Adjusts the smoothness of shaded and rendered objects and objects with

Use Drawings from Different Versions and Applications
You can share drawing files from AutoCAD and AutoCAD LT, drawing files
from previous versions, and drawing files that contain custom objects. In some
cases there are limitations.
Work with Drawings in Earlier Releases
When you work with drawings created in AutoCAD 2008 (and later releases)
in AutoCAD 2007 (and earlier releases), you should be aware of the following
visual fidelity issues.
Visual Fidelity for Annotative Objects in Previous Releases
You can specify that
annotative on page 2151 objects maintain visual fidelity
when they are viewed in AutoCAD 2007 (and earlier releases) with the
SAVEFIDELITY system variable.
If you work primarily in model space, it is recommended that you turn off
visual fidelity (set SAVEFIDELITY to 0). However, if you need to exchange
drawings with other users, and layout fidelity is most important, then visual
fidelity should be turned on (SAVEFIDELITY set to 1).
Annotative objects may have multiple
scale representations on page 2180. When
visual fidelity is on, annotative objects are decomposed and scale
representations are saved (in an anonymous block on page 2151) to separate
layers. These layers are named based on their original layer and appended
with a number. If you explode the block in AutoCAD 2007 (or earlier releases),
and then open the drawing in AutoCAD 2008 (or later releases), each scale
representation becomes a separate annotative object, each with one annotation
scale. It is recommended that you do not edit or create objects on these layers
when working with a drawing created in AutoCAD 2008 (and later releases)
in AutoCAD 2007 (and earlier releases).
When visual fidelity for annotative objects is not selected, a single model
space representation is displayed on the Model tab. Depending on the setting
of the ANNOALLVISIBLE system variable, more annotation objects may be
