Here is the tutorial.

1. Step 1:

   Start AutoCAD.
   

   

2. Step 2:

   Draw a circle.
   

   

3. Step 3:

   Draw a line bisecting the circle in half.
   

   

4. Step 4:

   Select trim tool. Select all.
   

   

5. Step 5:

   Trim the lower half.
   

   

6. Step 6:

   Erase the line. Now use mirror command and select the circle.
   

   

7. Step 7:

   Mirror it along the arc end points.
   

   

8. Step 8:

   Use viewpoint command and enter 1,-1,1 or choose SE Isometric under view menu.
   

   

9. Step 9:

   Rotate3d and then select the half circle.
   

   

10. Step 10:

    Select Y-axis.
    

    

11. Step 11:

    Select the end point of the arc and rotate it by 5º.
    

    

12. Step 12:

    Repeat the same step for the other half.
    

    

13. Step 13:

    Rotate it by -5º.
    

    

14. Step 14:

    Copy command and then select both arc.
    

    

15. Step 15:

    Multiple type copy. Select the lower end point as the base point.
    

    

16. Step 16:

    Selct the upper point as target point.
    

    

17. Step 17:

    Repeat the same step and we have helix.
    

    

18. Step 18:

    Change the UCS about X at 90º.
    

    

19. Step 19:

    Draw a circle at the end point of the helix.
    

    

20. Step 20:

    Extrude command and then select the circle.
    

    

21. Step 21:

    Right click and then select path.
    

    

22. Step 22:

    Select the helix arc as the path and the part of the spring is generated.
    

    

23. Step 23:

    Modify>>Solids Editing>>Extrude faces.
    

    

24. Step 24:

    Select the face of the helix.
    

    

25. Step 25:

    Right click and then path.
    

    

26. Step 26:

    Select the arc.
    

    

27. Step 27:

    Repeat the same step for the rest of the helix part and the spring is generated.
