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：
2 n4 D, j( D. B' t- TSub Example_Center()        
Dim circObj As AcadCircle   
# l' k+ I; l! QDim currCenterPt(0 To 2) As Double   
  S0 D  I0 ^' \% W, @$ V) |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   
8 r2 |6 ?3 I$ m9 h. {radius = 3        
' Create the circle in model space   
, h/ G4 m4 ~8 Y1 m; w8 q+ U  ~Set circObj = ThisDrawing.ModelSpace.AddCircle(currCenterPt, radius)   
ZoomAll   
0 W% w$ X: P# g1 L) }MsgBox "The center point of the circle is " & currCenterPt(0) & ", " & currCenterPt(1) & ", " & currCenterPt(2),vbInformation, "Center Example"   
  ^: v1 t4 b: G- [5 F' Change the center point of the circle   
% q# [! M" g) lnewCenterPt(0) = 25: newCenterPt(1) = 25: newCenterPt(2) = 0   
6 z% ~! }5 N) {" o$ z/ T! KcircObj.center = newCenterPt   
- a, R7 j* B- LcircObj.Update        
' Query the results of the new center position   
' ^4 @- q( P$ Q4 ?$ d' Notice the output from the center property is a variant   
Dim centerPoint As Variant   
. m* Q! b- V! x- mcenterPoint = circObj.center   
: R" Y' _$ R, J* W' ]MsgBox "The center point of the circle is " & centerPoint(0) & ", " & centerPoint(1) & ", " & centerPoint(2),vbInformation, "Center Example"
3 N4 r! r, t7 r. L, mEnd Sub

圆心(点)是数组,得分别比较三个坐标才行.

1. 
   . |( d& m5 [  o. z" f
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"
   # f" ?7 u+ f* j+ G( l
4.     Set SS = ThisDrawing.SelectionSets.Add("SS")
   : s4 M8 A- {% |' G
5.     SS.Select acSelectionSetAll, , , FT, FD
   
6.     If SS.Count > 1 Then
   
7.         For I = SS.Count - 1 To 1 Step -1
   0 y. N) h1 \9 w4 A9 u# {$ d
8.             Set C1 = SS.Item(I)
   
9.             For J = I - 1 To 0 Step -1
   6 [& f5 g, ~4 U3 R1 a' @5 H
10.                 Set C2 = SS.Item(J)
    / }; Q1 E% f9 b: g3 c& @: `
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
      i! A# f% e) F7 r
12.                     C1.Delete
    
13.                     Exit For
    * w; d$ ^. c0 X! ^! }
14.                 End If
    
15.             Next
    * F3 C  N1 h- m
16.         Next
    / C5 @8 H! `; J* C
17.     End If
    
18.     SS.Delete
    . `/ p/ V6 S- `$ ?( N7 S

如果好了的话楼主将怎样删除线的命令一起研发下吧
