Looking for a method to direct milling on the z-axis contour

[jsclownfish]

Is there a method to direct an 'engrave' method on an irregular Z-axis in 2D or 3D contour?  For example if I want to generate a tear drop shape in the cylinder by decreasing the depth of a ball end mill.  I typically use 2D contour to engrave on the surface of the cylinder, but this involves changes in the Z-depth.

Thanks,

Jon

Use 2D trace, it will follow the contour in XYZ

there's limitations to how steep of curvature you can machine without gouging but it looks like it would work on your file
