On the view menu is a command called Set 3D View… This command can be used to set up a perspective view, but it does not save the view. In order to save the view you have to create a saved view after setting perspective. While you can use this command to set the view, a more efficient way to set your view is to use the Renderworks Camera. Not only does the Renderworks Camera remember the view, you can use the Visualization Palette to restore the view (much like a saved view) and you can also use the Renderworks Camera to create a viewport. My recommendation is to use the Renderworks Camera to setup your views.
