Are you trying to inlay a pool cue?
As far as drawing the vectors, you can draw them individually then use the join vector tool to make a single closed vector.
If you are inlaying the pool cues, I wouldn't do it as a rotary job (though I would do it on your rotary axis). I would rotate the axis to where you want, then cut your inlay pocket, rotate and repeat to get all the pockets cut. If you pocket with a rotary toolpath, you will have a hard time making the male inlay to fit the curved pocket.
