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"
' Change the center point of the circle
newCenterPt(0) = 25: newCenterPt(1) = 25: newCenterPt(2) = 0
circObj.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
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.

+ J ~4 x! M! P9 E& D7 [
Dim SS As AcadSelectionSet, FT(0) As Integer, FD(0) As Variant, C1 As AcadCircle, C2 As AcadCircle, I As Long, J As Long
5 o K7 D. Y. |! J7 V. k# v: q
FT(0) = 0: FD(0) = "Circle"1 Y+ d2 \7 L" O% v
Set SS = ThisDrawing.SelectionSets.Add("SS")
- B% _1 g4 L# R9 |5 I
SS.Select acSelectionSetAll, , , FT, FD& F5 v0 O& _& d/ N' |
If SS.Count > 1 Then: [. @4 H% Y% x6 g, H2 U1 {
For I = SS.Count - 1 To 1 Step -1
; G4 _6 ~9 [! x: b; d# h
Set C1 = SS.Item(I)
+ W# V% {( L# O! x, [5 a
For J = I - 1 To 0 Step -17 {4 A$ v) I3 N3 K: _
Set C2 = SS.Item(J)
6 ?+ n8 w5 z) c7 p
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* T7 z- e' U; X, H! u( @- ^3 H6 w
C1.Delete
4 G' N% f/ _, Q+ S0 d
Exit For

如果好了的话楼主将怎样删除线的命令一起研发下吧
