In the re-writing, the template/sample file was re-made:
but it is so prosaically simple and naïve, that the matching DXF:
when imported into a typical CAM tool:
cannot be readily assigned toolpaths to make the diagonal/sloping cut.
A reasonable approximation could be made by deciding how many segments one would be willing to cut/assign toolpaths for, reducing the line by that number:
Done
and duplicating and aligning and assigning toolpaths to cut each copy to the desired depth:
and then assign each line segment after the first with a suitable toolpath:
incrementing as we go along:
until we arrive at:
which once cut may be easily cleaned up with a suitable tool.
