The TNC automatically generates the first and last blocks of the
program.
If you do not wish to define a blank form, cancel the dialog
at Working spindle axis X/Y/Z by pressing the DEL key!
The TNC can display the graphics only if the shortest side
is at least 50 µm long and the longest side is no longer
than 99 999.999 mm.
