Based On The Autocad2000 The Engineering Document Management System

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...
