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 displays whatever is directly behind it. You can move the viewpoint
of a lens to make any location appear in the lens, which 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 do not display objects on other pages, sheets, slides, or
frames.
You can set a viewpoint visually by clicking in the document, or precisely, by entering values for the
Absolute or Relative position.
To set a viewpoint visually:
1. Select the lens object.
2. In the Properties bar or SpriteEffects palette, select Relative or Absolute.
3. Click Choose.
4. Move the pointer in the document and click to set the viewpoint.
The area you click appears centered in the lens.
To set a viewpoint precisely:
1. Select the lens object.
2. In the Properties bar or SpriteEffects palette, select one of the following:
Absolute: Select Absolute and enter horizontal (X) and vertical (Y) distances from the
rulers’ zero point to the viewpoint; e.g., enter 0 in the X and Y boxes to set the viewpoint
at the zero point. If you move the lens object, the viewpoint does not change.
Relative: Select Relative and enter horizontal (X) and vertical (Y) distances from the
center of the lens to the viewpoint. Positive values move the viewpoint down and right of
the lens center. Negative values move the viewpoint up and left of the lens center; e.g., to
set the viewpoint 1 ruler unit left of the lens center, enter -1 (X) and 0 (Y). If you move
the lens, the viewpoint changes.
