Auxiliary points
You can enter the coordinates of auxiliary points that are located on
the contour or in its proximity for both free-programmed straight
lines and free-programmed circular arcs. The soft keys are available
as soon as you initiate the FK dialog with the FL, FLT, FC or FCT soft
key.
Auxiliary points for a straight line
If the auxiliary points are located on a straight line or on the
extension of a straight line, use the soft keys listed in the table at
upper right.
If the auxiliary points are located at a distance D from a straight line,
use the soft keys listed in the second table at right.
Auxiliary points for a circular arc
For circular arcs, you can enter 1 auxiliary point on the contour. The
available soft keys are listed in the table at lower right.
