This paper describes a theory and application of a manifold-based hierarchical non-manifold model. A local restoration function, which restores only the areas concerning with a specified part in the reverse sequence of the operations, is desirable to cope with design changes. It is realized on a manifold-based hierarchical non-manifold model, which is implemented into a computer system with a "dead shell method." A boundary edge created by a set-operation or filleting, and its adjacent face has a relation to an edge of a dead shell, which is a "lost" or hidden shell created by operations. A "live shell" and "dead shells" comprise a hierarchical non-manifold as a whole. This method has been proved to be useful in practical use.
