It's even easier in Dolphin.
You don't even have to darw your toolpath, just the outer shape.
Then if you select area clear you get many, many ways to machine this
just by editing the Area clear box. You can select contour machining,
uni-directional machining, bi- directional machining and by altering
tool overlap and machining angle you have access to literally
hundreds of ways without ever having to draw one toolpath.

Again this just goes to show how simple and advanced Dolphin really
is.

the rule is to never grind/polish the same path twice or
