Tutorial: How to make a springy spring

I got another idea for making it!
follow the procedure below

  1. Step 1:

    First of all draw a circle on top plane

  2. Step 2:

    use a helix/spiral commend and give that circle to it and give parameters in below:

  3. Step 3:

    Go to reference geometry and define a plane using Helix and its start point

  4. Step 4:

    In that plane sketch a line for further reference!

  5. Step 5:

    Go to reference geometry and define another plane using previous plane (step 3) and the line in step 4 as below:

  6. Step 6:

    In this plane sketch the profile you want to sweep as below:

  7. Step 7:

    Now sweep that profile along Helix with options illustrate in the figure:

  8. Step 8:

    hide plane and sketch
    Here it is your final model!

  9. Step 9:

    And here is a rendering
