VB6使用GetLoopAt时报错 “缺少函数或变量”

ChiN丶

完整代码：
Option Explicit
Private Sub Command1_Click()
    Dim acadApp As AcadApplication
    Set acadApp = GetObject(, "AutoCAD.Application")
    Dim hatchObj As AcadHatch
    Dim patternName As String
    Dim PatternType As Long
    Dim bAssociativity As Boolean
    '定义填充
    PatternType = 0
    patternName = "SOLID"
    bAssociativity = True '填充图案与边界相关联
    '创建填充对象
    Set hatchObj = acadApp.ActiveDocument.ModelSpace.AddHatch(PatternType, patternName, bAssociativity)
    '创建两个同心圆作为填充边界
    Dim OuterLoop(0 To 0) As AcadEntity
    Dim InnerLoop(0 To 0) As AcadEntity
    Dim center(0 To 2) As Double
    Dim radius As Double
    center(0) = 1: center(1) = 2: center(2) = 0
    radius = 20
    Set OuterLoop(0) = acadApp.ActiveDocument.ModelSpace.AddCircle(center, radius)
    Set InnerLoop(0) = acadApp.ActiveDocument.ModelSpace.AddCircle(center, radius / 2)
    '向填充对象添加填充边界
    hatchObj.AppendOuterLoop (OuterLoop)
    hatchObj.AppendInnerLoop (InnerLoop)
    '用Evaluate方法进行求值并显示填充
    hatchObj.Evaluate
    acadApp.ActiveDocument.Regen True
    '输出填充的边界数
    Print (hatchObj.NumberOfLoops)
    '判断边界的类型
    Dim loopNum As Integer
    loopNum = hatchObj.NumberOfLoops
    Print (loopNum)

    Dim num As Integer
    num = 0
    Dim loopObjs As Variant
    Dim hatLoop As Object
   'hatLoop = Nothing
    Do While num < loopNum
        Set hatLoop = hatchObj.GetLoopAt(num, loopObjs)
        num = num + 1
        If hatLoop.IsPolyline Then
           Print (111)
        Else
           Print (222)
        End If
    Loop
    ZoomExtents

End Sub
其中Set hatLoop = hatchObj.GetLoopAt(num, loopObjs)这句一直报缺少函数或变量的错  不知道为什么

GetLoopAt 没有返回值，你怎么让他返回呀
call hatchObj.GetLoopAt(num, loopObjs)
