[Closed] Spline shape Select

Sorry for the misleading and not clear direction I was going with this.
Taking into the account the splines radius I wanted to move along the splines path in order of the knots, collecting any objects whose center(pos) falls within the given radius of the point3 on the spline. Resulting in a collection of objects who fall on the path of the spline(w/radius)

does that make sense?
I can show an image to show what I’m after, and the code above does exactly what I want. It needs a bit of clean up but its there.
