JP5630703B2 - Command menu management module - Google Patents

Description

  The present invention relates to a command menu management module as a user interface mounted on a computer system such as a CAD (Computer Aided Design) system.

  In a conventional graphic processing apparatus including a CAD system, a central processing unit that processes input information, a command menu area that displays commands, and a graphic drawing (drawing) area that displays graphic elements including lines, circles, and the like. It has a monitor as an output device having two areas and a pointing device (mouse, digitizer, etc.) as an input operation device. The pointing device is used to select arbitrary position information on the monitor screen and a processing command displayed on the monitor screen, and has buttons for selecting a command and determining a processing position. For example, at the time of drawing, the operator moves the pointing device to the command menu area where processing commands are arranged, points to the processing command desired by the operator, and then operates the enter button to determine the command. To do. Next, the pointing device is moved to the figure drawing area where the drawing is actually performed, and after pointing to a desired point, the decision button is operated to decide. The figure is drawn by repeating such an operation. That is, it is necessary to frequently move the pointing device (actually the pointing position of the pointing device) on the screen of the monitor between the command menu area and the figure drawing area, resulting in interruption of thinking. In order to avoid this problem, Patent Document 1 is configured so that two pointing devices are used, one dedicated to the command menu area and the other dedicated to the graphic drawing area. A graphic processing apparatus is described in which the separation between the command menu area and the graphic drawing area by the pointing device is significantly reduced by separating. However, in this apparatus, even if the movement of the pointing device between the command menu area and the graphic drawing area is reduced, it is necessary to operate each pointing device with both hands. A new problem arises that requires space for two pointing devices.

  As another method for reducing the traffic between the command menu area and the graphic drawing area, Patent Document 2 discloses that a plurality of command menu types and their types are displayed on the screen when a mouse button is pressed for a predetermined time after the drawing mode is started. When a menu guide indicating the direction of the mouse for selecting is displayed, and the mouse is moved in any of the up, down, left, and right directions based on the guide display of the menu guide, the key input signal from the mouse and the XY direction of the mouse are displayed. The mouse movement signal is determined in one of up, down, left and right directions from the minute movement signal of the mouse, and a command menu set in advance corresponding to each of the mouse movement directions is selected by the mouse movement signal. A command menu display method of displaying on the screen is described. In this method, when moving toward the menu guide displayed around the mouse (mouse cursor), the command menu is displayed, so there is no need to go back and forth between the command menu area and the drawing area for each drawing event. Since the area where the menu is displayed is limited to the vicinity of the mouse cursor, when the number of commands is large as in the case of CAD, the menu display area becomes large and it is difficult to see.

JP-A-5-174121 (paragraph number [0004-0014], FIG. 1) JP 2000-339482 A (paragraph number [0004], FIG. 1)

  In view of the above circumstances, an object of the present invention is to simplify an operation of selecting a command to be used from a large number of commands.

In order to achieve the above object, the command menu management module according to the present invention divides the work area defined on the monitor screen into a plurality of sections, and at least one selected from a command group related to operations for the sections. A sub-command menu allocating unit for assigning a sub-command menu including the command, and a sub-command menu allocated to a section including an instruction (cursor) position on the monitor screen of the input operation device for command selection by the input operation device A command display requesting unit for displaying the input operation information based on the input operation of the input operation device with the command selected through the subcommand menu ,
The command display request unit is capable of selecting a boundary display request function for displaying the boundary of the section on a monitor screen and a boundary non-display request function for not displaying the boundary on the monitor screen, and the command display request unit includes: The boundary is not displayed on the monitor screen while a command is selected by the input operation device through the subcommand menu .

  According to this configuration, the command can be selected in the work area defined on the monitor screen, so it is usually necessary to move to the command menu area defined in the peripheral area of the monitor screen in order to select the command. Disappears. Furthermore, since a different command can be assigned to each section divided from the work area, a subset of mutually related commands selected from a large number of command groups can be assigned to each section as a subcommand menu. For this reason, even if a large number of drawing commands are prepared as in the CAD system, for example, commands can be assigned to each section of the work area in an appropriately selected form, and command selection can be performed in that section. Thereby, time waste of command selection during work is suppressed, and work comfort is improved.

  When selecting commands from a large number of command groups and subsetting them as subcommand menus, it is convenient to select a command subset for each section by classifying or hierarchizing based on the work type or work procedure. is there. Therefore, it is proposed that the command group is classified for each similar operation, and the subcommand menu is generated for each classification.

In this command menu management, since the command assigned to each section, and thus the command displayed for each section, is different, the operator needs to know the position of each section area in the work area. In order to distinguish each partition from other partitions, it is preferable to display the partition boundary by, for example, a partition boundary line, a partition boundary point, a partition boundary symbol, and a partition boundary surface. However, the display of the partition boundaries becomes an obstacle when working while looking at the actual monitor screen. In addition, such a partition boundary display is not so important for an operator who has mastered to some extent. For this reason, in the present invention , the command display request unit further has a boundary display request function for displaying the boundary of the section on the monitor screen and a boundary non-display request function for not displaying the boundary on the monitor screen. In addition, since the display and non-display of the boundary can be selected, usability is improved.

Regarding the display and non-display of the boundary, since it is desirable to clarify each section when selecting and exchanging commands, the display of the boundary is convenient, and the display of the boundary is not necessary when working with the command once selected. From this viewpoint, in the present invention , the command display request unit is further configured not to display the boundary on the monitor screen while a command is selected by the input operation device through the subcommand menu.

Regarding the display of the sub-command menu assigned to each section, the following two methods are proposed, but it is desirable to have both methods as functions, but it may be possible to select and set either of them.
(1) When the instruction (cursor) position of the input operation device reaches the section, the subcommand menu assigned to the section is automatically displayed.
(2) When an input (cursor) position of the input operation device is input in the section, the subcommand menu assigned to the section is displayed.
The method (1) is called a dynamic pop menu method, which eliminates the need for an operation for displaying a menu, thus making the operation easier. Furthermore, since the subcommand menu appears sequentially by moving the instruction (cursor) position of the input operation device on the monitor screen, it is convenient when searching for commands. In the method (2), since the subcommand menu is displayed for the first time by some operation on the input operation device, an unnecessary subcommand menu is displayed while the input (cursor) position of the input operation device is moved to the target section. This eliminates the hassle.

  The central area of the work screen is usually likely to display important and core information. Therefore, it is often not desirable that such an important work area is not visible or difficult to see even for command switching. Accordingly, it is preferable that the section is set in the peripheral area of the monitor screen and not set as a section in which the subcommand menu is displayed in the central area of the work area.

It is a schematic diagram which shows the flow of basic control of the command menu management module by this invention. It is a functional block diagram in the example mounted in the CAD system as embodiment of the command menu management module by this invention. It is a basic monitor screen figure in a CAD system. It is a screen figure which shows an example of a boundary setting dialog. It is a screen figure which shows an example of an allocation setting diagram. It is a flowchart of a command menu management setting process. It is a flowchart of a drawing process. It is a flowchart of a command selection process. It is a flowchart of the drawing process in another embodiment. It is a screen figure which shows an example of the allocation setting dialog which allocates a command to an element object.

First, the basic control flow when the command menu management module according to the present invention is installed in a drawing system will be described with reference to the schematic diagram shown in FIG. Here, a mouse is used as the input operation device, and an input instruction position in the input operation on the monitor operation operation screen is a mouse cursor position (hereinafter simply referred to as a mouse position).
This command menu management process is divided into a pre-setting process and an execution process. In the pre-setting process, the drawing area as the work area is divided into a plurality of sections. Conceptually, a command menu assignment layer is created as a lower layer of a drawing layer (drawing area) that draws graphic objects such as lines and lines, and text objects such as characters. Partition into six sections from section 1 to section 6 (# 01). Next, commands that may be used from the operation command group possessed by the CAD system are appropriately classified so as to be easy to use, and distributed to six or less subcommand menus (# 02). For example, in the example of FIG. 1, command 1 and command 4 are grouped and included in one subcommand menu, command 7 and command 9 are grouped and included in another subcommand menu, command 3 and command 5 Are grouped and included in yet another subcommand menu. The commands distributed in the form of a plurality of subcommand menus in this way are assigned to each section in the command menu assignment layer (# 03). As a result, commands that may be used are registered in the subcommand menu registration table for each section for each section. In the subcommand menu registration table for each section, the section reference coordinate position: (x, y) and section size: u × v on the command menu assignment layer of each section, that is, on the drawing layer (the section shape is rectangular) ) Is also recorded (# 04). Through this table, it is possible to specify a section containing the mouse position, and to read out a subcommand menu assigned to the specified section, that is, one or more classified commands.

When the above-described pre-setting process is completed, the command selection through the command menu display as described below is performed by starting the execution process of the command menu management in the work operation on the actual work screen.
In the stage before command selection by the mouse operation, a partition boundary line as a partition boundary indicating the partitioned partition is displayed in the actual work area of the monitor (# 11). When the mouse position indicated by the cursor enters the drawing area, a section including the mouse position is calculated. If a subcommand menu is assigned to the calculated section, the subcommand menu screen is created and displayed as a pop-up menu near the mouse position (# 12). When the pop-up menu is set to the dynamic display mode, the subcommand menu assigned to the specific section is displayed on condition that the mouse position is in the specific section. As display modes other than the dynamic display mode, there is a click trigger display mode in which a mouse command is used as a trigger to display a subcommand menu assigned to a section including the click point. If there is no command you want to use in the displayed subcommand menu, move to the adjacent section. When entering an adjacent section, the subcommand menu screen assigned to this adjacent section is created instead of the subcommand menu assigned to the previously specified section, and is displayed near the mouse position. .

  If there is a command to be used on the subcommand menu screen displayed here, the command is selected for the work to be performed by moving the mouse cursor over the command and clicking (# 13). When a command to be used is selected, the command boundary in the work area is obstructed, so that the partition boundary is not displayed (# 14). When the command work, for example, drawing of a straight line, circle, rectangle, etc., is finished, the command is not selected and the subcommand menu screen is displayed again.

When only one command is assigned to the divided section, that is, when it is not necessary to select a command from the sub-command menu screen, the present invention has one of the following forms (a) and (b) May be incorporated in advance, or a configuration may be adopted in which either (a) or (b) is selected in advance by the user.
(A) Even if the mouse position enters a section to which only one command is assigned, the subcommand menu screen is not displayed, and the only command is automatically selected through some operation event such as mouse click. Configure.
(B) When the mouse position enters the section to which only one command is assigned, a subcommand menu screen including only one command is displayed, and the command is selected by clicking the mouse or the like. At that time, since there is only one option, it is convenient to specify any position for the mouse click or the like.

  Furthermore, if the subcommand menu is not assigned to the divided section, the subcommand menu is not displayed even if the mouse position enters the section. For this reason, considering that there is a high possibility that important and core information is displayed in the center of the drawing area displayed on the monitor screen, the center of the drawing area in the divided sections is displayed. It is convenient to avoid assigning subcommand menus to the compartments that are located, or to disable assignment.

Hereinafter, as an embodiment of the present invention, an example in which a command menu management module is installed in a CAD system will be described. FIG. 2 is a functional block diagram of such a CAD system.
This CAD system is essentially a CAD main body 1 constructed by an OS and a CAD program installed in a computer, a command menu management module 5 incorporated in the CAD program in the form of plug-in software, and the like as a pointing device. The mouse 2 is an example of a functioning input operation device, the monitor 3 is an output device, and the file storage unit 4 is a data storage device including a hard disk.

  As a basic functional unit related to the present invention included in the CAD main body 5, the CAD processing unit 10, the file management unit 11, the display control unit 12, the command storage unit 13, the command processing unit are known per se. 14 and a drawing unit 15. The CAD processing unit 10 has a core function for managing each process in the CAD system, and performs drawing work management, dimension entry management, dimension and shape check based on measurement of dimensions and areas, format conversion, and the like. The file management unit 11 transfers files to be subjected to CAD processing to and from the file storage unit 4. The display control unit 12 displays drawing data and other information developed on the working memory (RAM) on the monitor 3. The command storage unit 13 stores commands used for drawing work and file processing in a hierarchical structure. The command processing unit 14 performs data processing and file processing based on the used command. If the used command relates to drawing, the command processing unit 14 transfers the command script to the drawing unit 15 to perform drawing based on the command. Do it on memory. The drawing result is displayed on the monitor 3 through the display control unit 12. Although not shown in FIG. 2, the drawing data developed in the working memory is output to a printer or plotter via the print control unit, so that a hard copy can be made on the paper at an arbitrary scale.

  The command menu management module 5 displays, on the basic CAD function of the CAD main body, a pop-up menu consisting of different commands for each section defined by dividing the monitor screen described with reference to FIG. A function for enabling command selection is added. Of course, the additional function provided by the command menu management module 5 can be incorporated in the CAD main body program instead of the plug-in module. The command menu management module 5 includes a sub-command menu generating unit 51, a sub-command menu assigning unit 52, a command display requesting unit 53, and a command input processing unit 54 as representative functional units. It is controlled by the management unit 50.

  The subcommand menu assignment unit 52 has a function of dividing the drawing area 6 a into a plurality of sections 60 and assigning the subcommand menu to the sections 60. The CAD system work window defined on the display screen (abbreviated as the monitor screen) of the monitor 3 includes a drawing area (drawing area) 6a and a menu area 6b as work areas as shown in FIG. And are included. This section setting is performed through a boundary setting dialog as shown in FIG. The boundary setting dialog in this example includes an attribute setting area for setting the color and line type that are attributes of the boundary line that bounds the section, the number of divisions in the X direction (horizontal screen direction), and the Y direction (vertical screen direction). A division number setting area for setting the division number is included. For example, if the number of divisions in the X direction is set to “3” and the number of divisions in the Y direction is entered as “2”, the drawing area 6a is indicated by the drawing number 60 from section 1 to section 6 as shown in FIG. Divided into 6 sections. Further, the subcommand menu assigning unit 52 has a function of assigning one or more commands selected from the command group related to the drawing operation and the file operation to one of the plurality of divided sections. The assignment of the subcommand menu to the section is performed through an assignment setting diagram as shown in FIG. In this assignment setting diagram, a section selection area for selectively displaying a plurality of sections (section 1 to section 6) set in advance and a command selection area for selectively displaying a command group available in this CAD system. And various setting buttons. As is apparent from FIG. 5, the setting method is to select a specific section, for example, section 1, and assign a command to the section 1, for example, a circle (center) that is a command for drawing a circle centered on the mouse position. A circle (center) command is assigned to the section 1 by selecting a command and clicking an arrow button which is an assignment combination button. Since multiple commands can be assigned to one partition, this assignment operation may be repeated, or multiple commands can be assigned to one partition at a time by selecting multiple commands and clicking the arrow buttons. May be assigned. The assignment information in which the command is assigned to the specific section by the subcommand menu assignment unit 52 in this way is transferred to the subcommand menu generation unit 51. The subcommand menu generation unit 51 generates a subcommand menu in which at least one command assigned to each section is converted into a menu based on the assignment information.

  The subcommand menu may be generated in advance before the command assignment operation, and the generated subcommand menu may be assigned to a specific section. In addition, since the command group is classified for each similar work, if a configuration in which a subcommand menu is generated for each classification is adopted, a command for similar work is assigned to the same section. Since it is included, it becomes convenient in operation.

  What is important for the present invention is that a subcommand menu including different commands is assigned to a specific section, and when the pointing position of the pointing device such as the mouse 2 enters the specific section, the subcommand menu is assigned to the specific section. The subcommand menu is popped up and displayed. For this purpose, a command display request unit 53 is prepared, and a subcommand is assigned to a section containing a mouse position based on input operation information from a command input processing unit 54 that calculates an operation event such as a mouse position or a mouse click. If a menu is assigned, the display control unit 12 is requested to display the subcommand menu. The request is attached with the display data of the appropriate subcommand menu managed by the subcommand menu generation unit 51 or the data address thereof.

  When a command is selected through the pop-up subcommand menu, the selected command is transferred to the command processing unit 14 by the command management unit 50. The command processing unit 14 applies mouse operation information for the selected command to a well-known drawing algorithm, generates drawing operation data, and provides the drawing unit 15 with the drawing operation data. As a result, a desired figure is drawn in the drawing area.

  In this embodiment, the command display request unit 53 displays a boundary line display request function for displaying on the monitor screen a boundary line that bounds each section set by the subcommand menu assigning unit 52 and the boundary line on the monitor screen. A boundary line non-display request function that is not displayed is selectable. This boundary line is necessary when the mouse position is moved to a desired specific section, but after a command is selected through the subcommand menu, it is necessary until the input operation by the selected command is completed. Not. Accordingly, the boundary line is set to be hidden while a command is selected through the subcommand menu. In this embodiment, a boundary line is displayed as a boundary between sections. However, a boundary point or a boundary symbol (for example, an arrow) may be used as long as the boundary can be determined instead of the boundary line. Further, as a boundary between sections, it may be only partially displayed on the outer periphery of the drawing area and not displayed on the center of the drawing area. Furthermore, the boundary may be clearly indicated by a boundary surface in which a section is identified by area drawing that can be distinguished by color and transparency.

Next, a command menu management procedure for popping up a different command menu for each partition in the CAD system configured as described above will be described with reference to the flowcharts of FIGS.
First, a command menu management setting process, which is a process of assigning a subcommand menu to a section, will be described with reference to FIG. First, in order to create a plurality of virtual sections for dividing the drawing area 6a, a boundary setting dialog as shown in FIG. 4 is displayed (# 01). The boundary line attribute and the number of screen divisions are input through this boundary setting dialog (# 02). A predetermined number of partitions created by this input are numbered to create a partition table used as a subcommand menu registration table (# 03). Next, a command assignment dialog as shown in FIG. 5 is displayed (# 04). Command assignment processing for assigning a desired command to a predetermined section is performed through this command assignment dialog. First, a notable partition is selected by clicking with the mouse, and designated as a partition to which a command is assigned (# 05). A command to be assigned to the designated section is selected (# 06). Since one or more commands can be assigned to one partition, this command selection is repeated until there are no more commands to be selected (# 07). When the command selection for the partition of interest is completed, it is checked whether there is a partition to which a command should be assigned (# 08). If there is still a partition to which a command should be allocated (# 08 No branch), the process returns to step # 05 to repeat the command allocation process for the partition to be noted. When there is no more partition to which a command is to be assigned (# 08 Yes branch), the command assigned to each partition is registered in the partition table as a command included in the subcommand menu for each partition (# 09), and this process is terminated. Since the partition table created by this command menu management setting process is used as the sub-command menu registration table in FIG. 1, the partition attribute data such as the identification name, reference coordinates, and partition size of each partition are assigned to the partition. The command is linked.

  When a subcommand menu registration table (partition table) is created, commands can be selected using this table. An example of the procedure of the drawing process in this CAD system is shown in the flowchart of FIG. Since it is necessary to select a command in order to perform some processing, first, command selection processing using a partition table, which will be described in detail later with reference to FIG. 8, is performed (# 30). When a command is selected, command work processing such as drawing, which is known per se, is performed based on the operation input information under the selected command (# 40). When one command work process is finished, it is determined whether or not the drawing operation is finished. If finished, this processing routine is finished (# 51 Yes branch), and if the drawing is still continued (# 51 No branch), the current situation It is determined whether to repeatedly use the command selected in (5) or select another command (# 52). If another command is selected (# 52 No branch), the process returns to step # 30 to perform command selection processing. If the currently selected command is repeatedly used (# 52 Yes branch), the process returns to step # 40 to perform command work processing.

  Next, command selection processing using a partition table will be described with reference to FIG. First, when the command selection process is started, a boundary line for clearly indicating the section is displayed in the drawing area 6a of the monitor screen (# 31). Next, the mouse position is acquired (# 32), and the section corresponding to the acquired mouse position is calculated using the position data and size data of the section registered in the section table (# 33). It is checked whether a command is assigned to a section corresponding to the mouse position (# 34). If no command is assigned (# 34 No branch), the command cannot be selected, and the process returns to step # 32. If one or more commands are assigned (# 34 Yes branch), display data of a subcommand menu including the command is generated (# 35) and displayed as a pop-up menu near the mouse position (# 36). That is, in this embodiment, a dynamic pop-up menu display method is employed in which when the mouse position reaches within a section, a subcommand menu consisting of commands assigned to the section is automatically displayed. Of course, you may adopt the method of displaying the subcommand menu for the first time when the mouse position reaches the section and there is an input operation event such as mouse click, and you can select it arbitrarily in the environment settings Also good.

  In the case where the command is not selected through the displayed subcommand menu and the user moves to the next section (# 37 No branch), the control flow takes steps after step # 32. When command selection is performed through the displayed subcommand menu (# 37 Yes branch), the selected command is transferred to the command processing unit 14 (# 38), and work processing by the selected command is performed. The boundary line is not displayed at this stage (# 39), and the current command selection processing routine is terminated.

  In the above-described command menu management procedure, the command assigned to the partition is the lowest command used directly, and the hierarchical structure is not considered in the command assigned to the partition. However, in the present invention, it is also possible to assign a hierarchically structured command to each partition. One example is a plurality of command menu assignment layers schematically shown in FIG. That is, one command menu assignment layer is a layer to which only a command for drawing a straight line is assigned, and another command menu assignment layer is a layer to which only a command for drawing a curve is assigned, thereby realizing a hierarchical structure of commands. Can do. At this time, in the command menu management setting process, a command higher in the hierarchy that should be a parent command is first selected, and then a lower command belonging to the command higher in the hierarchy is selected and assigned. FIG. 9 is a flowchart showing an example of a drawing process procedure that involves command selection using a subcommand menu registration table (partition table) created by adopting such a hierarchically structured command menu management. Yes. This flowchart is different from the flowchart of the drawing process using the command menu management which is not hierarchically structured in FIG. 7 in that the parent command, that is, the command higher in the hierarchy is selected before the command selection process in step # 30. Step (# 20) is interposed. In other words, before displaying the subcommand menu depending on the above-mentioned section, a higher command, for example, a parent command such as line drawing, curve drawing, or dimension line drawing is selected, and a lower command belonging to the selected parent command is selected. Only commands are displayed as subcommand menus for each section. As a result, even if there are a large number of commands to be used, it is possible to select them efficiently.

  This CAD system displays not only a function for displaying a subcommand menu depending on a section, but also a subcommand menu depending on a graphic object (element object) such as a straight line, a curve, or a character drawn in a drawing area. A function is also provided. That is, when the mouse position is close to or coincides with a predetermined position of an arbitrary element object, or when a mouse click (a kind of operation event) occurs at a predetermined position of an arbitrary element object, the element object A subcommand menu that depends on is displayed. When a specific command is selected through the subcommand menu, processing using that command can be executed. When such a command selection method is used, an assignment setting process for assigning a command to an element object in advance is necessary. FIG. 10 shows a dialog for such assignment setting processing. The dialog shown in FIG. 10 includes a dialog for setting command assignment to a partition shown in FIG. 5. In this dialog, a command is assigned to a specified partition while specifying the partition. Settings can be made. Therefore, in an embodiment having a function of displaying a subcommand menu depending on a graphic object, the dialog shown in FIG. 10 may be adopted instead of the dialog shown in FIG.

In the assignment setting dialog, the following display areas (1) to (7) are arranged.
(1) Element objects As objects to which commands are assigned, points, lines, circles, and the like, which are element objects drawn on the drawing screen, are listed.
(2) Singularity object A singularity drawn on the drawing screen is displayed as a list as an object to which a command is assigned. Singular points include end points, midpoints, center points, quadrant points, and intersections.
(3) Section object The set section is displayed as a list. This list-displayed partition is an object to which a command is assigned, and a command can be assigned to each partition in the same manner as the dialog in FIG. In this dialog, the control buttons for the sections in the list box are arranged. For example, the sections in the list box can be moved up and down with the up and down arrow buttons, and the section of the section is sorted with the replacement button. Can do.
(4) Element object classification method An area for setting a classification method for some items (line, circle, arc, ellipse, character, size character) in the element object, and for dividing the item into a plurality of items It is a setting area. This setting content differs for each element. For example, when the item is a straight line, invalidity / validity can be set for the straight line angle, and invalidity / two divisions / three divisions can be set for the straight line length. In the case of a circle, invalid, two divisions (horizontal), two divisions (vertical), and four divisions can be set. Furthermore, invalidity, two divisions, and three divisions can be set for arcs and elliptic arcs. Hereinafter, a case where the item is a circle will be described as an example.
Example:
1) Select circle from element object 2) Element object classification method area changes to display that can be selected from the following items,
Invalid, 2 division (horizontal), 2 division (vertical), 4 division 3) Select 2 division (horizontal) 4) The circle item in the element object area is automatically changed to circle (left) and circle (right) The
Thereby, different commands can be assigned to the two items (circle (left) and circle (right)), respectively. In actual operation, the command is switched when the left half of the circle element is specified with the mouse and when the right half is specified.
5) Singularity object classification method This is an area for setting whether to associate the item of a singularity object with the element type. When disabled, the singularity object items are (end point, midpoint, center point, 4 semicircle point, intersection point), and commands can be assigned to these items, but when enabled, as shown below Items are subdivided, and commands can be assigned to the subdivided items.
End point (straight line), end point (arc), end point (elliptical arc)
Midpoint (straight line), midpoint (arc)
Center point (circle), center point (arc), center point (ellipse), center point (elliptical arc)
4 semicircle point (circle), 4 semicircle point (arc), 4 semicircle point (ellipse), 4 semicircle point (elliptical arc)
Intersection (straight line), intersection (straight circle), intersection (straight arc), intersection (straight ellipse), intersection (straight ellipse)
Intersection (circle), intersection (circular arc), intersection (circle ellipse), intersection (circle ellipse)
Intersection (elliptical ellipse), intersection (elliptical ellipse).
6) Command list (refer to the left area in the center of FIG. 10)
Commands assigned to individual objects in the element object, singular point object, and division object, for example, straight line commands and circle commands are displayed in a list. A desired command can be introduced into the command list from the command string on the right side by a control button such as copy and paste arranged next to the control button.
7) Command name display check option 8) Other For example, when the command name display check option is turned ON, the command name is dynamically displayed in a dialog so that it can be determined which command is activated when the command is selected. Is done.

  In the dialog as shown in FIG. 10, when only one command is assigned to an object to which a command can be assigned, such as an element object or a singular point object, it is not necessary to select a command from the subcommand menu. Therefore, in actual use, when the mouse position is close to or coincides with the object, or when a mouse click (a kind of operation event) occurs at a predetermined position of any element object, the object Command selection is realized without displaying the only command assigned to. Therefore, it is possible to immediately execute processing such as drawing using the command. The case where only one command is given to each object in the partition object is the same as that shown in FIG. It should be noted that even if only one command is assigned to each of the element object and the singular point object, it is naturally possible to set to display the subcommand menu. In this case, the command name can be visually recognized through the subcommand menu.

  It is also possible to assign only one command to each of the element object and the singularity object. In this case, when the mouse position is close to or coincides with a predetermined position of an arbitrary element object, or when the mouse position is a mouse click (a kind of operation event) at a predetermined position of an arbitrary element object, The command assigned to the command menu is selected without displaying the command menu. Since the command is automatically selected in this way, the drawing operation is not disturbed by the command selection operation. Of course, in this case, the subcommand menu may be displayed before and after the command selection, and as a result, only the command name may be displayed.
