Selecting and saving a contour
 Select the mode for choosing a contour. The TNC
hides the layers shown in the left window, and the
right window becomes active for contour selection.
 To select a contour element, click the desired contour
element with the left mouse button. The selected
contour element turns blue. At the same time, the
TNC marks the selected element with a symbol
(circle or line) in the left window.
 To select the next contour element, click the desired
contour element with the left mouse button. The
selected contour element turns blue. If further
contour elements in the selected machining
sequence are clearly selectable, these elements turn
green. Click on the last green element to assume all
elements into the contour program. The TNC shows
all selected contour elements in the left window. The
TNC displays elements that are still green in the NC
column without a check mark. This elements are not
output to the contour program when it is saved.
 If necessary you can also deselect elements that you
already selected, by clicking the element in the right
window again, but this time while pressing the CTRL
key.
 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.
 Confirm the entry: The TNC saves the contour
program in the directory in which the DXF file is also
saved.
 If you want to select more contours, press the
CANCEL SELECTED ELEMENTS soft key and select
the next contour as described above.
You must use the touchpad on the TNC keyboard or a
mouse attached via the USB port in order to select a
contour.
If you are not using the contour program in the smarT.NC
operating mode, you must specify the machining
sequence when selecting the contour so that it matches
the desired machining direction.
Select the first contour element such that approach
without collision is possible.
If the contour elements are very close to one another, use
the zoom function.
