Quick selection of hole positions by entering a diameter
 Select the mode for choosing a machining position.
The TNC hides the layers shown in the left window,
and the right window becomes active for position
selection
 Open the dialog for diameter input: enter any diameter
in the pop-up window displayed by the TNC
 Enter the desired diameter and confirm it with the
ENT key: the TNC searches the DXF file for the
entered diameter and then shows a pop-up window
with the diameter selected that is closest to the
diameter you entered. Also, you can retroactively
filter the holes according to size
 If required, configure the filter settings (see "Filter
settings" on page 254) and click the Use button to
confirm: The TNC loads the selected positions into
the left window (displays a point symbol)
 If necessary you can also deselect elements that you
already selected, by dragging an area open again, but
this time while pressing the CTRL key
 Save the selected machining positions to the
clipboard of the TNC so that you can then insert them
as a positioning block with cycle call in a plain-
language program, or
 To save the selected machining positions to a point
file, enter the target directory and 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. As an
alternative, you can also select the file type: Point
table (.PNT), pattern generator table (.HP) or plain-
language program (.H). If you save the machining
positions to a plain-language program, the TNC
creates a separate linear block with cycle call for
every machining positon (L X... Y... M99). You can
also transfer this program to old TNC controls and run
it there.
 Confirm the entry: The TNC saves the contour
program to the directory in which the DXF file is also
saved
 If you want to select more machining positions in
order to save them to a different file, press the Cancel
selected elements icon and select as described
above
