The product data exchange between heterogeneous CAD and PDM systems is a cr
ucial issue for the integration of product development systems. STEP offers
an efficient mechanism of product data exchange between heterogeneous syst
ems. This paper introduces a UML-based mapping methodology fur the product
data models. The suggested mapping method has been applied to exchange the
product structure data between a CAD system and a PDM system. Based on the
STEP methods, we developed an interface module. (C) 2001 Elsevier Science L
