Abstract

PURPOSE:To rapidly and correctly change over a command by the use of an already displayed graphic or the like by designating a desired one of the already displayed graphic, character, symbol and selecting the command for displaying the graphic or the like. CONSTITUTION:An user designates the graphic of the same type as the graphic desired to draw next from the graphics or the like already displayed on a display 36 by the use of a mouse 20. (for instance, a circular arc) a CPU28 retrieves the data base 31 of a main memory device 30 based on the designated input from the mouse 20 and detects the data of the circular arc 40. Then, the CPU28 discriminates that the detected data is the data of the graphic or the data of the character, since this is the data of the graphic relating to the circular arc 40, it reads an application program for forming the circular arc from an external memory device 32 so as to have a command mode for plotting the circular arc and stores in the prescribed area in the main memory device 30.

Description

Detailed Description of the Invention 3. Detailed Description of the Invention [Field of Industrial Application] This invention relates to a graphic data processing apparatus using a computer, which is generally referred to as a CAD system or CAD/C△~1 system. Regarding improvements.

[Prior Art] FIG. 4 is a diagram showing an example of a display screen of a conventional CAD/CAM system. Referring to FIG. 11. For example, a menu area 12 is provided in the bottom column of the display screen 10. In the menu area 12, for example, A maximum of 10 commands can be displayed.The user selects the desired command if there is one among the commands displayed in menu IJ! , search for the desired command while turning the displayed pages, and select the command.

To give a concrete example, if you want to draw a "circle",
You can operate as follows. First, menu j or 12
To, [■ Ray V ■ Frame change ■ L1 semi-setting ■ Standard cancellation ■ Zoom ■
The command Plot ■ Next item ■ Menu j is displayed. The user specifies "Drawing" using a pointing device such as a mouse, light pen, or cursor. Depending on the menu area 1
In 2, the following command appears: [■Line segment■Continuous line■Auxiliary line■Circle■Cross■Circular arc■FI4 shape■Spline■Next item [stock] Epigastric''. Therefore, if "0 yen" is specified with the pointing device, the command save becomes a mode for drawing a circle, and a program for drawing a circle +i/i< is read out.

However, if you want to draw "letters" in the room you are using, specify "■Next item" of the command that appears in the menu area 12, and while manipulating the page, the desired command, that is, the command "letters" will appear. You can repeat the operation until.

After setting the desired command bead, for example, the 7th bead of the command “circle”, select the figure display area 1/ of the display screen 10.
Use the pointing device to specify where you want the figure on l to be j1δ. Taking the case of a "circle" as an example, there are various methods. For example, specify the center point (center coordinates) and the size of the radius using a boining device. This will draw a circle. In addition, the attributes of the drawn circle, such as whether the circle is displayed as a solid line, a dotted line, a dashed line, the color of the line, the color of the line, and the thickness of the line, are displayed in the attribute display. Displayed in area 16. It is also possible to change the attributes of the drawn figures.

[Problems to be Solved by the Invention] Incidentally, as the performance of the CAD/CAM system increases, the number of commands for data processing increases. Therefore, when displaying commands using the menu area 12, which can display less than 10 types of commands at a time, the command display page spans multiple pages, especially several tens of pages, and in order to find the desired command, pointing The number of device operations increases, which takes time and effort.

Further, if the user roughly memorizes which commands exist on which pages in advance, the command search process can be performed relatively smoothly, but this requires considerable skill in using the device.

On the other hand, instead of displaying commands in the menu area 12, there is also a system in which the commands are sent from the tablet 18 (see FIG. 4). However, with the command input method using the tablet 18, it is difficult to find a desired command among all the commands displayed on the tablet, for example, 100g1 or more commands, and it takes time to select a command. There are drawbacks such as.

Furthermore, the method using the menu area 12 has R3 and the method using the b1 tablet 16.
The meaning of a command is often expressed by a very short name. For example, the command "Draw a straight line" is rLNJ
The -1 cloak that says "Draw a U circle" is rcRJ.
This is how it is expressed. Therefore, if commands are displayed using such abbreviations, it is necessary to understand the meaning of the :command.

Therefore, the present invention has been made in order to solve the problems of the conventional devices as described above. The purpose of the present invention is to provide a graphic editor with an improved method of specifying the -1 mantle when switching.

[1ζth Means for Solving the Problem] The graphic data processing device according to the present invention is capable of processing a graphic data that is already displayed. , symbols, etc. in the graphic data is specified by the display specifying means, the content of the specified display is detected from the storage means, and the command is switched based on the detected content. /It's my child's.

[Operation] By specifying a desired character or symbol of a figure that is already displayed, a command to display the specified figure, etc. is selected, and the corresponding program is read out. 5. Therefore, there is no need to select a desired command from among a large number of commands, and commands can be selected using the already displayed graphics, allowing quick and accurate command switching.

[Embodiment] Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a block diagram showing the overall schematic structure of an embodiment of the present invention. Signals input from one keyboard and a mouse 20, which is an example of a pointing device, are sent from an input circuit 24 to a back 27 circuit 26 to a C.
Given to P LJ 28. CI) U 28 is the control center of this device, and responds to input signals and performs data processing operations based on the main memory 30, etc. Specifically, based on the command switching signals from the keyboard 19J3 and the mouse 20, the application program n stored in the external storage device (for example) 32 (for example, a double disk, a solid-state memory device such as a ROM, a cassette tape, etc.)
A program corresponding to the command specified from γ is read out and stored in a predetermined area of the main storage device 30. When a signal specifying a display area is given from the keyboard 19 or the mouse 20, the CPU 28 processes data based on an application program or the like, and provides display data to the video RAM 3/I. The data stored in the video RAM 34 is displayed on the display 36. Further, the display data processed by the CI) U 28 is stored in the database 31 of the main storage device 30.

FIG. 2 is an illustrative diagram showing the relationship between the graphic J3 and characters displayed on the screen of the display 36 and the contents stored in the database 31 of the main storage device 30. Referring to FIG. 2, on the display 36, as shown,
A solid straight line 38, a dotted arc 40, and a character [0M
Consider a case where 11ONJ42 is displayed. In this case, the database 31 contains il! Data relating to line 38, data relating to arc 40 and data relating to character 42 are each stored. Specifically, data regarding the straight line 38 is as follows: [Start point coordinates: X 1 , I , End point coordinates: Xz, Y
2. Data such as "line type: solid line, line thickness: 0.6 mm, color: blue", etc., are "center coordinates" 3* as data for arc 40.
2, radius; r5, starting point angle 202, ending point angle: 02
, line type: broken line, line thickness: Q, 4n+m, color: green :1/2, tilt angle: θ2, character type: English, character content: OMRON, color: white], etc. are stored.

Figure 3 shows the actual results of this invention! Flowchart 17 represents the operation when the graphic data processing device according to the example executes a process of switching commands using already displayed figures (hereinafter referred to as "graphic command process"). be. Next, the graphic command processing operation will be explained in accordance with the flow shown in FIG. 3 and with reference to FIGS. 1 and 2 as necessary.

Depending on the use, a specific key on the keyboard 19, such as r
When the QJ key is pressed, the CPU 28
When human power is detected, the device will display a graphic = 7 mand 7-
It becomes de.

In graphics command mode, CPIJ 28 has signal input from mouse 20. The user must use the display
From among the figures already displayed on the screen 36, use the mouse 20 to specify the same type of figure as the figure you wish to draw next. For example, referring to FIG. 2, if the next figure the user wants to display is a circular arc, he or she would specify any part of the circular arc 40 using the mouse 20.

Based on the specified input from the mouse 20, the CPU 28 searches the database 31 in the main storage device 30. and,
Display data including the point coordinates specified by the mouse 20 is detected. In this case, data on the arc 40 is detected from the database 31.

If the corresponding data is not recorded in the database 31, a non-displayed point will be specified with the mouse 20, and in that case, error processing will be performed.

When display data including a point specified by the mouse 20 is detected, CI) U 28 displays a shape related to the detected display data, in this case an arc/IO, in a specific color,
For example, it is illuminated in red so that the user can recognize that the data of the arc 40 has been detected.

Next, the CPU 28 determines whether the detected data is graphic data or character data. In this case, the detected data is graphic data related to the arc 40, so CI) U
28 reads out an application program for creating an arc from the application program 8Y in the external storage device 632 so as to enter a command mode for drawing the figure, that is, an arc, and stores it in the main storage device ff13.
0 in a predetermined area.

Therefore, the device is in a state where it can create a circular arc.

When a character is designated with the mouse 20, for example, when the character rOMRONJ 42 in FIG. 2 is designated, the CPtJ 28 determines the character content and determines whether the character content is a predetermined character. . , characters with predetermined contents are TatoeL;r, rcIRcL
EJ rLINEJ rM.

Characters such as VEJ can be considered. If the specified character has such content, instead of reading a program for drawing the character, it will load a program that has a meaning based on the content of the character, such as a program for drawing a circle or a program for drawing a line. It is also possible to select a program answer for moving the displayed contents.

With reference to FIG. 2, among the data specified by the mouse 20 and detected from the database 31, the displayed figure type etc. is displayed.
The command mode may be switched based on the "straight line", "arc J", "character", the corresponding application program is selected, and at the same time, the attribute data, such as line type, color, etc., may be switched to the attributes of the specified figure. Predetermined pieces of attribute data can also be set so that they do not change as they were before the command mode was switched.

J)N In this embodiment, the application program corresponding to the selected command is stored in the external storage device 32, but the storage capacity of the main storage device is large, and the application program corresponding to the command is stored in the external storage device 32. Of course, the application program to be created may be stored in one storage device.

Furthermore, if no graphics, etc. are displayed on the display 36 yet, that is, at the beginning of use, processing in the graphic command mode, in which commands are specified using graphics, etc. that are already displayed, cannot be performed. In that case, display figures that are likely to be used frequently, such as straight lines, circles, English letters, etc., in advance in the corner of the display 36 in the normal display manner, and then use that display to execute commands in the graphic command mode. It is convenient to carry out the process.

In short, the point of this invention is that if there is a figure that is the same as the figure that you want to draw from now on among the figures that are already displayed, by specifying the figure that is already displayed using the pointing device, the displayed figure can be drawn. The idea is to create a device that allows you to select a program for drawing.

[Effect of the Invention] Therefore, according to the present invention, by specifying a desired figure among the figures already displayed, the device switches to the command mode for drawing that figure. of! Since the program for ``fi'i'' is selectively selected, it is possible to obtain a graphic data processing device that is easy to handle and allows commands to be specified quickly, accurately, and easily.
