Reverse Engineering Of Autocad Fonts, Linear Study

With the rapid developing of computer and information technology,it is becoming more and more important that the data transferring,interchanging,sharing,processing of the CAD production. At present,it is the virtual standard of CAD data memory technology that the DWG memory formation of AutoCAD of AutoDesk corporation in USA. But AutoDesk corporation always keeps secret the DWG memory technology,which is paradoxical to the rapid developing of information technology,therefore,under the guidance of OpenDWG alliance headed by the Visio corporation USA,it is flourish developing that the AutoDesk reverse project aiming to code the DWG formation.The main content in this paper is to realize font and line type in the AutoDesk reverse project,and in this paper it is being dissertated that correctly readable DWG file data of AutoCAD,based on classes library,facing AutoCAD reverse project,using the method orient to object programming .software to design software,and it is realized that the software system of font and line type in the DWG picture.
