DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be described with reference to the drawings. Referring to FIG. 1, which is a block diagram of a first embodiment of the present invention, in a drawing creating apparatus of this embodiment, a coordinate data file 1 stores coordinate data of a plurality of figures forming a drawing. The graphic data file 2 stores graphic data composed of this coordinate data. Drawing composition table 4
Stores the name of the graphic data file that constitutes the drawing. The storage unit 5 includes a coordinate data file 1 and a graphic data file
And the drawing configuration table 4 are stored. Graphic data creation unit 3
Converts the coordinate data into graphic data. The graphic data editing unit 7 creates a drawing by combining the graphic data. The drawing display unit 8 displays the created drawing. The input unit 6 gives an instruction for a display drawing and an instruction for graphic data forming a drawing.

FIG. 2 is a flow chart showing an example of the operation of this embodiment. The operation of this embodiment will be described with reference to FIG. 2 together with FIG. The graphic data forming the drawing is stored as coordinate data in the coordinate data file 1 of the storage unit 5 before creating the drawing (step A1). Input section 6
The display drawing name is designated by the graphic data editing unit 7 (step A2). The graphic data editing unit 7 retrieves the drawing configuration table 4 having the designated drawing name from the storage unit 5 (steps A3 and A4). If the drawing configuration table 4 of the designated drawing name does not exist, the graphic data name necessary for creating the drawing is input by the input unit 6 to create the drawing configuration table 4 (steps A5 and A6). A graphic data name required to compose a drawing is obtained from the drawing composition table 4, and it is searched whether this graphic data file 2 is stored in the storage unit 5 (steps A7 and A8). If the graphic data does not exist, the graphic data creation unit 3 creates the graphic data from the coordinate data file 1, and the storage unit 5
And save as graphic data file 2 (step A
9). On the other hand, if the designated graphic data file 2 has already been created and stored in the storage unit 5, no new graphic data is created. When all the required graphic data are gathered, the graphic data editing unit 7 collects the designated graphic data to form a drawing and displays it on the drawing display unit 8 (step A).
10, A11 and A12). FIG. 3 is a diagram showing a specific example of this embodiment. Referring to FIG. 3, it is assumed that the display instruction drawing name [drawing A] is given from the input unit 6. First, the graphic data editing unit 7 searches for a drawing configuration table [drawing A] in the storage unit 5 using the drawing name [drawing A] as a key. In the case of creating a new drawing, since the drawing configuration table [drawing A] does not exist, the drawing data names [graphic a], [graphic b] and [graphic c] forming the drawing are given from the input unit 6 and the drawing construction is performed. A table [drawing A] 41 is created. Next, the graphic data names [graphic a], [graphic b], and [graphic c] specified in the drawing configuration table [drawing A] 41 are coordinate data files [coordinate a], [coordinate a] when creating another drawing. b) and [coordinate c], and it is searched whether it is stored in the graphic data file 2. If the specified graphic data file does not exist, the graphic data creating unit 3 must create new graphic data. However, if graphic data is created and stored in the storage unit 5 when creating another drawing, the data is commonly used without newly creating graphic data, and the required number of graphic data files is increased more than necessary. Avoid storing it in the storage unit 5. When the figure files specified in the drawing configuration table [drawing A] 41 are prepared, the figure data editing unit 7
Converts the graphic data into a drawing format and displays it on the drawing display unit 8.

Next, referring to FIG. 4 which is a block diagram showing a second embodiment of the present invention, in the drawing creating apparatus of this embodiment, the coordinate data creating section 9 creates and modifies the coordinate data file 1. The correction file instruction table 10 stores a graphic data file name that can be coordinate data for data correction. The other components have the same functions as in the first embodiment.

FIG. 5 is a flow chart showing an example of the operation of this embodiment. The operation of this embodiment will be described with reference to FIG. 5 together with FIG. The operations of the coordinate data file 1, the graphic data file 2, the graphic data creation unit 3, the drawing configuration table 4, the storage unit 5 and the graphic display unit 8 (steps A1 to A12 in FIG. 5) are the same as in the first embodiment. The description is omitted. The coordinate data creation unit 9 writes the graphic data file name corresponding to the corrected coordinate data file 1 in the correction file instruction table 10 (step A13).
Before the drawing is edited, the drawing configuration table 4 of the drawing whose revision is instructed by the input unit 6 is compared with the correction file instruction table 10 (step A14). If the same graphic data file name exists, use the graphic data creation unit 2
The corresponding graphic data file 2 is revised and registered in the storage unit 5 (steps A15 and A9). After the figure data registration is completed, the file name of the revised figure data is deleted from the correction file instruction table 10 (step A1).
6). FIG. 6 is a diagram showing a specific example of this embodiment. Figure 6
Referring to, it is assumed that a display instruction drawing name [drawing A] composed of graphic data a, graphic data b, and graphic data c is given from the input unit 6. The graphic data editing unit 7
The drawing configuration table [drawing A] 41 and the graphic data file name written in the correction file instruction table 10 are compared. At this time, only when the file name of the graphic data a is written on the correction file instruction table 10, the graphic data a is revised by the coordinate data a and the drawing is edited. As a result, the name of the graphic data a is deleted from the correction file instruction table 10. When the graphic data specified in the drawing configuration table [drawing A] 41 are complete and the same file name does not exist in the correction file specification table 10, the graphic data editing unit 7 edits the graphic data as a drawing and displays the drawing. The drawing is displayed in part 8.
