• Define cut lines by selecting edges or datum curves, as well as by sketching the cut lines and projecting on the surfaces to be machined.

• Machine an open or closed loop of cut lines by selecting cut lines appropriately.

• Select surfaces, other than surfaces to be machined, to be used for defining the cut lines.

• Use the Auto Cutline option to create cut line tool paths automatically for machine references that include a single closed boundary edge. The boundary edge is automatically selected as the outer cut line. The inner cut line is a point that you can drag to the desired location.

• When milling multiple nonsmooth surfaces using cut lines, set the STEPOVER_TRANSITION parameter to YES to achieve a smooth tool path during spherical to conical surface transitions. The default value of this parameter is NO. You can also set the STEEP_STEP_OVER parameter to an appropriate value to create extra machining slices for a smoother tool path. You must select at least three cut lines and sequentially order the cut lines in the Cut Lines tab. See the topic Example – Cutline Milling for details.
