Setting a lens viewpoint The viewpoint of a lens is a point in the document that appears in the lens. The default viewpoint is at the center of the lens, so the lens dis- plays whatever is directly behind it. You can move the viewpoint of a lens to make any location appear in the lens. This is useful for displaying close-ups of illustrations. The center of a lens is focused on the lens viewpoint. If you move the viewpoint, the new location appears centered in the lens object. The viewpoint of a lens can be set anywhere on the same page, slide, sheet, or frame as the lens object. Lenses can display objects on all visible layers on the same page, sheet, slide, or frame. Lenses will not display objects on other pages, sheets, slides, or frames. Setting a viewpoint visually Use this procedure when you want to click in the document to set the viewpoint for a lens. 1 Select the lens object. 2 In the SpriteEffects palette, select Relative or Absolute; these options are described next. 3 Click Choose. 4 Move the pointer in the document and click to set the view- point. The point you click appears centered in the lens. Absolute and relative viewpoints To set the relationship of the viewpoint to a lens object, select Abso- lute or Relative in the SpriteEffects palette.
