Field of the Invention The present invention relates to a drawing creating apparatus for creating a drawing by utilizing a CAD function, and more particularly, to a method of dividing drawing information created by a drawing creating apparatus into graphic information and other information. The present invention relates to a drawing creating apparatus which facilitates drawing management by managing the drawing, and is particularly suitable for use in designing a paper container for designing a paper container shape.

[0002]

2. Description of the Related Art Conventionally, when a drawing is created, CA
Using a computer equipped with the function of D, the operator draws graphic information as vector data using a mouse or the like while looking at the display screen, and attaches characters or symbols as code data if necessary. Information is input from a keyboard or the like and stored as one drawing information in a storage means such as a hard disk. When necessary, the drawing information is read out from the storage means and displayed on a screen of a display means such as a graphic display or output from an output means such as a printer for use.

As an example of drawing, there is a case where a paper container such as a paper box is designed. 2. Description of the Related Art Conventionally, when a paper container such as a paper box is created, a paper container design device using a CAD function is used to create a paper container drawing. Using this paper container designing apparatus, a paper container shape can be created, the name of the paper container can be input as character information, and registered as one drawing as a whole. Further, the paper container designing apparatus has a function of allocating a large number of created paper container shapes to one surface in accordance with the size of output paper. When the allocation is completed by the paper container designing device, the data is transferred to the die forming device, and a die for punching the paper container is generated. By punching out the paperboard paper using this mold, a large number of paperboards can be made. A drawing in such a paper container designing apparatus has a graphic such as a paper container shape and a character such as a title, but the graphic and the character are not separately managed but managed as one data per drawing.

[0004]

In the production of paper containers, the same paper container shape may be used as a package for different products as shown in FIG. In FIG. 4, “○ × chocolate” and “△ □ gum” are the same paper container F.
1 is used. The drawing data at this time has a structure as shown in FIG. 5 in a conventional drawing creation apparatus.
5, the drawing identification numbers are numbers for specifying the drawings, and the drawing identification numbers “D1” and “D2” correspond to the drawings D1 and D2 in FIG. 4, respectively. The attached information has code data such as characters or symbols corresponding to the drawing in one-to-one correspondence, and the arrangement position of the code data on the drawing as coordinate values from the origin of the drawing. The graphic information represents a graphic drawn in the drawing by vector data, and is recorded at a position from the origin of the drawing. In this case, the drawings D1 and D2 have the same paper container shape F1, but if the arrangement positions from the origin of the drawings are different, the graphic information will be completely different data.

[0005] On the other hand, the shape of the paper container is often corrected due to a problem in the manufacturing process of the paper container shape. For example,
It is assumed that a problem that the paper container shape F1 in the drawing D1 of FIG. 4 cannot be assembled as a paper box well due to the shape of the flap portion A in the folding step after the die cutting. At this time, the operator wants to make corrections on all the drawings having the paper container shape F1, but in the conventional drawing apparatus, the management of the figures in the drawings is managed by the coordinate values from the origin as shown in FIG. In addition, this is a management for each drawing, and does not manage the paper container shape F1 as an independent figure. Therefore, when the paper container shape F1 in the drawing D1 is corrected, the paper container shape F1 in the drawing D1 is corrected, but the paper container shape F1 in the drawing D2 is not corrected. For this reason, the operator has to make corrections by the number of drawings having the paper container shape F1, which is burdensome. Therefore,
SUMMARY OF THE INVENTION It is an object of the present invention to provide a drawing creating apparatus in which a graphic in a certain drawing is corrected so that the correction is reflected in all drawings having the graphic.

[0006]

According to a first aspect of the present invention, there is provided a drawing management system for storing drawing management information having drawing identification information, attached information, graphic identification information, and graphic arrangement information.

I do. According to the third aspect of the present invention, since a plurality of drawings share one graphic information, when the graphic information is corrected, the same effect as when all the drawing information is corrected can be obtained.

[0009]

Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a configuration diagram showing a paper container designing apparatus which is an embodiment of a drawing creating apparatus according to the present invention. The paper container designing apparatus shown in FIG.
It is composed of a calculation means 2, an output means 3, a display means 4, and a storage means 5. Here, in detail, the arithmetic means 2 is a relation control means 21 for searching drawing management information and graphic information according to an input and an instruction from the input instruction means 1, and combines the drawing management information and the graphic information for display. And data reflecting means 23 for separating the drawing data for display into drawing management information and graphic information and storing them in the storage means 5. Further, although not shown, the calculating means 2 has a drawing function which is a main function of the paper container designing apparatus. This drawing function utilizes a general CAD function, and can draw on a display screen using a mouse or a keyboard. The storage unit 5 has a drawing management information storage unit 51 and a graphic information storage unit 52.

As shown in FIG. 2, the drawing management information stored in the drawing management information storage unit 51 includes a drawing identification number for managing drawings, code data for output unique to each drawing, and arrangement information thereof. It is composed of attached information, a graphic identification number for associating graphic information to be displayed on each drawing, and graphic arrangement information that determines where on the drawing the graphic information is to be arranged. This graphic arrangement information has, for example, a position at which drawing of a graphic is started by a coordinate value from the origin of the drawing, and when a plurality of figures are arranged in one drawing, a plurality of figures are provided. In the graphic information storage unit 52,
Graphic information, which is vector data, and a graphic identification number are stored in pairs.

In the above paper container designing apparatus, the input instruction means 1 is actually a mouse and a keyboard, and the arithmetic means 2 is constituted by a CPU of a personal computer, a memory, and a program stored in the memory. Are realized by dedicated programs stored in the memory. The output means 3 includes a printer for outputting to paper, a data output device for outputting data for forming a die for punching a paper container, and the like. The display means 4 can be realized by a CRT display, and the storage means 5 can be realized by a hard disk.

FIG. 3 is a flowchart showing the processing operation of the paper container designing apparatus shown in FIG. When designing paper containers,
First, after activating the paper container designing apparatus, the operator uses the input instruction means 1 to input a drawing identification number, which is a unique key for each drawing. Here, the input drawing identification number is different from the case where the drawing identification number is new and has already been registered, and the processing is different. (Step S1)

(If the drawing identification number is new) The drawing management information storage unit 51 is searched with the input drawing identification number, and if there is no corresponding number, the drawing identification number input to the drawing management information storage unit 51 is retrieved. New data with is additionally registered. (Steps S2, S3)

Then, a drawing screen is displayed on the display means 4. First, the operator inputs the title of the drawing by using the input instruction means 1 using characters or symbols. Subsequently, the drawing of the paper container shape is performed by the input instruction means 1 using the drawing function. (Step S5)

After the drawing, when the operator gives an instruction to end the drawing by the input instructing means 1, the data reflecting means 23 recognizes the character data and the symbol data, which are the code data, among the created drawings as attached information, and It is stored in the drawing management information storage unit 51 together with the identification number. In addition, the paper container shape data as vector data is recognized as graphic information, and graphic information held as position coordinates on the screen is converted into graphic information of only a shape having no position coordinates. This graphic information is assigned a new graphic number and stored in the graphic information storage unit 52. The arrangement position of the graphic, that is, the drawing start position of the vector data, is registered in the drawing management information storage unit 51 as the graphic arrangement information together with the newly generated graphic number and the drawing identification number. (Step S6)

(When the drawing identification number is already registered) The drawing management information storage unit 51 is searched with the input drawing identification number, and if the corresponding number exists, the drawing management information storage unit 51 The code data of the attached information is extracted and displayed on the display screen as a title, and the graphic information is retrieved by searching the graphic information storage unit 52 from the graphic number, and the graphic information is arranged on the screen according to the graphic arrangement information. . For example, if the operator inputs the drawing identification number “D1”, the association control unit 21 searches for drawing management information having the drawing identification number “D1”, and adds the attached information “○ ×
In addition to extracting and displaying “chocolate”, the vector data of the graphic number “F1” is read from the graphic information storage unit 52, and drawn from the drawing start position recorded in the graphic arrangement information to display the paper container shape F1. (Step S2,
S4)

Next, when it is necessary to correct the displayed figure, the operator uses the drawing function to make correction using the input instruction means 1. For example, assume that the shape of the paper container is corrected in the drawing D1. (Step S5)

When an instruction to register a corrected drawing is issued, the drawing information D1 is separated into ancillary information C1 and graphic information F1 by the data reflecting means. It will be overwritten and saved. (Step S6)

As described above, when the shape of the paper container is corrected in the drawing D1, the graphic information F1 is corrected. Thereafter, when the drawing D2 is called on the display screen, since the drawing D2 has the graphic information F1, the corrected paper container shape is displayed. In other words, the paper container shape of the drawing D2 has been corrected without any correction.

When the drawing created as described above is output to the output means, when the operator designates the drawing identification number by the input instructing means 1 and gives an output instruction, as in the case of the display processing, the data combining means Extracts the attached information from the drawing management information having the designated drawing identification number, arranges it at a predetermined position in the output memory, and extracts the figure corresponding to the figure identification number from the figure information storage unit, and arranges the figure. The data is arranged at a predetermined position in the output memory according to the information, and the finally arranged data is output to the output means 3.

Although the embodiment of the present invention has been described above, the present invention is not limited to the above embodiment. For example, in the present embodiment, a mode using a stand-alone personal computer has been described. However, the storage means 5 is a large-capacity data server, and the input means 1, the arithmetic means 2, the output means 3, and the display means 4 A plurality of terminals may be connected as client machines. Further, in the present embodiment, the case where one graphic is arranged in one drawing has been described. However, in the drawing management information, a plurality of graphic identification numbers are made to correspond to one drawing identification number, and By setting the figure arrangement information, it is possible to arrange a plurality of types of figures in one drawing, and by setting a plurality of figure arrangement information for one figure information, it is possible to arrange one figure. It is possible to arrange a plurality of figures.

[0022]

According to the present invention, the drawing information is managed separately with the drawing management information and the graphic information. Therefore, when the figure is corrected on the drawing, the drawing management information is not changed and only the graphic information is corrected. As a result, the flexibility in correcting the drawing is increased. In addition, since one graphic information is shared by a plurality of drawing management information, a correction made on one drawing is reflected on another drawing, and the burden of the correction work is greatly reduced. This has the effect.
