Tutorial by Sudhir Gill
Small

Here is the tutorial.

  1. Step 1:

    Top plane>>Sketch.

  2. Step 2:

    Circle of 20mm dia.

  3. Step 3:

    Extrude it by 100mm.

  4. Step 4:

    Top face>>Sketch.

  5. Step 5:

    Draw a polygon of 32.5mm circle.

  6. Step 6:

    Extrude it by 10mm.

  7. Step 7:

    Top face>>Sketch.

  8. Step 8:

    Draw a circle of 32.5mm dia or tangent to the side of polygon.

  9. Step 9:

    Extrude cut it by flip side to cut at 60º draft.

  10. Step 10:

    Same cut with lower side of polygon.

  11. Step 11:

    Chamfer the bottom edge by 2mm.

  12. Step 12:

    Top plane>>Sketch.

  13. Step 13:

    Select the outer edge and then convert entities.

  14. Step 14:

    Make a helix defined by Height and Pitch with height=80mm, pitch=2mm Clockwise.

  15. Step 15:

    Reference Geometry>>Plane.

  16. Step 16:

    Offset the top plane by 80mm or by coincident to the helix end point.

  17. Step 17:

    Plane1>>Sketch.

  18. Step 18:

    Convert the sketch5 under previous helix.

  19. Step 19:

    Create a helix with height=10mm, pitch=2mm clockwise at taper helix 30º outward.

  20. Step 20:

    Right plane>>Sketch.

  21. Step 21:

    Draw a triangle using polygon tool.

  22. Step 22:

    Sweep cut the triangle about helix1.

  23. Step 23:

    Select the end face of the sweep cut and then sketch.

  24. Step 24:

    While selecting the face click convert entities.

  25. Step 25:

    Sweep cut that sketch about helix2.

  26. Step 26:

    And we have terminating threads.

  27. Step 27:

    Rendered Image.
