Export .PNG in perspective view

Hello fellow solidworkers,

I want to export a .PNG file in persepective view when i have checked a checkbox (SetPerspective) I have found the following API command Perspective (IView). When i try to use it, it does not work.

I hope somebody can help.

Code:

Option Explicit

Option Compare Text

Dim swApp As SldWorks.SldWorks

Dim Part As ModelDoc2

Dim lErrors As Long

Dim lWarnings As Long

Dim swModel As ModelDoc2

Sub CreatePNG()

Dim sFilename       As String

Dim docType As swDocumentTypes_e

Set swApp = Application.SldWorks

Set Part = swApp.ActiveDoc

'If CheckBox1() = False Then 'add command here = False

sFilename = Part.GetPathName

sFilename = Left(sFilename, Len(sFilename) - 7)

sFilename = sFilename & ".png"

Part.SaveAs2 sFilename, 0, True, False

End Sub

Private Sub ButCreatePNG_Click()

CreatePNG

EDIT:  simplified the code, added marco
