this might be possible using kangaroo in gh, @DanielPiker ?

What software is used in the video?

The polyline looks like a rebuilt contour or polyline from a plane / mesh intersection.

not as shown, but you can project a curve onto a mesh with history on the original curve then edit the original curve to see it update it on the mesh.

Geomagic Design X

it may be implement as polyline, but could be export as NurbsCurve

Oh I wish I had this!
