Hi all,

What is the best way to insert a point in a curve, when I know the uvw (well, only u as it's a curve) position of the point I want to create.

Thank you!

carve sop? it's not hugely procedural (its a pain to control it from attributes, drive different curves with different cut points), but at a basic level does what you're asking.

If you don't want to venture in vex, just merge the points in a single geo, then use the Sort Sop to sort their index by attribute ("u" in your case), finally use the add sop to connect them together again by index.

I use this trick all the time to connect scattered point on a line.
