Follow a curve or line at constant speed

Hi All

I am trying to have a dot follow a line at constant speed. My problem is that the points on the line are not spaced at equal distance. So the dot move faster when the points on the line are further apart than when they are close.

any ideas? perhaps a completely different way of getting a point to follow a line.

Haven´t had a look at your patch. But maybe Arclength (3D generic) helps.

Cooool @bjoern :) just what I needed, thank you!

one more question, does someone know of a spreadable version of this?
I’d like to have lots of little lines grow, so basically a bin size pin would do wonders.
Just asking before I go into creating a spreadable version myself.
