Draw some Lines

Instead of LINE, you can also
type: L this is an "alias" - which is
a short-cut.
The exact positions of these lines
is not important.
We will now draw some more
graphics and then save and exit
AutoCAD.
Type LINE
Move the crosshair to near the
bottom-left of the rectangle and
click the left mouse button, then
move the crosshair to the top-
right of the rectangle and again
click the left mouse button.
Remember this! If you press after
you finish a command, the
command is re-issued.
Press to terminate the command,
and then press again to re-start
the command!
Draw a line from the top-left to
the bottom-right of the rectangle,
and then press to end the
command.
This will save the drawing and
exit AutoCAD - don't PANIC!
Now type:
QUIT
You will be prompted to save the
changes you've made - click OK.
