创建类似pline命令的acadlwpolyline

Public Sub Main()
    Dim startPnt As Variant
    Dim returnPnt As Variant
    Dim returnPntList(0 To 5) As Double
    Dim plineObj As AcadPolyline

    On Error Resume Next

    If Err Then GoTo SubEnd
    
    returnPntList(0) = startPnt(0)

    returnPntList(3) = returnPnt(0)
    returnPntList(4) = returnPnt(1)

        If Err Then GoTo SubEnd
    
        plineObj.AppendVertex returnPnt
        ThisDrawing.Regen (acActiveViewport)
    Wend
    
SubEnd:
