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   
- M) L+ q2 r5 \, J4 J" V; `Dim newCenterPt(0 To 2) As Double   
Dim radius As Double        
' Define the initial center point and radius for the circle   
; r' b) \3 B( @# v- |% ]currCenterPt(0) = 20: currCenterPt(1) = 30: currCenterPt(2) = 0   
' m# P; e: x0 e& B" o; Pradius = 3        
& J3 t% }1 q5 D1 |% S+ w- ]  }' Create the circle in model space   
Set circObj = ThisDrawing.ModelSpace.AddCircle(currCenterPt, radius)   
ZoomAll   
9 d0 n/ E% K% ?3 jMsgBox "The center point of the circle is " & currCenterPt(0) & ", " & currCenterPt(1) & ", " & currCenterPt(2),vbInformation, "Center Example"   
' Change the center point of the circle   
newCenterPt(0) = 25: newCenterPt(1) = 25: newCenterPt(2) = 0   
/ u9 f, {  h6 B9 U3 p6 s5 X& m& ZcircObj.center = newCenterPt   
circObj.Update        
' Query the results of the new center position   
' Notice the output from the center property is a variant   
Dim centerPoint As Variant   
+ b3 C% R9 X9 \% R. ocenterPoint = circObj.center   
MsgBox "The center point of the circle is " & centerPoint(0) & ", " & centerPoint(1) & ", " & centerPoint(2),vbInformation, "Center Example"
# X) m4 V; {" k3 A9 i. [- x# |5 v; pEnd 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
   % W' W! [% |7 K& k: S
3.     FT(0) = 0: FD(0) = "Circle"
   
4.     Set SS = ThisDrawing.SelectionSets.Add("SS")
   
5.     SS.Select acSelectionSetAll, , , FT, FD
   + n/ q: t5 H* n4 O5 E
6.     If SS.Count > 1 Then
   0 m) t* {! D; S2 X& g1 l
7.         For I = SS.Count - 1 To 1 Step -1
   
8.             Set C1 = SS.Item(I)
   % s9 ]- W7 O* Q8 F% J2 X
9.             For J = I - 1 To 0 Step -1
   % g: i4 U+ M& I- M. k
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
    ( t% v" l/ u8 i# x9 ~6 m' }6 T2 D6 J
12.                     C1.Delete
    
13.                     Exit For
    0 M$ Z8 V5 o2 W! D3 y: Z
14.                 End If
    
15.             Next
    
16.         Next
    
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
