摘要: 将给定对象复制到同一位置。

将给定对象复制到同一位置。

支持的平台：仅窗口

工务局：

RetVal = object.Copy

对象

类型：所有图形对象，属性引用，尺寸

此方法适用的对象。

返回值（RetVal）

类型：所有图形对象，属性引用，尺寸

新创建的重复对象。

言论

属性引用：不应尝试对对象使用此方法。objects 继承此方法，因为它们是图形对象之一，但是，对属性参照执行此操作是不可行的。AttributeReferenceAttributeReference

注意：不能在循环访问集合的同时执行此方法。迭代将为只读操作打开工作空间，而此方法将尝试执行读写操作。在调用此方法之前完成任何迭代。

例子

工务局：

Sub Example_Copy()
    ' This example creates a circle and then copies
    ' that circle. The new circle is then moved.
    
    ' Create the circle
    Dim circleObj As AcadCircle
    Dim center(0 To 2) As Double
    Dim radius As Double
    center(0) = 2#: center(1) = 2#: center(2) = 0#
    radius = 0.5
    Set circleObj = ThisDrawing.ModelSpace.AddCircle(center, radius)
    ZoomAll
    MsgBox "Copy the circle.", , "Copy Example"
    
    ' Copy the circle
    Dim copyCircleObj As AcadCircle
    Set copyCircleObj = circleObj.Copy()
    
    ' Define the points that make up the move vector
    Dim point1(0 To 2) As Double
    Dim point2(0 To 2) As Double
    point1(0) = 0: point1(1) = 0: point1(2) = 0
    point2(0) = 2: point2(1) = 0: point2(2) = 0
        
    MsgBox "Move the copied circle 2 units in the X direction.", , "Copy Example"
    
    ' Move the circle and color it
    copyCircleObj.Move point1, point2
    
    ZoomAll
    MsgBox "Move completed.", , "Copy Example"
    
End Sub
