Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drawing management method for a CAD system, and in particular, creates a relationship between drawings, displays the relationship, and manages the relationship data between the created drawings and the drawing data. The present invention relates to a drawing management device.

[0002]

2. Description of the Related Art A drawing management device of a conventional CAD system manages each drawing data unit. For example, in the drawing management device described in Japanese Patent Laid-Open No. 1-21177, a data hierarchy is formed by hierarchically separating each data of roads, house frames, and pipelines in the facility drawing based on the data of the facility drawing. When changing the data hierarchy, extract the specified figure that should be changed and display it in the drawing display area of the display.Use the mouse etc. to search for the symbol in the displayed figure data and change it. If the symbol cannot be changed by judging the consistency of the hierarchy, handle the error. This drawing management apparatus executes rewriting of the data hierarchy for one drawing while displaying the drawing itself of the drawing data, and is managed so as to change the drawing contents while displaying the drawing data for each drawing.

Embodiments of the present invention will now be described with reference to the drawings.

FIG. 1 is a block diagram showing a drawing management apparatus according to an embodiment of the present invention. In the figure, the drawing management apparatus of the present embodiment is composed of an input device 1 such as a keyboard and a mouse, a CAD
A system 2, a display 3, an external storage device 4,
And block 5. Here, a mechanical drawing created by CAD is assumed as the drawing.

The CAD system 1 includes a function selection unit 6 for selecting each unit 7 to 11 described below according to a command input from an input device 2 such as a keyboard connected to the outside.
A drawing creation / editing unit 7 for creating shape data such as straight lines, circles, characters, and other shapes to be stored in a mechanical drawing and coordinate data indicating the position of the shape in accordance with an input from the input device 2, and editing the drawing. , A drawing database 14 that stores the shape data generated by the drawing creation / editing unit 7 by addressing each drawing, and drawing relationship creation that creates and edits data that displays the relationship between drawings in accordance with input from the input device 2. An editing unit 8, a drawing relationship storage unit 13 that stores the drawing relationships created by the drawing relationship creation and editing unit 8, and a relationship between drawings created by the drawing relationship creation and editing unit 8 according to an input from the input device 2 are displayed. 3 is a drawing relation display control unit 9 for performing control to be displayed on the display 3, and shape data created by the drawing creation / editing unit 7 and data showing a relationship between drawings created by the drawing relationship creation / editing unit 8 A main storage unit 12 having the function of a buffer for temporarily storing, when the plotter output command is inputted from the input device 2 main storage unit 12 or drawing database 1
A plotter output unit 11 for reading drawing data from the drawing 4 and outputting it to a plotter 5 connected to the outside; The drawing output unit 10 reads the drawing data and outputs it to the external storage device 4 connected to the outside.

The input device 2 may be, for example, a keyboard from which various commands are issued by the CAD system 1.
In response to the command contents, the function selection unit 6 selects one of the drawing creation / editing unit 7, drawing relationship creation / editing unit 8, drawing relationship display unit 9, drawing output unit 10, and plotter output unit 11. To display the drawing as an image on the externally connected display 3 as shape data, or to output the drawing data and the data for displaying the relationship between the drawings to the external storage device 4 connected to the outside. , Output drawings to the plotter 4 connected to the outside.

First, when a command for selecting the drawing creation / editing section 7 is input from the input device 2, the function selecting section 6 calls the drawing creation / editing section 7. The drawing creation / editing unit 7 creates and edits line, circle, character, and other shape data on the main storage unit 12 according to an instruction input from the input device 2. The operator creates and edits the necessary shape data by inputting a command from the input device 2 while looking at the image data displayed on the display 3. At this time, when a drawing data storage command is input from the input device 2, the drawing creation / editing unit 7 stores the drawing data in the main storage unit 12 in the drawing database 14.

When a command for selecting the drawing relation creating / editing unit 8 is input from the input device 2, the function selecting unit 6 calls the drawing relation creating / editing unit 8. Drawing-related creation / editing section 8
In accordance with the input information from the input device 2, the related information between the drawings such as the parent-child relationship and the quoted relationship between the plurality of drawings is created and edited on the main storage unit 12. Further, at this time, when a storage command of drawing-related data is input from the input device 2, the drawing-related creating / editing unit 8 stores the data of the main storage unit 12 in the drawing-related storage unit 13. Drawing-related storage unit 1
3 has 111-X, 999 related drawings as shown in FIG.
-Sequentially stored with drawing numbers such as A.

When a command for selecting the drawing relation display unit 9 is input from the input device 2, the function selecting unit 6 calls the drawing relation display unit 9. The drawing relationship display unit 9 stores the relationship data between drawings related to the drawing input from the input device 2 in the main storage unit 1.
2 or from the drawing-related storage unit 13 and displayed on the display 3.

When a command for selecting the drawing output unit 10 is input from the input device 2, the function selecting unit 6 calls the drawing output unit 10. The drawing output unit 10 calls the drawing relationship display unit 9 to display a relationship between drawings as shown in FIG. 2 as a list, and inquires of the operator which drawing should be output to the external storage device 4. The operator uses the input device 2 to instruct which drawing should be output to the external storage device 4. The drawing output unit 10 extracts the input drawing from the drawing database 14, extracts the drawing-related data of the drawing from the drawing-related storage unit 13, and outputs it to the external storage device 4.

When a command for selecting a plotter output command is input from the input device 2, the function selection unit 6 calls the plotter output unit 11. The plotter output unit 11 reads the drawing data from the main storage unit 12 and the drawing database 14, and outputs the read drawing data to the plotter 4 connected to the outside.

The plotter 4 plots a drawing based on the drawing data output on the paper on a predetermined paper.
