A feature interface model towards distributed solid modeling

Feature is the fundamental design unit in modern solid modeling systems, and this makes a well defined feature interface a matter of concernment in the component based distributed modeling environment. This paper introduces a feature based modeling service framework and proposes an interface model of feature based modeling service toward such a modeling environment, including support of remote feature attachment and semantic maintenance. A prototype based feature interface definition strategy using procedural attaching and declarative validation mechanism is discussed and how the interface model tackles with the problems in distributed environment, such as locality transparently model reusing, is also explained.
