Relating functional schematics to hierarchical mechanical assemblies

This paper presents the concepts necessary to link mechanical designs and functional schematic diagrams. Like mechanical designs, schematic designs involve a hierarchy of reusable systems. In addition they add the concept of system-to-system connections. The approach described in this paper maximizes design reuse by making the associations at the lowest, possible assembly level. Too often this type of engineering data is either not captured or is duplicated for different design variations. This leads to the serious configuration control problem of keeping multiple copies of common design information synchronized. Redundant copies of design data lead to unnecessary manual effort, at best, and incorrect design data at worst.
