Route lab

I made this input as bad as I could: chains cut into pieces and shuffled, some drawn twice, a circle with 1 440 points. That is what a quick generative sketch usually hands you. Switch the passes on and off and read what each one buys, in paths, points, pen lifts, travel and minutes. What you see is what the pen gets.

deduplicate — drop paths drawn twice merge — rejoin chains whose ends touch simplify — fewer points, same shape (0.05 mm) clean — remove zero-length paths strategy show pen-up travel
