Generating / Not generating graphics during
programming
While you are writing the part program, you can have the TNC
generate a 2-D pencil-trace graphic of the programmed contour.
 To switch the screen layout to displaying program blocks to the left
and graphics to the right, press the SPLIT SCREEN key and
PROGRAM + GRAPHICS soft key.
 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.

programming, set the AUTO DRAW soft key to OFF.
Even when AUTO DRAW ON is active, graphics are not generated for
program section repeats.
