Tutorial - Modeling Spring in AutoCAD using extrude face?

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.
