Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drawing management apparatus for managing a large number of drawings including parent-child correspondences.

[0002]

2. Description of the Related Art Conventionally, a drawing management apparatus for managing a large number of drawings including parent-child correspondence has a configuration shown in FIG. That is, the image data storage area 102 of the database 101 stores the image data of each of a number of drawings, and the character code storage area 103 stores the storage area code 10 on the image data storage area 102 of each of a number of drawings.
4. A storage area code 105 of another drawing having a parent-child relationship with each drawing is stored in association with a character code 106 for identifying each drawing.

When an arbitrary drawing, for example, the drawing A is displayed on the display device and the related child drawings B and C are to be expanded, first, a list of the character codes stored in the character code storage area 103 is displayed. It is displayed on a display device (not shown), the character code 106 corresponding to the desired drawing A is selected from among them, and then a display instruction is given. Next, in order to expand the child drawing B related to the parent drawing A, the child drawing B is designated from the character code 106 of the parent drawing A, or the character code corresponding to the drawing B in the above character code list. By selecting again, the database 101 side specifies the image data storage area of the drawing B from the image data storage area 102, reads out the image data, and displays it on the display device.

As another database system, FIG.
The structure shown in is also known. This database 1
In 07, when a parent-child relationship is established between a plurality of drawings, for example, a relationship such as an overall view of a certain equipment and a drawing showing a part of the equipment in detail, the image data storage area 1 of each drawing is
The storage area on 08 is stored in the character code storage area 110 in association with the character code 109, and the coordinate range in the X-axis direction and the Y-axis direction of the parent drawing and the image data storage area of the child drawing related to the coordinate range are stored. This is a method of storing data in association with each other.

Therefore, for example, by specifying the character code 109 for the parent drawing A, the image data storage area 1
08, the image data is read from the image data storage area corresponding to the drawing A and displayed on the display device,
Further, by designating the X coordinate and the Y coordinate from the displayed image of the drawing A by a mouse or other pointing device, the child drawing corresponding to the coordinate range is searched, and if the coordinate range of the child drawing B is found, for example, The image data is read from the image data storage area of the child drawing B and displayed on the display device.

[0006]

However, in such a conventional drawing management apparatus, the parent-child relationship is described by the character code, especially in the database method in which the former drawing and the character code describing the attribute data are associated with each other. However, there is a problem that it is difficult to directly instruct a drawing being displayed to search for a child drawing, and it is impossible to expand a child drawing at a corresponding place as desired from the parent drawing.

In the latter case, in the database system in which the XY coordinate range is specified on the parent drawing and the child drawings are associated with each other, the drawing being displayed can be directly specified and expanded into the child drawing, but the contents of the drawing are edited. Then, when a part of the drawing is moved or changed, the coordinate range corresponding to the child drawing must be changed, which causes a problem that maintenance is troublesome.

The present invention has been made in view of the above conventional problems, and it is easy to develop drawings in a parent-child relationship,
An object of the present invention is to provide a drawing management device which can be easily operated and can be easily maintained when there are changes in drawing contents.
