Fifth example - Line tool ( Fig. 2.10 )

Another method of constructing accurate drawings is by using a method
known as tracking . When Line is in use, as each Specify next point:
appears at the command line, a rubber-banded line appears from the last
point entered. Drag the rubber-band line in any direction and enter a
number at the keyboard, followed by a right-click. The line is drawn in the
dragged direction of a length in units equal to the entered number.

In this example because all lines are drawn in vertical or horizontal
directions, either press the F8 key or click the ORTHO button in the status
bar which will only allow drawing horizontally or vertically.
1. Close the drawing and open a new acadiso.dwt window.
2. Left-click on the Line tool icon and enter fi gures as follows at each
prompt of the command line sequence:
Command:_line Specify fi rst point: enter 65,220
right-click
Specify next point: drag to right enter 240
right-click
Specify 145 right-click

Specify next point or [Undo]: drag left enter 65
right-click
Specify

next point: drag down enter

next point or [Undo]: drag upwards enter 25

right-click
Specify next point or [Close/Undo]: drag left
enter 120 right-click
Specify next point or [Close/Undo]: drag upwards
enter 25 right-click
