Next. click Compile at the bottom of the G-code editor window, and
your plot should look like Figu re 10.21 , wh ich reflects how a 1/ 4-

If you lea ve the first tool set to 0.0 and edit too ls from 2 up , you
will see thin lines plotted when you first import your graphic, but
you can preview a new tool diameter by addi ng T002 or T003 etc,
as a new line in the G-code editor. If you use this command at the
beginning of the program (after the G90 command) the entire plot
will reflect the tool. If you add it halfway through. then onl y the
lines after the co mma nd will reflect the cha nge (see Figu re 1O.22l.
Cha nging bit size in the plot window is a great way to see what a
bit or pen will make if it follows the tool path. It is esse ntial to con -
sider the type and size of too l when generating the a rtwork for a
project. You probably have plenty of fonts on you r computer with
which to experiment and if you don 't like the way a font works as
a plotter file, then import the plotter file back into CorelDraw and
pro ceed to edit it. Any graphic you create with Corel Draw can also
be exported as a DXF file, but befo re you can export as a DXF you
need to convert all the text to curves. Select all the text an d open
