In this paper, an algorithm is presented for reconstruction of the 3D entities from three viewgraphs of machinery parts based on the mechanical three viewgraphs and its IGES files output from AutoCAD. The key techniques for information pre-treating, reconstruction of 2D loops and 3D entities are discussed in detail step by step. During reconstructing the 2D loops, the objects to be treated are points of intersection instead of lines and arcs. Boolean calculation is used to shape 3D entities. At the end of this paper, the reliability of the algorithm is testified by an experiment.
