How to Duplicate(/Store) a Spline?

Hi, I’d like to know if it’s possible to duplicate a spline. I have a function building a spline from point A to B and I’d like to store it in another one, so that it is
possible to generate a certain number of splines in advance before they are used.

I tried Imgur: The magic of the Internet but since i’m a beginner i bet i miss something.

There is a bug in the set spline point position node. That will not work currently. This bug has already been reported and is being reviewed.

Hi, I’m curious about the exact same question. Was there a better solution that Google did not show me? Thanks.

My additional question is, are the locations of the spline points enough? I see there are also enter tangent, leave tangent, roll, etc, at a spline point. Should they also be saved/duplicated to rebuild a spline?
