VBA怎样删除重复的圆？

taqqug

弱弱的问一下大家，CAD中怎样用VBA标记出有重复的圆，并提示删掉？我现在用选择集选择了所有的圆，想用圆心相等来判断（还得半径相等），可是圆心不让比较，请大家帮忙，最好给出代码，谢谢啦！！

circle对象的center属性返回的是一维三元素数组，0代表圆心的x坐标，1代表圆心的y坐标，2代表圆心的z坐标，可以分别通过比较x、y、z坐标判断圆心是否相同，注意控制坐标值的对比位数；
circle对象的center属性示例代码如下：
Sub Example_Center()        
Dim circObj As AcadCircle   
Dim currCenterPt(0 To 2) As Double   
Dim newCenterPt(0 To 2) As Double   
Dim radius As Double        
' Define the initial center point and radius for the circle   
currCenterPt(0) = 20: currCenterPt(1) = 30: currCenterPt(2) = 0   
radius = 3        
' Create the circle in model space   
Set circObj = ThisDrawing.ModelSpace.AddCircle(currCenterPt, radius)   
ZoomAll   
MsgBox "The center point of the circle is " & currCenterPt(0) & ", " & currCenterPt(1) & ", " & currCenterPt(2),vbInformation, "Center Example"   
  ?1 Z3 A4 O" c! d  r% m' Change the center point of the circle   
' E( O$ O) ^  k0 \# E0 AnewCenterPt(0) = 25: newCenterPt(1) = 25: newCenterPt(2) = 0   
circObj.center = newCenterPt   
$ J/ R. c& R- U1 w# u4 \' Z; vcircObj.Update        
0 |( e" c% p# j( m# e' Query the results of the new center position   
* Y$ _  g) C; c4 e7 ^) A' Notice the output from the center property is a variant   
* V3 `+ P+ S8 Q1 fDim centerPoint As Variant   
centerPoint = circObj.center   
MsgBox "The center point of the circle is " & centerPoint(0) & ", " & centerPoint(1) & ", " & centerPoint(2),vbInformation, "Center Example"
End Sub

圆心(点)是数组,得分别比较三个坐标才行.

1. 
   - ^$ y2 _2 J, `& j1 Z, M
2.     Dim SS As AcadSelectionSet, FT(0) As Integer, FD(0) As Variant, C1 As AcadCircle, C2 As AcadCircle, I As Long, J As Long
   3 ?0 [6 s/ _+ [0 }- Q% A3 _, d( B
3.     FT(0) = 0: FD(0) = "Circle"
   
4.     Set SS = ThisDrawing.SelectionSets.Add("SS")
   
5.     SS.Select acSelectionSetAll, , , FT, FD
   
6.     If SS.Count > 1 Then
   
7.         For I = SS.Count - 1 To 1 Step -1
   
8.             Set C1 = SS.Item(I)
   * _4 I# p6 [. r
9.             For J = I - 1 To 0 Step -1
   
10.                 Set C2 = SS.Item(J)
    
11.                 If C1.Center(0) = C2.Center(0) And C1.Center(1) = C2.Center(1) And C1.Center(2) = C2.Center(2) And C1.Radius = C2.Radius Then
    6 P* D3 S# v+ @5 s0 E
12.                     C1.Delete
    
13.                     Exit For
    . |3 b* f- Z( b. q0 w8 F
14.                 End If
    $ e! b4 v6 m' C5 @+ V9 e
15.             Next
    
16.         Next
    + P) A5 {' T5 P. O9 @' o
17.     End If
    , Y: W; U% S! O5 A. g% P
18.     SS.Delete

如果好了的话楼主将怎样删除线的命令一起研发下吧
