Are the Advanced 3D Machining processes a sort of "upgrade" of the Surfacing processes? Do they deprecate, render obsolete, etc., the Surfacing processes? Whats the relationship? I see, for example, that some of the Surfacing processes, like Lace Cut, Intersection, have Advanced 3D Machining counter parts.
I'm just wondering where to focus my attention. Should I simply concentrate on Advanced 3D Machining at this point, and avoid Surfacing processes altogether? Or do I need to know both?
