Path MillFace

Description
The Face Mill tool creates a path to perform a facing operation on a horizontal surface.

Caveats
Using it on an inclined plane may produce unexpected results: it will still produce a path to cut a horizontal surface. The extent of the cut will be the horizontal projection of the inclined plane, performed at a height corresponding to the lowest point in that plane.

Since the path tools work on the geometry of the selected edges/faces only, and do not relate to the rest of the 3D model, the paths will not go beyond the bounds of the chosen plane, even if it is surrounded by unused stock or air. This will leave unmachined corners. These can sometimes removed with one of the dress-up tools to be found on the Path menu.
