Hi Joe,
So can Carvewright create a toolpath from this?



If so, then I was suggesting making curves from those sections that would look like this




Then when you cut each curve, it would cut at its own depth and create a "step".



This is the step I was talking about.




If the part is 1 inch high, and the spacing of each level is .8 and you use a .5 ballnose cutter, then the ridges in between each level will be at some hight. The more levels, or curves, the finer the step and the smoother the surface (The longer the cut time). Less curves and levels is faster cut time, then you just pull the piece off the machine and do a quick sand or grind to smoth the toolpath edges away.

It's not a formula I mentioned, just a decision to be made on how you want to cut it.

Also, after doing some experimenting with this to show you, it becomes more apparent that it's harder to implement than I'm making it sound. It would require working the curves a bit to get a good profile. May be better off just going the hieghtmap software route.
