2. Description of the Related Art Generally, in a CAD system, a so-called menu system is used to input various commands instructing various operations and processes to the system when the system is used. .. In this menu system, a command menu consisting of an index indicating a large number of commands, for example, a command name or icon, is displayed on the screen of a display, and a desired cursor on the command menu is operated by a cursor operated by a pointing device such as a mouse. A desired command is input by instructing the index corresponding to the command.

Many of the commands instructing various operations and processes in the CAD system may be accompanied by command data such as parameters. As such command data, for example, in many commands such as “line” command and “circle” command in “drawing” command of “drawing creation” command,
"Pen number", "Color", "Pitch", "Line type",
"Text size", "Dimension text size", "Drawing scale",
There are "radius of circle" and "diameter of circle". In the conventional menu system, a part common to many commands among these command data is always fixedly displayed as part of the screen as information indicating the setting state. In some cases, the setting state could be selected by pointing with the cursor. However, the place where these command data are displayed is a narrow part after securing the drawing screen, command menu, etc., for example, "drawing scale", "angle condition value", "circle radius", Items such as "diameter of circle" that require numerical input, items for complicated or detailed setting, and items specific to a specific command were not displayed.

If an item involving numerical input, an item for complicated or detailed setting, and an item specific to a specific command are set or changed, the "initial setting" command on the command menu is used. Or it was set in the menu hierarchy related to the execution of individual commands. Generally, the command menu has a hierarchical structure, and in the normal case, the “initial setting” command is located in a relatively higher hierarchy, and by executing this “initial setting” command, a menu for initial setting, etc. Is displayed. Also, when setting in the menu hierarchy related to the execution of individual commands, a menu for specifying / changing command data is displayed as one step in the execution process of each command when executing each command. Specify and change the command data with. In addition, as the item for complicated or detailed setting, an item group in which any one of a plurality of items should be selected alternatively,
That is, it is possible to select a group of items for which duplicate selection is not allowed or one or more arbitrary items of a plurality of items.
It includes an item group that can be selected at any time, that is, an item group that allows duplicate selection. When selecting these item groups from the menu, etc., the operator determines the content of each item individually and specifies it, and if incorrect specification is made, the system gives a warning. Has been.

[0005]

As described above, in the menu system used in the conventional CAD system, the operator is familiar with the contents and conditions of each item for complicated or detailed setting items. It is necessary to make a distinction, and designation of such an item is troublesome for the operator and causes a complicated operation of the system. The present invention has been made in view of such circumstances, and an object of the present invention is to provide a command input method and apparatus that can effectively simplify an operator's operation for setting various items in a CAD system.

That is, the command data panel displayed on the display 3 via the command display control unit 11, the data display control unit 13, and the display control unit 5 is in the normal mode when the cursor is outside the command data display area. It is displayed, and when the cursor is in the command data display area, it is displayed in the enlarged mode. In the normal mode, the command data panel displays information such as command data in a relatively narrow command data display area to the extent that the current command data setting status can be known.In the expanded mode, the command data display area is expanded. Information necessary for setting command data and the like and information such as the current setting state of command data and the like are displayed in a command data display area wider than in the normal mode. The command display control unit 11 and the data display control unit 13 display the command data panel in the enlargement mode, and the data information group that should be set only selectively among the displayed command data and the data information group that can be set redundantly. In order to clearly distinguish between and by the display arrangement direction, the data information group that should be set only alternatively is arranged in the horizontal (horizontal) direction, and the data information group that can be set redundantly is set only in the alternative. The data information groups to be arranged are arranged in, for example, a vertical (vertical) direction different from the arrangement direction (see FIG. 6, details will be described later).

Next, the operation particularly relating to command input in the CAD system having such a configuration will be described with reference to FIGS.
This will be described in detail with reference to the flowchart shown in FIG. The process shown in FIG. 2 is started when the CAD system is started and is constantly operating during the normal drawing or editing operation in the CAD system. The process shown in FIG. 3 is the normal drawing by the routine in FIG. 2 in the CAD system. Alternatively, it is a subroutine that is started as an interrupt process when the cursor enters the command data area during the editing operation. First, when the system is activated, the display control unit 5, the cursor display control unit 6, and the command display control unit 11 display a command menu, a command data panel, and a cursor on the screen of the display 3 (step S1). At this time, the command menu is display 3
The command data panel is displayed in the command data display area on the screen of the display 3. In the normal case, the command display area and the command data display area are arranged in the peripheral portion such as the side edge on the screen of the display 3, and the wide central portion of the screen of the display 3 is used for original drawing, drawing editing, etc. It can be so.

Monitoring of the cursor position by the cursor position identification unit 15 is started when the command menu, the command data panel and the cursor are displayed on the screen of the display 3.
This routine is continuously performed while the routine is executed (step S2). The monitoring of the cursor position in step S2 is for detecting that the cursor has entered the command data display area. Immediately after the cursor enters the command data display area, the interrupt subroutine shown in FIG. It Cursor position identification unit 1
When the operator operates the input device 4 to input a command while the cursor position is being monitored by 5 (step S3), the command is executed (step S4).

Specifically, the operator inputs the command in step S3 via the input device 4 to the display 3
By moving the cursor on the screen of the display 3, selecting an index of an arbitrary command on the command menu of the screen of the display 3 with the cursor, and performing a predetermined operation for executing the command, the command input processing unit 12 This is performed by discriminating and detecting a command and giving it to the CAD processing unit 2. Further, the execution of the command in step S4 is performed by the CAD processing unit 2 according to the given command.
Is performed by operating in a predetermined manner. The input of the command in step S3 and the execution of the command in step S4 are repeated until the end command is executed as the execution of the command in step S4.

Next, the interrupt processing of FIG. 3 which is activated when it is detected that the cursor has entered the command data display area during the execution of the processing of FIG. When the interrupt process is activated, the enlarged display control unit 16 operates to operate the command display control unit 11 and the data display control unit 1.
3 is controlled, and the display mode of the command data panel is changed to the enlargement mode (step S11). In the expanded mode, the command data display area of the command data panel is expanded to a wider area than in the normal mode, and in this expanded command data display area, the information necessary for setting command data and the current setting of command data are set. Display information such as status. In this enlargement mode, in order to clearly distinguish the data information group that should be set only selectively and the data information group that can be set redundantly among the displayed command data by the display arrangement direction, only the alternative The data information group to be set is, for example, arranged in the horizontal direction, and the data information group that can be set redundantly is arranged, for example, in the vertical direction, which is different from the arrangement direction of the data information group to be set alternatively (see FIG. 6).

In step S11, as soon as the display mode of the command data panel is changed to the enlargement mode, the cursor position identification section 15 starts to monitor the cursor position for the enlarged command data display area. This routine is continuously performed while the routine of FIG. 3 is being executed (step S12). The monitoring of the cursor position in step S12 is for detecting that the cursor leaves the enlarged command data area. When the cursor leaves the enlarged command data area, the interrupt processing shown in FIG. The subroutine 3 is stopped and the process returns to the routine shown in FIG.

Next, when the operator operates the input device 4 to wait for a command data setting / change input, and a command data setting / change input is made (step S
13), the command data setting / changing process is executed (step S14). To set / change the command data in step S13, specifically, the operator moves the cursor on the screen of the display 3 via the input device 4 to display arbitrary information on the command data panel of the screen of the display 3. By selecting with the cursor and performing a predetermined operation for setting / changing the command data, the data setting processing unit 14 discriminates and detects the setting / change contents of the command data, and the CAD processing unit 2 and the data display control. It is performed by giving it to the part 13. Further, the command data setting / changing process of step S14 is specifically performed by the CAD processing unit 2 and the data display control unit 13 operating in a predetermined manner according to the given setting / changing contents of the command data. ..

Setting of command data in step S13
In the change input and the execution of the command data setting / changing process in step S14, it is detected by the cursor position identifying unit 15 that the cursor has left the enlarged command data area, and the interrupt process in FIG. Is repeated until is stopped. During execution of the subroutine shown in FIG. 3, when the cursor position identification unit 15 detects that the cursor has moved out of the enlarged command data area, the subroutine shown in FIG. 4 is immediately activated to operate the command data of the subroutine shown in FIG. The processing related to the process is terminated (step S21), the command display control unit 11 and the data display control unit 13 are controlled via the enlargement display control unit 16, and the display mode of the command data panel is returned from the enlargement mode to the normal mode. The data area is reduced / restored to the state before enlargement (step S22), and the process returns to the routine of FIG.

Here, an example of a specific operation in this system will be described in detail. First, in the CAD system, menus and the like on the screen when the system is operating are basically divided into areas and displayed as shown in FIG. That is, the top level menu M is displayed on the left edge of the screen.
1 is displayed, and the pick menu M2, the go menu M3, and the command data panel D are displayed on the right side in order from the top.
P is displayed. The area in which the top level menu M1, the pick menu M2, and the go menu M3 are displayed is the command display area, and the area in which the command data panel DP is displayed is the command data display area.

Immediately after the system is started, the display is at the highest level, and the top level menu M1 displays the highest level command menu including commands such as "drawing creation" and "drawing management". When the "Drawing" command is instructed in the menu M1, the top level menu M1 and the pick menu M
"Drawing creation" is displayed on the command line CL, which is a column located above 2, and a drawing creation menu consisting of commands such as "drawing" and "annotation" in the next layer is displayed on the pick menu M2. .. If, for example, the "Draw" command is selected in this drawing creation menu, the command line CL
In the pick menu M2, a drawing menu consisting of commands such as "line", "circle", "ellipse", and "free curve" in the next hierarchy is displayed in place of the drawing creation menu. It

Furthermore, in this drawing menu, for example, "line"
When the command is selected, as shown in Figure 5,
"Line" is displayed on the command line CL, and the pick menu M2 has "Continuous", "2 points", and "Horizontal" in the next layer.
A line menu consisting of commands such as is displayed instead of the drawing menu. With such a change in the menu content of the pick menu M2, the content of the go menu M3 including commands such as “stop”, “execute”, and “move” also changes to the content of the pick menu M2 displayed at that time. It changes according to the one. At this time, on the command data panel DP, as shown in FIG. 5, "automatic recognition" indicating the state of point selection, "1 white" indicating the selection state of the pen number,
Each display of "5 light blue" which shows the selection state of color, "standard" which shows the selection state of pitch and "-" which shows the selection state of line type, and a toggle switch which specifies the drawing method of the line (for each instruction Each display of "■ single", "□ reference movement", "□ reference fixed" and "□ virtual element" showing the switch function whose state changes alternately is displayed.

Note that "automatic recognition" means that point selection is performed by automatic recognition, "1 white" means that the white pen with pen number 1 is selected, and "5 light blue" means that the selected pen number 1 is selected. The line drawn with the white pen is displayed in light blue, "Standard" means that the standard pitch is selected as the pitch of the broken line, and "-" means that the line type is selected. I mean. Further, “■” or “□” at the head of the toggle switch indicates that the toggle switch is on, and “□” indicates that the toggle switch is off. That is,
"■ Single" means that the single mode is selected as the line drawing mode, "□ Reference movement" means that the reference movement mode is not selected as the line drawing mode, and "□
"Fixed reference" means that the fixed reference mode is not selected as the line drawing mode, and "□ virtual element" means that the virtual element mode for drawing the draft line is not selected as the line drawing mode. ing.

In the state of FIG. 5, the cursor CS is outside the command data panel DP, that is, outside the command data area,
For example, it shows the state when in the drawing area. When the contents of the command data panel DP are to be changed in the state of FIG. 5, if the cursor CS is moved to the command data panel DP, that is, within the command data area,
Immediately, as shown in FIG. 6, the command data area is enlarged and the command data panel DPe is displayed in the enlargement mode. Command data panel DP in expanded mode
As for the display contents of e, in the setting state similar to that of FIG. 5, as shown in FIG. 6, “point selection automatic recognition” indicating the state of point selection and “pen number 1
“White”, “Color 5 light blue”, which indicates the selected color,
Each display of "pitch standard" showing the selected state of the pitch and "line type-" showing the selected state of the line type is detailed. Further, each of "angle condition value" and "layer" is displayed.

Regarding the toggle switch for designating the line drawing method, "■ single", "□ reference movement",
In addition to the display of “□ fixed reference” and “□ virtual element”, “□ symmetry” indicating the selected state of the symmetrical drawing mode is displayed. Here, the three toggle switches, "single", "reference movement" and "fixed reference", are toggle switches that cannot be set redundantly and one of them must be set to on only selectively. Therefore, in this case, as shown in the drawing, they are arranged in one row in the horizontal direction, that is, in the horizontal direction of the screen. These "single", "reference movement" and "reference fixed" toggle switches will force you to set any one of the three to ON, if any have been set to ON until then. Is turned off (the function of turning off a toggle switch other than the selected one of the toggle switch groups that is selected alternatively may be enabled / disabled arbitrarily). It should be noted that such an arrangement of toggle switches can be used also in the case where it can be alternatively set to on and all can be set to off. Since the two toggle switches of "virtual element" and "symmetrical" are toggle switches that can be set to overlap with each other, in this case, they are arranged in the vertical direction of the screen, that is, in the vertical direction, as illustrated. These "virtual element" and "symmetrical" two toggle switches can be turned on in part or either, or in all or both, or all or both. You can also In addition, these "virtual element" and "symmetrical" two toggle switches and the "single",
Overlapping settings are also possible with the "reference movement" and "reference fixing" toggle switch groups, and the positional relationship in which these are also arranged in the vertical direction means that there is a conflict between the possibility of overlapping setting and the corresponding relationship between the positional relationships. do not do.

In this state, the setting state is changed by selecting the item to be changed in the command data panel DPe with the cursor CS. Specifically, the setting state of the command data panel DPe is changed as follows. With respect to the pen number, color, pitch and line type, the setting contents are sequentially changed each time an item is designated. The “single”, “reference movement”, “fixed reference”, “virtual element” and “symmetry” toggle switches are also turned on / off each time an item is designated. As described above, for each of the “single”, “reference movement”, and “fixed reference” toggle switches, one of them is designated to be turned on, and the “virtual element” and the “symmetry element” are set. One or both of the toggle switches of “” are arbitrarily designated. Further, regarding the “angle condition value” and the “layer”, when the respective items are selected, the angle condition value input screen and the layer setting screen are displayed, and the respective settings can be performed.

When the setting contents of the command data panel DPe are changed, the cursor CS is moved outside the command data panel DPe, that is, outside the command data area.
For example, by moving to the drawing area, the command data area becomes the normal mode and returns to the command data panel DP in the original display state. Switching between the command data panel DP and the command data panel DPe, that is, switching between the normal mode and the enlargement mode is performed by assigning keys on the keyboard, for example, an escape key, a specific function key (a shift function key such as a programmable function key or a control key + It can also be done by a specific key). In this case, operability is good if the toggle operation is performed by alternately repeating the normal mode and the enlargement mode with the same key operation.

As described above, when the information such as the command data is changed, the command data panel DPe in the enlarged mode is displayed instead of the command data panel DP in the normal mode, so that the setting / change of the command data including the numerical value input is performed. Can also be done easily. In addition, the command data panel DPe in the enlarged mode can display the item contents of the command data, a list of selectable data, and the like as needed, so that the setting / changing operation of the command data can be performed extremely easily. it can. In addition, the size of the command data panel DPe in the enlargement mode is not limited to simply extending the command data area in the normal mode to the right side of the drawing to widen the width according to the contents to be displayed and set.
The command data area may be expanded in the vertical direction of the screen. In that case, the command data panel DPe that covers the pick menu M2, the go menu M3, and the drawing area with the command data area at the maximum can be used.

Further, in FIG. 5 and FIG. 6, "drawing creation" is performed.
-The "Drawing"-"Line" command was selected, but when another command is selected,
The contents of the command data panel DP are different from those in FIGS. FIG. 7 shows an example of the command data panel DPe ′ in the enlargement mode used for the surface command. In this case, the command data panel DPe ′
As shown in Fig. 5, "■ single", "□ reference movement",
There are no "□ reference fixed" and "□ symmetrical" toggle switches, instead there are "□ color", "□ type", and "□ boundary line" toggle switches. "□ color" is a toggle switch for setting the color to fill the surface, and when this toggle switch is turned on, the pick menu M2
A menu for selecting a color is displayed (see FIG. 6), and the color can be selected. The "□ type" is a toggle switch for setting the hatching pattern of the surface. When this toggle switch is turned on, a menu for selecting the hatching pattern is displayed in the pick menu M2 (see Fig. 6) and the hatching pattern is displayed. You will be able to make a choice. 「□
"Boundary" is a toggle switch for setting whether to draw the boundary of the surface. When it is on, the boundary of the surface is drawn, and when it is off, the boundary of the surface is not drawn.

Since the toggle switch groups of "□ color", "□ type", "□ boundary line" and "□ virtual element" are toggle switch groups capable of overlapping selection, in this case, as shown in FIG. They are arranged vertically or vertically on the screen. Some of these toggle switches can be turned on, all can be turned on, and all can be turned off. In the above description, the data information groups that should be set only alternatively are arranged in the horizontal direction, and the data information groups that can be set redundantly are arranged in the vertical direction. For example, the data information groups to be set may be arranged in the vertical direction, and the data information groups that can be set overlapping may be arranged in the horizontal direction. The data information groups which are arranged in a predetermined direction and which can be set overlappingly may be arranged in a second predetermined direction which is different from the first predetermined direction. Further, such an array is applied not only to information such as command data of the command data panel but also to various information that can be selectively and redundantly selected in relation to a command, and is also selectively applicable to them. It is also possible to clarify the distinction between the information group that should be set only in the above and the information group that can be set redundantly to facilitate the operation of the operator.
