summary One of the principal tasks of history based parametric modeling is to maintain the design history of parts. When some constrains or definitions of a feature on the part aremodified, it should be guaranteed that its design history could be replayed automatically and correctly. Thus the users can get the desired part expediently, quickly andunambiguously. Topological naming mechanism is one of the main important technologies to fulfill this task. In order to solve this problem, this paper first analyzes thedesign history of parts, then presents a face based mechanism for naming, recording and retrieving topological entity and finally proposes a method named parametricspace information to solve ambiguity when recording and retrieving entities. This mechanism, which provides a solid basis for replaying the design history precisely, hasbeen implemented in InteSolid, a history and feature based modeling system.
