If your Design is 2.5D then you can cut your design in openscad with "projection(cut=true)". That will give you a DXF that can be fed into "dxf2gcode". This works for anything with planes parallel to Z (on a mill), but not for angled surfaces. 3D operation with pycam works, but produces most inefficient toolpaths. I was told that FreeCADs "Path"-Workbench is quite usable, but I have never done a piece on myself.
