Hi Phiro, the ReconstructCurve plugin has an option to build a polyline through the sampled points:

Thanks a lot Michael...

I use ReconstructCurve since many years but I never use it like this...
I always selected a curve (or many) then launch ReconstructCurve...
But I never launched it before selecting... and saw this possibility...
LOL

Thanks again !

Heck, I've done a lot of reconstructions in this days to make continuity of patches via Blender by using nurbs iso, generated from Moi3D surfaces of hull, if I had only knew this script before. I've used polylines over the CV of iso of each patch and joined with blender and imported in Moi3D as a SubD surfaces in order to avoid seam of surfaces.

:) Was on my site since more 12 years! :)

You have also this one maybe...
Convert a polyline, or polycurve, to a control point curve.
