基于DXF技术的草图绘制软件设计与实现
摘要：
DXF是Autodesk公司开发的用于AutoCAD与其它软件之间进行CAD数据交换的CAD数据文件格式，是一种基于矢量的ASCII文本格式。
基于DXF技术的草图绘制系统就是要实现基本草图的绘制和编辑功能，并且能够将所绘制的草图以DXF文件格式保存到存储器或者数据库，从而使其它支持DXF格式的CAD软件能够将其打开和进行二次开发，此草图绘制系统还能打开标准的DXF格式的文件并对其进行二次开发。
本课题主要研究利用基于VS2005的C#语言所提供的GDI+绘图技术及AutoCAD所开发的DXF技术，实现各种基本工程草图的绘制功能，并在此基础之上实现对草图的DXF格式的计算机存储、读取和各种编辑功能。课题工作主要分为三个部分：第一部分是搭建系统架构，设计绘图系统的操作界面；第二部分是设计基本草图的绘制方法，实现基本草图的绘制和编辑功能；第三部分是设计和实现基于DXF技术的基本草图的存储和读取机制。

Title Graphics Drawing Software Design and Implementation
Based on DXF Technology
Abstract
DXF,developed by Autodesk Company,is a CAD data file format and a vector-based ASCII text format,and it usually used for data exchange between AutoCAD and other CAD software.
This system is aimed to achieve some basic functions of drawing and editing various on this system,the graphics can be drawn and edited on the screen and can be saved as DXF format files in database or memory,so that graphics can be recognized by other DXF format supported CAD software and also can be used as a secondary development. In addition,the system can also read standard DXF format files, using them for secondary development.
The main subject of this study is to achieve the drawing,storage,reading and editing of a variety of basic graphics by the GDI+ provided by Microsoft’s C # language and the AutoCAD DXF technology,and all tasks are completed in the VS2005 project is mainly divided into three parts: The first part is to build the system architecture,design the system interface according to the mission statement;The second part is the design of the methods of drawing and edi
