Save Active View stores the active view to an internal buffer. If you have framed a shot in any view other than a camera, use Save Active View to preserve the viewport’s appearance. The saved active view is saved with the scene file. Once saved, you can retrieve it using Restore Active View.
The viewport that will be restored is displayed in the menu item (for example, "Save Active Perspective View"). You can save and restore up to eight different views (Top, Bottom, Left, Right, Front, Back, Orthographic, Perspective).
Viewport changes that are saved include viewport shading type and point of view (POV): perspective or orthographic, zoom and rotations, and field-of-view (FOV).
Show Safe Frames and Viewport Clipping settings are not saved. If these settings are important to the view, make a note of what they are so you can reset them after restoring the view.
