Ok Fernando, I finally came up with something, not sure it's directly useful for you as I used Visual Mill for the cam program. However, it simply is the polylines drawn to designate the toolpath, saved in dxf, then in VM, I selected 2.5d>Engrave, with 'on condition', and this engraves the lines directly, including the slope around the arcs. Idont have artcam, but hopefully it has an Engrave option to do this.
I'd never used the engrave before, and only played with the 2.5d a small amount.
