Icon Setting
Undoes the most recent step.
Contour transfer mode:
The tolerance specifies how far apart neighboring
contour elements may be from each other. You
can use the tolerance to compensate for inaccu-
racies that occurred when the drawing was made.
The default setting is 0.001 mm
Arc mode:
Arc mode defines whether circular arcs are output
in C format or CR format (e.g., for cylinder surface
interpolation) in the NC program.
Point transfer mode:
Specifies whether the control should display the
tool path as a dashed line during the selection of
machining positions
Path optimization mode:
The control optimizes the tool traverse movement
so that there are shorter traverse movements
between the machining positions. When the icon
is pressed again, the optimization is reset
Hole position mode:
The control opens a pop-up window in which you
can filter holes (full circles) based on their size
