maybe use fixed contour, curve/point method, make multiple sets of curves, and offset tool left on curves in method
Thanks Juraj to your reply, I have tried your suggestion but the result is different from what I am expecting.
I want the result as the same as 3D profile operation where you can control the depth of the created tool path on the part and considered that all non-connected lines are individual lines.
Thank you very much to your reply.
Thanks Juraj for your input to use the fixed contour line/points operation, it did solve the problem. What I did first is I used the command extract geometry and then allow the self-intersection option to create the tool path separate on each lines.
