The "Pole Input" input window opens.
4. Enter all the data available from the workpiece drawing in the input
screen (e.g. length of straight line, target position, transition to next
element, angle of lead, etc.).
5. Press the "Accept" softkey.
The contour element is added to the contour.
6. When entering data for a contour element, you can program the transi-
tion to the preceding element as a tangent.
Press the "Tangent to prec. elem." softkey. The angle to the preceding
element α2 is set to 0°. The "tangential" selection appears in the pa-
rameter input field.
7. Repeat the procedure until the contour is complete.
8. Press the "Accept" softkey.
The programmed contour is transferred to the machining plan (program
view).
9. If you want to display further parameters for certain contour elements,
e.g. to enter additional commands, press the "All parameters" softkey.
