STEP(Standard for the Exchange of Product model data:製品モデルデータ交換の国際規格)の造船関係の規格制定の動きについて
The basic strategy of the STEP community is to create a set of "application protocols (APs)" that convert end-user requirements into specifications that can be used to test conformance of vendor implemented application software (i.e. configuration control of design data) to the standard. The APs define the scope (using an activity model), the information to be exchanged (using an information model), the means of testing (using test suites), and a users guide for implementing the application.
Design Intent Information Exchange of Feature-Based CAD Models
Modern feature-based CAD system can represent design intent with construction history, feature, parameterization and constraints. Until recently, standards for CAD data exchange among different CAD system were restrict to the exchange of pure geometrical information. This paper discusses the contents, formalization and characteristics of design intent of feature-based CAD models and the information exchange mode in detail. The problems of representing and exchanging the information of design intent are also discussed. An approach to mapping design intent information among CAD system is presented. According to the newly published parts of the International Standard ISO 10303, A XML neutral format of information exchange model is presented.
