Description

Detailed Description of the Invention

[0001]

The present invention relates to CAD (computer-aid).
ed design) system, and more particularly, to a command input method and apparatus for inputting commands instructing various operations and processes in a CAD system.

[0002]

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 "circle diameter" that require numerical input, items that require complicated settings, and items specific to a particular command have not been displayed.

When setting or changing items such as those that require numeric input, items that require complicated settings, and items that are specific to a particular command, the "initial setting" command on the command menu or the individual It was set in the menu hierarchy related to the execution of the command. 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.

[0005]

As described above, in the menu system used in the conventional CAD system, command data associated with a command is designated and
When changing, except for a small part common to each command, prepare a menu etc. for specifying / changing command data as one step of the execution process of each command when executing each command. Specify or change such command data by placing it or by displaying a menu for specifying or changing command data by using the "Initialize" command that is prepared relatively higher in the menu hierarchy. I was doing.

Therefore, when the command data is specified / changed in the menu hierarchy in the command execution process, the command data associated with the command must be specified / changed each time the command is executed. In addition, when command data is specified / changed by a separate "initialization" command, the "initialization" command must be activated to specify / change the command data prior to executing the desired command. did not become.
Therefore, the operation for designating / changing the command data makes the operation of executing the original command more complicated than necessary, and makes the operation of the system more complicated.

In particular, when it is desired to specify / change command data during execution of the original command, in the former case (that is, when command data is specified / changed in the menu hierarchy of the command execution process), command execution is performed. Must be stopped, the command data can be specified / changed, the menu must be displayed again, the command data can be specified / changed, and then the menu must be advanced again to execute the command. In the case of using a separate “initial setting” command), the command being executed must be canceled once and the “initial setting” command must be executed to specify / change the command data.

The present invention has been made in view of the above circumstances, and it is possible to arbitrarily and easily specify and change command data during the operation of the CAD system, and to significantly simplify the operation of the operator. An object is to provide an input method and device.

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 from the time when the command menu, the command data panel and the cursor are displayed on the screen of the display 3, and the monitoring of the cursor position is performed by this FIG.
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 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. Immediately after the display mode of the command data panel is changed to the enlargement mode in step S11, the cursor position identification unit 15 starts monitoring the cursor position for the enlarged command data display area,
This cursor position monitoring 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. .. Step S13
In the setting / changing input of command data and execution of the setting / changing process of command data in step S14, the cursor position identification unit 15 detects that the cursor has left the enlarged command data area, and the interruption of FIG. The process is repeated until the subroutine of FIG. 3 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 point selection by automatic recognition, "1 white" means that the white pen with pen number 1 is selected, and "5 light blue" means selected pen number 1 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. For the toggle switch that specifies the line drawing method, in addition to the display of "■ Single", "□ reference movement", "□ reference fixation" and "□ virtual element", the symmetrical drawing mode selection status “□ Symmetrical” is displayed.

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. For each of the "single", "reference movement", and "fixed reference" toggle switches, one of them is designated to be turned on, and for the "virtual element" and "symmetric" toggle switches. , Either one or both are arbitrarily designated. Therefore, "single", "reference movement", and "reference fixation"
With regard to the above, when the one which is not turned on at that time is turned on, the one which is turned on until then may be automatically turned off. 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. Further, when the setting contents of the command data panel DPe are changed, the cursor CS is moved to the outside of the command data panel DPe, that is, to the outside of the command data area, for example, the drawing area, so that the command data area becomes the normal mode. The display returns to the command data panel DP in the display state of. 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. 7 and 8 show a normal mode command data panel DP 'and an expanded mode command data panel DP commonly used for many general commands.
This is an example of e '. In this case, the command data panels DP ′ and DPe ′ do not have the toggle switch group as shown in FIG. 5, and instead, “scale 1.
It includes the items "0" or "Drawing scale 1.00000" and the items "Layer", "Screen display" and "Cursor". Select "Layer" to display the layer menu to select the layer to handle, select "Screen display" to display the screen display mode setting menu to set the screen display mode such as screen display color, and When "Cursor" is selected, the setting screen for setting / changing the cursor size is displayed.
