Top Facing, 2½ Axis
Top Facing is a method of generating planar toolpaths using the part and the stock as geometry limits. This method automatically calculates a toolpath that covers the XY extents of the stock model. The Z Containment controls in the Cut Levels tab allows you to reference either the Part Top or the Stock Top in addition to the standard Step down controls.
