Perspective Property

       

Determines whether the extrusion appears in perspective. Read/write MsoTriState.

MsoTriState can be one of these MsoTriState constants.
msoCTrue
msoFalse The extrusion is a parallel, or orthographic, projection—that is, if the walls don't narrow toward a vanishing point. 
msoTriStateMixed
msoTriStateToggle
msoTrue The extrusion appears in perspective—that is, if the walls of the extrusion narrow toward a vanishing point. 

Example

This example sets the extrusion depth for shape one on myDocument to 100 points and specifies that the extrusion be parallel, or orthographic.

Set myDocument = ActivePresentation.Slides(1)
With myDocument.Shapes(1).ThreeD
    .Visible = True
    .Depth = 100
    .Perspective = msoFalse
End With
