有资求助！
本人要在CAD里面弄一个画缓和曲线的ARX程序，源代码已经有了。但是对于ARX及VC++不了解，所以想请哪为高手帮忙！最好是已经编译好的了。谢谢！<P class=MsoNormal style="MARGIN: 0cm 0cm 0pt; TEXT-INDENT: 24pt"><FONT face="Times New Roman">AcDbObjectId CreateArc(AcGePoint3d center,double r,double starangle,double endangle)<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" /><o:p></o:p></FONT>
