Contour toolpaths remove material along a path defined by a chain of curves. Contour toolpaths only follow a chain; they do not clean out an enclosed area. 2D contour toolpaths cut geometry in a single plane (typically XY) at a constant depth (Z = absolute depth). 3D contour toolpaths cut geometry in XY and Z, where the Z depth can vary over the toolpath. 3D is used where the geometry for each cutting pass is not contained within a single plane (Z = incremental depth). Only available if you chain 3D geometry as part of the contour toolpath.
— Contour the Outside Profile:
Select Toolpath Group-1 » right mouse click » Mill toolpaths » Contour
» select Chain (chain the contour in a CW direction) » select the outside profile edge » select OK to exit.
