    Create a Datum plane as shown above by entering the offset distance of 3 mm.

  7. Step 7:

    Create the sketch as shown below in the newly created DTM1 plane and click OK.

  8. Step 8:

    Pad (Extrude) the Circle created in previous step to the depth value of 25.5 mm.

  9. Step 9:

    Select the top face of the rectangle and create sketch as shown below with specified dimensions and click OK.

    Note: Use references tools in Profile group to make it simple.

  10. Step 10:

    Pad the previous created sketch with extrude depth value of 25 mm.



  11. Step 11:

    Select the face shown below and create a sketch with specified dimensions and click OK.



  12. Step 12:

    Create a pad as shown below with extrude depth of 14 mm.



  13. Step 13:

    Create sketch below with specified dimension by selecting the face as selected below.



  14. Step 14:

    Pad the sketch created in previous step with depth value of 6 mm.



  15. Step 15:

    Create fillets as shown below by selecting the edges with radius of 2 mm and click OK.

    Create another fillet on the edge selected before with radius of 1 mm.






  16. Step 16:

    Create the sketch as shown below by selecting the mid plane with specified dimensions.

    Note: Use Oriented Rectangle at 70 degrees from the axis with 7 X 14 mm dimension (use construction lines to make it simple)



  17. Step 17:

    Create a revolve section as shown below with reference the axis and click OK.


  18. Step 18:

    Create sketch as shown below with specified dimensions at the selected faces and pad backwards with a depth value of 8 mm.




  19. Step 19:

    Pattern the extruded part using Circular pattern taking instances as 4.




  20. Step 20:

    Create the sketches as shown below using 3D project options and using dimension constraints and create pad up to selected edges as show in images.




  21. Step 21:

    Create fillets with specified dimension r = 4 mm as shown below.

    Create fillets at this selected edge with r =1 mm.

    Perform fillet as shown below at the selected edges with radius of 3 mm.




  22. Step 22:

    Create fillets as shown below with specified dimensions on the selected edges with r =2 mm.

    Create fillets r =2.5 mm at the selected edges as shown below.





  23. Step 23:

    Create sketch as shown below and pad to a depth value of 9 mm.





  24. Step 24:

    Create the sketch on the same face which you created sketch in the previous step with specified dimensions and create a pad with depth value of 1 mm.





  25. Step 25:

    Pattern the extruded part using Rectangular pattern taking instances as 4 with a spacing of 3 mm.





  26. Step 26:

    Create Edge fillets on the selected edges with a radius of 2 mm.



  27. Step 27:

    Create a sketch as shown below with the help of 3D projection.



  28. Step 28:

    Create a pad selecting the above sketch up to 9 mm.



  29. Step 29:

    Select the above extruded part and pattern it using a Circular pattern.



  30. Step 30:

    Create fillets as shown below with r =0.3 mm.

    Create another set of fillets at the selected sections as shown below with r =0.5.



  31. Step 31:

    Create a plane as shown below.



  32. Step 32:

    Create a sketch as shown below with the help of projections. Take the width of Rectangle as 2 mm.



  33. Step 33:

    Pad the created sketch in reverse direction with a depth of 12 mm.



  34. Step 34:

    Create fillet for the selected edges with a radius of 0.5 mm.

    Create fillet for the selected edges with a radius of 1 mm.





  35. Step 35:

    Create sketch as shown below with specified dimensions and remove material using pocket option also create circular pattern of the holes.







  36. Step 36:

    Create sketch at the selected faces as shown below.

    Now using Pocket remove material with a depth of 25 mm.





  37. Step 37:

    Create sketch at the selected faces as shown below.

    Pad the selected sketch up to 0.25 mm.





  38. Step 38:

    Create fillet for the selected edges with a radius of 0.3 mm.


  39. Step 39:

    Create a plane at an offset distance of 2 mm as shown below.



  40. Step 40:

    Create a sketch as shown below with the help of projections.

    Pad the sketch up to 1 mm downwards and pattern the part using rectangular pattern.

    Mirror the pattern to the opposite side as shown in the figure.







  41. Step 41:

    Create fillets for the extruded parts with r = 0.3 mm.


  42. Step 42:

    Create a sketch as shown below.

    Using Pocket remove material up to 4 mm.





  43. Step 43:

    Create a sketch on the selected face and pocket it using up to last option.





  44. Step 44:

    Create a sketch and pocket the face with a dimension up to 20 mm.





  45. Step 45:

    Create a sketch as shown below, using pocket remove material up to a depth of 9 mm and pattern that using Circular pattern as shown below. 







  46. Step 46:

    Create fillets to the patterned holes with a radius of 0.3 mm.


  47. Step 47:

    Create a sketch and Pad it up to 14 mm equally on both sides.





  48. Step 48:

    Create a sketch as shown below and pocket using up to last.





  49. Step 49:

    Create fillets for the selected edges with a radius of 0.3 mm.


  50. Step 50:

    Create a sketch as shown below and pocket it up to 15 mm.






  51. Step 51:

    Create a sketch as shown below using mirror option and remove material using pocket.





  52. Step 52:

    Create a sketch as shown below and pad it up to 7 mm.





  53. Step 53:

    Create fillets for the selected edges with a radius of 0.5 mm.


  54. Step 54:

    The final component looks like this.
