3. ### Step 3:

Exit the sketch. Reference Geometry >> Plane.

4. ### Step 4:

Offset the top plane by 80mm.

5. ### Step 5:

Plane1>>Sketch.

6. ### Step 6:

Draw a circle of 50mm dia.

7. ### Step 7:

Select Lofted surface tool under surfaces tab and select both profiles.

8. ### Step 8:

Planar surface tool under surfaces tab.

9. ### Step 9:

Select the upper circular edges.

10. ### Step 10:

Front plane >> Sketch.

Draw a line.

12. ### Step 12:

Exit the sketch and then Curves >> Project curve.

13. ### Step 13:

Select the line and the face.

14. ### Step 14:

Top surface >> Sketch.

15. ### Step 15:

Draw this entity using rectangle and then fit spline tool.

16. ### Step 16:

Exit the sketch and then Select Swept surface tool under surfaces tab.

17. ### Step 17:

Select the spline as the profile and curve as the path.

18. ### Step 18:

Reference Geometry >> Axis.

19. ### Step 19:

Select Top plane and Origin.

20. ### Step 20:

Circular pattern.

21. ### Step 21:

Select the swept surface as the body to be patterned about axis 6 times.

22. ### Step 22:

Trim surface tool under surfaces tab.

23. ### Step 23:

Trim type be mutual and select all surfaces to trim. Under remove selection select all outer surfaces with swept surfaces.

24. ### Step 24:

Click OK and the trim is performed.

25. ### Step 25:

Thicken tool under surfaces tab and select the surface. Thicken it inside.

26. ### Step 26:

Top face>>Sketch.
