2. Description of the Related Art Generally, when a developed connection diagram created by a CAD device is completed, the developed connection diagram data is stored in an external storage device or the like. After that, when it becomes necessary to change a part of the expansion connection diagram, the expansion connection diagram data that has been frozen in the external storage device is read into the CAD device and changed based on the change specification using the editing function of the CAD device. Work will be carried out. Further, when the expansion connection diagram is changed, the designer creates a changed article showing an outline of the work contents and inserts it in the drawing after the change work is completed.

By the way, the expansion connection diagram is not necessarily changed only once. Some drawings may be changed more than once. When the expansion connection diagram is changed in this way, other designers who have not performed the change work can see what process the drawing has become in its current form by looking at the change article. .

However, since the change history information that can be left on the expanded connection diagram in the form of a changed article is limited, the intention of a design change and the drawing contents before the change can be accurately communicated to other designers only by the changed article. I couldn't do that.

If the drawing contents before the change are saved in a complete state, the drawing contents before the change can be accurately grasped.
This causes the disadvantage that the storage capacity increases when the number of changes reaches a large number.

Further, since the changed article was created by the designer after the change work was completed, looking back on the work contents and relying on the memory, if the memory is not accurate, an accurate change history cannot be left. Moreover, there is a possibility of input omission, input error, and the like.

[0007]
