第二个图形出不来,可能是因为你的CAD版本太老了吧?
( |; f. \3 M0 x- l' e在早期CAD中,LWPolyline(二维多段线)对象使用三维坐标,而现在常见的版本中该对象已经优化,改为使用二维坐标.7楼代码就是用二维坐标设计的.如果在早期版本中运行该代码,应该把多段线顶点坐标数组改为三维的形式,如下
9 ~% i; \$ i; y T+ h9 B- , l: ~1 O& @7 F: v2 J+ [

如果要求程序运行的最后得到像1楼附图一样的显示结果,可以给三维实体赋予指定的颜色,并调用图形界面的"着色"命令改变视图的显示模式.还可以改变视图方向,如下2 Q8 {! n/ }& h1 B7 ^4 K( B: d

上面代码中宏"A"和"B"分别是画1楼两个图形的代码."MyDisplay"是供两个宏运行到最后调用的子程序,用于修改视图方向和修改视图为"体着色"模式.
) u& r- V) n8 z4 }, ^由于CAD2007以上版本中,"shademode"命令已被改为调用"视觉样式"命令,所以,如果在2007以上版本中运行本代码,应把ThisDrawing.SendCommand "plan c ucs w shademode g "一行,改为

- ThisDrawing.SendCommand "plan c ucs w -shademode g "

请注意,新的代码中,第二个图形中的多段线仍然使用的是二维坐标,如果在早期版本中使用,应按前面所说的方法修改.
