How do I make a curvature continuous fillet in SW?

Tutorial by Sudhir Gill
Small

Here is the tutorial and the file I used.

  1. Step 1:

    Start SolidWorks.

  2. Step 2:

    On Front plane in part mode make a sketch like this using spline.

  3. Step 3:

    Extrude it by height say 50mm.

  4. Step 4:

    Again enter front plane >> sketch and again a spline like this. And have a coincident relation with the end point of previous spline.

  5. Step 5:

    Extrude it by 50mm also.

  6. Step 6:

    Under surfaces tab choose fillet.

  7. Step 7:

    Select face fillet type.

  8. Step 8:

    For face set 1 select extrude-surface 1 and for face set 2 select extrude-surface 2. adjust direction to inside region.

  9. Step 9:

    Choose front view for better view of the fillet to be formed.

  10. Step 10:

    Click fillet options in fillet property manager.

  11. Step 11:

    Check curvature continuous. And you can see the change in fillet.

  12. Step 12:

    Change the fillet radius to 20mm.

  13. Step 13:

    Click OK and the fillet is formed.

  14. Step 14:

    Under Evaluate tab choose zebra stripes for tangency analysis. And zoom to the surface along the surface-extrude1 and the fillet. You can notice the continuity of zebra stripes.

  15. Step 15:

    Same goes for surface-extrude2.

  16. Step 16:

    Disable zebra stripes and you are done.
