Commands associated with definitions are shown in parentheses at the end
of the definition.
absolute coordinates Coordinate values measured from a coordinate system's
origin point. See also origin, relative coordinates, user coordinate system (UCS),
world coordinates, and world coordinate system (WCS).
acquired point In the tracking or object snap tracking methods of locating
a point, an intermediate location used as a reference.
acquisition marker During tracking or object snap tracking, the temporary
plus sign displayed at the location of an acquired point.

run a product in compliance with the product's end-user license agreement.
adjacent cell selection A selection of table cells that share at least one
boundary with another cell in the same selection.
affine calibration A tablet calibration method that provides an arbitrary linear
transformation in two-dimensional space. Affine calibration requires three
calibration points to allow a tablet transformation that combines translation,
independent X and Y scaling, rotation, and some skewing. Use affine calibration
if a drawing has been stretched differently in the horizontal or vertical
direction. (TABLET)
alias A shortcut for a command. For example, CP is an alias for COPY, and Z
is an alias for ZOOM. You define aliases in the acadlt.pgp file.
aligned dimension A dimension that measures the distance between two
points at any angle. The dimension line is parallel to the line connecting the
dimension's definition points. (DIMALIGNED)
angular dimension A dimension that measures angles or arc segments and
consists of text, extension lines, and leaders. (DIMANGULAR)
