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.

6 E! r$ l3 Y% d! O
Dim SS As AcadSelectionSet, FT(0) As Integer, FD(0) As Variant, C1 As AcadCircle, C2 As AcadCircle, I As Long, J As Long" P$ l$ Y6 I* F7 Z& l
FT(0) = 0: FD(0) = "Circle"& w6 Z3 b) \; r4 k9 F, l1 G/ w$ i
Set SS = ThisDrawing.SelectionSets.Add("SS")% F9 ~" F5 P% L7 b. [# [$ b! ^* j
SS.Select acSelectionSetAll, , , FT, FD% E* _6 z8 p! }8 y9 I% G! e
If SS.Count > 1 Then3 X7 W5 Z, u, F2 b% D# S
For I = SS.Count - 1 To 1 Step -1
, c# L% h8 Q& K$ e: h0 S* E, R- \. A
Set C1 = SS.Item(I)" C! h% [5 g) m5 w2 Q6 z% x
For J = I - 1 To 0 Step -1
4 K; y. s% n3 A0 M9 [7 `
Set C2 = SS.Item(J)
8 n& G' o" A) H8 ?; 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 m# v% @( t" E% G n
C1.Delete
4 I% I( h8 Q: c1 A- S
Exit For2 Z9 Z2 v& v, c6 v
End If7 L% S1 `& b7 @$ A* p
Next; w2 B) Q9 G7 Y) P1 u
Next: [6 K! ?, o7 N# o/ |! d
End If* ]6 d1 J5 z6 D, E. R

如果好了的话楼主将怎样删除线的命令一起研发下吧
