While you are writing the part program, you can have the TNC
generate a graphic illustration of the programmed contour.
To generate/not generate graphics during programming:
ú To switch the screen layout to displaying program blocks to the
left and graphics to the right, press the SPLIT SCREEN key and
PGM + GRAPHICS soft key.
ú Set the AUTO DRAW soft key to ON. While you are
entering the program lines, the TNC generates each
path contour you program in the graphics window in
the right screen half.
If you do not wish to have graphics generated during programming,
set the AUTO DRAW soft key to OFF.
Even when AUTO DRAW is switched ON, graphics are not
generated for program section repeats.

ú Use the arrow keys to select the block up to which you want the
graphic to be generated, or press GOTO and enter the desired
block number.
ú To generate graphics, press the RESET + START soft
key.
Additional functions are listed in the table at right.
