Quick selection of hole positions in an area defined by the mouse
 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
 Press the shift key on the keyboard and drag the left
mouse button to define an area in which the TNC is to
adopt all included circle centers as hole positions: the
TNC opens a window in which you can filter the holes
by size
 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
