Understanding three-view drawings of mechanical parts with curved shapes

Abstract

A system that interprets a given three-view engineering drawing and reconstructs 3-D solid models with curved shapes is described. The solid object is confined to the 3-D sheet metal object composed of planes and cutting faces consisting of lines and arcs. B y giving the high priority to the cutting faces of the 3-D sheet metal object in the operation of the combinatorial search of faces, we can reduce the reconstruction processing time. It is shown that 3-D scenes can be successfully reconstructed by the proposed algorithm and the eficiency of understanding system is also proved by experiments.
