摘要

PROBLEM TO BE SOLVED: To provide a correction device of wire flame data of a three-dimensional CAD system wherein an error generated by data conversion with an intermediate file and the like easily corrected in a short period time even by an unskilled operator.;SOLUTION: A ridge line of the wire flame data, a peak point and a ridge line-peak point relation are recorded (a step S1). Then, to make following operations easy, a process to change an arc and a spline into a line segment is performed (a step S2). A peak point merge is applied to far peak point, and a line segment merge is applied to a line segment for barely crossing and the like, a deletion process and the like are applied to a line segment having a protruding part (steps S3 to S7). Distortion of a plane is eliminated by performing a flattening process of a plane enclosed by boundary line segments (a step S8). Finally, an arc restoration process is preformed (a step S10) by executing fillet generation in a three-dimensional form for which planes are developed.;COPYRIGHT: (C)2004,JPO&NCIPI
