In previous work (UUCS-93-007), we have proposed a new design for inspection
and reverse engineering environments. We have investigated the use of the
dynamic recursive context of discrete event dynamic systems (DRFSM DEDS) to
guide and control the active exploration and sensing of mechanical parts for
industrial inspection and reverse engineering, and utilized the recursive
nature of the parts under consideration.  In our recent work, we construct a
sensing to CAD interface for the automatic reconstruction of parts from visual
data.  This report includes previous results and describes this interface in
greater detail, demonstrating its effectiveness with a reverse-engineered,
machined part.
