This paper introduces an approach to synthetize new CAD assemblies from
existing STEP files. The algorithm first generates linkage graph by detecting linkage
between components. Then it detects linkages similarities between components of
different assemblies while analyzing the associated graphs. Finally, it exchanges the
similar components. The similarities in a family of components must be formalized
by the user. Then the similar components can be replaced by the other through smart
placements. This method allows to automatically generate a wide variety of new
consistent assemblies sharing the same semantics, in order to create databases of
CAD assemblies ready for machine learning applications. It has been validated on
several cases.
