VBA中如何获得CAD modelspace中坐标

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
