   大家也可以提供一些相关的资料，我们来论坛就是来学习，或者帮助别人，或者于求别人的帮助！呵呵，希望大家能够互相交流交流！

Answer 1

你一定要有AutoCAD的关于DXF格式的资料，DXF是文本文件，它每一行代表什么要弄清楚才行，（我原来公司有人做过）。至于文件读取，如楼上，CStdioFile一行行地读就行了。

这此基本够你用的了
1，(设已正确打开开文件ofstream fout )
写文件头一部分：
fout<<"  0"<<endl;
fout<<"SECTION"<<endl;
fout<<"  2"<<endl;
fout<<"ENTITIES"<<endl;
2,用下面的三个函数加LINE,PLINE,TERXT
3,写文件结束部分 fout<<"  0"<<endl;
fout<<"ENDSEC"<<endl;
fout<<"  0"<<endl;
fout<<"EOF"<<endl;
fout.close();================================void COOPFEView::DXFLine(ofstream &fout, double dX, double dY, double dX1, double dY1)
{
fout<<"  0"<<endl;
fout<<"LINE"<<endl;
fout<<"  8"<<endl;
fout<<"0"<<endl;
fout<<" 10"<<endl;
fout<<dX<<endl;
fout<<" 20"<<endl;
fout<<dY<<endl;
fout<<" 30"<<endl;
fout<<"0.0"<<endl;
fout<<" 11"<<endl;
fout<<dX1<<endl;
fout<<" 21"<<endl;
fout<<dY1<<endl;
fout<<" 31"<<endl;
fout<<"0.0"<<endl;
}void COOPFEView::DXFText(ofstream &fout, double dX, double dY,double dHeight,double dAngle, CString sText)
{
fout<<"  0"<<endl;
fout<<"TEXT"<<endl;
fout<<"  8"<<endl;
fout<<"0"<<endl;
fout<<" 10"<<endl;
fout<<dX<<endl;
fout<<" 20"<<endl;
fout<<dY<<endl;
fout<<" 30"<<endl;
fout<<"0.0"<<endl;
fout<<" 40"<<endl;
fout<<dHeight<<endl;
fout<<" 41"<<endl;
fout<<0.8<<endl;
fout<<" 50"<<endl;
fout<<dAngle<<endl;
fout<<"  1"<<endl;
fout<<sText<<endl;
}void COOPFEView::DXFPline(ofstream &fout, double dX, double dY, double dX1, double dY1,double dWidth)
{
fout<<"  0"<<endl;
fout<<"POLYLINE"<<endl;
fout<<"  8"<<endl;
fout<<"0"<<endl;
fout<<" 66"<<endl;
fout<<"1"<<endl;
fout<<" 40"<<endl;
fout<<"0.0"<<endl;
fout<<" 41"<<endl;
fout<<"0.0"<<endl;
fout<<"  0"<<endl;
fout<<"VERTEX"<<endl;
fout<<"  8"<<endl;
fout<<"0"<<endl;
fout<<" 10"<<endl;
fout<<dX<<endl;
fout<<" 20"<<endl;

fout<<dWidth<<endl;
fout<<" 41"<<endl;
fout<<dWidth<<endl;
fout<<"  0"<<endl;
fout<<"VERTEX"<<endl;
fout<<"  8"<<endl;
fout<<"0"<<endl;
fout<<" 10"<<endl;
fout<<dX1<<endl;
fout<<" 20"<<endl;
fout<<dY1<<endl;
fout<<"  0"<<endl;
fout<<"SEQEND"<<endl;
fout<<"  8"<<endl;
fout<<"0"<<endl;
}
