To use tracking to specify a point
1 Start a command, such as the LINE command.
2 Hold down Shift and right-click in the drawing area. Click Tracking.
3 Specify a point.
4 Move the cursor directly up, down, left, or right until you see the
rubber-band line.
The direction of movement affects the tracking direction. Notice that if
you move the cursor from left to right, you must then move it directly
over the last point specified in order to move it up or down.
5 Specify a second point.
6 Press Enter to end tracking.
The start point of the line snaps to the imaginary intersection of the
vertical and horizontal paths extending from the points you specified.
The position is determined by the direction in which you moved the
cursor after specifying the first point.

TRACKING (Command Modifier)
Locates a point from a series of temporary points.
Specify Distances
When specifying a point, you can enter distances, offsets, and measured
intervals.
Enter Direct Distances
You can specify a point by moving the cursor to indicate a direction and then
entering the distance.
To specify a line length quickly, without entering coordinate values, you can
specify a point by moving the cursor to indicate a direction and then entering
the distance from the first point. You can enter calculated distances and points
using the AutoCAD calculator (CAL).
