Tutorial - Modeling Helmet in SolidWorks?

Here is the tutorial.
Step 1:
Top plane>>Sketch.
Step 2:
Draw this profile. The lower one is made using spline and fit spline tool.
Step 3:
Extrude it at Draft.
Step 4:
Right plane>>Sketch.
Step 5:
Draw a semi-circle.
Step 6:
Revolve surface it.
Step 7:
Right plane>>Sketch.
Step 8:
Draw a spline.
Step 9:
Trim the lower area.
Step 10:
Lofted surface.
Step 11:
Select the edge of the upper surface.
Step 12:
Right click and selection manager.
Step 13:
Select all the lower edge.
Step 14:
Click ok in selection toolbar.
Step 15:
Now Tangency to face.
Step 16:
Right plane>>Sketch.
Step 17:
Draw a spline like this.
Step 18:
Trim off the lower area.
Step 19:
Right plane>>Sketch.
Step 20:
Draw a profile using spline. 3 splines are used having tangent relations.
Step 21:
Trim the surface using spline.
Step 22:
Knit surface.
Step 23:
Select all surfaces and check merge entities and uncheck gap control.
Step 24:
Thicken the surface.
Step 25:
And we have basic body of helmet.
thank you so much for this tutorial. it was very helpful.
