Further, each unit graphic 21 is translated so that the combination reference position (0, 0) matches the writing position (α, β), and the allocation position of each unit graphic 21 is calculated. The allocating means 16 of FIG. 3 has the allocation positions 24 of the unit figures 21 ₁ , 21 ₂ , 21 ₃ and 21 _{4 respectively.}
(α, β)-(α + p, β), (α + p, β)-(α + p, β + q),
It is shown that it can be calculated as (α + p, β + q)-(α, β + q), (α, β + q)-(α, β).

When the allocation position 24 of each unit graphic 21 is obtained, the shape code 18 of each unit graphic 21 is stored in the allocation means 16 and the size code 19 is input from the code input means 6,
By inputting the shape code 18, size code 19 and allocation position 24 for each unit graphic 21 to the graphic creating means 15, each unit graphic 21 in the combination graphic 22 can be created. By combining this unit figure 21, the combined figure can be placed at any position on the CAD drawing 4.

Before writing the combination figure 22 on the AD drawing 4, the size code 19 of the combination figure 22 is inputted from the code input means 6 and stored in the figure management file 12. It is also possible to transfer the graphic management file 12 created by a word processor other than the computer 1 to the external storage device 10. When writing the combination figure 22 in the CAD drawing 4, the size code 19 of the combination figure 22 is read from the figure management file 12, the read size code 19 is input to the allocating means 16, and designated by the size code 19. CAD drawing 4 showing the size combination figure 22
Write on In the case of the embodiment shown in FIG.
Since the figure management file 12 storing various size codes 19 can be created relatively easily as compared with the method of storing the figure file 11 of FIG. 3, it can be expected to contribute to the efficiency of drawing the CAD drawing 4.

In the embodiment shown in FIG. 1, the shape, the interrelationship, or the number of each unit graphic 21 in the current combination graphic 22 to be written this time depends on the shape of the unit graphic 21 in the previous combination graphic 22 written last time.
If it is different from the shape of 21 or the mutual relation or the number, the shape code 18 and the relational expression 25 of each unit figure 22 of the combination figure 21 are input to the allocating means 16 and replaced with the existing shape code 18 and the relational expression 25.

The size of the device projection view can be easily matched with the size of the device managed by the device management file. An example of the device management file 14 is shown in FIG. The device management file 14 of FIG. 5 manages various device attributes of a plurality of devices by code signals, and each device attribute is represented by a character type or a numerical type in a predetermined number of lines. Of these device attributes, for example, the device attributes indicated by the number of lines 13, 14, and 15 are used as size data 19, and this size data 19 is assigned to
By inputting to 16, it is possible to make the size of the device projection diagram on the device plot diagram match the size of the device attribute.

Conventionally, the attributes of each device plotted on the device plot diagram are separately tabulated as a list called a device table. However, there is a problem that the shape and size of the device displayed in the device plot diagram do not always match the device attributes described in the device table. As described above, if the size of the device projection view on the device plot diagram is made to match the device attribute of the device management file 14 and the device attribute of the device management file 14 is displayed in the device table, The shape and size of the device projection view of can be easily matched with the device attributes described in the device table.
