Square Spring Tutorial,, SolidWorks 2013,, HD
rewind as many times! ask questions if you get stuck! learn and spread! it should be for the good of all! :)
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
