Quick selection of hole positions by entering a diameter
U 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.
U Select the last soft-key row
U Open the dialog for diameter input: enter any diameter in the
pop-up window displayed by the TNC
U 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.
U If required, configure the filter settings (see "Filter settings"
on page 203) and click the Use button to confirm: The TNC
loads the selected positions into the left window (displays a
point symbol)
U 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.
