Hi Alex,
the I am using NodeditorPlus found here https://moi3d.com/forum/messages.php?webtag=MOI&msg=11614.1
I have played some more with the nod file and updated it in previous post.
I found it was better to join the curves and let the nod file separate them plus you can select more than one curve and it will separate them and you can step thro the curves with the number widget.
I was hoping to automate it rather than using the numbers widget to step thro to get the radii and length but at the moment cant do but have asked Mo_ te for help with this.
Cheers
Barry
