Tutorial - Modeling Bolt with terminating thread in Creo Elements aka Pro/E?

Here is the tutorial.
-
Step 1:
Sketch >> Top plane.
-
Step 2:
Draw a circle of 20mm dia.
-
Step 3:
Extrude it by 100mm.
-
Step 4:
Sketch >> Top face.
-
Step 5:
Draw a polygon with 17mm radii circle.
-
Step 6:
Extrude it by 10mm.
-
Step 7:
Sketch >> Right plane.
-
Step 8:
Take reference with the edges and draw a triangle.
-
Step 9:
Revolve it about the center axis with remove material.
-
Step 10:
Chamfer the lower edge with 45 x D (D=2.50).
-
Step 11:
Insert >> Helical Sweep >> Cut.
-
Step 12:
Click Done.
-
Step 13:
Select Front plane.
-
Step 14:
Click Default.
-
Step 15:
Now draw a center line about the vertical axis.
-
Step 16:
Draw another line and spline tangent to it.
-
Step 17:
Exit the sketch. Now input the pitch value = 2.50.
-
Step 18:
Click OK and now draw the section. Draw a Iso triangle with 2.4mm at 3mm from axis.
-
Step 19:
Exit the sketch and define the cut-side be inside of sketch.
-
Step 20:
Click OK and the feature is generated. We can see the thread ended in regular fashion.
