Abstract STEP (International Standard for Product Data Representation and Exchange) is considered to be a key for the integration and exchange of product models. To achieve this objective the fundamental concept of Application Protocol has been developed. The design of an Application Protocol is composed of various processes based on different techniques. This design is vast, iterative and complex. Therefore, it seems to be necessary to develop a tool assisting the design of an Application Protocol. In this paper we describe SMGS (STEP Model Generator System), a tool that gets the different application user models and gives the corresponding STEP models and verifies the uniqueness of these models. The problems encountered using the first prototype of this tool, in the crane industry’s domain are discussed. This prototype consists of three major components: user interface module, Integrated Resources mapping module and uniqueness testing module. The object-oriented methodology is used to design the user interface. With this interface, the expert of the application’s domain, with help of data dictionary built in system, can easily access to the integrated resource models of STEP and can specialize these resources.

Feature Evolution

Abstract Capturing design process is becoming an important topic of feature-based modeling, as well as in product data exchange, concurrent design, and cooperative design. Three critical issues on the modeling of design process are considered in this paper, namely, feature concepts, feature evolution, and the semantic consistencies of the states of product models. A semantics-based product model is introduced to facilitate the description of both conceptual and detailed models, and to maintain the semantic consistencies of product states. The process is represented by feature states and their evolution records. Feature type variation and prototype-based design are proposed to support feature evolution. A conceptual description of the design process and an example are given.
