Hi Karsten.

You're welcome!

@You : "...A quartz node in combination with a boundingbox for the range would also worth an Experiment..."

Perfect! This is exactly what I've thought while I was playing with this experiment.
An "automatic" range detection would be very very useful.

Is the same approach I have applied to my (almost done) new script "FilterCurveByLength", that I hope to publish soon,
where I calculate automatically the "min" and "max" range for filtering.

Cheers!
