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；
0 z3 F$ o! W. y# mcircle对象的center属性示例代码如下：
Sub Example_Center()        
  u# {, L4 F+ U9 o* Y# y& E! rDim circObj As AcadCircle   
Dim currCenterPt(0 To 2) As Double   
3 ^$ G+ s8 T& Z/ ^Dim newCenterPt(0 To 2) As Double   
Dim radius As Double        
' Define the initial center point and radius for the circle   
3 i6 Z5 ~( B& Q3 N3 [- E2 S: TcurrCenterPt(0) = 20: currCenterPt(1) = 30: currCenterPt(2) = 0   
radius = 3        
6 I  G' R7 R# H) B' Create the circle in model space   
Set circObj = ThisDrawing.ModelSpace.AddCircle(currCenterPt, radius)   
ZoomAll   
- P3 m  U( ~/ D6 j" \! N' TMsgBox "The center point of the circle is " & currCenterPt(0) & ", " & currCenterPt(1) & ", " & currCenterPt(2),vbInformation, "Center Example"

newCenterPt(0) = 25: newCenterPt(1) = 25: newCenterPt(2) = 0   
circObj.center = newCenterPt

' Query the results of the new center position   
' Notice the output from the center property is a variant

圆心(点)是数组,得分别比较三个坐标才行.

1. 
   . V. v+ x# E8 t
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")
   % x3 E, [( ?! H( q# C* _1 p
5.     SS.Select acSelectionSetAll, , , FT, FD
   ; W6 D8 E  k0 Z0 X. S
6.     If SS.Count > 1 Then
   + U/ g+ N6 R4 o5 b+ Z
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
   
10.                 Set C2 = SS.Item(J)
    3 |# Q8 Y) p3 F/ b$ F8 x' U* X
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
    & P6 `$ {; J0 U: A+ s
13.                     Exit For
    ' @' X9 K: |* |5 X3 w
14.                 End If
    
15.             Next
    % O0 ?9 s3 H, q
16.         Next
    / L% q- E8 f2 O1 i
17.     End If
    ' Y6 b/ ~* x: D, k* w$ G3 h  f  H
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
