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 LT 2008 (and later releases)
in AutoCAD LT 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 1518 objects maintain visual fidelity
when they are viewed in AutoCAD LT 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 1537. When
visual fidelity is on, annotative objects are decomposed and scale
representations are saved (in an anonymous block on page 1518) to separate
layers. These layers are named based on their original layer and appended
with a number. If you explode the block in AutoCAD LT 2007 (or earlier
releases), and then open the drawing in AutoCAD LT 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 LT 2008 (and
later releases) in AutoCAD LT 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
