Abstract

PURPOSE:To easily and accurately judge where a symbol to be changed is registered at on a symbol master by reading out registered position information stored with the symbol in pairs, and discriminating the registered position of this symbol on the symbol master. CONSTITUTION:A registered position discriminating part 15 takes out symbol information 50 corresponding to the designated symbol on the drawing being prepared from a drawing data 6 during drawing, reads out registered position information 53 stored in the symbol information 50, and discriminates the registered position on a symbol master 5 of this symbol. Moreover, the registered position discriminating part 15 displays the registered position on the symbol master 5, on the screen of a graphic CRT 2 in order to communicate it to an operator. Then, the operator operates both a digitizer 4 for a symbol menu and a digitizer 3 for a cursor in order to designate the symbol to be changed on the symbol master 5, and displays it on the screen of the graphic CRT 2. Thus, the registered position of the symbol can be easily and certainly discriminated.

Description

[Detailed Description of the Invention] [Purpose of the Invention (Industrial Application Field) This invention is a computer aided computer aided system (CAD) that creates and edits drawings with the aid of a computer.
The present invention relates to a drawing creation/editing device such as a edDesign) system, and particularly to a determination method in the device for determining the registration position on a symbol master of a symbol pasted on a drawing to be created.

(Prior Art) In this type of drawing creation/editing device, pasting of symbols onto the drawing to be created displayed on the screen is conventionally done on a symbol master in which various symbols created in advance are registered. This was done by specifying the corresponding symbol.

Various types of such symbols are required in the process of creating and editing drawings, and a large number of similar symbols may be created and registered.

4 to 6 show examples of such symbols, a symbol master in which a large number of them are registered, and symbols pasted on drawings to be created.

FIG. 4 is a diagram showing an example of symbols created as necessary. Furthermore, FIG. 5 is a diagram showing an example of a symbol master in which a large number of symbols created in this way are registered together with their attribute information. Among the various symbols, there are symbols with similar shapes, and in some cases, Multiple symbols with different attributes but the same shape may be registered. Then, as shown in Figure 6, when pasting a symbol onto the drawing to be created displayed on the screen, specify and paste the symbol on the symbol master as shown in Figure 5. .

On the other hand, it may be necessary to change the symbol created and registered in this way and pasted on the drawing being created/edited. In such cases, a symbol is changed by specifying the symbol on the symbol master in which the symbol is registered.

(Problem to be solved by the invention) However, there are many symbols with similar or identical shapes,
If the symbol is registered on the symbol master, it becomes difficult to determine which symbol on the symbol master the symbol is to be changed. This has caused problems such as erroneously specifying and changing another symbol.

The present invention has been made in view of these conventional circumstances, and is a figure creation/editing device equipped with a discrimination method that allows easy and accurate determination of the position in which a symbol to be changed is registered on a symbol master. The purpose was to provide equipment.

[Structure of the Invention] (Means for Solving the Problem) In order to achieve such an object, in the figure creation/editing device according to the present invention, when creating a symbol and registering it in the symbol master, registered position information storage means for storing registered position information of a symbol registered in a pair with the symbol; and when a symbol pasted on a drawing to be created is specified, the registered position information is stored in a pair with the symbol. and a registered position determining means for reading position information and determining the registered position of the symbol on the symbol master.

(Function) If you use a figure creation/editing device with such a configuration, you can create a symbol, register it in the symbol master, paste the symbol registered in the symbol master onto the drawing to be created, and then print the symbol. Even if it becomes necessary to change the symbol, simply by specifying the symbol pasted on the drawing to be created, the registered position of the symbol on the symbol master can be easily and accurately determined.

That is, the registered position information storage means stores the registered position information of the symbol registered in the symbol master as a pair with the symbol, so when a symbol pasted on a drawing to be created is specified, the registered position information is stored in the registered position information storage means. The determination means reads out the registered position information stored in pair with the symbol, and determines the registered position of the symbol on the symbol master.

(Embodiment) FIG. 1 is a block diagram of the main parts of a graphic creation and editing device according to an embodiment of the present invention.

A symbol creation unit 11 controls symbol creation work, a symbol registration unit 12 controls symbol registration in the symbol master 5, and controls the pasting of symbols registered in the symbol master 5 onto drawings to be created. Along with the symbol pasting section 14 and the like, there is a control section 10 that controls symbol change designation work and various drawing creation/editing processes.

In addition, there is a graphic CRT 2 that displays drawings and symbols to be created, a cursor digitizer 3 that uses a cursor to indicate the position on the display screen of this graphic CRT 2, and drawing commands used when creating symbol shapes. There is a symbol menu digitizer 4 for selecting various symbol menus, and drawing data 6 for storing drawing information to be created.

A registered position information storage section 13 is provided for extracting registered position information of a symbol registered in the symbol master 5 and storing it as symbol information in pairs with symbol shape information and symbol attribute information of the symbol.

Further, when a symbol pasted on a drawing to be created is specified on the display screen of the graphic CRT 2, the registered position information stored as symbol information in pair with the symbol is read out, and the symbol master 5 of the symbol is read out. A registered position determination unit 15 is provided to determine the registered position above.

FIG. 2 is a diagram showing an example of the structure of symbol information created in the apparatus of this embodiment.

The registration position of the symbol indicates the registration position of the created symbol in the symbol master 5 together with the shape information 51 of the symbol created under the control of the symbol creation unit 11 and the symbol attribute information 52 indicating the attribute of the symbol. Information 53 is created and stored as symbol information 5o.

FIG. 3 is a flowchart showing the main operations of the apparatus of this embodiment, and the operations will be explained based on this figure. Note that FIGS. 4 to 6 are diagrams showing each side of a created symbol, a symbol master in which this symbol is registered, and a drawing to which this symbol is pasted.

(a) When creating and registering a symbol, the operator first inputs a cursor position instruction using the cursor digitizer 3 and inputs a drawing command instruction using the symbol menu digitizer 4 while repeating the graphic Create a desired symbol on the display screen of the CRT2, for example as shown in Figure 4 (Figure 3 (
Step 110 of a).

Symbol information about the symbol created in this way (
Shape information, attribute information, etc.) 50 are stored (registered) in the symbol master 5 according to instructions from the symbol menu digitizer 4. At this time, the location in the symbol master 5 where the symbol is stored can be specified by, for example, the symbol menu digitizer 4 or the like. The registered position information on the symbol master 5 thus determined is stored as a pair in the symbol information 5o by the registered position information storage section 13 (steps 120 to 130).

(b) When pasting the symbols created and registered in this way onto the drawing to be created, the operator tries to paste from the symbols registered in the symbol master 5 using the symbol menu digitizer 4. At the same time as selecting and specifying a symbol, the user operates the cursor digitizer 3 and instructs the position on the display screen of the graphic CRT 2 to paste the symbol (step 210 in FIG. 3(b)).
.

The symbol pasting section 14 takes out the symbol thus designated from the symbol master 5 and pastes it at the designated position on the drawing to be created that is displayed on the screen of the graphic CRT 2 (step 220).

(C) Furthermore, if, for example, an abnormality is found in the shape of a symbol that has already been pasted during drawing creation, and it becomes necessary to change the symbol that has already been pasted, then Changes must be made by specifying the appropriate symbol. In such a case, the operator first specifies a corresponding symbol using the cursor digitizer 3 on the drawing being created that is displayed on the screen of the graphic CRT 2 (step 31o in FIG. 3(c)).

The registered position determination unit 15 extracts the symbol information 50 corresponding to the specified symbol on the drawing being created from the drawing data 6 of the drawing being created, and extracts the registered position information 53 stored in this symbol information 50. The registered position of the symbol on the symbol master 5 is determined (step 3).
20).

Further, the registered position determining section 15 notifies the operator of the determined registered position on the symbol master 5 by displaying it on the screen of the graphic CRT 2. Then, the operator operates the symbol menu digitizer 4 and the cursor digitizer 3 to specify the symbol to be changed on the symbol master 5 corresponding to the displayed registered position,
It can be displayed on the screen of the graphic CRT 2 (step 330).

The operator changes the symbols displayed on the screen of the graphic CRT 2 by operating the symbol menu digitizer 4 and the cursor digitizer 3 (step 340).

In this way, the registered position of the symbol to be changed on the symbol master can be easily and accurately determined.

[Effects of the Invention] According to the graphic creation and editing device according to the present invention, when performing work such as changing a symbol that has already been pasted on a drawing,
When specifying a symbol on the symbol master in which this symbol is registered and performing changes, etc., simply specifying the symbol on the drawing allows you to easily and easily change the registered position of the symbol on the symbol master. Be able to make accurate determinations.

Therefore, even if multiple symbols with similar or identical shapes are registered on the symbol master, the corresponding symbol can be identified without fail, making this type of work easier and improving operability. This effect can be obtained.
