The sequence for an assembly design must be exhaustive and validated during the design process quickly to facilitate decisions made during the design process. To meet this requirement, it is essential to develop tools for generating assembly sequences. The effectiveness of an Assembly plan depends more on the way, the assembly is modeled. Using design tools, it’s easy to planout the skeleton of the assembly, so that individual components can be designed in the context of the overall structure.As a result, the complexity of managing various relationships between components is simplified. This paper presents a method, to assist the generation of relationships among parts of the assembly using ProToolkit objects that reflects the Pro Engineer Database. By visiting the geometric objects in a solid model, the Object Handles of all the geometric objects can be acquired. This paper also presents different applications in theAutomaticAssembly domain using the geometric modeling system as a basis.
