Are you V-Carve machining? If so CamBam might be what you need, along with the V-Engrave plugin.
Both are free for the first forty trial sessions, so it's easy to try out.
I wouldn't use the curves you supplied though, because they are way too messy.

Martin.

I am just looking at some options...because for all my work it starts and or go thru Moi at a certain point.

If you are talking V-carving...I use Vectric Vcarve and the new update v12 which is on my list to buy...there is new feature called sketch carving which will save you hours.

Tnx!
