That's weird, let me know what you get on that side, I've just checked
by running the code here and I'm getting uniform parametization on the
resulting curve as best as i can tell? On the original example I posted,
my curve had 6 spans, and a min/max of 0-10.537 and the rebuilt was 0-1.
I just tried with a straight line (all EPs on the x axis), and
everything *looks* uniform and 0-1 as far as i can tell, but yes, let me
know how you go - would be curious to know what's happening.

Incidentally i dont suppose you know how to change the parameterisation
of a curve. i need it to be going from 0 to 1 between each of these edit
points. So i can add more points at specific positions in between with
the insert knot curve command.

The points of the curve in world space change slightly. I need them
