An improvement on the straight lines would be to use arcs at the ends for smoother movement.
If one wants to surface off for example an 8x12 area:
then the easiest way to do this is to increase the Stock Width by 2 inches and the Height by 1 inch:
Center the rectangle showing the area one wishes to cut as a reference:
Align Vectors
and then draw in the ends:
(and increase the Grid size to match the desired stepover)
Then go into Node Edit mode:
and Cut each circle:
then delete:
Done
Draw in geometry to connect things:
Select the geometry and use Join Vectors to connect it:
Yes
Then use Linear Array:
To replicate as needed:
Draw in the final bits of geometry if need be:
and join as well:
Then adjust as desired for Stock size, origin, toolpath, &c.
