A method for automatic mid-surface extraction of 3D CAD model for product anaysis

摘要

PURPOSE: An automatic medial surface extracting method of a 3D CAD model for product analysis is provided to rapidly and exactly search a face pair to be extracted to a medial surface through selective searching method. CONSTITUTION: Thickness surfaces and edge pairs of each thickness surface is searched by performing MAT(Medial Axis Transform)(S1). A face pair connected to the thickness surfaces is searched(S2). Other face pairs connected from registered face pair is successively searched. According to each face pair, medial surface pieces are generated(S3). The medial surface pieces are interconnected(S4).
