Limitations of Saving to Earlier Versions
Saving a drawing in Release 2000/LT 2000 format is subject to the following
limitations:
File size can increase.
Saving a drawing in Release 12/LT 2 DXF format is subject to the following
limitations:
Lightweight polylines and hatch patterns are converted to Release 12
polylines and hatch patterns.
All solids, bodies, regions, ellipses, leaders, multilines, rays, tolerances, and
xlines are converted to lines, arcs, and circles as appropriate.
Groups, complex linetypes, and preview images are not displayed.
Many objects are lost if you save a drawing as Release 12 and open it in
Release 2000/LT 2000 or later.
Multiple layouts and layout names are lost. Only the Model layout and
the current named layout are saved.
Spaces in the names of layers and other objects are converted to
underscores, and their maximum length is 32 characters.
The status of external references as unloaded is lost.
Work with AutoCAD Drawings in AutoCAD LT
AutoCAD LT offers full compatibility when working with AutoCAD drawings.
However, you should understand how AutoCAD LT handles AutoCAD-only
features.
Work with Fields
In AutoCAD, you can insert LispVariables fields, which are not available in
AutoCAD LT. However, the drawings created in AutoCAD that contain
LispVariables can be opened without errors in AutoCAD LT, and the cached
value is displayed.
Work with Multiple User Coordinate Systems
In AutoCAD, you can choose to use a different user coordinate system (UCS)
in each viewport in a single drawing file. In AutoCAD LT, you can use only
