STEP實施步驟 l 分析作業流程，建立AAM(Application Activity Model) l 分析資料結構，建立ARM(Application Reference Model) l 將ARM轉換為AIM(Application Interpreted Model)

Example part information in STEP Product Structure - Components - Assemblies - Sequence Materials - Composition - Test Conditions Contexts - Coordinate systems - Transformations Product Information - Part number - Designer - Owner Topology - Loops - Shells Presentation - Display details - Interrelationships Geometry - Edges - Surfaces - Solids

Using STEP - Product Data Sharing Analysis Process Planning Manufacturing STEP DATA BASES Design Manufacturing Equipment Programming Maintenance

STEP Implementation Levels l Level 1 (File Exchange) - Transfer of passive files; specialized translators l Level 2 (Working Form Exchange) - Use of in-memory working files; - Applications share parsers, query mechanisms l Level 3 (Shared Database) - Applications request only required data from logically centralized database l Level 4 (Knowledge Base) - Object Oriented data paradigm - Constraints/behaviors embedded in data
