Description

  The present invention relates to an information processing apparatus, an information processing system, a control method thereof, and a program.

  In the manufacturing industry, the introduction of 3D CAD (Computer Aided Design / hereinafter referred to as CAD) software that edits a 3D model in the design process is progressing, while in the manufacturing process CAM (Computer Aided Manufacturing / hereinafter referred to as CAM). Efforts are being made to efficiently define the processing of products by applying model files to software. Various position information and dimensional information are stored in the model file. If the CAD software and CAM software are not compatible enough, the dimensions for creating the model file and the tolerance information included in the dimensions can be obtained from the CAD software. It may not be possible to share correctly with CAM software.

  After printing the model file information on the 2D drawing with CAD software and importing the model file on the CAM software side, the user of the design process can check the 2D drawing and go to any part of the model file on the CAM software. By inputting the dimensions, accurate information on the dimensions can be recorded in the model even in the CAM software, but the input operation is laborious.

  However, depending on the combination of CAD software and CAM software, dimension information cannot be shared, but color information may be normally shared (captured). In order to simplify the above-described input work, for example, with respect to the hole size, the color of which type of hole is to be colored is determined in advance between the user of the design process and the user of the manufacturing process. The model file is shared with the CAM software after coloring each hole type on the side. By defining a color that is compared with a certain processing definition on the CAM software side, an effect equivalent to the processing definition applied to a portion colored by the above-described coloring operation can be obtained.

  For example, Patent Document 1 describes that the color of the model itself is changed according to attribute information such as the weight and material of the model itself.

JP 2003-271777 A

  However, for example, holes created and defined by features (holes placed in the model) are different from the model itself, so the user can manually change the color of the hole separately from the color setting of the model itself. You have to do the coloring operation and work. Regardless of whether the designer or the processor performs the coloring work, if there are a large number of colored portions, it takes time and effort accordingly.

An object of the present invention is to provide a mechanism capable of easily changing the color of a portion whose shape has been changed in a three-dimensional model .

The present invention relates to a program for controlling an information processing apparatus comprising a three-dimensional model and storage means for storing a condition for determining the color of a portion whose shape has been changed based on information for changing the shape of the three-dimensional model. In the three-dimensional model , the information processing apparatus is configured to manually change a color of a part whose shape has been changed based on the information by a manual operation of a user instructing the color change, setting means for setting whether to perform either an automatic setting performed automatically according to the additional of the information, when it is said and are manually set manual operation by the setting unit, the condition is satisfied the information If the shape changed portion subjected colors determined by those the condition, the automatic setting has been and the satisfying said information is added based on, on the information Is a program for functioning as a control means for controlling so you with a color which is determined by the condition is changed portion shape Zui automatically.

According to the present invention, it is possible to provide a mechanism that can easily change the color of a portion whose shape has been changed in a three-dimensional model .

The above is the description of FIG.

  Here, the affinity between CAD software and CAM software is inadequate, and it is not possible to read out all the information of CAD files created and edited with CAD software with CAM software. It can be read and displayed / displayed on the display screen.

  <First Embodiment>

  The processing flow of the present invention will be described below with reference to FIGS. 4 to 7 are executed by the CPU 201 of the PC 100 using the function of CAD software or a coloring tool installed in the PC 100.

  First, with reference to FIG. 4, the outline of the processing in the embodiment of the present invention will be described.

  In step S401, a 3D model to be processed is displayed on the CAD software by accepting a command launch process by the operator, and the coloring tool is launched by accepting a launch operation of the coloring tool on the CAD software screen. (Step S401).

  The activated coloring tool creates and stores a color arrangement table 800 shown in FIG. 8 on an external memory. When a predetermined external data file (for example, a file stored in a predetermined storage area of the PC 100 managed by the coloring tool) that can import information into the color arrangement table 800 can be acquired, the external file is acquired. Then, the information in the external file is stored in the color arrangement table 800. If there is no external file, leave each item blank.

  Here, with reference to FIG. 8, an example of the configuration of the color arrangement table in the embodiment of the present invention will be described.

  The color arrangement table 800 stores a record number No. 801, a hole type 802 that stores a hole type, a through hole diameter Min 803 that stores a lower limit value of the through hole diameter of the hole, and a through hole that stores an upper limit value of the through hole diameter of the hole. Bore diameter Max804, counterbore diameter Min805 that stores the lower limit of counterbore diameter when the hole type is counterbore, counterbore that stores the upper limit of counterbore diameter when the hole type is counterbore Counterbore depth Min 807 for storing the counterbore depth when the hole diameter is Max806, the hole type is counterbore, or the upper limit for the counterbore depth when the hole type is counterbore A counterbore part depth Max 808, a color arrangement 809 for storing color information when coloring the model file, and the like.

  That is, the coloring tool colors the color indicated by 809 for the hole created by the hole feature that meets the conditions of 802 to 808. The above is the description of FIG.

  Returning to the description of FIG. In step S402, the coloring tool displays the main dialog 900 of FIG. 9 on the display screen (step S402). The main dialog 900 is a screen for selecting which of “automatic coloring”, “coloring”, “decoloring”, “setting”, and “ending” is to be executed.

  The coloring tool determines whether or not the pressing of the “setting” button 901 has been received (step S403). When the pressing of the “set” button 901 is accepted, the process proceeds to step S411, and the color arrangement table update process is performed. Details of the color arrangement table update processing will be described later with reference to FIG. If pressing of the “set” button 901 is not accepted, the process proceeds to step S404.

  In step S404, the coloring tool determines whether or not the “coloring” button 902 has been pressed (step S404). When the pressing of the “coloring” button 902 is accepted, the process proceeds to step S412 to perform batch coloring processing. Details of the batch coloring process will be described later with reference to FIG. If the pressing of the “coloring” button 902 is not accepted, the process proceeds to step S405.

  In step S405, the coloring tool determines whether or not the “decoloring” button 603 has been pressed (step S405). If the pressing of the “decoloring” button 603 is accepted, the process proceeds to step S613 to perform the decoloring process. Details of the decoloring process will be described later with reference to FIG. If the pressing of the “color removal” button 603 is not accepted, the process proceeds to step S406.

  In step S406, the coloring tool determines whether a hole feature to be newly added to the model file is added by the operator (user) operating the CAD software (step S406 / detection). Specifically, event information indicating that a feature has been added (created) to a model file is acquired by using an API of CAD software, an internal ID of the added feature is acquired from the event information, and a feature type is acquired. Specifically, it is determined whether or not the added feature type is a hole by acquiring CAD software-specific feature types (shown in FIG. 19) such as extrusion, extrusion cut, fillet, and hole. As a result of the determination, if the feature type is a hole, the process proceeds to step S407 on the assumption that a hole feature has been created. If the feature type is not a hole, the process proceeds to step S410.

  In step S407, the coloring tool obtains configuration information (parameters / illustrated in FIG. 19) for the feature specified in step S406 by using the CAD software API (requests the configuration information of the feature from the CAD software, The configuration information is acquired by receiving the response of the configuration information from the CAD software / step S407), and the process proceeds to step S408.

  Specific examples of configuration information include, for example, hole type (information regarding the type of hole such as a hole or countersink), hole diameter (through hole diameter), counterbore diameter (counterbore diameter specific to the counterbore hole), counterbore depth, etc. (Counterbore depth specific to the counterbore).

  Note that there are parameters that cannot be acquired because the parameter of the feature is different if the hole type is different. Specifically, the through hole diameter is a parameter common to the hole and the countersink, but the counterbore diameter and the counterbore depth are not included in the hole parameters.

  The coloring tool collates the parameter acquired in step S407 with 802 to 808 of the color arrangement table 800 stored in the external memory at the time of step S407, and determines whether there is a corresponding record (step S408). When there is no corresponding record (when the created hole feature does not meet the condition of the color scheme table / when the created hole feature does not satisfy the condition of the color scheme table), the process returns to step S402. If there is a corresponding record (when the created hole feature matches the condition of the color arrangement table / when the created hole feature satisfies the condition of the color arrangement table), the process proceeds to step S409.

  Here, specific contents of the collation process using the color arrangement table 800 will be described.

  For the collation, the feature parameter acquired in step S407 and the color arrangement table 800 are used. The collation order is ascending from record number 1 of the color arrangement table.

  First, matching is performed using the value of the hole type 802, and if they match, the through hole diameter Min803 and the through hole diameter Max804, the counterbore diameter Min805 and the counterbore diameter Max806, and the counterbore depth Min807 and the seat are matched. By using the drilling depth Max 808, it is verified from the acquired feature parameter whether the created hole feature satisfies the record condition (matches the condition).

  Specifically, when the hole type 802 matches with “hole”, a matching range of the through hole diameter is set using the values of the through hole diameter Min 803 and the through hole diameter Max 804, and the through hole diameter of the feature parameter is the matching range. If it matches (contains), it is considered as a match, and if it does not match, it is considered as a mismatch. When the hole type is “hole”, the counterbore hole diameter and the counterbore depth are not included in the collation items, so the collation match (satisfies) is determined in the record, and the color information stored in the color scheme 809 And the process proceeds to step S409.

  If the coloring tool considers that the record does not match, the coloring tool obtains the record of the next record No and performs the same matching process. If the matching record is not determined even after reaching the final record, the process proceeds to step S402. Migrate to When the hole type is a counterbore, in addition to the through-hole diameter, the counterbore diameter and the counterbore depth are sequentially checked, and if all match, the record is determined to match.

  In step S409, the coloring tool determines whether the automatic coloring 904 check in FIG. 9 is on. If the check is on, the coloring tool uses the API of the CAD software for the hole feature hole received in step S406. In step S408, the color information acquired from the corresponding record in the color arrangement table 800 is colored (step S409 / feature color change processing is performed). The automatic coloring 904 is a manual setting for collectively changing the hole color according to a manual operation of the user (pressing reception of the “coloring” button 902), and a hole of a feature added / created by creating / adding a feature in CAD software. This is a check box for switching and setting the automatic setting for performing the process of automatically changing the color. It is assumed that setting information on whether manual setting or automatic setting is performed is managed in a setting management table (not shown) (stored in the external memory of the PC 100). The state of the coloring process is shown in FIG.

  Specifically, the coloring process is performed only on the surface (hole created by the hole feature) constituting the hole feature. In general, CAD software manages model file plane information in the order of priority (1) “plane”> (2) “feature”> (3) “entire model”. The coloring tool uses the CAD software API to specify (2) “feature” as a coloring target, and instruct the CAD software to color the hole feature that matches the condition with the color that matches the condition in step S408. . Then, the CAD software that has received the instruction performs coloring (coloring) indicated by the color information designated by the coloring tool for the feature. An example of the state of the feature before and after coloring is shown in FIG. In FIG. 19, the feature configuration information is limited to the hole feature configuration information. In addition, description of configuration information of features after coloring is omitted.

  If the check of automatic coloring 904 is OFF, the process proceeds to step 410 without coloring.

  FIG. 11 shows the record contents of the color arrangement table 800 and how holes are colored in the model file as an example of the processing results of steps S406 to S409.

  In step S410, the coloring tool determines whether or not the “end” button 605 has been pressed (step S410). If it is determined that the “end” button 605 has not been pressed, the process returns to step S402, and “end”. If it is determined that the button 605 has been pressed, the information of the color arrangement table 800 is stored in the external data, the command end process is executed, and the coloring tool is ended. The above is the description of FIG.

  Next, the details of the color arrangement table update process in the embodiment of the present invention will be described with reference to FIG. The color arrangement table update process is, for example, the process of step S411 in FIG.

  The coloring tool generates a screen of a setting dialog for setting a color scheme, and generates and displays a screen in which the information of the color scheme table 800 shown in FIG. 8 is inserted into the setting grid 1001 (list display) in ascending order of No801. (Step S501).

  Specifically, the property values of the color arrangement table header corresponding to the header of the setting grid 1001 are displayed on the setting grid 1001 in ascending order from the record having the record No. 801 of 1. The through hole diameter Min 803 and the through hole diameter Max 804 display the property value of the through hole diameter Min 803 on the left side of the grid provided in the through hole diameter of the setting grid 1001 and the property value of the through hole diameter Max 804 on the right side, respectively. For the counterbore diameter Min805 and the counterbore hole diameter Max806, and the counterbore depth for the counterbore depth Min807 and the counterbore depth Max808.

  When the hole type is “hole”, negative values are stored in counterbore diameter Min805, counterbore diameter Max806, counterbore depth Min807, and counterbore depth Max808 of the color arrangement table. The value is not displayed in the corresponding grid. In addition, the item in which the negative value is stored is a collation between the hole feature and the color arrangement table in step S408 in FIG. 4 and step S604 in FIG. Is not used in the determination process of whether the condition of the color arrangement table is satisfied.

  Also, the display of hole types 1002 to 1009 shown in FIG. 10 is updated by accepting an operation for selecting an arbitrary record on the grid (for example, a mouse click operation on a record to be selected). Specifically, for example, as shown by 1020 in FIG. 10, the hole type 802 of the record currently selected to the hole type 1002, the through hole diameter Min 803 of the record currently selected to the through hole diameter 1003, and the through hole diameter 1004 are currently selected. Through hole diameter Max 804 and counterbore hole diameter 1005 of the record selected for the record, counterbore hole diameter Max 806 and counterbore depth 1007 of the record currently selected to the counterbore diameter 1006 The counterbore depth Max 808 of the record currently selected to the counterbore depth Min807 and the counterbore depth 1008 is displayed.

  In step S502, the coloring tool determines whether input of parameters 1002 to 1009 of the setting dialog 1000 by a user operation has been received (step S502). If it is determined that parameter input has been received, the input value is reflected in the items 1002 to 1009 according to the input operation (display / step S511).

  The hole type 1002 to the counterbore depth 1008 accepts a direct input, and the color 1009 accepts a press of a color designation button 1010, thereby allowing a color selection dialog (not shown) to select a color to be adopted from a plurality of predetermined colors. The color selection / designation is received in the color selection dialog, and the selected color is displayed in the color 1009.

  If it is determined in step S502 that no parameter input has been received, the coloring tool determines whether an operation (instruction) for adding a record to the color arrangement table has been received (step S503). Specifically, it is determined whether or not the “Add” button 1011 shown in FIG. 10 has been pressed. When the “Add” button 1011 is pressed, the values displayed in the hole type 1002 to the color 1009 are set to the setting grid 1001. Is added as a new record at the end of, and at the end of the color arrangement table 800 (step S507). FIG. 11 shows how the setting dialog and the color arrangement table record are added.

  If the pressing of the “add” button 1011 is not accepted, the coloring tool determines whether an operation (change instruction) for changing the value of the record being selected has been accepted (step S504). Specifically, when pressing of the “update” button 1012 shown in FIG. 10 is received, it is determined that a change instruction has been received. When the “update” button 1012 is pressed, the values displayed in the hole type 1002 to the color 1009 when the press is received are reflected in the property of the record selected in the setting grid 1001 and the corresponding record in the color arrangement table 800. Then, the process of updating the color arrangement table 800 is performed (step S508). Specifically, the same property value as that in step S504 is stored for the record in the color arrangement table 800 corresponding to the record No reflected in the setting grid 1001, and the process proceeds to step S502. FIG. 12 shows how the record of the setting dialog and the color arrangement table is changed.

  If it is determined in step S504 that an operation (change instruction) for changing the value of the selected record has not been received, the coloring tool determines whether an operation for changing the order of records in the color arrangement table (order change instruction) has been received. (Step S505).

  Specifically, in the setting dialog 1000 shown in FIG. 10, an operation for changing the display order in which the record dragged by the drag-and-drop operation on the setting grid 1001 row is moved (dropped) before or after another record. Is received, the display order of the operation reception target records is reflected and displayed on the setting grid 1001, and the order of the records in the color arrangement table 800 is changed based on the reflected information (step S509). FIG. 13 shows how the record order of the setting dialog and the color arrangement table is changed.

  That is, the order of the record numbers reflected on the setting grid 1001 is reflected on the records of the color arrangement table 800 (the order is changed so that the order becomes the same order).

  If the coloring tool has not received an operation for changing the order of the records in the color arrangement table (order change instruction), the coloring tool determines whether an operation for deleting the record in the color arrangement table (deletion instruction) has been received (step S506). When the pressing of the delete button 1013 shown in FIG. 10 is accepted, it is determined that the delete instruction has been accepted. When an operation for deleting a record in the color arrangement table is accepted, the record currently selected in the setting grid 1001 is deleted from the setting grid 1001, and the record on the color arrangement table 800 corresponding to the record No. of the record deleted from the setting grid 1001 is changed to the color arrangement. A process of deleting from the table 800 is performed (step S510). FIG. 14 shows how the record of the setting dialog and the color arrangement table is deleted. The above is the description of FIG.

  Next, with reference to FIG. 6, the details of the collective coloring process in the embodiment of the present invention will be described. The batch coloring process is, for example, the process of step S412 in FIG.

  The coloring tool acquires the first internal IDs of a plurality of feature information constituting the model file using the API of the CAD software (step S601). Specifically, the coloring tool requests the CAD software for the top-level feature (a feature including at least feature type information) in the list of feature information managed by the CAD software, and the CAD software issues the request. Receiving and responding / transmitting the requested feature type to the coloring tool, and the coloring tool obtains the type information.

  The coloring tool determines whether or not the feature type is a hole using the method described above in step S406 of FIG. 4 with reference to the feature type acquired in step S601 (step S602). If the feature type is a hole, the process proceeds to step S603. If the feature type is not a hole, the process proceeds to step S606.

  In step S603, the coloring tool acquires the parameter (configuration information) of the hole feature determined to be the hole in step S602 using the method described in step S407 of FIG. 4 (step S603). The process proceeds to step S604.

  In step S604, the coloring tool refers to the parameter acquired in step S602, and whether there is a record in the color arrangement table 800 corresponding to the hole feature parameter acquired in step S601 (whether the acquired hole matches the condition of the color arrangement table). Whether the acquired hole satisfies the condition of the color arrangement table is determined using the method described above in step S408 of FIG. 4 (step S604). If there is a record of the corresponding color arrangement table 800, a process of coloring the color of the color arrangement 809 of the color arrangement table 800 determined to be applicable to the hole of the hole feature acquired in step S601 is performed (step S605). The coloring process is as described above, for example, in the description of step S409 in FIG.

  If there is no record in the color arrangement table 800 corresponding to the hole feature parameter acquired in step S601, the coloring tool shifts the processing to step S606.

  In step S606, the coloring tool uses the CAD software API to determine whether the feature being processed is the final feature of the features constituting the model file (step S606). Specifically, for example, the CAD software is inquired about the existence of the next feature, and the CAD software answers the existence of the next feature. The coloring tool accepts the answer and determines that the feature being processed is not the final feature if the next feature is present, and determines that the feature being processed is the final feature if the next feature is not present .

  If the next feature exists, the coloring tool requests the configuration information of the next feature from the CAD software, the CAD software returns the configuration information of the next feature to the coloring tool, and the coloring tool performs the configuration. Information is acquired (step S607), and the process proceeds to step S602. If the next feature does not exist, the process ends. The state of the batch coloring process is shown in FIG. The above is the description of FIG.

  Next, the details of the decoloring process in the embodiment of the present invention will be described with reference to FIG. The decoloring process is, for example, the process of step S413 in FIG.

  The processing in steps S701 to S704 and step S706 is the same as the processing in steps S601 to S604 and step S606 in FIG. 6, respectively, and thus detailed description thereof is omitted here. In addition, the transfer destination of the process according to the determination result in each determination step is as shown in FIG. In step S704 in FIG. 7, information on the color scheme 809 of the color scheme table 800 is not acquired in determining whether the hole feature using the color scheme table 800 matches the conditions of the color scheme table.

  If it is determined in step S704 that the hole feature acquired in step S701 matches the condition of the color arrangement table 800, the coloring tool performs a decoloring process for decoloring the color of the hole created by the hole feature that matches the condition. (Step S705), the process proceeds to step S706.

  Specifically, the color information deletion process is performed only on the surface constituting the hole feature using the API of CAD software. For example, the coloring tool transmits an instruction to delete the color information of the hole feature of the hole to be decolored to the CAD software, and the CAD software receives the instruction to delete the color information, and the color corresponding to the target hole feature Delete information.

  The model files managed by the CAD software are managed in the priority order of (1) “face”> (2) “feature”> (3) “whole model”. (2) Since the color information set for the hole feature disappears by deleting the color information of “feature” (hole feature), (3) the hole feature is determined by the color information set for “whole model”. The color of the hole will be displayed. The above is the description of FIG. The state of the decoloring process is shown in FIGS.

  As described above, according to the present invention, it is possible to provide a mechanism that can efficiently change the color of an object created by a feature.

  For example, the holes of the hole features on the CAD software can be automatically colored and decolored based on the information in the color table, which contributes to labor saving of coloring work by the user and prevention of erroneous coloring due to coloring omission and erroneous operation. can do.

  <Second Embodiment>

  Next, with reference to FIG. 20, the flow of processing in the second embodiment of the present invention will be described. In the description of the second embodiment, descriptions of processes, screens, and data configurations common to the first embodiment among the processes, screens, and data configurations of FIGS. 1 to 19 are omitted.

  The second embodiment provides a mechanism that can efficiently change the color of an object created by a feature when a CAD file is saved.

  For example, after executing the process of coloring the hole feature in response to pressing of the “coloring” button 902, the color scheme of the record (rule) of the color scheme table used for the coloring is changed, and the “automatic coloring” 904 is checked later. When a hole (hole feature) matching the rule of the record is generated, different colors are colored for a plurality of holes of the same type (for example, the same standard).

  When a CAD file is passed to another person (for example, a user who develops and browses a CAD file using CAM software) in a state in which different colors are colored even though the holes are of the same type, the colored color is changed. Based on this, there is a possibility of being mistaken for a different type of hole even though it is the same type of hole.

  Therefore, in the second embodiment, when saving a CAD file, it is checked whether there is a hole colored in a different color with the same type of hole, and the user is notified.

  Specifically, the coloring tool monitors file saving processing of the CAD software and determines whether a file saving operation (saving instruction) has been performed in the CAD software (step S2001 / corresponding to saving instruction detecting means). For example, when pressing of the “overwrite save” button is accepted, it is determined that a file save operation has been performed, and the process proceeds to step S2002. If the file saving operation is not performed, the process ends.

  The coloring tool determines ON / OFF of the automatic coloring function described in the first embodiment (step S2002). If the automatic coloring function is OFF (if automatic coloring 904 in FIG. 9 is not checked), the process is terminated. If the automatic coloring function is ON (if automatic coloring 904 in FIG. 9 is checked), the process proceeds to step S601.

  The processing in steps S601 to S607 shown in FIG. 20 is the same as the processing in steps S601 to S607 in FIG.

  If the coloring tool determines in step S604 that the hole of the acquired hole feature satisfies the condition of the color arrangement table, the coloring tool moves the process to step S2003.

  In step S2003, the coloring tool requests the CAD software for a feature as shown in FIG. 19, obtains a response from the CAD software, and obtains the feature acquired in step S601 based on the feature information / feature configuration information. It is determined whether there is a hole feature having the same type, diameter, and depth (the same type of hole) as the hole of the inside feature and a different color scheme (corresponding to step S2003 / color determination means). That is, it is determined whether there is a hole feature having a different color scheme value among holes of other hole features that match the conditions of the color scheme table having a condition that the holes of the hole feature being processed match.

  If there is a hole feature with the same type of hole and a different color scheme, the identification information (ID) of the hole feature being processed is stored in the memory as “a hole with the same type of hole colored in different colors” (Step S2004). If there is no hole feature with a different color scheme for the same type of hole, the process proceeds to step S606.

  When the coloring tool determines in step S606 that the feature being processed is the final feature, the coloring tool notifies the user of the “holes in which different colors are colored with the same type of holes” stored in step S2004 ( Step S2005). Specifically, as shown in FIG. 21, a notification screen in which identification information (here, hole standards) of holes of the same type that are colored in a plurality of different colors is inserted and displayed on the display screen To do.

  Then, the coloring tool determines whether an instruction to unify a plurality of different colors colored in the same type of hole into one color has been received (step S2006). When the “Cancel” button in FIG. 21 is pressed, it is determined that no unification instruction has been given, and the coloring tool instructs the CAD software to cancel the storage, and cancels the file storage. In addition, if pressing of the “Save” button is accepted in a state where all the check boxes in FIG. 21 are not checked, it is determined that the unification instruction has not been given, and the file is left as it is without unifying the colors. In order to save the file, the coloring tool instructs the CAD software to execute the file saving process, and the CAD software saves the file.

  When the “Save” button is pressed while the check box of FIG. 21 is checked, the coloring process of FIG. 6 is executed for the type of hole (hole feature) whose check box is checked. (Step S2007) to save the file.

  In the description of FIG. 6 described above, the processing of steps S602 to S606 has been executed for all the hole features. In step S2007, what is acquired in step S601 is checked in FIG. 21 when the “Save” button is pressed. This is the first feature of the standard hole feature whose box is checked. The next feature acquired in step S607 is a standard hole feature whose check box is checked in FIG. 21 when the next “Save” button is pressed. In step S607, it is determined whether the last feature is a standard hole feature whose check box is checked in FIG. 21 when the “Save” button is pressed.

  When there are a plurality of standards whose checkboxes are checked, the coloring tool executes the processing of step S2007 for the hole feature of each standard, and updates the hole color of the hole feature to the latest color arrangement table color scheme. Thereafter, the CAD software is instructed to save the CAD file whose color scheme has been updated, and the CAD software accepts the instruction and executes the saving of the CAD file, and the process ends. The above is the description of FIG.

  As described above, according to the second embodiment, it is possible to provide a mechanism that can efficiently change the color of an object created by a feature when a CAD file is stored.

  Further, when saving a CAD file, it is possible to check whether there are holes of the same type that are colored in different colors and notify the user.

  Further, notification can be made when the user does not intend and the same type of feature is colored differently.

  Specifically, when the automatic coloring function is ON, it is possible to notify the user of the presence of a hole in which a different color is colored with the same type of hole.

Note that the CPU 201 of the PC 100 transmits a CAD file colored with coloring roots and saved by CAD software to the PC 110 in response to a user operation. Further, the CPU 201 of the PC 110 receives the CAD file and stores it in the external memory, expands the CAD file using the function of the CAM software, and displays it on the display screen. At this time, the CAM software reads the color information (color arrangement) of the feature of the CAD file and defines it by the feature.
The color is displayed on the surface to be expressed (for example, the surface inside the hole).

  As described above, according to the present invention, it is possible to provide a mechanism that can efficiently change the color of an object created by a feature.

  In the description of the embodiment of the present invention, the coloring tool operates to instruct the CAD software to color a feature (a surface managed in units of features (for example, the inner surface of a hole)). . Thereby, the processing load can be reduced and the processing time can be reduced by coloring the diameter, depth, and shape of each hole set in the model one by one with the rule.

  Also, depending on the model, it seems that there are multiple holes with the same diameter and depth, but some holes are “holes” for fitting parts, and some holes are simple “cavities” as model designs. Sometimes. In other words, it may be a hole with a similar shape but a different character. If a hole is struck and colored simply under the conditions of diameter and depth, the same color is colored in the holes having different characteristics as described above. Therefore, there is a problem that a user of the CAM software who is not a creator of the model, for example, receives and refers to the CAD file of the model, for example, mistakes that the holes of different characteristics are the same hole. When a user creates a hole using a feature, there are many cases where an explicit “hole” for fitting a part is explicitly created. Therefore, in the present invention, the inner surface of the hole defined by the feature is colored for the feature, and the cavity (hole) shaped like a hole that is not managed by the feature is not colored. It makes it possible to distinguish holes with different personalities.

  It should be noted that the present invention can be implemented as, for example, a system, apparatus, method, program, or storage medium, and can be applied to a system composed of a plurality of devices. You may apply to the apparatus which consists of one apparatus.

  Specifically, the PC 100 and the PC 110 are integrated, and CAD software, CAM software, and a coloring tool are stored in the same PC, and each processing of the above-described embodiment (for example, processing of each functional unit described in FIG. The processing of each step described with reference to FIGS. 4 to 21 may be executed.

  Further, the CAD file is stored in the PC 100 and PC 110, but the CAD file may be stored in a predetermined storage area such as a server device different from the PC 100 and PC 110, for example. In this case, for example, the PC 100 accesses the server device and expands the CAD file by using the functions of the CAD software and the coloring tool installed in the server device, and generates information on each screen of FIGS. Then, the PC 100 displays the screen by transmitting to the PC 100, and transmits the contents of the operation instruction received by the PC 100 to the server device, so that the server device executes the processing of each step of FIGS. May be. In addition, the CAM software is installed in the server device, and the PC 110 remotely activates and operates the CAD software of the server device, thereby performing development of the CAD file, reading of the feature color of the CAD file, and display processing. You may do it. That is, the present invention may be realized as an information processing system using a plurality of devices.

  In the description of the embodiment described above, in FIG. 19, color arrangement information is stored in association with the feature itself. For example, a hole surface generated and defined by the feature (corresponding to the feature in the CAD file) It is conceivable to store the color arrangement information in association with the surface that is linked under the stored feature. Therefore, when executing the coloring process in step S409 in FIG. 4, step S605 in FIG. 6, and step S2007 in FIG. 20, the coloring tool inquires the CAD software for information on the surface to be linked under the feature to be colored, The CAD software is instructed to color the color scheme (color) of the rule of the color scheme table that matches the feature with the coloring tool, and the CAD software accepts the instruction and colors the surface to be colored. You may make it color the color instruct | indicated from the tool.
