The following is my plotter art workflow with Unity.

1. On Unity, render a monochrome line-art image using the Recolor (contour line) effect. The resolution of the image should be high enough. I usually use 2400x3840.

2. Rotate it if needed. convert temp.png -rotate 90 render.png

3. Convert it into SVG using autotrace. autotrace --centerline --output-format=svg render.png > plot.svg
