在整體工程管理科技之中，產品資料管理佔了極為重要的角色。而在所有作業流程之中，生產自動化和同步工程為降低成本及品質保證的成功關鍵，無論在設計分析、生產管理或後勤支援等各層面，資料庫化、資料轉換在整體製造過程或同步工程的應用上即成為一個重要的工作。電腦輔助設計與製造或電腦整合製造在一般工業及航太工業的使用上已漸成為一不可或缺的工具，但是在目前工業界廣泛使用之不同的應用軟體與作業平台之中的資料轉換雖有國際標準的格式加以規範，但在實際使用上仍有其匱乏之處，而對於電腦實體模型資料轉換的錯誤即意味著必須要花更長的時間與人力和更多的成本來修正資料的錯誤。
本論文主要探討多種航太工業習用之電腦輔助設計製造軟體，如CATIA V5、SolidWorks和AutoCAD的資料傳送與交換的關聯性，並探討各應用軟體對於物件特徵的描述、定義及相容性。如此可協助設計人員在資料轉換的處理程序之中，作一先前的完整系統規劃，進而維持物件資料的完整以利後續的製造、物料管理、成本分析等整體企業資源有效利用，以達成航太工業之電腦整合製造的最大效益。

Computer aided technologies exist for virtually every task in the design and manufacturing process, especially for modern aerospace industry. Among all the computer-aided tools recently developed, data management plays a very important role in the integrated engineering management systems. For continuous improvement and lower the cost, using automatic production technology and concurrent engineering is the key role to success. CAD/CAM is the name often given to computer aided tools that assist in the design and manufacturing processes. However, even the data transfer standard such as STEP/IGES have been well developed for a decade, the data transfer between different platform and software still the major risk for general industry.
This work conduct a systematic investigation about the engineering database communication problems among the common used CAD/CAM software in aerospace industry such as CATIA version 5, SolidWorks and AutoCAD. This project also discusses the differences about entity’s characteristic and definitions had been described between different software. This study will try to realize those existing data transfer problems and to reduce the overall cost for aerospace industry.
