Tutorial - Basic surface modeling of mouse in SolidWorks?

Here is the tutorial.
Step 1:
Start SolidWorks in Part Mode.
Step 2:
Front Plane>>Sketch and draw this entity using spline.
Step 3:
Now offset front plane by 30mm in both directions.
Step 4:
The planes are generated.
Step 5:
Plane1>>Sketch.
Step 6:
Draw a spline.
Step 7:
On plane2 Sketch the same entity using convert entity tool.
Step 8:
Under surfaces tab choose boundary surface.
Step 9:
Select the sketch in order and click OK.
Step 10:
Top plane>>Sketch.
Step 11:
Draw two symmetrical splines.
Step 12:
Trim the surfaces using those splines.
Step 13:
Top Plane>>Sketch.
Step 14:
Draw a spline like this one coincident to end point of surface.
Step 15:
Under surfaces tab choose lofted surface.
Step 16:
Select the edge and sketch and adjust the connector.
Step 17:
Now mirror the lofted surface body to other side
Step 18:
Under surfaces tab choose filled surface.
Step 19:
Select the bottom edges to form a filled surface.
Step 20:
Top plane>>Sketch.
Step 21:
Draw a spline and offset it by 0.25.
Step 22:
Trim the enclosed surface.
Step 23:
Again Top plane>>Sketch and draw a box symmetrical along horizontal axis.
Step 24:
Trim the enclosed region.
Step 25:
Top plane>>Sketch.
Step 26:
Make an ellipse.
Step 27:
Offset the button faces to inside.
Step 28:
Trim the faces using ellipse like this.
Step 29:
Top plane>>Sketch.
Step 30:
Make this profile.
Step 31:
Trim the bottom surface.
Step 32:
And we have the basic surface of the mouse body. It can be done more better if done with extra care.
Step 33:
The rendered image.
