Description

The present invention easily specifies the closest distance between the part data operating in the range of motion of the part data having a movable part and the part data different from the part data, which operates in the range of motion according to the instruction from the user. It relates to an information processing device that can be used, a control method thereof, and a program.

Conventionally, there is a CAD (Computer Aided Design) application for designing a product or the like using an information processing device such as a personal computer. CAD applications are classified into two types: a two-dimensional CAD application that designs with a conventional two-dimensional drawing such as a front view, a plan view, and a side view, and a three-dimensional CAD application that designs with a three-dimensional model.

In particular, the part data that composes the product designed by the 3D CAD application may have a moving part, and in the design, the part having the moving part is used to confirm whether or not the moving part operates normally. Interference between the data and other component data must be confirmed. In the three-dimensional CAD application, the user can operate the component data according to the movable portion by simply dragging the component data including the movable portion. In other words, the operating status of the part data according to the moving parts, which was difficult to reproduce in the 2D drawing expressed by the 2D CAD application, can be easily reproduced in the 3D CAD application. We visually check whether they interfere with each other.

Patent Document 1 below discloses a mechanism for geometrically detecting interference by moving a parent component at a predetermined movement pitch with respect to component data including such a movable portion.

JP 2000-11302

By the way, when designing a product, it is also examined whether or not the necessary distance (space) can be secured between the component data. A product is made by manufacturing a part from part data and assembling the manufactured part, but a space for a worker to move a hand or a tool is required when performing this assembly. Without this space, a design designed by a 3D CAD application would be a desk theory. In addition, a certain amount of space is required between the component data provided with the movable portion described above and other component data. This is because even if the component data including the moving part and the other component data do not interfere with each other at the design stage, they may interfere with each other depending on the size error of the manufactured component.

In order to verify whether the required space can be secured between such component data, the 3D CAD application has a function of measuring the shortest distance between the specified component data. The designer uses this function to measure the shortest distance between component data and confirm whether the required space can be secured.

However, with the functions provided in general 3D CAD applications, only the shortest distance between parts in a temporary operating state when operating parts data with moving parts can be measured, so it is within a certain movable range. In order to obtain the distance (closest distance) when the part data is closest to the other part data, the measurement must be repeated. Therefore, in order to efficiently measure the closest approach distance, a skilled designer predicts the location requiring measurement with high accuracy based on experience and intuition, and reduces the number of measurements as much as possible.

However, when an inexperienced designer performs the same method, the prediction accuracy is not high, so the number of measurements tends to increase, and it cannot be said that the efficiency is good. If the number of measurements is reduced without the prediction accuracy being high, the design quality may deteriorate. Therefore, it is not always sufficient to reduce the number of measurements easily.

Further, as a conventional technique, there is a method of calculating the distance when the component data including the movable portion is closest to the other component data by simulation in the range of motion in which the component data operates. By using this, it is possible to easily specify the closest distance, but this mechanism cannot be used at the design stage where the formal range of motion has not been determined. That is, when searching for a range of motion in which the required space can be secured from the current range of motion, there is no choice but to repeatedly measure the shortest distance between parts in a temporary operating state as described above. To the last, this simulation mechanism is a confirmation work performed when the design is almost completed, and cannot be used at the design stage, so there is a problem that the design cannot be performed efficiently.

Therefore, an object of the present invention is a distance at which the part data operating in the range of motion of the part data having a movable portion and operating in the range of motion according to an instruction from the user and the part data different from the part data are closest to each other. Is to provide a mechanism for easily identifying.

In order to achieve the above object, the information processing device of the present invention is a component data having a movable portion, and is an information processing device that operates the component data composed of a three-dimensional model according to the movable portion. By operating the component data in the movable range according to the instruction from the user in the movable range of the component data, it is controlled to measure the shortest distance between the component data and the component data different from the component data. Among the measurement control means, the distance acquisition means for acquiring the shortest distance measured by the measurement control means, and the plurality of shortest distances acquired by the distance acquisition means, the component data whose component data is different from the component data It is characterized by including the closest approach distance specifying means for specifying the closest approach distance.

According to the present invention, it is easy to make the closest distance between the part data operating in the range of motion of the part data having a movable part and the part data different from the part data. Since it can be specified to, it has the effect of reducing the labor of the worker without relying on the experience and intuition of the worker.

Further, the definition file and various information tables used by the program according to the present invention are stored in the external memory 211.

Next, a functional configuration diagram showing the functional configuration of the information processing device 101 will be described with reference to FIG. It should be noted that the functional configuration of FIG. 3 is an example, and it goes without saying that there are various configuration examples depending on the application and purpose.

The information processing device 101 includes a storage unit 301 and a display control unit 302. The storage unit 301 corresponds to the RAM 203 and the external memory 211, and stores various data handled by the information processing device 101. In this embodiment, in particular, a 3D model to be displayed by a 3D CAD application, a 2D drawing, and various tables described later are stored.

The display control unit 302 is a control unit for displaying various data stored in the storage unit 301 on the display 210. Various data are displayed on the display 210 in response to instructions from the three-dimensional model control unit 311 and the screen display control unit 321 described later.

Further, as described above, the information processing apparatus 101 has the three-dimensional CAD application 310 and the shortest distance measurement program 320 installed. The 3D CAD application 310 includes a 3D model control unit 311, a shortest distance acquisition unit 312, a mode switching unit 313, a distance measurement unit 314, an operating state acquisition unit 315, a shortest distance identification display control unit 316, and a closest state reproduction control unit. It is equipped with 317. These are provided in the 3D CAD application 310 as APIs.

The 3D model control unit 311 reads the 3D model stored in the storage unit 301 into the RAM 203, and creates, edits, deletes, etc. the 3D model according to the function of the 3D CAD application 310 instructed by the user. Execute. In addition, it is composed of a three-dimensional model and has a function of operating component data including a movable part in response to an instruction from a user.

When the shortest distance acquisition unit 312 receives an instruction from the shortest distance acquisition instruction unit 324, which will be described later, the shortest distance acquisition unit 312 is operating the component data including the movable portion (hereinafter, the first component data) by the three-dimensional model control unit 311. , Instruct the mode switching unit 313 to enter a mode in which the distance measuring unit 314 continues to measure the shortest distance between the component data and other component data (hereinafter, the second component data) at regular intervals. put out. Then, the shortest distance acquired by measuring with the distance measuring unit 314 is passed to the shortest distance acquisition instruction unit 324. In addition, the operating state of the first component data acquired by the operating state acquisition unit 315 is also acquired and passed to the shortest distance acquisition instruction unit 324.

The mode switching unit 313 switches the mode of the three-dimensional CAD application 310. In the present embodiment, a mode in which the distance measuring unit 314 measures the shortest distance (shortest distance measuring mode) and a mode in which the distance measuring unit 314 does not measure the shortest distance by operating the first component data under the control of the three-dimensional model control unit 311. There are two (normal mode). If the distance measuring unit 314 constantly measures the shortest distance by operating the first component data according to the movable unit, the load on the information processing device 101 becomes high. That is, there is a problem that the user's design work is hindered. Therefore, the mode switching unit 313 solves such a problem by switching to the mode in which the distance measuring unit 314 measures the distance only when necessary.

The distance measuring unit 314 measures the shortest distance between component data. In the present embodiment, the first component data is operated in a certain state while the three-dimensional model control unit 311 is operating within the range of motion instructed by the user according to the movable unit. The shortest distance between the part data and the second part data is continuously measured. Since the method for measuring the shortest distance is a conventional technique, the description thereof will be omitted. Conventionally, in a three-dimensional CAD application, since there is a function of measuring the shortest distance between two component data, the same measurement as this is performed.

The operating state acquisition unit 315 acquires the operating state of the first component data at the time when the shortest distance is measured by the distance measuring unit 314, and passes it to the shortest distance acquiring unit 312. The operating state is used by the closest state reproduction control unit 317, which will be described later.

When the shortest distance identification display control unit 316 receives an instruction from the shortest distance identification display instruction unit 326, which will be described later, the shortest distance identification display control unit 316 receives the first component data and the second component data according to the fact that the shortest distance is measured by the distance measurement unit 314. The shortest distance is identified and displayed from the part data of. That is, which part of the first part data and which part of the second part data the straight line connecting with which part is the shortest distance cannot be determined only by the value of the shortest distance measured by the distance measuring unit 314. Therefore, the straight line corresponding to the shortest distance is identified and displayed in real time each time the shortest distance is measured to help the user's understanding.

When the closest approach state reproduction control unit 317 receives an instruction from the closest approach state reproduction instruction unit 327, which will be described later, to reproduce the operation state acquired by the operation state acquisition unit 315, the closest approach state reproduction control unit 317 instructs the operation state of the first component data. Operate so that the operating state is as set.

Further, the shortest distance measurement program 320 includes a screen display control unit 321, an input reception unit 322, a CSV output unit 323, a shortest distance acquisition instruction unit 324, a closest distance determination unit 325, a shortest distance identification display instruction unit 326, and a closest state. A reproduction instruction unit 327 is provided.

The screen display control unit 321 controls the display of various screens for receiving operations from the user. For example, the shortest distance measurement screen 500 (see FIG. 5), which will be described later. Further, the result executed by the shortest distance measurement program 320 is displayed on the shortest distance measurement screen 500.

The input receiving unit 322 receives character input and button pressing from the user through the input device 209.

The CSV output unit 323 outputs a list of the shortest distances acquired by instructing the shortest distance acquisition instruction unit 324 as a CSV (Comma-Separated Values) format file. In this embodiment, the CSV format is used, but the file format is not particularly limited as long as a list of the shortest distances can be output.

The shortest distance acquisition instruction unit 324 causes the shortest distance acquisition unit 312 to operate the first component data in the range of motion instructed by the user in the range of motion of the component data, and causes the first component data and the second component data to operate. Instruct to measure the shortest distance to the part data of. Then, the shortest distance passed from the shortest distance acquisition unit 312 is received at any time. In addition, an instruction is given to the operating state acquisition unit 315 to acquire the operating state of the first component data when the shortest distance is measured, and the operating state is received from the operating state acquisition unit 315.

The closest distance determination unit 325 is instructed by the user of the first part data that the shortest distance acquired by instructing the shortest distance acquisition instruction unit 324 is the first part data and the second part data. Determine if it is the closest distance in the range of motion. In the shortest distance acquisition instruction unit 324, the shortest distance can be acquired at any time while the first component data is being operated by the three-dimensional model control unit 311. Therefore, the distance with the smallest value among the plurality of acquired shortest distances is obtained. The shortest distance with is determined to be the closest distance. That is, when the three-dimensional model control unit 311 operates the movable unit of the first component data, it is desirable to operate the movable unit so as to cover the range of motion instructed by the user.

The shortest distance identification display instruction unit 326 issues an instruction to the shortest distance identification display control unit 316 to identify and display the shortest distance acquired by the shortest distance acquisition instruction unit. As described above, it is desirable to perform the identification display of the shortest distance in real time according to the operation by the three-dimensional model control unit 311.

The closest approach state reproduction instruction unit 327 specifies the operating state when the shortest distance determined to be the closest distance by the closest distance determination unit 325 is measured from the information acquired by the shortest distance acquisition instruction unit 324, and the closest approach state. An instruction is given to the reproduction control unit 317 to reproduce the operating state.

Next, a series of processes performed by the information processing apparatus 101 according to the embodiment of the present invention will be described with reference to the flowchart shown in FIG.

When performing the process shown in FIG. 4, the CPU 201 of the information processing device 101 is in a state in which the three-dimensional CAD application 310 is activated in response to an instruction from the user and the three-dimensional model can be operated. This will be described below.

In step S401, the CPU 201 of the information processing device 101 activates the shortest distance measurement program 320 in response to an instruction from the user through the input device 209.

In step S402, when the CPU 201 of the information processing apparatus 101 confirms the activation of the shortest distance measurement program 320 in step S401, it determines whether or not the three-dimensional CAD application 310 satisfies the start condition of the shortest distance measurement program 320. More specifically, make sure that the currently active document is assembly data, that there is only one active document open, and that the current active document has been saved. If all of the above are satisfied, it is determined that the start condition is satisfied. These prevent unexpected behavior of the 3D CAD application 310 and unexpected acquisition of data. The assembly data is data that can be handled by a three-dimensional CAD application, and includes reference information of one or more component data or assembly data. That is, it manages information such as the absolute path where the part data and the assembly data are stored and the position where the part data is placed. If it is determined that the start condition of the shortest distance measurement program 320 is satisfied, the process proceeds to step S403. If it is determined that the start condition of the shortest distance measurement program 320 is not satisfied, an error message is displayed and the series of processes is terminated.

In step S403, the CPU 201 of the information processing device 101 uses the screen display control unit 321 to display the shortest distance measurement screen 500 as shown in FIG. 5 on the display 210.

In step S404, the CPU 201 of the information processing apparatus 101 uses the input receiving unit 322 to receive selection of two component data to be measured at the shortest distance. In particular, among the component data included in the assembly data opened by the three-dimensional CAD application 310, at least one selection of component data including a moving portion is accepted. More specifically, when the user selects the text box 501 of the shortest distance measurement screen 500 and then selects the component data to be measured, the screen display control unit 321 is selected from the three-dimensional CAD application 310. The part name of the part data is acquired and displayed in the text box 501. At the same time, the acquired part name is registered in the measurement target part name a701 of the measurement target part table 700 shown in FIG. 7. Similarly, for the other part data, the selection of the part data is accepted after the selection of the text box 502, the part name of the part data is displayed in the text box 502, and the part name is the measurement target of the measurement target part table 700. Register in the part name b702.

The measurement target component table 700 (see FIG. 7) is a table stored in the storage unit 301 of the information processing apparatus 101. The measurement target component table 700 is composed of the measurement target component name a701 and the measurement target component name b702. As described above, the measurement target component name a701 and the measurement target component name b702 store the component names of the measurement target component data whose selection has been accepted in step S404.

Hereinafter, in the present embodiment, description will be given using the first component data 601 and the second component data 602 shown in FIG. The first component data is component data including a moving portion. The first component data is rotated about the vertical axis passing through the center point of the first component data as a rotation axis. The second component data is component data that does not have a moving portion. When each is selected in step S404, the part name of the first part data 601 is displayed in the text box 501, and this part name is registered in the measurement target part name a701. Further, the part name of the second part data 602 is displayed in the text box 502, and this part name is registered in the measurement target part name b702.

In step S405, the CPU 201 of the information processing device 101 accepts the press of the control button 503 indicating "measurement start" on the shortest distance measurement screen 500.

Then, in step S406, the CPU 201 of the information processing apparatus 101 uses the input receiving unit 322 to determine whether or not the component data to be measured is selected. Whether or not the component data to be measured is selected is determined by whether or not the component names are registered in the measurement target component name a701 and the measurement target component name b702 in the measurement target component table 700, respectively. If it is determined that the control button 503 is selected, the caption of the control button 503 is changed from, for example, "measurement start" to "measurement end", and the process proceeds to step S407. If it is determined that the data has not been selected, an error message is displayed, the process returns to step S404, and the user is prompted to select the component data to be measured.

In step S407, the CPU 201 of the information processing apparatus 101 executes a process for calculating the shortest distance between the component data selected in step S404. Details of the shortest distance calculation process are shown in FIG. 8, which will be described later.

In step S408, the CPU 201 of the information processing device 101 uses the input receiving unit 322 to determine whether or not the CSV output button 508 is pressed on the shortest distance measurement screen 500. If it is determined that the CSV output button 508 is pressed, the process proceeds to step S409, and if it is determined that the CSV output button 508 is not pressed, the process proceeds to step S410.

In step S409, the CPU 201 of the information processing apparatus 101 uses the CSV output unit 323 to store the measurement ID 721, the shortest distance 722, the X coordinate a723, the X coordinate b724, and the Y coordinate stored in the shortest distance measurement table 720 shown in FIG. The a725, the Y coordinate b726, the Z coordinate a727, and the Z coordinate b728 are output to a CSV format file (file output means). This output format is not limited to CSV format files.

The shortest distance measurement table 720 is a table stored in the storage unit 301 of the information processing device 101. The shortest distance measurement table 720 is composed of measurement ID 721, shortest distance 722, X coordinate a723, X coordinate b724, Y coordinate a725, Y coordinate b726, Z coordinate a727, and Z coordinate b728. The measurement ID 721 is issued every time the shortest distance is acquired in the process described later, and is uniquely identifiable information. The shortest distance 722 is information indicating the shortest distance between the selected component data to be measured. In particular, the shortest distance between the first component data and the second component data when the first component data is operated according to the moving portion is shown. The X coordinate a723, the X coordinate b724, the Y coordinate a725, the Y coordinate b726, the Z coordinate a727, and the Z coordinate b728 are coordinate values indicating the start point and the end point of the straight line indicating the shortest distance. The X coordinate a723, the Y coordinate a725, and the Z coordinate a727 are coordinate values indicating the start point, and the X coordinate b724, the Y coordinate b726, and the Z coordinate b728 are coordinate values indicating the end point.

In step S410, the CPU 201 of the information processing device 101 closes the shortest distance measurement screen 500 by detecting the pressing of the close button 509 of the shortest distance measurement screen 500 by using the input reception unit 322, and closes the shortest distance measurement program 320. Finish the startup of.

Next, the shortest distance measurement process will be described with reference to FIG. In the shortest distance measurement process, the part data selected in step S404 is operated in the range of motion instructed by the user, and the shortest distance between the part data is continuously acquired during the operation. Then, among the plurality of acquired shortest distances, the shortest distance (closest distance) at which the component data are closest to each other is specified as the closest distance. That is, the closest distance between the component data in the range of motion can be obtained only by the user operating the selected component data in an arbitrary range of motion. This description will be described below.

First, in step S801, the CPU 201 of the information processing device 101 switches the three-dimensional CAD application 310 to a mode for measuring the shortest distance. More specifically, the shortest distance acquisition instruction unit 324 is used to instruct the shortest distance acquisition unit 312 to acquire the shortest distance. Upon receiving the instruction, the shortest distance acquisition unit 312 instructs the mode switching unit 313 to switch to the mode for measuring the shortest distance. The mode switching unit 313 switches to the mode accordingly. When the mode is switched to the mode for specifying the shortest distance, each process of step S803 to step S812, which will be described later, is executed every time the component data is operated according to the movable portion.

In step S802, the CPU 201 of the information processing device 101 determines whether or not the component data of the measurement target including the movable portion has been dragged by the user through the input device 209. That is, it is determined whether or not there is an operation instruction from the user. If it is determined that the operation instruction has been given, the process proceeds to step S803, and if not, the process proceeds to step S813.

In step S803, the CPU 201 of the information processing apparatus 101 uses the 3D model control unit 311 to accept a drag operation of the component data (first component data) including the movable portion displayed by the 3D CAD application 310. Then, the component data is operated in the movable range corresponding to the drag operation. That is, the operation is performed in the range of motion of the component data in which the user drags the data.

In step S804, the CPU 201 of the information processing device 101 uses the distance measuring unit 314 to measure the shortest distance between component data to be measured at regular measurement intervals (measurement control means). In the present embodiment, the first component data 601 provided with the movable portion is operated in step S803, and the first component data 601 and the second component data 602 different from the first component data 601 are Measure the shortest distance. The measured shortest distance is passed to the shortest distance acquisition unit 312, and is passed from the shortest distance acquisition unit 312 to the shortest distance acquisition instruction unit 324.

In step S805, the CPU 201 of the information processing apparatus 101 uses the shortest distance acquisition instruction unit 324 to store the shortest distance acquired in step S804 in the shortest distance measurement table 720. More specifically, a new record is created in the shortest distance measurement table 720, and a new unique identification information is issued to the measurement ID 721. Then, the shortest distance acquired in step S804 is stored in the shortest distance 722 of the record, and the X coordinate a723, the X coordinate b724, the Y coordinate a725, the Y coordinate b726, the Z coordinate a727, and the Z coordinate b728 are measured in step S804. The coordinate values indicating the start point and end point of the straight line indicating the shortest distance are stored. In this way, the shortest distance at a certain operating position is recorded.

In step S806, the CPU 201 of the information processing apparatus 101 uses the screen display control unit 321 to display each information of the shortest distance measurement table 720 updated in step S805 on the measurement point list 507 provided on the shortest distance measurement screen 500 (. List display means). For example, as shown in the measurement point list 507 of the shortest distance measurement screen 500 of FIG. 9, the shortest distance and the coordinate value indicated by the shortest distance are displayed.

In step S807, the CPU 201 of the information processing apparatus 101 uses the operating state acquisition unit 315 to acquire the operating state of the component data to be measured including the movable portion at the time when the shortest distance is measured in step S804. The shortest distance acquisition unit 312 instructs the operation state acquisition unit 315 to acquire the operating state of the first component data 601 at the time when the shortest distance is measured, in response to the instruction from the shortest distance acquisition instruction unit 324. The operating state acquisition unit 315 acquires the operating state of the first component data 601 and returns it to the shortest distance acquisition unit 312, and the shortest distance acquisition unit 312 returns it to the shortest distance acquisition instruction unit 324 as a result.

In step S808, the CPU 201 of the information processing apparatus 101 uses the shortest distance acquisition instruction unit 324 to store the information regarding the operating state acquired in step S807 in the operating state history table 710 as shown in FIG. 7.

The operation state history table 710 is a table stored in the storage unit 301 of the information processing device 101. The operation state history table 710 is composed of a measurement ID 711, a measurement target part name 712, an origin coordinate value 713, an X-axis vector 714, a Y-axis vector 715, and a Z-axis vector 716. The measurement ID 711 is identification information corresponding to the measurement ID 721 of the shortest distance measurement table 720. The same information as the measurement ID 721 issued in step S805 is stored in the measurement ID 721. That is, the operating state is stored for each measured shortest distance. The measurement target component name 712 indicates the name of the measurement target component data including the movable portion. That is, of the measurement target part name a701 or the measurement target part name b702 in the measurement target component table 700, the component name of the component data including the movable portion is stored. The origin coordinate value 713 stores the coordinate value of the origin set in the component data indicated by the measurement target component name 712. It is not the coordinate value of the origin of the assembly data that is the active document, but the coordinate value of the origin set for each part data. Further, the X-axis vector 714, the Y-axis vector 715, and the Z-axis vector 716 store the directions and angles of the component data indicated by the measurement target component name 712. In this way, the operating state of the component data to be measured including the movable portion at the time when the shortest distance is measured in step S804 is stored in the operating state history table 710.

In step S809, the CPU 201 of the information processing device 101 uses the shortest distance identification display instruction unit 326 to instruct the shortest distance identification display control unit 316 to identify and display the shortest distance measured in step S804 in the three-dimensional space. (Display control means). Upon receiving the instruction, the shortest distance identification display control unit 316 identifies and displays the shortest distance between the first component data and the second component data. For example, as shown in the processing image 910 of FIG. 9, the shortest distance is measured by operating the movable portion of the first component data 601 and is identified and displayed as a straight arrow 911 indicating the shortest distance. The arrow 911 points to the back side of the second component data 602.

In step S810, the CPU 201 of the information processing device 101 measures in step S804 using the closest distance determination unit 325, and is the shortest distance stored in the shortest distance measurement table 720 in step S805 the closest distance? Judge whether or not (closest distance identification means). More specifically, when the closest distance 732 of the closest distance table 730 as shown in FIG. 7 and the shortest distance 722 newly stored in step S805 are compared, the value of the shortest distance 722 is smaller. The process proceeds to step S811. If not, the process proceeds to step S812. When the shortest distance is acquired for the first time, nothing is stored in the closest distance 732, so the process proceeds to step S811. By doing so, each time a drag operation is accepted, whether or not the measured shortest distance is the closest distance (closest distance) to the component data to be measured among the shortest distances measured so far. Can be specified.

The closest distance table 730 is a table stored in the storage unit 301 of the information processing device 101. The closest distance table 730 is composed of the measurement ID 731 and the closest distance 732. The measurement ID 731 is identification information corresponding to the measurement ID 721. The closest distance 732 indicates the shortest distance 722 of the measurement ID 721 corresponding to the measurement ID 731.

In step S811, the CPU 201 of the information processing apparatus 101 is determined to be the closest distance in step S810, so the shortest distance measured in step S804 is recorded as the closest distance. At the same time, the closest distance recorded in the closest distance column 506 of the shortest distance measurement screen 500 is displayed. More specifically, the measurement ID 721 stored in step S805 is stored in the measurement ID 731, and the shortest distance 722 also stored in step S805 is stored in the closest distance 732. In either case, if the value is already stored, it will be overwritten. However, if the shortest distance 722 shows the same value as the closest distance 732, a new record is added. In this way, the closest distance can be specified by determining whether or not the shortest distance just measured is the closest distance each time the measurement is performed, and if it is the closest distance, overwriting and saving the distance. That is, since the shortest distance is measured at predetermined intervals, it is desirable to operate the component data so as to satisfy the range of motion that the user wants to operate so that there is no measurement omission. By doing so, it is possible to prevent a specific omission of the closest approach distance. Further, even if there are a plurality of closest distances having the same distance, they can be recorded.

In step S812, the CPU 201 of the information processing device 101 determines whether or not the drag operation from the user for the component data to be measured including the movable portion is continued. If it is determined that the process is continued, the process returns to step S803. If it is determined that the process is not continued, the process proceeds to step S813. That is, while the drag operation is continued, each process of step S803 to step S812 is continued. That is, the shortest distance is continuously measured in step S804 while the component data of the measurement target including the movable part is being operated, the shortest measured distance is additionally displayed in the measurement point list 507 at any time, and the closest distance in step S810. If the distance is smaller than the closest distance recorded so far, the measured shortest distance is newly recorded as the closest distance.

In step S813, the CPU 201 of the information processing device 101 uses the input reception unit 322 to determine whether or not the preview button 504 provided on the shortest distance measurement screen 500 has been pressed. The preview button 504 is a button for reproducing the operating state when the shortest distance recorded as the closest distance is measured. If it is determined that the preview button 504 has been pressed, the process proceeds to step S814. If it is determined that the preview button 504 is not pressed, the process proceeds to step S818.

In step S814, the CPU 201 of the information processing apparatus 101 uses the screen display control unit 321 to identify and display the closest distance stored in the closest distance table 730 in the measurement point list 507. The shortest distance displayed in the measurement point list 507 is a list of information stored in the shortest distance measurement table 720. That is, a record having the same measurement ID 721 as the measurement ID 731 of the closest approach distance table 730 is specified, and the row corresponding to this record is identified and displayed in the measurement point list 507. On the shortest distance measurement screen 500 shown in FIG. 9, "149.172" is displayed in the closest distance column 506. In other words, this is the closest distance. Since the record corresponding to this closest distance is the record shown in 901, it is identified and displayed. The background may be inverted as shown in 901, or the character color may be changed. The method of identification display is not particularly limited.

In step S815, the CPU 201 of the information processing device 101 reproduces the operating state when the closest approach distance is measured (reproduction means). More specifically, the closest approach state reproduction instruction unit 327 identifies the measurement ID 711 that matches the measurement ID 731 of the closest approach distance table 730, and uses the information stored in the record having the measurement ID 711 to determine the operating state. An instruction is given to the closest approach state reproduction control unit 317 so as to reproduce. Upon receiving this, the closest approach state reproduction control unit 317 operates the component data shown in the measurement target component name 712 based on the origin coordinate value 713, the X-axis vector 714, the Y-axis vector 715, and the Z-axis vector 716 to operate the closest approach. Reproduce the placement position and orientation when the distance is measured. Further, the shortest distance in this operating state is identified and displayed as shown by an arrow 911. By doing so, the state when the closest approach distance is measured can be reproduced, so that the user can understand the situation that cannot be understood only by the value. In this embodiment, only the operating state of the closest distance is reproduced, but since the operating state is recorded in the operating state history table 710 for each shortest distance, the operating state of each shortest distance should be reproduced. It may be. In this case, a mechanism for reproducing the shortest distance selected by the user in the measurement point list 507 can be considered. A record having a measurement ID 711 that matches the measurement ID 721 of the selected shortest distance may be specified from the operation state history table 710 and reproduced as described above.

In step S816, the CPU 201 of the information processing device 101 determines whether or not there are a plurality of closest distances. As described above in step S811, when the measured shortest distance and the closest distance are the same, a new record is created and recorded in the closest distance table 730. That is, there may be a plurality of closest distances having the same distance. In this case, since it is necessary to present the plurality of operating states to the user, such a determination is made. More specifically, when there are a plurality of records in the closest distance table 730, it is determined that there are a plurality of closest distances. If it is determined that there are a plurality of closest distances, the process proceeds to step S817, and if it is determined that there are not a plurality of closest distances, the process proceeds to step S818.

In step S817, the CPU 201 of the information processing device 101 uses the input reception unit 322 to determine whether or not the next button 505 provided on the shortest distance measurement screen 500 is pressed. Next, when it is determined that the button 505 is pressed, the process is returned to step S815 to reproduce the operating state of the closest distance that has not been reproduced yet. In this way, each time the next button 505 is pressed, another operating state at the closest distance can be reproduced. Next If it is not determined that the button 505 has been pressed, the process proceeds to step S818. In the processed image 920 of FIG. 9, the operating state when the closest approach distance different from the closest approach distance reproduced in the processed image 910 is measured is reproduced. When the next button 505 is pressed, the first component data 601 is operated and displayed in the state shown in the processing image 920.

In step S818, the CPU 201 of the information processing apparatus 101 uses the input receiving unit 322 to determine whether or not the control button 503 indicating "measurement end" provided on the shortest distance measurement screen 500 has been pressed. When it is determined that the control button 503 is pressed, the caption of the control button 503 is changed from "measurement end" to "measurement start", and the process proceeds to step S819. If it is not determined that the control button 503 has been pressed, the process returns to step S802.

In step S809, the CPU 201 of the information processing apparatus 101 returns the mode switched in step S801 to the original normal mode. More specifically, the shortest distance acquisition instruction unit 324 instructs the shortest distance acquisition unit 312 to end the acquisition of the shortest distance. When the shortest distance acquisition unit 312 receives this and instructs the mode switching unit 313 to return to the normal mode, the mode switching unit 313 switches from the mode for measuring the shortest distance to the normal mode. As described above, the normal mode is a mode in which the shortest distance is not measured even if the component data including the moving portion is dragged. After switching to this normal mode, the shortest distance measurement process is terminated, and the process proceeds to step S408 described above.

As described above, according to the present embodiment, the part data that operates in the range of motion of the part data having the movable part and that operates in the range of motion according to the instruction from the user, and the part data that is different from the part data. Since the closest distance can be easily specified, it is possible to reduce the labor of the operator without relying on the experience and intuition of the operator.
