Virtual environments (VE) are becoming an important tool for simulating man
ufacturing systems. A problem in their adoption is the lack of an easy and
effective approach to building large and complex virtual environments that
are required by many manufacturing simulation tasks. This paper reports on
research into this problem and presents a novel approach-domain-analysis-ba
sed top-down construction-to constructing complex virtual manufacturing env
ironments. Based on this approach, a software system is designed and implem
ented to provide easy-to-use and flexible tools that enable users to constr
uct virtual environments rapidly and with minimum modelling effort.
