如果你有空闲来无事，帮我造一个这样的东东吧

邹锋

大家晚上好啊，我想写个，命令，框选图形，就能输出到“”D:\1.dat“里，dat 是装数据的，主要是直线，圆，圆弧，的数据，不包括其他东西，如选到除上面所述的线，不处理如果你技术高超，把这线形也转成上述三种也可，再输出它的数据
以下是DAT文件范例

C = -0.504964,70.000000,2.000000
L = -6.470663,70.000000,-0.504964,75.965699
L = 5.460736,70.000000,-0.504964,64.034301
L = -0.504964,75.965699,5.460736,70.000000

L = -0.504964,64.034301,-0.504964,75.965699
L = 5.460736,70.000000,-6.470663,70.000000
A = 70.000000,6.670663,69.808048,6.614497,70.191952,6.614497,N
A = 76.165699,0.504964,76.109534,0.696915,76.109534,0.313012,N
A = 70.000000,-5.660736,70.191952,-5.604570,69.808048,-5.604570,N

A = 65.230007,5.274956,69.808048,6.614497,63.890466,0.696915,N
A = 74.769993,-4.265029,70.191952,-5.604570,76.109534,0.313012,N
A = 65.230007,-4.265029,63.890466,0.313012,69.808048,-5.604571,N
A = 12.000000,-12.000000,12.000000,-15.000000,15.000000,-12.000000,N
A = -12.000000,-12.000000,-15.000000,-12.000000,-12.000000,-15.000000,N
A = -10.000000,10.000000,-10.000000,15.000000,-15.000000,10.000000,N
A = 10.000000,10.000000,15.000000,10.000000,10.000000,15.000000,N
L = 12.000000,-15.000000,-12.000000,-15.000000
L = -10.000000,15.000000,10.000000,15.000000
L = -15.000000,-12.000000,-15.000000,10.000000
L = 15.000000,10.000000,15.000000,-12.000000
C = 0.000000,0.000000,10.000000

由以上数据分析如下
C = -0.504964,70.000000,2.000000
;;C 代表圆  
;;-0.504964,代表圆心坐标x轴
;;70代表圆心坐标的y轴数据，
;;2代表圆半径
L = -6.470663,70.000000,-0.504964,75.965699
;;L 表示直线
;;-6.470663,70.000000为直线第一个点的坐标  
;;-0.504964,75.965699为直线第二个顶点的坐标
A = 70.000000,6.670663,69.808048,6.614497,70.191952,6.614497,N
;;;A代表圆弧  
;;;70.000000,6.670663,为圆心坐标
;;;69.808048,6.614497,表示圆弧的第一个端点
;;;70.191952,6.614497代表圆弧第二个端点，
;;;N为逆时针  
;;;圆弧第一个端点是按逆时针开始的点来确定

应该不难啊，过滤三种图元，遍历选择集的每个对象，提取相应数据就行了。

VBALISPER

嗯,这种东西还是应该自己闲来无事的时候做.

cabinsummer

简单至极，是想用在数控加工上吧？

nhbabc

用选择集过滤后，在输出到文件
