This paper discusses the issues and unsolved problems in face identification in 3D shape recovery from 2D sketches. The sketch is drawn from a single projection and is given in the form of a line drawing. Topological analysis of the drawing help identifying faces of the 3D model the sketch depicts. The face information can significantly reduce the complexity of 3D reconstruction. Imperfections in the drawing may affect the topological analysis of a line drawing. A revised methodology that can handle general objects and imperfect line drawings is discussed. Deletion and partition operations are proposed in converting a non-manifold to manifolds when the conversion is possible. A method that partitions certain complex manifold objects to reduce the complexity of 3D reconstruction is also proposed.
