About the Perspective View
The perspective view renders a realistic view of models, images, or graphics. Distant Objects appear smaller than objects in the foreground. Perspective is the way in which models appear to the eye depending on their spatial attributes or their dimensions, and the position of the eye relative to the models.
You can design the model in Perspective mode without switching to the Orthographic mode.
Perspective view types such as Walk Through, Fly Through, From To, and Follow Path allow you to manipulate the view of the model in perspective. You can also manipulate the eye distance, focal length, and depth of field to adjust the amount of perspective and the viewing angle for the model.
