Reverse engineering is a rapidly evolving discipline, which covers a multitude of activities. In this paper we will only be concerned with reverse engineering of shape, but a broader interpretation of the term to involve understanding of design intents and mechanisms is also possible. While conventional engineering transforms engineering concepts …
