Skeleton models capture and define design intent and product structure. Skeletons allow designers to pass along essential design information from one subsystem or assembly to another. This essential design information is either master definitions of geometry or copied geometry from designs defined elsewhere. Any changes made to a skeleton change its components as well.

The use of a top-level skeleton model allows you to control the following information from a central, top-level location (from the top down):

Individual skeleton models can be used to build the components from the bottom up. This method ensures a robust design with the design information communicated smoothly throughout the assembly.
