Circular component pattern in assembly

I use Solidworks 2013 SP5.

I want to pattern a part in assembly by Macro.

It doesn't work.

    Public Sub Process(ByVal swApp As SldWorks, ByVal swDoc As ModelDoc2, ByVal AssyName As String, ByVal PartName1 As String, ByVal PartName2 As String, ByVal PartName3 As String, ByVal BodyFaceName As String)

        Dim myfeature As Feature

        Dim swAssy As AssemblyDoc

        Dim filename As String = swDoc.GetTitle

        swAssy = swDoc

        swModelDocExt = swDoc.Extension

        swComp = swAssy.GetComponentByName(PartName3 & "-1")

        swPart = swComp.GetModelDoc2()

        swSelMgr = swDoc.SelectionManager

        swSelData = swSelMgr.CreateSelectData

        swFace = swPart.GetEntityByName(BodyFaceName, 2)

        swEnt = swFace

        swEnt2 = swComp.GetCorrespondingEntity(swEnt)

        swDoc.ClearSelection2(True)

        bRet = swDoc.Extension.SelectByID2(PartName1 & "-1@" & AssyName, "COMPONENT", 0, 0, 0, True, 1, Nothing, 0)

        bRet = swDoc.Extension.SelectByID2(PartName2 & "-1@" & AssyName, "COMPONENT", 0, 0, 0, True, 1, Nothing, 0)

        bRet = swEnt2.Select4(True, swSelData)  ' the selected face is reference face for circular pattern

        myfeature = swDoc.FeatureManager.FeatureCircularPattern3(8, 2 * 4 * Math.Atan(1), False, "NULL", False, True)

    End Sub

End Module
