    Dim pviewportObj As AcadPViewport
    Dim center(0 To 2) As Double
    Dim width As Double
    Dim height As Double
    
    ' Define the paper space viewport
    center(0) = 3: center(1) = 3: center(2) = 0
    width = 40
    height = 40
    
    ' Change from model space to paper space
    ThisDrawing.ActiveSpace = acPaperSpace

    ' Create the paper space viewport
    Set pviewportObj = ThisDrawing.PaperSpace.AddPViewport(center, width, height)
    pviewportObj.DISPLAY True
    ThisDrawing.mspace = True
    ThisDrawing.ActivePViewport = pviewportObj
    ThisDrawing.Regen acAllViewports
    
    ' Find the value for RemoveHiddenLines for the viewport
    Dim removeHidden As Boolean
    removeHidden = pviewportObj.RemoveHiddenLines
    MsgBox "The value of the RemoveHiddenLines property for the paperspace viewport is " & pviewportObj.RemoveHiddenLines, , "RemoveHiddenLines Example"
