有人会CAD的VBA编辑吗？

绯村剑心

我这里有2个三维模型需要用VBA来编写，有哪位高手会的？

要用CAD里面的宏（VBA）来编辑出上面的图？尺寸都在上面有了~！
有谁会做的啊？

正在学，现在做不了，呵呵

没人高手会的吗？
有在上海的可以当面支付报酬！

第二个图形出不来,可能是因为你的CAD版本太老了吧?
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
# |' N& X% E$ `) ^7 ?9 l! g0 e

1.

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

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.
0 o# H4 I9 C8 ]; ^6 r% k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

1. 
   
2. ThisDrawing.SendCommand "plan c ucs w -shademode g "
   ' ^# C0 S5 u  [/ C7 o4 y3 D

复制代码

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.

恩~！我刚又试过你11楼的后面代码的2个图型都出来~！ 真是太感谢你了！
想自己再研究下你写的代码，就是实在看不懂啊~！
