1. From the Start menu select “Mechanical Design” / “Wireframe and Surface Design” workbench.

2. In the “New Part” dialog box, enter the Part Name “Blade”.Select to activate the “Enable Hybrid Design” and the “Create Geometrical Set” options. Select “OK”.

3. Select from the “Wireframe and Surface” toolbar / Point icon. 4. In the “Point Definition” dialog box, create a “Point” at X= 0, y= 0, z= 0.

Selecting “OK” creates Point.1.

5. Select from the “Tools” toolbar / Axis System icon.

6. Select “Point.1” as the Origin and select “OK”.

7. Select from the “Wireframe and Surface” toolbar / Point icon. 8. In the “Point Definition” dialog box, create a “Point” at X= 0, y= 20mm,

z= 0. Selecting “OK” creates Point.2. This point determines the “radius” of the Helix.

9. In the same toolbar select “Helix” Icon. This icon is in the Sub-toolbar, Curves. (You can “Toggle” using the Black Arrow down to the right of the Spline icon to get this embedded icons, or drag to pull and see the full toolbar)

10. In the “Helix Curve Definition” dialog box, enter the following:Starting point = Point.2Axis = ZPitch = 250mm “You can Play with this Value”Height = 100mm “You can Play with this Value”Select “OK”. (You can also “Preview” the Helix before selecting OK)

11. Create a “Sweep” Surface.

12. Select from the “Surfaces” toolbar / Sweep icon. 13. In the “Swept Surface Definition” dialog box, enter the following:

Profile Type = LineSub-Type = With reference surfaceGuide Curve 1 = Helix 1Reference Surface = XY PlaneLength1 = 20mmLength2 = 20mmSelect “OK”.

14. The Swept Surface.

15. Create a “Sketch” on the “yz plane”. Select the “Sketch” Icon and Select the “yz plane” in the PPR tree.Note: You can also “Drag” the Sketch Icon by Holding (Left Mouse Button) LMB over the Sketch Icon and “Drag” onto the YZ Plane either in the PPR tree or the “yz plane” geometry on the Axis System.

16. Select from the “Profile” toolbar / Spline icon. 17. The “Sketch tools” dialog box appears. For the first point, type in

H = 25, V = 0.

Hold LMB (Left Mouse Button Down) and precede CCW (Counter Clockwise) for Second Point, or type in the Sketch tools dialog box 29, 26. The Third Point, 14, 37, and the Fourth Point, 6.5,0 (Double Click with LMB on this last point to complete Spline, or if you are using the Sketch tools toolbar deactivate the icon to finish the Spline.

18. Continue to “Close-Out” the Sketch.

NOTE: This is optional BUT it is always good practice to have a “Closed Curve”.

19. Select from the “Wireframe and Surface” toolbar / Line icon. Select the last point in the Spline. This will create the 1st point in the Line AND 5th

Point. 6.5, -10.0 to create a Vertical Line. You can also type in the values in the Sketch tools dialog box.

20. Create another line, Point 5 to Point 6, 25, -10. Create the last Line to “Close” to the 1st Point of “Spline.

21. Check that the “Sketch” created is a “Closed Curve”. In the Main Menu Select

“Tools / Sketch Analysis” (VERY

Important that the Curves are “CLOSED”).

22. The “General Status” is all check passed, and the Detailed Information states “Closed”. Select “Close”.

23. We will now “Project” the “Closed Curve Sketch” on to the Sweep Surface.

24. Exit the Sketch workbench and return to the Wireframe and Surface Design workbench using the “Exit” icon.

25. Select from the Wireframe toolbar / Projection icon.

26. In the “Projection Definition” dialog box, enter the following:

Projection Type = NormalProjected = Sketch 1Support = Swept Surface Sweep.1Select “OK”.

27. Now you can “Hide” Sketch.1. Select “Sketch.1” with LMB and with RMB (Right Mouse Button) Select “Hide/Show”.

Note: The Icon in the PPR tree next to Sketch.1 color has changed to

“GREY”.

28. We will now “Split” the Projected Contour from the Swept Surface.

29. Select from the “Operations toolbar” / Split icon. In the Split Definitions dialog box, enter the following:Element to Cut = Sweep.1Cutting Element = Project.1Select the bar “Other Side” ( Necessary to get the Desired Shape for this example. )Select “OK”.

30. The Completed Blade.

31. We can now ADD “Thickness” to the Blade Surface. 32. From the Main Menu select “Start / Mechanical Design / Part Design”

workbench. Make sure that the “Part Body” in the PPR tree is “Defined in Work Object” (You will see Part Body Underlined to note that Thickness will be Under Part Body in the PPR tree). To do this, Highlight the “PartBody” in the PPR tree, and RMB for the contextual menu. Select “Define In Work Object”.

33. Select from the “Surface based Features-Extended” toolbar / Thick

Surface.

34. In the Thick Surface Dialog box, enter the following:First Offset = 1mmSecond Offset = 1mm ( Because we have elected to add material to both sides )Object to Offset = Split.1Select “OK”.

35. RMB to Hide the Split, and the Helix elements.

36. We will now create a “Tritangent” Fillet.37. Select from the “Dress-Up Features” Toolbar in the “Fillets” sub-toolbar

(black pull-down arrow) / Tritangent Fillet icon.

38. In the “Tritangent Fillet Definition” Dialog box, enter the following:Faces to Fillet : Select in the 3D geometry window the Opposite Sides of the Solid Element ( 2 Elements )Face to Remove: “Select” the Center Surface Between the two surfaces ( Purple-Highlighted )Select “OK”.

39. The Completed Blade.

40. We will now “ADD” a Material – Brass.

41. Select the “Apply Material” Icon.

42. In the “Library” dialog box, select the Metal tab. Select ”Brass”.

43. Select the “PartBody” from the PPR tree, Select “OK”.44. To view the Brass on the Blade, from the “View” toolbar select the Sub-

toolbar “View Mode” select the “Customize View Parameters” Icon. (NOTE: View is also in the Menu Bar at the top of the software, and can be another alternative. View/ Render Style / Customize View.)

45. The “View Mode Customization” dialog box appears. In the “Shading” section, select “Material”, and “OK”.

46. The Brass Blade.

47. Moments of Inertia.48. Select ”PartBody“ from the PPR tree.49. Select from the “Measure” Toolbar / Measure Inertia icon. 50. Note: Volume, Area Mass, Density and the Center of Gravity.
