In an assembly environment, explicit interface information between the major part components is necessary to determine proper assembly plans, avoid undesirable interferences between parts, and achieve the required product function. A semantic association model (SAM*)-based assembly database is proposed to organize this assembly-specific semantic information in a hierarchical structure in its subassembly module. A hybrid constructive solid geometry/boundary representation (as a structured face adjacency graph) is used to represent each component part of the assembly. These are stored in single part modules. The representational scheme is feature based and a functional relationship graph is developed to establish the required mating conditions between these features of different components in an assembly.
