aclt.dwt
and
acltiso.dwt;
however, any drawing can be used as a
template.
text style
A named, saved collection of settings that determines the
appearance of text characters—for example, stretched, compressed,
oblique, mirrored, or set in a vertical column.
thaw
A setting that displays previously frozen layers.

tool palette
tabbed areas within the Tool Palettes window that provide an
efficient method for organizing, sharing, and placing blocks and
hatches.
tree view
A hierarchical list that can be expanded or collapsed to control the
amount of information displayed. Tree views are available in
DesignCenter, the Purge dialog box, and the Help system.
UCS

UCS icon
An icon that indicates the orientation of the UCS axes. (UCSICON)
user coordinate system
(UCS)
A user-defined coordinate system that defines the orientation of the
X
,
Y
, and
Z
axes in 3D space. The UCS determines the default
placement of geometry in a drawing.
