HEIDENHAIN ITNC 530 - PILOT SMART NC Manual page 194

If you have selected polylines, the TNC shows a two-level
ID number in the left window. The first number is the
serial contour element number, the second element is the
element number of the respective polyline from the DXF
file.
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
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.
If you call the DXF converter from a form, smarT.NC
automatically closes the DXF converter after you have
completed the SAVE SELECTED ELEMENTS function.
Then smarT.NC writes the defined contour name to the
input field from which you have started the DXF
converter.
