[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drawing creation device for arranging symbols on a drawing and connecting them.

0002

2. Description of the Related Art In conventional drawing creating apparatuses of this type, it is necessary to create symbols to be placed on drawings in advance using another device and to save them as a library.

0003

[Problem to be Solved by the Invention] Therefore, if a new symbol is needed during drawing creation, or if a symbol needs to be changed for reasons such as balance on the drawing, drawing creation should be temporarily stopped. However, the symbols had to be created or corrected using other equipment, leading to a decline in work efficiency and the quality of the resulting drawings.

An object of the present invention is to solve such problems and provide a drawing creation device that can create symbols by itself.

[0005]

[Means for Solving the Problems] The present invention provides a drawing information storage unit that stores symbol information as a library, and a symbol arrangement that arranges symbols on a drawing based on the symbol information stored in the drawing information storage unit. In a drawing creation device, the drawing device includes: a wiring means for connecting symbols placed on the drawing; a drawing means for writing characters and lines for annotation; and an input device for specifying figures on the drawing. , a selection unit that selects annotation characters and lines drawn by the drawing means, or annotation characters, lines, and symbols based on an operation on the input device; and an annotation character selected by the selection unit. a symbol conversion unit that converts characters, lines, or symbols for annotation into symbols and stores them in the drawing information storage unit as the library; and annotation lines that connect to the symbols converted by the symbol conversion unit. The present invention is characterized by comprising a connection changing section for changing the connection to a connection.

[0006]

Embodiments Next, embodiments of the present invention will be described with reference to the drawings. FIG. 1 shows an example of a drawing creation apparatus according to the present invention. 8 is a display device for displaying drawings, and 1 is a mouse as an input device used for specifying figures on the screen of the display device 8. The drawing information storage section 7 stores drawing information, and symbol information is saved as a library. The placement means 2 uses a known method to
Symbols are placed on the drawing based on the symbol information stored in the drawing information storage section 7, and the wiring means 3 connects the symbols placed on the drawing by the placement means 2 using a known method.

[0007] The selection unit 4 selects information on characters and lines for annotation,
Based on the operation on the mouse 1, the drawing information is selected and taken out from the drawing information storage section 7. The symbol conversion unit 5 converts information on the annotation characters and lines selected by the selection unit 4 into symbols, and stores the results in the storage unit 7 as a library.

[0008] The connection changing section 6 searches for an annotation line that connects to the symbol converted by the converting section 5, and changes it to a connection between symbols.

Specifically, the drawing information storage unit 7 stores information such as that shown in FIG.
Symbol information, connection information, annotation character information, annotation line information, library characters, and library line information are stored in the formats shown in a) to (f).

Next, the operation when creating a symbol will be explained. FIG. 3 shows the original drawing displayed on the display device 8. Two symbols whose library name is S1 are A0
It is arranged with the symbol name 1, A02. At this time, the symbol information stored in the storage unit 7 is as shown in FIG. 6(a). Two symbols are connected by a single line, and the connection information stored in the storage unit 7 is shown in FIG.
).

Three annotation lines ■, ■, ■ are drawn on the drawing, and the annotation line information stored in the storage section 7 is shown in FIG. 6(d). The drawing also includes the annotation text “ADD
” is written surrounded by an annotation line ■, and the corresponding annotation character information in the storage unit 7 is shown in FIG. 6(c).

[0012] Library information includes library S
There is a line representing the outer shape of 1, and its information is stored in the storage unit 7 as shown in FIG. 6(f). Since the library character does not exist, information regarding it is not stored in the storage unit 7 (FIG. 6(e)).

Next, the operation of creating a symbol by converting the annotation line ■ and the annotation character "ADD" into a symbol will be explained. When the annotation line ■ and the annotation characters "ADD" are designated by operating the mouse 1, the selection section 4 retrieves these pieces of information from the storage section 7.

When the symbol conversion unit 5 receives the information from the selection unit 4, as shown in the flowchart of FIG. 4, it first finds the smallest x, y coordinate (5, 11) and uses it as the origin (step 301). , the annotation line is converted to coordinates with the origin at coordinates (5, 11), and is stored as a library line in the storage unit 7 as shown in FIG. 7(f) (step 302). As a result, for example, the second point (18, 11) is (
14,0) and stored. At this time, the converting unit 5 erases the annotation line information of the annotation line ■ stored in the storage unit 7 (FIG. 7(d)). The same process is performed for all annotation lines (step 303), and then the same coordinate transformation is performed for the annotation character "ADD", and the result is used as a library character, as shown in FIG. 7(e).
The data is stored in the storage unit 7 (steps 304 and 305). At this time, the conversion unit 5 deletes the information of the annotation character “ADD” stored in the storage unit 7. (Figure 7(c)). next,
The conversion unit 5 gives S2 as a library name to the library line and library character, stores it in the storage unit 7 (
Step 306), and instead of the annotation line and annotation character, symbol information is set as shown in FIG. 7(a) (step 307). In other words, the coordinates are the coordinates (5, 11) of the origin above, and the symbol name is A03.
is given, and S2 is stored as the library name.

Next, the connection change unit 6 searches for an annotation line that connects to the symbol A03, as shown in the flowchart of FIG. 5 (steps 401, 402). In this case, the annotation lines ■ and ■ are connected, so the changing unit 6 finds them and then searches for their respective connection destinations (step 403). Then, the annotation line ■ is connected to symbol A01, and the annotation line ■
is connected to symbol A02, so the connection information that connects symbols A01 and A03 and the connection information that connects symbols A02 and A03 are stored as connection information as shown in FIG. 7(b) (step 404). . At this time, the annotation line information is deleted (FIG. 7(d)). As a result of the above processing, a drawing as shown in FIG. 8 is obtained. Library S
2 can be created on the drawing, so symbols A01 and A02
You can easily create shapes with a well-balanced arrangement.

[0016]

As explained above, in the drawing creation apparatus of the present invention, characters and lines for annotations created on a drawing can be changed into symbols, so that the equipment can create symbols by itself. As a result, drawings can be created all at once without interrupting work, improving the efficiency of drawing creation work. Furthermore, since figures that are well-balanced with other symbols can be easily created, the quality of the created drawings is also improved.
