System and method of automatically creating supplemental segments in two-dimensional drawings.

摘要

The present invention is directed to an apparatus for and a method of automatically creating a supplemental segment in two-dimensional drawings. Two-dimensional drawing data concerning at least three views depicted based on orthogonal projection is previously stored in a drawing data storage device. Knowledge for recognizing three-dimensional solid model restored on the basis of the two-dimensional drawing data is previously stored in a knowledge storage device. The knowledge stored in the knowledge storage device is applied to the two-dimensional drawing data stored in the drawing data storage device, so that the three-dimensional solid model restored on the basis of the two-dimensional drawing data is recognized. An area where the supplemental segment is to be created is determined in the two-dimensional drawings on the basis of the recognized three-dimensional solid model. At least two end points of the supplemental segment to be created are determined in the determined area. The supplemental segment connecting the determined end points is finally created. <IMAGE>
