Points I forgot in the video, they'll make it more clear.

1 "outer edges" mean outside diameter
2 for surface sweep, there are 2 different sketches on same plane,
3 you can also use "up to vertex" for surface extrude, and select the top point of the line in the sketch defining the height of the spring
