression stored in the RAM 202 in step S313 for all display directions specified in the condition data. They are added to the post-suppression image addition field 607 (steps S503 and S504, respectively). After all the processes are completed, the electronic document data file is stored in the external memory 211 (step S505). The above is the details of the electronic document creation processing shown in step S317 of FIG.

  Finally, with reference to FIG. 8, an outline of processing performed in the three-dimensional model shape confirmation processing shown in the flowchart of FIG. 3 will be described. In this description, reference numeral 800 in FIG. 8 denotes three-dimensional model shape data whose dimensions are to be confirmed. As shown in the figure, holes 801-a, 801-b, 801-c, 802-a, 802 are used as features. b and 803 are set. The holes 801-a, 801-b, and 801-c have a radius as a feature subtype and 20 mm as a dimension value. Similarly, it is assumed that 802-a and 802-b have a radius and dimension value of 30 mm as the feature subtype, and 803 has a radius and dimension value of 25 mm as the feature subtype. An example of correctness determination of the radius dimension value of the features 801-a to 801-c according to the present invention will be described with the surface on which the feature is set as the front. Here, 801-a to 801-c are assumed to have an allowable range of 20 mm ± 1 mm as a dimension value of the radius.

  Here, as feature condition data for confirming the dimension values of 801-a to 801-c, feature type = “hole”, feature subtype = “radius”, range = “19 ≦ dimension value ≦ 21”, It is assumed that the specified condition data is used when a front three-dimensional model shape data confirmation material is created as a display item.

  The CPU 201 generates a front image as shown at 810 in FIG. 8 by changing the display direction in step S306 in FIG. 3, and stores the generated image data in the RAM 202 (processing in step S309).

  Thereafter, in step S311, suppression processing is performed on all the features detected as matching the feature suppression condition data in step S305. The result is 820 in FIG. Here, if the dimension values of the features 801-a, 801-b, and 801-c are set correctly, all of them are suppressed, and as a result, image data that cannot recognize the feature is created. The image data created by this process is stored in the RAM 202 by the process of step S315 in FIG.

Thereafter, an electronic document for confirming the correctness of the dimension value of the feature is created in the process of step S319 in FIG. If the dimension values of the features 801-a to 801-c are set correctly, electronic document data as shown at 850 in FIG. 8 is generated. In this example, the image data before suppression of features and the image data after suppression are displayed in contrast .

  Here, by comparing and outputting the image data in the specified display direction before and after feature suppression, it is easier to recognize the suppressed feature, and the condition data used to suppress the feature is also By outputting together, the validity of the condition data can also be confirmed. The confirmation data to be displayed on the display device 210 in step S320 of FIG. 3 also has a configuration like 850 in FIG.

  According to the present invention, particularly when a plurality of features of the same type and size are set in the three-dimensional model shape data, the feature is added to the image data by suppressing / non-suppressing the feature based on the condition data. By controlling the output / non-output, it is possible to easily check the dimension value of the feature.

  The present invention can be implemented as a system, apparatus, method, program, storage medium, or the like, and can be applied to a system including a plurality of devices. You may apply to the apparatus which consists of one apparatus.
