Reverse engineering is more than just scanning a part being removed from service.  For production procurement, the reality is that a detailed Technical Data Package (TDP) needs to be defined for the part.  The TDP defines the part’s complete set of technical requirements, including the 3D and 2D geometry, tolerances, materials, special manufacturing processes, specifications, etc.  As importantly, it’s not only essential to have the content of the complete part TDP for production and first article inspection, but it’s also critical to have it in a proper format from major CAD tools.  This format enables the model based enterprise for tracking of requirements and results throughout the product realization lifecycle.
