This paper introduces a two-stage approach that automatically generates 3D CAD models from 2D
orthographic drawings. First, a pattern-matching algorithm is proposed to reconstruct a network of
3D edges by matching 2D edge features extracted from the multiple views of the 2D drawing. Second,
starting from the resulting 3D wireframe and generated graph, a loop detection algorithm allows
identifying possible loops of faces. Then, a clustering algorithm recognizes the faces from the set of
detected loops. The reconstruction ends while trimming and stitching the faces to get a watertight
ready-to-use 3D CAD model. This approach has been validated on a public dataset composed of several
thousands of 3D shapes, and it achieved 99.59% of well-reconstructed models in F-score.
