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.

! i6 ~! c0 o5 p) U: \) ^! F& f2 z
Dim SS As AcadSelectionSet, FT(0) As Integer, FD(0) As Variant, C1 As AcadCircle, C2 As AcadCircle, I As Long, J As Long
) k# k: a' S- v2 C7 z
FT(0) = 0: FD(0) = "Circle"
. u2 E8 A/ R* Q% X
Set SS = ThisDrawing.SelectionSets.Add("SS")
/ w4 b; S/ V Z1 i2 V
SS.Select acSelectionSetAll, , , FT, FD, Z% I* s& ~' b! e' q/ i
If SS.Count > 1 Then4 N( u, N9 J5 d% ^" X) I0 s
For I = SS.Count - 1 To 1 Step -1& ]5 R8 J: b1 Y
Set C1 = SS.Item(I)
! O" S/ C! L( R/ E- p- }8 y
For J = I - 1 To 0 Step -1
7 w- j6 C. L6 {9 J) g M
Set C2 = SS.Item(J)
: ]# H, W6 z; c. y# R' {* z
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 Then3 ~# S7 a3 M0 j* F) U
C1.Delete
+ l$ P5 x9 C9 s+ o8 r3 A
Exit For% m8 b( W, s! t$ G" C8 T7 B
End If

Next

如果好了的话楼主将怎样删除线的命令一起研发下吧
