Tutorial - Modeling Flower in Creo Element aka Pro/Engineer using Surfacing method 1?

Here is the Tutorial.
-
Step 1:
Sketch >> Top plane.
-
Step 2:
Draw a spline. Exit the sketch.
-
Step 3:
Sketch >> Front plane.
-
Step 4:
Draw a spline. Exit the sketch
-
Step 5:
Sketch >> Front plane.
-
Step 6:
Use the spline (i.e. convert). Exit the sketch.
-
Step 7:
Sketch >> Top plane.
-
Step 8:
Draw a identical spline to that in 2nd step.
-
Step 9:
Now we have 4 splines.
-
Step 10:
Select one spline on top plane and one on front plane and then goto Edit >> Intersect.
-
Step 11:
This creates a 3D curve for these splines. Repeat the same step for other two.
-
Step 12:
Insert >> Boundary blend.
-
Step 13:
Hold CTRL and then select both curves.
-
Step 14:
Insert >> Advanced >> Vertex Round.
-
Step 15:
Select the surface.
-
Step 16:
Hold down CTRL and select both vertex. Press middle mouse button.
-
Step 17:
Now enter the trimming radius.
-
Step 18:
Now hide the interest1 and intersect2.
-
Step 19:
Sketch >> Top plane.
-
Step 20:
Draw a circle.
-
Step 21:
Extrude it.
-
Step 22:
While selecting the leaf goto Edit >> Trim.
-
Step 23:
Select the circular surface as the trimming object.
-
Step 24:
Direction of keeping be outside.
-
Step 25:
Hide the extrude surface.
-
Step 26:
Select the surface and then goto Edit >> Pattern.
-
Step 27:
Pattern it about axis 6 times.
-
Step 28:
Select the surface trim and then goto Edit >> Pattern.
-
Step 29:
It will automatically pattern for reference. Click OK.
-
Step 30:
Thicken the surface.
-
Step 31:
Select the thicken surface and then Edit >> Pattern. Same settings and click OK. All the surfaces will be thickened.
-
Step 32:
Sketch >> Top plane.
-
Step 33:
Draw this sketch.
-
Step 34:
Revolve it and we have the flower body.
