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. The TNC does not save

these elements to the contour program. You can also

include the marked elements in the contour program

by clicking in the left window



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

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 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.

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.
