This switch can be set to find small radius areas and inner sharp edges in surface model. Such areas will be left out from toolpath generation. Inside corners cause in tool paths so called "fish tails". Such fish tails are removed by turning on this switch. This flag can also be considered as a fillet generator. The surface model is rounded (filleted) in the direction of toolpath slices with a radius to avoid small radii and inner sharp corners. The applied radius is the main tool radius plus the current stock to leave value. The fillet generation is independent of tool type and shape. In most cases, this switch is used in presence of a ball cutter, lollipop cutter or a conical cutter with ball tip. If swarf machining is applied (side cutting), then also cylinder or torus cutters are used together with this switch.

To increase the round radius, press the Round corners button (available when the check box is checked).
The Round corners dialog is displayed. Enter the required radius in the Additional radius field.
