Starting in NX 3, any non-orthogonal view on a drawing can be set to be in Perspective. Just select the boundary of the view, press MB3 and select Style and go to the tab labeled "Perspective" and toggle on the "Perspective" option. You can also set the distance factor to control the extent of the "vanishing point" effect.
