clipped external reference to invert the
clipping boundary.
Edit In-Place
In-Place Reference Editing, or REFEDIT,
is now included in AutoCAD LT 2010.
This feature enables you to edit an
externally referenced drawing directly,
without opening it in its own window.
Open
Open Reference is another AutoCAD
LT 2010 command that was previously
available only in AutoCAD. This tool
enables you to select a referenced file
and instantly open it in the appropriate
program for that reference type. Now
you can quickly open a referenced file
without having to list it, remember its
name, and browse your computer or
server to find it.
