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；
# g' R: N+ _2 H4 }# {0 }5 Ecircle对象的center属性示例代码如下：
Sub Example_Center()        
Dim circObj As AcadCircle   
$ A* D! b- o  x" n% a/ vDim currCenterPt(0 To 2) As Double   
: {! a( J8 @' Z& u( J# QDim newCenterPt(0 To 2) As Double   
  k: x: r) V- K8 y( ]* jDim radius As Double        
' Define the initial center point and radius for the circle   
& \7 w! j8 A7 M& u4 x, scurrCenterPt(0) = 20: currCenterPt(1) = 30: currCenterPt(2) = 0   
radius = 3        
: f7 _& L2 C& j" A; P4 Y' Create the circle in model space   
$ W( N5 V+ d* z1 n' \( [2 VSet circObj = ThisDrawing.ModelSpace.AddCircle(currCenterPt, radius)

MsgBox "The center point of the circle is " & currCenterPt(0) & ", " & currCenterPt(1) & ", " & currCenterPt(2),vbInformation, "Center Example"   
* h) F& O9 I) v3 o/ |# q+ _# a' Change the center point of the circle   
newCenterPt(0) = 25: newCenterPt(1) = 25: newCenterPt(2) = 0   
circObj.center = newCenterPt   
4 \  B8 l2 P  A! n% g6 `circObj.Update        
' Query the results of the new center position   
' Notice the output from the center property is a variant   
Dim 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. 
   
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.     FT(0) = 0: FD(0) = "Circle"
   
4.     Set SS = ThisDrawing.SelectionSets.Add("SS")
   / d" \- J, v8 K, i0 n: f9 a- ]
5.     SS.Select acSelectionSetAll, , , FT, FD
   * D7 r: D" }$ O% @2 a6 E7 }
6.     If SS.Count > 1 Then
   , t: p% `5 Q8 G
7.         For I = SS.Count - 1 To 1 Step -1
   
8.             Set C1 = SS.Item(I)
   
9.             For J = I - 1 To 0 Step -1
   ; p% T# E* H  p0 N( x  U3 m: d
10.                 Set C2 = SS.Item(J)
    5 Q& h' {# l/ i* @
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
    
12.                     C1.Delete
    % t: r1 f1 U& m: l
13.                     Exit For
    
14.                 End If
    
15.             Next
    
16.         Next
    ( ~- f6 g3 p. y* F0 E& H, Y/ }, D( z
17.     End If
    
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
