DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a system for exchanging drawing data in different data formats of different graphic processing apparatuses.
In particular, it relates to a dimension line data conversion method.

[0002]

2. Description of the Related Art Conventionally, this kind of drawing data exchange system reconstructs a deleted part from other related graphic information when a dimension line of drawing data of a graphic processing device A is partially deleted. The deleted portion is hidden and converted into a dimension line handled by the graphic processing apparatus B, or converted as a simple element without being converted as a dimension line.

[0003]

In the above-described conventional drawing data exchange method, when a dimension line is partially deleted,
There is a drawback that a restoration process for creating a deleted portion using other incomplete element information must be performed using another dimension line component. In addition, restoration cannot be performed correctly due to incompleteness, and an illegal operation may occur in the graphic processing apparatus B. If the restoration process could not be performed, it could not be converted as a dimension line.

In view of the above, it is an object of the present invention to restore a deleted portion by dividing a dimension line into a plurality of dimension lines when there is a partially deleted dimension line. The object of the present invention is to create dimension line data of the graphic processing apparatus B using dimension lines as dimension lines.
