Use Perspective view to see the model as as it would appear to the human eye when manufactured.
Displays the model in perspective view unless you orbit the view to an orthogonal position where it changes to an orthogonal view. The view mode is a blend of orthographic and perspective views.
In Perspective Camera mode, use the Zoom, and Pan commands with key combinations.
Set the model view to Perspective Camera mode:
On the ribbon View tab, Appearance panel, select the Perspective Camera.
Position the model so that you can sight down the axis of your intended initial motion.
Do one of the following:
PressSHIFT + CTRL+F3.
Adjust camera position and lens focal length simultaneously. For instance, for a given view or view path, use a wider angle lens, if necessary.
