  • Patent number: 5805858
    Abstract: 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.
