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