Here, a description will be given with reference to the drawing of the result of identification of the processing information already allocated to the shape of the sheet.

FIG. 3 shows a product shape included in the shape of the sheet.

In the shape of the sheet, the forming process 51 of the upward projection, the forming process 53 of the downward projection, the forming process 55 of the upward burring, and the forming process 57 of the downward burring are performed.
, Trimming 59, external processing 61, and hole processing 6
3 and the like are included.

In the case of the present embodiment in which the protrusions are formed in the shape of the above-mentioned sheet-shaped sheet, the setting data of the identification data Si is as follows.
As shown in FIG. 4A, in the case of forming the upward projection, it is displayed on the display screen unit 7 as shown in FIG. 4B. Here, the setting of the identification data Si is, for example, that the color of the line segment is light blue, the line type is not changed, and the line segment thickness is not changed, so the screen display is displayed as shown in the figure ( It is actually displayed in color). As shown in FIG. 4C, in the case of forming the downward projection, the screen display shows the identification data Si.
Is set to, for example, the color of the line segment is dark blue, the line type is not changed, and the line segment thickness is not changed (in other words, the line type, the line thickness, etc. are the original figures) ), FIG. 4 (d)
Is displayed as shown.

As shown in FIG. 4 (e), in the case of the upward burring, the identification data Si is set, for example, in which the color of the line segment is blue, the line type is not changed, and the line segment thickness is changed. Since there is no display, the screen display is as shown in FIG.
As shown in FIG. 4G, in the case of the downward burring processing, the identification data Si is set, for example, such that the color of the line segment is brown, the line type is not changed, and the line segment thickness is not changed. Therefore, it is displayed as shown in FIG.

That is, in the forming portion of the protruding portion, the color is displayed in different colors depending on the upward and downward forming, and the figure is displayed differently depending on the shape of the forming process. Therefore, the shape and the protruding direction of the formed part can be identified by looking at the displayed figure and color coding.

The display of the processing order group includes the identification data Si
If the setting is hole drilling, for example, the line segment color coding is unchanged, the line type is unchanged, and the line segment thickness is thin,
It is displayed on the screen as shown in FIG. In the case of trimming and external processing, the setting of the identification data Si
For example, without changing the color coding of the line segment, without changing the line type,
Since the thickness of the line segment is the middle line, it is displayed as shown in FIG. When the processing order group is the forming processing, the setting of the identification data Si is such that the line segment coloration is not changed, the line type is not changed, and the line segment thickness is a thick line. As shown in c).

That is, in the display of the processing order groups, the line segments have different thicknesses for each processing order group, so that it is easy to identify that they belong to the same processing order group.

By the way, as shown in FIG. 3, for example, the processing order fixed information is added to the processing order group in the processing order group for identifying the forming processing 51, the trimming processing 53, the external processing 61, and the hole processing 63. Since only the case of the trimming 59 and the case of the outer shape processing 61, the trimming 5
In the case of No. 9, setting of colors from the first processing to the final processing,
By changing the setting of the color of the final processing from the first processing of the outer shape processing 61 and changing the setting, it is possible to identify the processing order in each processing group.

In the processing order fixed information, when the setting of the identification data Si is the first processing, for example, the color of the line segment is white, the line type is not changed, and the line segment thickness is not changed. When the setting of the identification data Si is the second processing, for example, the color of the line segment is red, the line type is not changed, and the line segment thickness is not changed. In the case of the third processing, for example, the color of the line segment is green, the line type is not changed, and the line segment thickness is not changed. In the case of the fourth processing, for example, the color of the line segment is yellow, the line type is not changed, and the thickness of the line segment is not changed.

That is, in the display of the processing order fixed information, since the color is different for each processing order within the same processing group, the processing order within the same processing group can be easily identified.

Next, the flow of obtaining the input data Ni and changing the color of the line segment, the line type, and the line segment thickness will be described with reference to FIGS.

It is determined whether the element read in 713 is a line segment related to the processing order group. If it is determined in step S719 that the line segment is related to the shape of the processing order group, the process proceeds to step S721. In the processing of step S721, data of the color classification, the line type, and the line segment thickness set for the processing order group identification using the identification data Si are added to the line segment related to the shape of the processing order group. If it is determined in step S719 that the line segment is not a line segment related to the shape of the processing order group, the process proceeds to step S723.

In the process of step S723, step S723
It is determined whether the element read in 713 is a line segment related to the processing order fixed information. If it is determined in step S723 that the line segment is related to the shape of the processing order fixed information, the process proceeds to step S725. In the process of step S725, the data of the line classification, the line type, and the line segment thickness set for the identification of the processing order fixed information with the identification data Si is added to the line segment related to the shape of the processing order fixed information. If it is determined in step S723 that the line is not a line segment related to the shape of the processing order fixed information, the process proceeds to step S727.

In the process of step S727, data obtained by assigning a line segment color, a line type, and a line segment thickness to each line segment is stored in the drawing data file 27 as described above.

In the process of step S729, it is determined whether or not the process has been performed on all the line segments of the sheet-sheet data Ti. If it is determined in step S729 that the processing has been performed on all the line segments of the sheet preparation sheet data Ti, the process proceeds to step S731. Next, step S
