Sketches not exported when using CreateFlatPatternViewFromModelView API

I dont want to export hidden sketches(want to export only shown sketches) while exporting to dxf/dwg so i'm using drwing file (NewDocument) and CreateFlatPatternViewFromModelView API. But the shown sketches too are not exported.

When i manually do(please watch the attached video) sketches are exported, but not through API. Please provide me a solution.

The following is the macro i created, but not exporting the sketched as expected.

Sub main()

  Set swApp = _

Application.SldWorks

Set Part = swApp.ActiveDoc

Set Part = swApp.NewDocument("C:\ProgramData\SolidWorks\SolidWorks 2013\templates\Drawing.drwdot", 2, 0.2794, 0.4318)

swApp.ActivateDoc2 "Draw14 - Sheet1", False, longstatus

Set Part = swApp.ActiveDoc

boolstatus = Part.CreateFlatPatternViewFromModelView("C:\Users\MERCURY\Desktop\prob 1\Part14.SLDPRT", "Default", 0.549162197986577, 0.498221946308725, 0)

boolstatus = Part.ActivateView("Drawing View1")

Part.ClearSelection2 True

boolstatus = Part.ActivateSheet("Sheet1")

Part.ViewZoomtofit2

longstatus = Part.SaveAs3("C:\Users\balajik\Desktop\SW sketches\Part14.SLDDRW", 0, 2)

Set Part = Nothing

swApp.CloseDoc "Part14 - Sheet1"

Set Part = swApp.ActiveDoc

Dim myModelView As Object

Set myModelView = Part.ActiveView

myModelView.FrameLeft = 0

Set myModelView = Part.ActiveView

myModelView.FrameState = swWindowState_e.swWindowMaximized

swApp.ActivateDoc2 "Part14.SLDPRT", False, longstatus

Set Part = swApp.ActiveDoc

Set myModelView = Part.ActiveView

myModelView.FrameState = swWindowState_e.swWindowMaximized

End Sub
