龙大哥的程序没有考虑内容有封闭区域的情况，所以用默认的使用多段线在内容有封闭区域时是不会成功的。应使用面域。
林大哥的程序只对过滤器中的几种对象有效，可能对于椭圆来说变成多段线的工程会大点。
(defun outline()
(setq aa (ssget "x"))
(command "_.region" aa "")
(setq set1 (ssget "x"))
(setq n (sslength set1))
(while (/= n 1)
(progn
(setq a 0)
(setq tu_1 (ssname set1 a))
(setq tu_2 (ssname set1 (1+ a)))
(command "_.union" tu_1 tu_2 "")
(setq set1 (ssget "x"))
(setq n (sslength set1))
)
)
)
union不是只能是两个对象，而是可以多个对象的。所以不用那么麻烦，。。。
其实对insert spline ellipse等对象也是可以的，只是最后转成pline线的时候还需要
很多的代码来支持，有心人请帮着写写吧！
龙大哥的程序缺少屏幕缩放判断模块，屏幕跳来跳去不舒服。
怎么還沒有可以對insert spline ellipse等对象的啊? 這個程序很好的嘛.不知哪位師傅有.可以貼上來給大家分享分享嘛.謝謝啦.
lyy很有陈斑主的风格嘛!
其实只要可能性考虑的全一点就可以.
请参考“边界轮廓线程序”一帖！
