[0002]

2. Description of the Related Art In a CAD system for creating a drawing of piping or the like, when checking the created CAD drawing,
A code number indicating a target portion on a CAD drawing is searched for as a search target, and that portion is displayed at the center of the CRT. FIG. 8 is a configuration diagram showing a part of the configuration of such a conventional CAD system. 1 is a CRT for displaying a CAD drawing or the like drawn by a CAD system, 2
Is a mouse which is a pointing device for inputting a position on the CRT 1, etc., 3 is a keyboard for inputting character data such as numerical values, 4 is an external storage unit in which CAD drawings created by this CAD system are stored, 5 is The figure number of the CAD drawing stored in the external storage unit 4 is CRT1.
And displays the CAD drawing corresponding to the figure number indicated by the pointer on the CRT 1 by operating the mouse 2 in the external storage device 4.
This is a CAD drawing search unit to be extracted.

[0003] In addition, 6 is a drawing of the captured CAD drawing on a CRT.
The drawing display unit 7 displayed in 1 searches for the corresponding device from the CAD drawing fetched from the external storage device 4 using the input device code as a keyword so that the searched device is displayed in the center of the CRT 1. This is a device search unit to perform. The display magnification of the CAD drawing taken out of the external storage device 4 displayed on the CRT 1 can be changed by receiving the input instruction from the keyboard 3 by the drawing display unit 6.

[0004] Next, the operation of search display in the CAD system will be described with reference to the flowchart of FIG.
First, the CAD drawing search unit 5 selects a CAD drawing to be checked from the menu displayed on the CRT 1 by moving the pointer displayed on the CRT 1 with the mouse 2 (step S91). . Thus, the CAD drawing search unit 5 takes out the selected CAD drawing from the external storage unit 4 and displays it on the CRT 1 (step S92). Here, in this case, since the CAD drawing is confirmed, it is set to the device search state (step S9).

[0006]

Since the conventional CAD system is configured as described above, if the display magnification is small or the drawing density is high, where is the searched device? There was a problem that was not clear. In the above-described step S92, CAD is added to CRT1.
The whole drawing is displayed, and the display of each fine part such as a valve constituting the CAD drawing is displayed very small or not accurately displayed. Therefore, it is impossible to accurately confirm the device on the CAD drawing in this state. On the other hand, when the CAD drawing taken out of the external storage unit 4 is displayed on the CRT 1 at a high magnification, each device can be checked accurately. However, since the device to be searched is only displayed in the center of the CRT 1, the CAD including the device is complicated.
In the case of the drawing, it is not possible to distinguish exactly which device was searched.
