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.

Here, an example of the command menu system in the conventional CAD system will be specifically described. FIG. 10 shows a part of the menu system of the command menu. The command group G1 is composed of "drawing creation", "drawing management", "design", "initial setting", "tablet", "NC link", etc. for the basic work of the system and constitutes the highest-level menu. To do. When the operator selects "Drawing" from the menu of this command group G1, the command group G2 that constitutes the next menu is "Drawing", "Annotation", "Figure allocation", "Relational definition", "Prop". Form "etc. When "Draw" is selected from the menu of this command group G2, the command group G3 that constitutes the next menu is "Line", "Circle", "Ellipse", "Free curve", "Point", "Rectangle". , "Polygon", "Surface", "Symbol", "Hole symbol", "Slot symbol",
It consists of "traces". Also, the command group G2
The command group G4 that constitutes the next menu when "Annotation" is selected in the menu is "Character", "Dimension", "Leader", "Calculation", "Symbol", "Balloon", "Parts". Table ”etc. This command group G
The command group G5 that constitutes the next menu when "Dimension" is selected from the menu of No. 4 is "Standard", "One arrow", "Angle", "Radius", "Diameter", "Progressive", " It consists of "coordinates", "arc length", "chamfer", "cross section", etc.

In such a menu system, a lower-order command menu related to the "line" command in the conventional system will be described with reference to FIG. When "Drawing"-"Drawing" is sequentially selected, the menu M31 of the command group G3 on the screen and the menu M32 of the command group G6 such as "Cancel", "Element", and "Virtual element" related thereto are displayed. .. In this state, if you select the "Line" command, "Automatic recognition" for selecting the specified point, "Existing point", "Arbitrary point", "Grid", "Final point", "Intersection point", " A point selection menu M33 including a command group G7 such as "point on element", "middle point", "absolute coordinate", "relative coordinate", "angle and distance", and "stop", "execute",
The menu M34 of the command group G8 such as "move", "initial value", "angle condition", "filter", etc. is displayed instead of the menus M31 and M32, and the instruction of the first point is prompted. If you specify the first point, menu M33
And menus M35 and M36 that are exactly the same as M34
Is displayed and you are prompted to specify the next point. When a line is continuously drawn (that is, made into a polygonal line shape) by sequentially and sequentially designating points, a menu exactly the same as the menus M35 and M36 is repeatedly displayed.

[0007] In the state where the menus M35 and M36 are displayed, if the point instruction is canceled, the menu M36
When "Cancel" is selected in, the menus M33 and M34 that are exactly the same are displayed, and the previous point is entered. When "Cancel" is selected in the menu M34, menus M31 and M3 related to the command group G3 for drawing are selected.
2 is displayed, and the command selection such as the “line” command for drawing can be performed.

[0008]

As described above, in the menu system used in the conventional CAD system, the point selection menu is selected, for example, at the last step in the command hierarchy of commands such as "Draw"-"Line". M35 etc. were displayed. In such a point selection menu, the frequently used "automatic recognition" is displayed at the top of the menu,
Immediately after the point selection menu is displayed, the cursor can be positioned at the highest level "automatic recognition" to simplify the operation. However, for example, the contents of the menu at a higher hierarchy than the point selection menu When it was desired to select, it was necessary to perform a "stop" operation each time.

For example, in FIG. 11, when the "line" command is used for drawing and it is desired to move to drawing a circle,
The "circle" command is selected in the menu M31, but since the point selection menu M33 is displayed during the drawing of the line, if the "stop" operation is not performed once, the menu M3 is selected.
1 cannot be displayed. Such a situation can occur quite frequently in drawing or the like, but the conventional system requires the complicated operation as described above.

When command data associated with a command is specified or changed, the command is executed as one step in the execution process of the command at the time of execution of each command, except for a small part common to each command. Whether to prepare a menu etc. for specifying / changing data, or to display a menu for specifying / changing command data by using the "Initialize" command, which is separately prepared relatively higher in the menu hierarchy. Then, such command data is specified and changed.

Therefore, when the command data is specified / changed in the menu hierarchy in the command execution process, the command data accompanying 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 the command data during the execution of the original command, the former (that is, when the command data is specified / changed in the menu hierarchy of the command execution process) executes the command. 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 easily and arbitrarily specify / change command data including specification / change of a point selection method during operation of a CAD system.
An object of the present invention is to provide a command input method and device that can be changed and can easily switch commands, and can significantly simplify the operation of the operator.

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. Regarding the point selection, when the item "Point selection" in the command data panel DPe is designated by the cursor CS, as shown in FIG. 7, the pick menu M2 is replaced with "automatic recognition" and "existing point" instead of the line menu. ",
"Arbitrary point", "Grid", "Final point", "Intersection", "Point on element", "Middle point", "Absolute coordinate", "Relative coordinate", "Angle and distance", etc. A point selection menu of the type of the selection method is displayed, and the display contents of the go menu M3 are accordingly commands such as “stop” and “execute”. The point selection method can be selected by operating the cursor in this state to select and instruct an arbitrary item in the point selection menu. With respect to the pen number, color, pitch and line type, the setting contents are sequentially changed each time an item is designated. "Single", "reference movement",
Each of the “fixed reference”, “virtual element” and “symmetrical” toggle switches is also turned on / off each time an item is designated. For each of the "single", "reference movement", and "fixed reference" toggle switches, one of these is designated to be turned on,
One or both of the "virtual element" and "symmetrical" toggle switches are arbitrarily designated. Therefore, regarding “single”, “reference movement”, and “reference fixation”, when the one that is not on at that time is turned on, the one that was on until then is automatically turned off. You can 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. In addition, command data panel D
Switching between P and the command data panel DPe, that is, switching between the normal mode and the enlargement mode is performed by the assignment key of the keyboard,
For example, an escape key, a specific function key (a programmable function key, a shift function key such as a control key, and a specific key) can be used. 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.

Regarding point selection, point selection is prepared as one item of the command data panels DP and DPe, and the point selection menu is displayed by instructing the item. Therefore, for example, only when it becomes necessary to change the point selection method, the command data panel DPe
By pointing to the point selection item, the point selection menu is displayed and the point selection method can be changed. For this reason, the point selection menu can be excluded from the command hierarchy, and the command data panel that includes point selection is always displayed during the processing of "line" commands, etc., so you can select points at a more flexible timing than before. It can be carried out. In this way, by excluding the point selection menu from the command hierarchy, for example, the command hierarchy of the "line" command becomes shallower.
It is possible to display a line menu consisting of commands such as "continuous", "two points", "horizontal", and "vertical" for designating a line instruction method that did not exist in the past. Operability is improved compared to the command hierarchy of. "line"
The line menu is always displayed during the processing of the command, and if the cancel operation is performed once in this state, the contents of the pick menu M2 are returned to the drawing menu at any time. Therefore, the command canceling operation is also very simple without the need for complicated repetition of the canceling operation.

Note that the "continuous" command is continuous (that is, in a polygonal line) by continuously specifying points.
This is for designating the method of drawing a line in which a group of straight lines is drawn one by one. Conventionally, only this mode was basically available, and this mode was automatically set when the "line" command was selected. The "two-point" command designates two points on a straight line and specifies a straight line passing through those two points. These "continuous" and "two point" commands are used for both elements (ie real elements) and virtual elements, while "horizontal" and "vertical" commands are used only for virtual elements. The "horizontal" command designates a horizontal line on the screen passing through the point by one point designation. The "vertical" command designates a line in the vertical direction on the screen which passes through the point by one point designation.
That is, after setting a draft line as a virtual element in this way, "continuous" or "two points" are set on the draft line.
Specify the (real) element with the command.

Further, 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 in the drawing to expand the lateral width, depending on the contents to be displayed and set. The 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. Also, 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.

8 and 9 show a normal mode command data panel DP 'and an expansion 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.
