The reconstruction of 3D objects from 2D orthographic views is very important for the maintenance and continued development of existing product designs. An efficient method for generating 3D curvilinear wire-frames from three orthographic views is presented, which is the pivotal stage of solid reconstruction by wire-frame-oriented approaches. By unifying the recovery of spatial conics without restrictions on their positions, our method can improve the efficiency and reliability of curvilinear wire-frame reconstruction. A projection matching algorithm is proposed to efficiently reveal all match projections according to the projective properties of spatial edges. Furthermore, a four-point method, which is based on the rational Bézier form of conics, is proposed to uniformly generate various types of conics in arbitrary positions. Several examples are provided.
