CONSTITUTION:When a cursor 3b to be the coordinate indicator of a digitizer 3 is positioned on a required position on the menu sheet 4 which is written on a table 3a of the reader 3 by pictographics and a required pictographic is selected and specified, the specified coordinates and is peripheral menu pictographic data are displayed on the display 2 together with a cursor mark through a processor 1 including a storage device 1a. Since the specified contents coincides with the displayed contents and CAD work can be executed without moving eyes from the display 2, the workability of CAD work can be improved.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is based on CAD (Computer Aided
Design) This relates to a CA/D system in which various commands used for work are entered by using a coordinate indicator to indicate pictograms written on a menu sheet attached to a tablet of a coordinate reading device. .

(Prior art) In recent years, various drawing commands such as various figures, letters, numbers, symbols, or their attributes used in CAD work such as drafting and design, as well as pictograms meaning other commands, are being read with coordinates. written in advance on a menu sheet that is attached to the tablet of the device either non-removably or removably;
On the other hand, the processing device is a CAD system that executes a corresponding command and displays it on a graphic display when a pictorial symbol on the menu sheet is designated using a coordinate indicator of the coordinate reading device.

By the way, in conventional CAD systems of this type, the menu on the menu sheet does not necessarily match the menu (display menu) displayed on the graphic display, or the details of the command selected on the menu sheet are not always displayed on the display. It was displayed as a menu on a graphic display.

[Problems to be Solved by the Invention] Therefore, when working by selecting desired commands one after another using pictographic instructions on a menu sheet, the operator must:
The line of sight must be constantly moved back and forth from the menu sheet to the graphic display, then from the graphic display to the menu sheet, and then between the menu sheet (tablet) and the graphic display. Moreover, at this time, as mentioned above, the menu on the menu sheet and the display menu do not necessarily match, and therefore the position of the corresponding pictogram between both menus also does not match, so you have to search for the pictogram that corresponds to the command each time. However, there was a problem in that work efficiency was significantly hindered.

An object of the present invention is to use a CAD system that allows commands to be given using pictograms on a menu sheet attached to a tablet of a coordinate reading device without taking one's eyes off the graphic display as much as possible during work, thereby significantly improving work efficiency. The goal is to provide a system.

[Means to solve the problem]

The above purpose is to attach a menu sheet on which pictograms representing various commands used in CAD work are written on a tablet of a coordinate reading device, and use a coordinate indicator of the coordinate reading device to read the pictograms on the menu sheet. In a CAD system in which a processing device executes a corresponding command by specifying a pictograph at a position and displays the result on a graphic display, the processing device executes a corresponding command and displays the result on a graphic display. This is achieved by displaying the pictograph part within a predetermined range around it on the graphic display.

[Effect]

As you get used to using the menu sheet, you will be able to roughly remember where a certain pictogram is located, so it is easy for the operator to position the coordinate indicator on the tablet (menu sheet) to the approximate location of the pictogram. It is possible.

The processing device displays on the graphic display the pictograms corresponding to the coordinate values given from the coordinate indicator and the pictograms in a predetermined range in the vicinity thereof, so it is possible to manually input the desired command to the processing device without directly looking at the menu sheet. I can do it.

This allows the operator to select a desired pictogram, that is, a command, written on the menu sheet and instruct the processing device while keeping the eye on the graphic display without moving the line of sight onto the menu sheet. Work efficiency is significantly improved.

〔Example〕

Hereinafter, the present invention will be described in detail with reference to the drawings. FIG. 1 is a block diagram showing an embodiment of a CAD system according to the present invention. In the figure, 1 is a processing device that controls the entire system, executes commands to be described later, etc., and 1a is a processor installed in this processing device 1. It is a storage device. Reference numeral 2 denotes a graphic display that displays figures, characters, etc. that are the results of executing commands, which will be described later. Reference numeral 3 denotes a coordinate reading device comprising a tablet 3a and a coordinate indicator, here a cursor 3b.

4 is a menu sheet, on which are written various drawing commands such as various figures, letters, numbers, symbols or their attributes used in CAD work, as well as pictographs meaning other commands, and the coordinate reading and acquisition device W3. (Tablet) 3a at a predetermined position or at a desired position (see Fig. 2).

Note that pictographic data similar to the content written on the menu sheet 4 is written in the storage device 1a.

Here, the processing device 1 includes a cursor 3 of the coordinate reading device 3.
By positioning b on a desired pictogram on the menu sheet 4, selecting and instructing that pictogram, its coordinates are given from the coordinate reading device 3, and the command corresponding to the pictogram with the coordinate values is executed. In addition to the traditional function of displaying information on a graphic display, it also has the following functions: That is, as shown in Fig. 3, cursor 3
When b is placed on the menu sheet 4, for example, at the position of the pictogram "ki", the corresponding coordinate values are sent from the coordinate reading device 3 to the processing device 1. As a result, the processing device 1 uses the storage device 1a.
Among the pictogram data similar to the menu sheet 4 stored in the memory, the pictographic data of the part corresponding to the sent coordinate values and a predetermined range in the vicinity thereof is read out and assigned to a part of the screen 2a of the graphic display 2. In the menu display area 2b, the pictogram corresponding to the coordinate value and the pictogram in a predetermined area in the vicinity thereof are displayed, enlarged here, and a cursor mark 2C is displayed in the portion corresponding to the coordinate value.

In this case, as the cursor 3b moves on the menu sheet 4, the coordinate values sent from the coordinate reading device 3 to the processing device 1 change accordingly, and the pictogram portion displayed in the menu display area 2b changes as well.

As the operator gets used to using the menu sheet 4, he or she will remember roughly where a certain pictogram is located, so the operator can move the cursor 3b on the tablet 3a (menu sheet 4),
It is possible to take the glyph to its approximate location. At this time, the pictogram part corresponding to the coordinate value given from the cursor 3b and the pictogram part in a predetermined area in the vicinity thereof are displayed on the graphic display 2 as described above, and the cursor mark 2C is also displayed, so the menu sheet 4 A desired command can be input to the processing device 1 without directly looking at the . If the position you have taken with the cursor 3b is off from the desired position, move the cursor 3b a little on the tablet 3a (menu sheet 4) while looking at the pictograph part displayed on the graphic display 2 and move the cursor 3b to the desired position. Just look for the emoji.

As a result, the operator selects a desired pictogram written on the menu sheet 4, that is, a command, and instructs the processing device 1 while keeping his/her eyes on the graphic display 2 without moving his/her line of sight onto the menu sheet 4. be able to.

In the illustrated example, only katakana characters are shown as pictograms, but the pictograms are not limited to these, for example, hiragana characters, alphanumeric characters, kanji, squares, circles, arcs, straight lines, various chain lines, center lines, and even patterns ( (including hatching). Further, in this specification, a plain colored part on the menu sheet 4, which means the coloring of the designated area, is also included in the pictograms.

Furthermore, a stylus pen or the like may be used as the coordinate indicator.

[Effects of the Invention] According to the present invention, various commands used in CAD work can be input by using a coordinate indicator to indicate pictograms written on a menu sheet attached to a tablet of a coordinate reading device. In a CAD system operated by CAD system, it is possible to indicate pictograms on the menu sheet, that is, commands, without taking your eyes off the graphic display during work, and it is effective to significantly improve work efficiency.
