Technical Assistance: Stephen Landrum, Senior Consultant
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.2
Axis = Z
Pitch = 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 = Line
Sub-Type = With reference surface
Guide Curve 1 = Helix 1
Reference Surface = XY Plane
Length1 = 20mm
Length2 = 20mm
Select “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 = Normal
Projected = Sketch 1
Support = Swept Surface Sweep.1
Select “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.1
Cutting Element = Project.1
Select 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 = 1mm
Second Offset = 1mm ( Because we
have elected to add material to both
sides )
Object to Offset = Split.1
Select “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.
