例

VBA:

Sub Example_MajorRadius()
    ' This example creates an Ellipse in model space and displays
    ' both the Major radius and the Minor radius of the new Ellipse
  
    Dim ellObj As AcadEllipse
    Dim majAxis(0 To 2) As Double, center(0 To 2) As Double
    Dim radRatio As Double
    
    ' Create an ellipse in model space
    center(0) = 5: center(1) = 5: center(2) = 0
    majAxis(0) = 10: majAxis(1) = 20: majAxis(2) = 0
    radRatio = 0.3
    Set ellObj = ThisDrawing.ModelSpace.AddEllipse(center, majAxis, radRatio)

    ThisDrawing.Application.ZoomAll
    
    ' Display radius information
    MsgBox "The major radius of the new Ellipse is: " & ellObj.majorRadius & vbCrLf & _
           "The minor radius of the new Ellipse is: " & ellObj.minorRadius
End Sub
