我在cad命令行里加载dll,能够生成需要的图形.保存!问题出在我全部关闭cad时.cad 出现如图所示情况!.请大侠帮忙一下!谢谢!(虽然下次打开cad都没问题,但是每次都出现这样的对话框,感觉很烦人!希望高手能告知破解的方法!不胜感激!附上代码!(主要就是在当前cad 图形中加入圆,加入外部块,文字等)using System;using System.Collections.Generic;using System.Text;using Autodesk.AutoCAD.ApplicationServices;using Autodesk.AutoCAD.EditorInput;using Autodesk.AutoCAD.Runtime;using Autodesk.AutoCAD.Geometry;using System.IO;using Autodesk.AutoCAD.DatabaseServices;namespace ClassLibrary2{    public
