【発明の名称】立体モデルにおけるCADデータの変換方法
Document Type and Number:
Japanese Patent JP3057178
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To do without a large amount of data at the time of making the shape, etc., of a stereoscopic model a data base. SOLUTION: The projection drawing of a connecting rod 1 projected on a flat surface is surrounded by a rectangular line 11, the rectangular flat surface 12 surrounded this rectangle is divided crisscrossed by a prescribed width by means of straight lines 13 next and intersections Mij1 and Mij2 of a perpendicular 14 to the rectangular flat surface 12 and the surface of the connecting rod 1 are determined by setting each intersection Pij of these dividing lines 13 to be a start point. Next, what are obtained by respectively dividing the coordinate of each intersection P of the dividing lines 13, a distance Lsij1 from the rectangular flat surface 12 to the surface of the connecting rod 1 at the perpendicular 14 and a distance Lcij1 between the intersections with the surface of the connecting rod 1 at the perpendicular 14 by a reference distance B and making it dimensionless are stored as data.
