Cutting Lines (one direction only) after flattening

A Facing toolpath should work for this — it’s an option in Pro.

The only toolpath which is guaranteed to afford control over this is a Keyhole toolpath:

but it is quite limited in terms of the length which it is allowed to cut.

If you have a region where you don’t mind the spinning tool moving, then it should work to draw a continuous path where one line crosses the material cutting, then it moves laterally off the stock, traverses back to the original side, then laterally to the next line position, then repeats.

At that point, it’s easier to just use a special purpose tool or hand-code G-code.
