DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a graphic instruction receiving apparatus suitable for use in a computer-aided design (CAD) system.

[0002]

2. Description of the Related Art As shown in FIG. 4, a conventional CAD system generally includes a central processing unit (CPU) 1 for performing calculations for graphic processing based on a predetermined program, and a memory 2 for storing programs and data. A printer 3 that prints out programs and data on paper, a paper tape input / output device 4 that inputs and outputs programs and data via paper tape, and an image output device that displays and outputs created drawings and the like on a screen (CRT) 5, a keyboard 6 whose keys are operated by a designer to input data and commands of graphics processing, etc., and are moved and operated by the designer to input graphics and the above commands. A mouse 7 for operating keys, and an auxiliary storage device 8 for storing programs, data, and the like on a floppy disk or a hard disk. Consisting comprises a bus line 9 which connects the al components.

In such a conventional CAD system, when a designer designates a required figure among a plurality of figures displayed on a screen to the system, the figure is designated by the figure. A processing program as shown in FIG.
Received and entered. That is, in this processing program, first, in step 11, an input for designating a required graphic from the designer is waited, and the designer moves the pointer on the screen to the required graphic by moving the mouse 7, and 7
When a required graphic is designated by extracting (picking) the graphic by the key operation of (1), the graphic corresponding to the position of the pointer is detected in the next step 12, but the pointer is generally not easy to see. For this reason, not a point but a certain range such as a frame-shaped pointer P shown in FIG. 6 is used, so that the indication by the pointer includes a certain range, and therefore, FIG. 6 (a)
In a state where a plurality of figures are displayed densely as figure D ₁ to D ₅ shown, within the designer indicated by the pointer, a plurality of figures is detected.

Therefore, in this processing program, next, at step 13, a plurality of figures D ₁ are set within the range designated by the pointer.
ＤD _n (n is an integer corresponding to the number of detected figures) is checked. If a plurality of figures are not detected, at step 14, one figure _Da (a is an arbitrary figure) Integer) alone is detected, and if no figure is detected, the process returns to step 12 from there.
If only one graphic D _a is detected, step 15
Then, the figure D _a is determined and received as the figure instructed, input into the system, and as a result of the check in step 13, a plurality of figures D ₁ are set within the range indicated by the pointer.
If to D _n is detected, i.e., when the graphic D ₁ to D ₃ as in the case of the pointer P shown in FIG. 6 (a) is detected, for example, can not identify the indicated figures, in Step 16 First, it is assumed that a = 1, and in the following step 17, the display color of the graphic D _a , that is, the display color of the graphic D ₁ is _first changed to red as shown by oblique lines in FIG. as shown, in the corner of the position of the screen that does not get in the way of the graphic display, are displayed side by side and the OK menu M ₁ and NEXT menu M _2.

In the processing program, in a subsequent step 18, an input for designating a menu is awaited from the designer, and the designer moves the pointer on the screen to a necessary menu by moving the mouse 7, When the menu is specified by extracting (picking) the menu by the key operation of the mouse 7, the menu corresponding to the position of the pointer is detected in the next step 19, and in the next step 20, the menu within the range indicated by the pointer is detected. NEXT menu M ₂ is checked whether it has been detected, not pick NEXT menu M ₂ are considered designer to be the current figure D _a need figures, as a result, NEXT menu M ₂ has not been detected without it, the program proceeds to step 15, receives and determines that the current figure D _a the indicated figures, and inputs into the system.

On the other hand, for example, as shown in FIG.
The designer thinks that this graphic Da is not _a necessary graphic and
Because you pick EXT menu M _2, Step 20
In the case where the result of examining NEXT menu M ₂ is detected, control proceeds to step 21, restore the display color of this figure D _a, in the next step 22, a = a + 1 (provided that a > after when n was = 1) and a, returns to step 17, the display color of the next graphics D _a, that is, for example FIG. (c)
With varying red display color of the graphic D ₂ as shown by hatching in the OK menu M ₁ as shown in FIG. (C) NEXT
Displayed side by side and a menu M _2, thereby subsequently, as a result of investigating again in step 20, for example, as shown in FIG. (C), this figure D _a designer believes is a graphical required pointer P the move to OK menu M ₁ above, the O
When the K menu M ₁ is detected as that extracted (pick), the program proceeds from there to step 15, the figure D _a
Is determined and received as the designated figure, and is input into the system.

[0007]

However, according to such a conventional processing program, when a plurality of figures are displayed in a dense manner and some of the plurality of figures are sequentially designated, the CAD system is used. The designer operates the mouse 7 to move the pointer P to the position on those figures and the OK menu M _{1 in} the corner of the screen far away from them until the instructions are received and input for all the necessary figures.
And since the NEXT menu by reciprocating between M ₂ is display position performs pick menus and graphics, it must be repeated each time the task of, is wasteful to movement of the hand, designer fatigue In addition, there is a problem that it takes time to specify necessary graphics.

[0008]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a graphic instruction receiving apparatus which advantageously solves the above-mentioned problems of the conventional processing program. The device is used as part of a CAD system, as shown in FIG.
An apparatus for receiving an instruction of a specific figure when a plurality of figures are detected by figure extraction, wherein the plurality of detected figures are sequentially displayed on a screen one by one by exchanging figures to be displayed. At the same time, a plurality of figure detection display means 31 for erasing the display of the detected figure other than the figure to be displayed and displaying information indicating that a plurality of figures are detected on a screen, In the state where one of the graphics is displayed on the screen, when a portion other than the graphics being displayed is detected by graphic extraction, the plurality of graphics detection and display means is made to exchange the graphics to be displayed, When a figure being displayed is detected by figure extraction, designated figure judging means 32 for judging the figure as a designated figure and receiving the figure is provided.

[0009]

In such an apparatus, a plurality of graphic detection display means are provided.
31 replaces the graphics to be displayed, thereby simultaneously displaying the plurality of detected graphics on the screen one by one, simultaneously erasing the display of the detected graphics other than the graphics to be displayed, and By displaying information indicating that a plurality of figures have been detected on the screen, the designer is requested to specify and specify a necessary figure, whereby one of the plurality of detected figures is displayed on the screen. The designer determines that the currently displayed figure is not the required figure and extracts the part other than the displayed figure by figure extraction, and as a result, When a part is detected, the designated figure determining means 32 causes the plural figure detection / display means to replace the figure to be displayed, display the next figure on the screen, and repeat this.
When the designer determines that the currently displayed figure is a necessary figure and extracts the displayed figure by figure extraction, as a result, when the displayed figure is detected, the designated figure determining means 32 The figure is determined and received as the designated figure.

Therefore, according to this apparatus, when a plurality of figures are displayed in a dense manner, and when some of the plurality of figures are sequentially indicated, the pointer is being displayed by operating the mouse or the like. It is only necessary to repeat the work of extracting a figure by reciprocating between a position on the figure and a position slightly deviated therefrom, so that there is no waste of hand movement and less fatigue of the designer At the same time, it is possible to easily specify necessary graphics.

[0011]

Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 2 shows a graphic instruction as an embodiment of the graphic instruction receiving apparatus for a CAD system according to the present invention, which is incorporated into the ordinary CAD system as shown in FIG. 4 by modifying a part of its operation program. 5 is a flowchart showing a processing program executed by a receiving command. In this processing program, a designer can select a required graphic among a plurality of graphics displayed on a screen by using the C command.
When instructing the AD system, first, in step 33, the system waits for an input from a designer to designate a necessary figure.
By moving the pointer on the screen over a required figure by moving the mouse 7, and extracting (picking) the figure by key operation of the mouse 7, the necessary figure is designated. A figure corresponding to the position of the pointer is detected. As described above, the pointer is usually a frame-shaped pointer P shown in FIG. 3 similar to that shown in FIG. 6, for example.
It is said that it has a certain range like
The indication by the pointer includes a certain range, and therefore, is the same as that shown in FIG.
As in figure D ₁ to D ₅ shown in (a), when a plurality of figures are displayed densely, within the designer indicated by the pointer, a plurality of figures is detected .

Therefore, in this processing program, next, at step 35, a plurality of figures D ₁ are set within the range designated by the pointer.
ＤD _n (n is an integer corresponding to the number of detected figures) is checked, and if a plurality of figures are not detected, at step 36, one figure _Da (a is an arbitrary number) integer) only examines whether it has been detected, if one graphic was detected is from there back to step 34, if only one graphic D _a is detected, control proceeds to step 37 in receiving and determining a figure that has been instructed to the figure D _a, and inputs into the system. Also step
If a plurality of figures D _{1 to} D _n are detected within the range indicated by the pointer as a result of the check at 35, for example, FIG.
In the case where the graphics D _{1 to} D ₃ are detected as in the case of the pointer P shown in (a), the designated graphic cannot be specified.
39, the display color of the figure D _a, i.e. the first together with changing the display color of the figure D ₁ for example red, as shown by hatching in FIG. (B), the detected figure other than the figure D _a, i.e. initially the as shown in FIG. (b), figure D ₂ and figure D ₃
Is deleted from the screen, and, for example, "Plural figures have been picked. Please select one."
Information indicating that a plurality of figures have been detected is displayed on the screen.
As a result, the designer can easily know that a plurality of figures have been picked, and can easily confirm the figure that is a candidate for selection this time.

Then, in the processing program, in the subsequent step 40, the designer waits again for an input for designating a required figure from the designer, and the designer holds the mouse 7 at the current position without moving the mouse 7 and moves the mouse 7 on the screen. The pointer is held on a required figure, or the pointer on the screen is moved to a position slightly deviated from the required figure by a moving operation of the mouse 7, and is deviated from the figure or the figure by a key operation of the mouse 7. When the position is indicated by extracting (picking) the figure, the next step 41 detects a figure or the like corresponding to the position of the pointer, and in the next step 42, the figure detected within the range indicated by the pointer is detected. or did, or detected investigated whether graphic D _a did not have a current selection of candidates in the figure, the figure D thinking designer to be the current figure D _a need figures _a Pick a result, there is detected figure, yet in the case where there is graphic D _a which is a candidate for this selection in the detected figure, the program proceeds to step 37, this figure D _a is determined and received as the designated figure, and input into the system. That is,
If the required graphic is the first display graphic, for example,
The designer can specify the figure only by holding the current position without moving the mouse 7 and performing the key operation again.

On the other hand, for example, as shown in FIG.
Since the designer considered that the current graphic Da was not _a necessary graphic, and picked a position off the graphic, as a result of the check in step 42, there was no graphic detected within the range indicated by the pointer, or If graphics D _a which is the current selection of candidates in the detected figure was not, proceeds to step 43, (in the case of however a> n a = 1) a = a + 1 and, the following in step 44, for example, by displaying the following figure D _a as figure D ₂ on the screen shown in FIG. (c), the flow returns to step 39. And that step 39
In, for graphic D ₂ with varying red display color of this figure D _a, as shown by hatching in FIG. (C), the figure D
first detected shapes other than _a, i.e. in the above case to erase the display of graphic D ₁ and figure D ₃ as shown in FIG. (c) from the screen, together with a plurality of shapes as described above are the information indicating that the detected displayed on the screen, thereby subsequently, as a result of investigating again in step 42, for example as shown for figures D ₂ in FIG. (c), figure D being displayed currently
_{when a} is considered a designer as a graphical required is slightly move the pointer P to its figure D _a, is detected as that picks the figure D _a is the step from there 37
To proceeds, receives and determines that the figure D _a the indicated figures, and inputs into the system.

Therefore, the above steps 38, 39, 43, 44
It corresponds to the plural figure detection display means 31 and also corresponds to step 3
7, 40 to 42 correspond to the pointing figure determining means 32, and according to the processing program, a plurality of figures D ₁ to
In a case where some of the plurality of figures are sequentially indicated in a state where D _n is displayed densely, the pointer P is slightly deviated from the position on the figure being displayed by operating the mouse 7. It is only necessary to repeat the work of extracting figures by reciprocating to and from the set position, eliminating the waste of hand movements, reducing the fatigue of the designer, and easily specifying the necessary figures. Can be done.

Although the present invention has been described based on the illustrated examples, the present invention is not limited to the above-described example. For example, the present invention can be applied not only to a case where the pointer is in a frame shape but also to a cross shape, The present invention can be applied to a case where the moving operation is performed not by the mouse 7 but by operating means such as a so-called trackball, and the operation amount can be reduced, and the above-described effects can be obtained. The information indicating that a plurality of figures have been detected is displayed in characters in the above example, but may be displayed in a specific symbol.

[0017]

As described above, according to the graphic instruction receiving apparatus for a CAD system of the present invention, when a plurality of graphics are displayed in a dense manner, when some of the plurality of graphics are sequentially specified, a mouse is used. The operation such as moving the pointer back and forth between the position on the displayed graphic and the position slightly deviated from it to perform the graphic extraction only needs to be repeated. As a result, it is possible to reduce the fatigue of the designer and to easily specify necessary graphics.
