U
To save the selected contour elements in a plain-
language program, enter any file name in the pop-up
window displayed by the TNC. Default setting: Name
of the DXF file. If the name of the DXF file contains
special characters or spaces, the TNC replaces the
characters with underscores
U Confirm the entry: The TNC saves the contour
program in the directory in which the DXF file is also
saved
U If you want to select more contours: Press the
CANCEL SELECTED ELEMENTS soft key and select
the next contour as described above
The TNC also transfers two workpiece-blank definitions
(BLK FORM) to the contour program. The first definition
contains the dimensions of the entire DFX file. The
second one, which is the active one, contains only the
selected contour elements, so that an optimized size of
the workpiece blank results.
The TNC only saves elements that have actually been
selected (blue elements), which means that they have
been given a check mark in the left window.
