If the path is only 2D, then use “Bend” on an Helix.
1: Create Helix + Path
2: Increase number of points on path (<- important. The more points the better for bend)
3: Bend Helix to path (scale if needed)
4: Add curves to ends of Helix for connection. Weld them
5: Add thickness to Helix.
It would be nice to be able to slide the points along the line without distorting it ....
Fare scorrere il punto lungo la linea senza deformare la linea…...
