< But there could be some details that would be hard to get right in the script, like making sure that when you pick 2 curves that the points are going in the same direction on them instead of going in opposite directions.

If i make Trandform array /Curve with a point along a curve I give direction i want ? ;)
So not important
and each curve has the same numbers of points

< I'm afraid that it's probably going to be complicated enough that I can't just create it for you myself though, sorry.
No problem :)
