Abstract

PURPOSE:To quickly and accurately search the specific characters on a designing drawing without performing any window processing by extracting only the character data out of a CAD data, storing this extracted data in a character store file, and then checking whether the selected characters are included in the character store file or not. CONSTITUTION:A computer aided design CAD system consists of a CPU 1, a magnetic disk 2, a computer CPU memory 3, a display data production part 4, a screen display part 5, a keyboard 6, and a character store file 8. Then all characters written on a drawing are stored in the file 8, and such a sequency is applied to check the number of characters that are selected by a light pen, etc., and stored in the file 8. Thus it is possible to quickly and accurately search the specific characters on a designing drawing without performing any window processing.

Description

[Detailed Description of the Invention] [Summary] Regarding a character search method in a CAD system, the purpose is to quickly and accurately search for a specific character on a design drawing without performing window processing. Select the characters on the screen with a light ben etc., store all the characters used in the drawing in the character storage file,
Determine what the selected character is, check whether the selected character is among the stored characters, and if so, store only that character separately, and indicate the location and number on the CAD screen. Configure to display information.

[Industrial Application Field] The present invention relates to a character search method in a CAD system.

[Prior Art] When designing a drawing using a CAD system (computer-aided design system), the size of the drawing to be designed does not necessarily correspond to the size of the display screen. For example, AI, B
When creating a design drawing with a size of 1, it is impossible to fit the entire drawing onto the display screen.

By the way, if you design such a large drawing, you can select a specific character (string) from among the characters drawn in the drawing.
You may want to find out how many there are.

In this case, the designer would perform window processing such as scrolling the entire screen or reducing the size of the screen, search for the desired character, and confirm the location and number of characters used.

[Problems to be Solved by the Invention] With the conventional character search method, if the drawing is about A4 size, it can be quickly confirmed.
, When it comes to large drawings such as BL size drawings or floor layout drawings, when you zoom out and search for the desired text, the text becomes small and difficult to see, and there are many windows to fit the drawing onto the display screen. When processing is performed, there is a problem that work efficiency deteriorates and there is a risk of missing the desired character.

The present invention has been made in view of such problems, and it provides a character in a CAD system that can quickly and accurately search for a specific character on a design drawing without performing window processing. The purpose is to provide a search method.

[Means for Solving the Problems] FIG. 1 is a flowchart showing the principle of the system of the present invention. The present invention selects characters on the CAD screen with a light pen, etc. (step 1), stores all characters used in the drawing in a character storage file (step 2), and determines what the selected characters are. (Step 3) Check whether the selected character exists among the stored characters (Step 4), and if so, store only that character separately (Step 5)
), information indicating the location and number of pieces is displayed on the CAD screen (step 6).

[Operation] All characters on the drawing are stored in a character storage file, and the number of characters selected with a light pen or the like is checked in the character storage file. By adopting such a sequence, it is possible to quickly and accurately check how many desired characters there are without scrolling the display screen.

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

FIG. 2 is a sequence diagram showing an example of the present invention.

In the figure, 1 is a CPU, and 2 is a magnetic disk that stores CAD data. From magnetic disk 2 to computer CPU
Graphical information such as points, lines, circles, characters, etc. is read into the memory 3. The contents of the computer CPU memory 3 are sent to the display data creation section 4, converted to display data, and displayed on the screen display section (
graphic display) 5. 6 is a keyboard connected to the screen display section 5 for inputting various commands.

On the other hand, only characters are extracted from the information in the computer CPU memory 3. The character information is composed of coordinate values in each of the x, y, and z directions, the number of characters (the number of character strings), characters, and other information, as shown in 7. From these character information 7, only the character coordinate values, number of characters, and characters are stored in the character storage file 8. As a result, all the character information in the CAD data is stored in the character storage file 8.

Specific character information indicated by the light pen is selected from among the drawings displayed on the screen display section 5 (9). It is determined whether a character using the selected specific character exists in the character storage file 8 (10). Then, only the characters that satisfy the conditions are read out and separately stored (11).

Next, information indicating the location and number of characters is stored in the computer CPU memory 3 (12).

The character location and number information stored in the computer CPU memory 3 is read out by the display data creation section 4, converted into display data, and displayed on the screen display section 5 as a processing result.

FIG. 3 is an explanatory diagram of the operation of the present invention. (a) shows the state before processing, and (b) shows the state after processing.

Reference numeral 20 indicates one drawing, and 21 indicates a portion of the drawing that is displayed on the display screen. Here, it is assumed that a character string containing the characters ABC is to be searched. When the characters ABC are selected with a light pen, the character search program as described above starts operating and searches for all character strings containing ABC from the character storage file. As a result, character strings containing ABC are searched for, including the outer frame 20, and the character strings containing the letters ABC are indicated by underlining, for example, as shown in (b), and at the same time, the number of character strings containing ABC is displayed. 4 is displayed. According to the present invention, even in a drawing that does not fit on the screen, the number of selected character strings can be displayed without performing window processing, and no characters will be overlooked.

In the above-described embodiment, the case where a character string including a selected character is extracted is taken as an example, but the present invention is not limited to this, and only the selected character itself may be extracted.

[Effects of the Invention] As described above in detail, according to the present invention, only character data is extracted from CAD data and stored in a character storage file, and characters selected with a light pen or the like are stored in the character storage file. By checking whether the character is included in the design drawing, it is possible to quickly and accurately search for a specific character on the design drawing without performing window processing, which has a great practical effect.
