Admittedly, this is an old tutorial, but around the 39:45 mark, Andrew Price uses a Curve > Path to make a coiled BezierCircle to follow it. He does it by holding Ctrl + left clicking. The bottom of the spiral stays where it is whilst the top follows the path.
I can’t get this to work at all. Whenever I try to do the same, the entire coil just moves up and follows the path. Does anyone know how I can get it to work properly or offer a similar method? Thanks.
