【摘要】 本论文对目前的多种图档管理技术进行了具体深入的研究，结合工程图样数据的特点，借鉴PDM系统管理图档的思想，设计开发了一套基于AutoCAD2000平台的工程图档管理系统。 论文所作的工作包括以下几个方面： 第一，在对各种图档管理技术进行研究的基础上，提出了采用元数据对象管理技术管理工程图样的总体思想，并对以面向对象、面向设计过程、动态管理为核心的基于AutoCAD 2000平台的工程图档管理系统的总体结构方案进行了设计。 第二，对工程图样数据的特点进行了深入研究，分析了图档管理过程中的数据流向，并在对PDM系统图档管理思想进行探讨的基础上，采用关系型数据模型，建立了动态图档信息库。 第三，深入研究了相关的工程图样技术，通过对工程图档间的联系及图档内容间的关联的分析，确定了关联对象的模型，并实现了图档文件内、图档文件间对象的相关定义及修改自动提示。 第四，通过对图样共性的研究，开发了一组AutoCAD内嵌模块，实现了标题栏、明细表等图纸公共对象的自动绘制与插入。 第五，在上述研究的基础上，编制了相应的软件系统，建立了系统的体系结构、运行机制与接口，确定了系统的主要功能，完成了系统功能的分解及各功能模块的设计。 通过对系统集成和调试，最终形成了一套基于AutoCAD的工程图档管理软件系统，基本解决了AutoCAD生成的工程图档及其属性信息的管理问题，减少了信息的重复录入，提高了工程图档的重用性，实现了安全、动态的图档管理。更多还原

【Abstract】 In the dissertation, the application of drawing files management technique and characteristics of the engineering drawings are analyzed. The general structure,integrated frame and information model about the integrated software system------"Engineering drawing files management system based on AutoCAD 2000" are researched.The main contributions are included as follows:The first, Meta-data technique is introducted into the field of drawing files management, and the overall structure scheme of "Engineering drawing files management system based on AutoCAD 2000" is proposed.The second, the idea of PDM is discussed. Through analyzing the data of engineering drawings and the data flowing in drawing files management process, the dynamic drawings information database is bulit after setting up the information model.The third, the simple relation model of drawing objects is developed. After studying the relations in drawing files and between files, the objects’ relation definition and modification in files and between files are brought out.The fourth, some programme modules of AutoCAD 2000 are designed to draw the forms in the engineering drawings automatically.The fifth, the function of every module is defined after the integrated system is detached based on the characteristic of files management. All the modules are integrated by means of closed integration, and an integrated software system is formed which has friendly interfaces and simple operation.By debugging system, the integrated software system------"Engineeringdrawing files management system based on AutoCAD 2000" is bulit. The main problem of files and files’ information management is solved by using the software system, and a valid means is provided for managing drawing files securly, improving the quality of products design and decreasing time of modifying design更多还原
