Parametric CAD Data Exchange Using Geometry-Based Neutral Macro File.

Recently, CAD data translation without loss of design intend using commercial CAD data Translators is still impossible because these systems do not have creation history and modification history of feature. Macro parametric methodology is suggested as a solution of this problem, but critical problem still remains. The reason of this problem is that topology-based macro can cause an ambiguity in the name of feature. In this research, geometry-based neutral macro methodology is suggested as a solution of this problem. [ABSTRACT FROM AUTHOR]
