第二个图形出不来,可能是因为你的CAD版本太老了吧?
4 k- q6 P J: i Z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
4 J0 m+ A$ b# a0 \, A9 H- & z8 c& O6 r( J2 p% p2 p: D3 g% V- t

3 c/ P0 C& \/ ~3 b; P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.
D* i |2 O, V Y( q# @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
6 f+ g! e' e/ z( |. a+ I

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.& \4 g* P; J3 t# {
