  Here, an example in which the present invention is applied to a design support apparatus (CAD) which is an aspect of the drawing creation support apparatus will be described.

(1) Hardware Configuration FIG. 1 shows the hardware configuration of the design support apparatus of this embodiment. The hardware configuration includes a bus 12, an arithmetic processing unit 11, a main storage unit 13, an image processing unit 14, a monitor 15 as a screen display unit, an input / output processing unit 16, a data recording unit 17, a keyboard 18, and a mouse 19. Computer system. The arithmetic processing unit 11, the image processing unit 14, the input / output processing unit 16, and the data recording unit 17 are connected to each other via a bus 12 so as to communicate with each other.

  The arithmetic processing unit 11 reads the design support program and the design drawing data recorded in the data recording unit 17, stores them in the main storage unit 13 together with the input data sent from the input / output processing unit 16, and executes the design support program The graphic to be displayed on the monitor 15 is sent to the image processing unit 14. The data to be stored is sent to the data recording unit 17 via the input / output processing unit 16.

The image processing unit 14 receives the image data sent from the arithmetic processing unit 11 and outputs a graphic to the monitor 15. The input / output processing unit 16 is connected to the arithmetic processing unit 11, the data recording unit 17, the keyboard 18, and the mouse 19 through the bus 12. The input / output processing unit 16 is an interface for the arithmetic processing unit 11 to access the data recording unit 17, the keyboard 18 and the mouse 19.
(2) Display Change of Component Dependency In the design support apparatus having the above configuration, a technique for displaying the dependency relationship of components to be arranged and making it possible to change without mutual interference or contradiction of components on the drawing will be described below. Here, a case where a design drawing of a product composed of a plurality of parts is created will be described as an example.

  FIG. 2 shows a conceptual diagram of a design drawing to be created using the apparatus of the present invention. In the design example described below, the product includes a part A21, a part B22, and a part C23. The component B22 is arranged at a fixed distance 24 from the specified position 153 of the component A21, and the component C23 is arranged at a fixed distance 25 from the specified position 154 of the component B22. That is, the component B22 depends on the arrangement of the component A21, and the component C23 depends on the arrangement of the component B22.

  In the design support apparatus of the present invention, each component 21, 22, 23 arranged is handled as an individual object. Since the component A21 is a reference for the arrangement of the component B22, the component A21 is defined as a reference object for the component B22. Similarly, the part B22 is defined as a reference object of the part C23. Conversely, the component B22 is defined as a dependency object of the component A21, and the component C23 is defined as a dependency object of the component B22.

  During operation of the design support apparatus, the main storage unit 13 stores the parts A21, B22, and C23 as individual objects. For each of a plurality of design drawing data including the entire product, object definition data relating to the object arrangement including the position and shape of the parts is stored in the main storage unit 13. The main storage unit 13 stores an arrangement rule list that is information for specifying an arrangement rule and an arrangement function that is an execution program for the arrangement rule.

  FIG. 3 shows an example of data items constituting the object definition data and data stored for each item. The object definition data includes object name, shape, size, placement rule number, parameter value, reference object number, and position data with the object number as a key.

  Each object has an object name corresponding to the object number on a one-to-one basis. Object specifying information is specified for each object number.

  The shape is data for determining the shape when the object is drawn, and may be a general concept such as a circle or a rectangle, or may be defined by a specific part type name or model name. The size is one or a plurality of data that determines the size when the object is drawn. If the shape is a rectangle, the width and length are stored. The size breakdown is defined for each shape. For example, the radius value is stored if the shape is circular, and the length and width values are stored if the shape is rectangular. When a shape is defined by a specific model name, a plurality of data necessary for geometrically and uniquely determining an object shape to be drawn is stored.

  The position is composed of coordinate data for uniquely determining the position of the object, and the position of the object is defined in advance for each shape. For example, if the shape is a circle, the center X and Y coordinates are recorded, and if the shape is a rectangle, the X and Y coordinates of the vertex located at the lower right are recorded.

  Next, the arrangement rule number, parameter value, and reference object number, which are data necessary for calculating the position, will be described. The placement rule number, which is placement rule specifying information, is a number for extracting the placement rule used when calculating the position of the object from a plurality of placement rules included in the placement rule list stored in the main memory 13. is there. It is also used to extract a placement function to be executed for calculating the position of the object from a plurality of placement functions stored in the main memory 13. The parameter value is a numerical value indicating an amount such as a distance or an angle from the position of another object as a position reference. The reference object number that is the arrangement dependency relationship information is the object number of another object that is used as the reference position for the amount specified by the parameter value.

  For a plurality of objects, the same arrangement rule number may be stored in each object definition data. Even if the arrangement rule number is the same, the position calculated for each object differs if the parameter value or the reference object number stored in each object definition data is different.

  In the example of FIG. 2 described above, the object number of the part B22 is stored as the reference object number in the object definition data of the part C23. In the object definition data of the part C23, a numerical value of the distance 25 is stored as a parameter value.

  As described above, the object definition data format may be stored in a plurality of tables linked with object numbers as keys as shown in FIG. 4, for example, instead of storing the data in a slip format for each object. Good.

  Next, arrangement rule explanation information related to the arrangement rule number will be described with reference to FIG. FIG. 5 shows an example of data items constituting the arrangement rule list and data stored for each item. The arrangement rule list is a set of data including a specific arrangement rule name, an arrangement rule sentence, and unit information for each arrangement rule number, and the arrangement rule number is the same as the arrangement rule number of the object definition data. The placement rule name is a name given to each placement rule number. The arrangement rule sentence and unit are arrangement rule explanation information that is displayed on the screen so that the arrangement rule to which the object is applied can be easily understood by the user. One or a plurality of executable programs uniquely determined for each placement rule number is prepared as a placement function and stored in the main storage unit 13. When the placement function is executed, each object is placed on the drawing. To do.

A group number and group name common to objects of the same shape may be added to the object number and object name in FIG. 3, and the shape and reference object number may be stored using the group number as a key. In this case, it is possible to perform a process of arranging a plurality of objects having the same shape at the same time.
(3) Graphic Creation Processing Next, execution processing for creating a graphic with the design support apparatus will be described. FIG. 6 is a state transition diagram mainly showing those related to the present invention among the execution processing for creating a design drawing by the design support device and the state of the design support device as a result of the execution. These processes and states are realized by the program read from the data recording unit 17 being executed by the arithmetic processing unit 11 of the design support apparatus.

  First, in the standby state 101, the design support apparatus is waiting for an existing determination command from the user via the input / output processing unit 16, the keyboard 18, and the mouse 19. When receiving the existing determination command for the selected object, the design support apparatus in the standby state executes the existing determination process 102. As a result of the existing determination process 102, when it is determined that the object definition data has not been registered in the design support apparatus, the new arrangement process 103 is executed to register the data. When the new placement process 103 is completed, the design support apparatus returns to the standby state 101. If it is determined that the object definition data has been registered, the dependency display process 104 is executed. When the dependency relationship display process 104 is completed, the design support apparatus transitions to a parameter input waiting state 106. FIG. 7 shows an example of the screen display in the standby state 101. In this example, three objects of a part A21, a part B22, and a part C23 are displayed. When any object is clicked with the mouse 19 in this state, the design support apparatus accepts an existing determination command for the selected object.

  Next, the parameter input wait state 106 is a state in which the design support apparatus is waiting for either a parameter change instruction or a cancel instruction from the user. When receiving the parameter change command, the design support apparatus in the parameter input waiting state 106 executes the placement update process 105 to rearrange the objects and then returns to the waiting state 101. The design support apparatus returns to the standby state 101 immediately upon receiving the cancel command.

  FIG. 8 shows an example of a screen display in the parameter input waiting state 106. Here, the part B22 is selected as a change target. The reference object name 111, the arrangement rule sentence 121, the unit 123, and the parameter value 122 of the part B22 are displayed. Further, the reference object name 112, the arrangement rule sentence 124, the unit 126, and the parameter value 125 of the part C23 arranged with the part B22 as the reference object are displayed. Each of the parameter values 122 and 125 is in a state where it can be changed upon receiving a value input from the user. In addition, a “parameter change execution” button 127 and a “cancel” button 128 are displayed. In the parameter input waiting state 106, the design support apparatus accepts a parameter change command by clicking the “parameter change execution” button 127. Alternatively, a cancel command is accepted by clicking the “cancel” button 128.

  FIG. 9 shows another screen display example in the parameter input waiting state 106. If the auxiliary lines 129 and 130 for explaining the meaning of the parameter values 122 and 125 are further displayed on the drawing in the display shown in FIG. 8, it helps the user to understand the arrangement rules. Further, if the outlines of the component A21 and the component C23 having the dependency relationship with the component B22 and the specified positions 153 and 155 are highlighted, the user can understand the reference object names 111 and 112. In addition, a plurality of object arrangement rule statements 121 and 124, reference object names 111 and 112, and parameter values 122 and 125 are collectively displayed in one dialog window 131.

Next, details of the new placement processing 103, the dependency relationship display processing 104, and the placement update processing 105 following the existing determination processing 102 in FIG.
(4) New Arrangement Processing FIG. 10 is a flowchart showing the new arrangement processing 103. When the new placement process 103 is started (S101), the design support apparatus performs an object definition data acquisition process (S102). The details of S102 are as follows.

  First, the design support apparatus acquires shape, size, and position data from the figure of the clicked object, and then displays a new setting dialog 51 shown in FIG. In the new setting dialog 51, the arrangement rule name 56 and the reference object name 111 are displayed as a selectable list. Further, the placement rule sentence 121 retrieved from the placement rule list is displayed using the placement rule number corresponding to the selected placement rule name 56 as a key. The parameter value 122 is displayed in a state where it can be input. In addition, a “create new” button 61 and a “cancel” button 62 are displayed. The object name 52 is displayed in a state where an arbitrary name can be input. When the “Cancel” button 62 is clicked, the new placement process 103 is canceled and the process returns to the standby state 101.

  When the “execute new creation” button 61 is clicked, each data input to the new setting dialog 51 is stored as object definition data with the new object number to be automatically assigned as a key, and the process proceeds to the next step. The placement calculation of the objects created in step S103 is performed (S103). Details of the arrangement calculation S103 will be described in the section (6). When the arrangement calculation S103 is completed, the calculation result is acquired and stored as position data of a newly created object (S104). Finally, based on the object definition data, a newly created object graphic is displayed on the screen (S105).

  Although not shown here, as another method, in addition to the shape and size of the new setting dialog 51 shown in FIG. 11, the position is also displayed in a state in which input from the user can be received, and based on the input data Object definition data may be stored. If the shape is not changed and only the size and position are changed, the user only needs to prepare a new set of related parameters, and the object need not be drawn in advance.

Further, in this embodiment, the position only in the X direction is limited and one arrangement rule is defined. However, a plurality of arrangement rules may be defined for one object. Displays multiple reference object names, placement rule statements, parameter values, and units, and displays an inputable dialog. Thereby, for example, an arrangement rule for determining the position of the part in the X direction and an arrangement rule for determining the position in the Y direction can be defined.
(5) Dependency Display Processing Next, the dependency display processing 104 in FIG. 6 will be described. FIG. 12 is a flowchart showing the dependency display processing 104. When an arrangement change preparation command is received (S201), the object number of the clicked object is acquired as the change target object number (S202). Next, a dependent object is extracted using the acquired object number as a key (S203).

  FIG. 13 is a sub-flow diagram showing details of the dependent object extraction processing S203. When the dependency relationship information extraction process is started (S301), the object number of the change target object is acquired as a fixed value N (S302). Next, the following processing is sequentially performed on all objects other than the change target object (S303).

  First, the reference object number is acquired as a variable S (S304). Next, “S = N?” Is determined. If the determination result is Yes, the object number of the object being processed is stored in the main memory 13 as a dependent object (S305). By the processing of S303, the object numbers of all the dependent objects for the change target object are stored in the main memory 13.

  Here, an object number of an object further dependent on the extracted dependent object may be retrieved by processing S203 and added to the main memory 13 and stored. By doing so, dependency information can be displayed for all indirectly dependent parts even if there is no direct dependency, and changes that cause inconsistencies in the arrangement between indirectly dependent parts can be displayed by the user. Can be prevented.

Returning to FIG. 12, after the process of S203, the placement rule statement, parameter value, unit, and reference object name are displayed based on the object definition data of the object to be changed, and the object definition data of the extracted dependent object is displayed. Based on this, the arrangement rule sentence, parameter value, unit, and reference object name are displayed on the screen (S204).
(6) Arrangement Update Process FIG. 14 is a flowchart showing the arrangement update process 105. When the arrangement update processing 105 is started (S401), first, one processing target object is selected (S402). Here, the process target objects are the change target objects whose object numbers have been acquired in the process of S202 and all dependent objects whose object numbers have been stored in the main memory 13 in the process of S203. In the first process, a change target object is selected, and in the second and subsequent processes, dependent objects are sequentially selected.

  Next, the parameter value input for the processing target object is acquired (S403). Next, the position of the reference object is acquired (S404). Next, in order to acquire the position of the processing target object, the layout calculation (S103) in the flowchart of the new layout processing 103 in FIG. 10 is performed.

  FIG. 15 is a subflow diagram showing details of the arrangement calculation S103. When the arrangement calculation is started (S501), first, the parameter value, arrangement rule number, and reference object number of the processing target object are acquired (S502). Next, an arrangement function is selected using the arrangement rule number as a key (S503). Next, the position of the reference object is acquired using the reference object number as a key (S504). Next, the position is calculated by giving the position and parameter value of the reference object to the selected placement function and executing the placement function (S505).

  Here, a specific method for calculating the position of the component C23 will be described. The arrangement function for calculating “XC = XB-PC” is stored in the main storage unit so that it can be called and executed using the arrangement rule number “1101” as a key. This function is executed by giving XB = “X coordinate of the position of the component B22” and PC = “parameter value of the component C23” to this function, and obtains the X coordinate XC of the position of the component C23.

When the arrangement calculation S103 is completed in the flow of FIG. 14, the position data stored in the object definition data is replaced with the position data calculated in the arrangement calculation S103 (S405). Specifically, the X coordinate stored in the object definition data of the part C23 is replaced with the calculated value XC. In this example, the Y coordinate is not changed by the arrangement function, and is not updated. Finally, the object graphic is displayed on the screen (S406).
(7) Functions of Support Device Next, functions realized in the design support device which is an embodiment of the present invention will be described. FIG. 16 is a functional block diagram mainly showing functions related to the present invention among the functions realized in the design support apparatus. The design support apparatus functionally includes a dependency display unit F1, an arrangement update processing unit F2, object definition data d1, an arrangement rule list d2, and an arrangement function d20.

  These functions are realized by, for example, reading a program for executing the processing shown in FIGS. 10 to 15 from the data recording unit 17 and executing the program by the arithmetic processing unit 11.

  Based on the object definition data d1, the dependency relationship display unit F1 searches for an object having a dependency relationship by the dependency object extraction processing S203 of FIG. 12 showing the flow of the dependency relationship display processing 104, and the change target object and the extracted dependency For the object, the description of the arrangement rule acquired from the arrangement rule list d2 using the object number as a key is displayed on the screen.

  The arrangement update processing unit F2 updates the parameter value of the object definition data d1 according to the input from the user. Further, the placement function d20 is selected and executed using the placement rule number stored in the object definition data d1 as a key, the position of the processing target is calculated by the placement calculation S103, and the position data of the object definition data d1 is updated. .

  In the arrangement update processing 105 of the present embodiment described above, only the parameter value can be accepted for change. However, the arrangement rule name 56, the reference object name, and the like can be accepted by selection input. Good. This can be realized by the following form. In the state transition diagram of FIG. 6, first, in the parameter input waiting state 106, when the user clicks on the object, a dependency change process is executed to execute the clicked object new arrangement process 103. At this time, the object definition data already stored for the clicked object is displayed in the new setting dialog 51 shown in FIG. 11 displayed in step S102 in the flow of FIG. In step S102, no new object number is assigned if an existing number has already been stored. By this method, a new arrangement rule can be given between objects or related objects can be changed, and it becomes possible to proceed with a wider and flexible design by trial and error by changing various conditions.

  FIG. 17 shows a display example of the parameter input standby state 101 according to the second embodiment of the present invention. In the second embodiment, allowable ranges 81, 82, 83, and 84 for parameter values are displayed. This display is realized by storing and displaying the minimum value and maximum value of the allowable range as one of the object definition data as shown in FIG.

  This allowable range is realized by adding a step of causing the user to input on the new setting screen shown in FIG. 19 and storing the input value to the process of the object definition data acquisition process S102. The allowable ranges 81, 82, 83, and 84 are effective for providing information to the user just by displaying them, but when a parameter value outside the allowable range is input, a message prompting the user to correct the parameters is displayed. Mistakes can be prevented. Further, by displaying the allowable range in a changeable state and updating the allowable range according to an input value from the user, more flexible design support is possible.

  Alternatively, an allowable range calculation function for determining the allowable range is prepared and stored for each shape as an executable program, and the step of calculating the allowable range by executing the allowable range calculation function is performed in the object definition data acquisition process S102. May be added to

  FIG. 20 shows another example of the dependency relationship display process 104 flow shown in FIG. After the dependent object is extracted in steps S201 to S203, an access restriction that determines whether the user can change the position and parameter value of the object to be changed is determined (S205). The change target object determined to be unchangeable is displayed in a form that does not accept input of parameter values (S205). By this method, when a plurality of users share and create one product or plant, it is possible to prevent mistakes that change the arrangement determined by other users without permission.

  Here, an example of a specific method of the access restriction determination (S205) will be described.

  First, in place of the object definition data described in the embodiment of FIG. 3, object definition data as shown in FIG. 21 in which an item of “parameter value access right level” is added to the included data items is used.

  Further, as shown in FIG. 22, a data set in which the user ID and the value of the access right level determined by the user corresponding to the user ID can be extracted is recorded in the data recording unit 17.

  In the access restriction determination (S205), first, the user ID of the user who is operating the design support apparatus is acquired. The method includes, for example, a method in which a user inputs a user ID when the design support apparatus is first activated, and the input user ID is stored in the main memory 13. Alternatively, when the dependency display processing 104 is started, the user ID may be input by the user.

  The design support apparatus determines whether or not the change can be made based on the access right level corresponding to the acquired user ID and the “parameter value access right level” stored in the object definition data.

  For example, when the determination method is such that the parameter value cannot be changed when the access right level of the user is lower than the access right level of the object, for example, the access right level of the parameter value is “2” and the user of the user who is operating When the access right level corresponding to the ID is “1”, it is determined that the operating user cannot change the parameter value.

  Based on the determination result, the parameter value display method in the dependency relationship display process is changed.

  In FIG. 23, when it is determined that the operating user cannot change the parameter value of the part B22 and the parameter value of the part C23 can be changed, the dependency display information is displayed (S206). An example of the displayed screen is shown.

  The parameter value of the part B22 is displayed surrounded by a dotted line frame 161, and the parameter value of the part C23 is displayed surrounded by a solid line frame 162. Thus, by distinguishing the display, the user can easily understand the data that can be changed and the data that cannot be changed. As a display distinguishing method, the color may be changed or the display location may be changed.

  Further, an item of “position access right level” is added to the object definition data shown in the embodiment of FIG. 3, and it is determined whether or not the user of the operation cannot change the position of the object in the same manner as described above with respect to the parameter value. You may make it do. In this case, when the user moves the object with the mouse or executes the arrangement update processing 105 to update the position of the object, a warning display as shown in FIG. 24 is displayed on the screen. If a series of processing is canceled and the drawing is returned to the state before the processing, it is possible to prevent the user from performing an erroneous update operation.

  FIG. 25 is a schematic diagram of another embodiment of the data storage mode according to the fourth embodiment of the present invention. An object number of an object drawn on one drawing is recorded in the data recording unit 17 as a drawing file 91 composed of data having a plurality of drawing files. The object definition data d1 and the arrangement rule list d2 are recorded in the object database 93 and shared. The arithmetic processing unit 11 stores the object number of the object included in the drawing in the main storage unit for the drawing file being created, and the object definition recorded in the object database using the object number as a key in each process described above. Data d1 and arrangement rule list d2 are read and processed. With this form, when one product is designed by dividing it into multiple drawing files, it becomes possible to share the layout settings depending on the objects placed in other drawings with other drawings. It becomes easy.

  FIG. 26 is a flowchart of parameter back-calculation processing in the embodiment of the design support system to which a function for back-calculating parameters is added according to the fifth embodiment of the present invention.

  This process is started when the object position is arbitrarily changed by dragging the mouse 19 instead of clicking the “parameter change execution” button in the parameter input waiting state 106 (S601).

  First, an object whose position has been changed is set as a change target object, and the changed position is acquired (S602). Next, the position of the reference object is acquired using the reference object number of the change target object as a key. Next, a parameter reverse calculation function is selected from the arrangement rule number of the change target object (S603). Next, the parameter value is calculated by giving the position of the reference object and the position of the object to be changed to the parameter inverse calculation function and executing it (S604). The calculated parameter value is stored as the parameter value of the change target object (S604).
