External References
AutoCAD LT  provides a consolidat-
ed interface and increased flexibility for
working with externally referenced files
in a variety of formats, including DWG,
DWF, DGN, PDF, and image files.
The Reference Panel
The Reference panel on the Insert tab
of the ribbon provides tools for you to
attach and modify externally referenced
files. You can control the display and
plotting of reference frames and turn
on or o the ability to snap to the refer-
enced geometry.
PDF Underlays
AutoCAD LT  addresses one of the
top Autodesk User Group International
(AUGI
®
) wish list requests by enabling
you to attach a PDF file to an AutoCAD
LT drawing as an underlay. You can work
with PDF underlays in the same way
you work with other external references
including DWG, DWF, DGN, and Image
files. You can even snap to key points
on PDF geometry using familiar object
snaps.
Clip
The ability to clip an external reference is
now fully functional in AutoCAD LT. Use
this tool to show only the portion of the
file that you need.
