Tutorial 2: Fairing

http://www.cadfamily.com/a/CAD_CAID/Marine/Tutorial-2--Fairing_1639.html

1. Open your design from the previous exercise (with a design
window topmost, go to File | Open Design), if you already have a
design open, you will need to close this first (File | Close Design).
2. We now want to manipulate the design to increase the overall
fairness of the hull shape. The easiest way to ensure a fair surface is
to keep the control net as fair as possible, since this will effectively
amplify any unfairness in the surface. Try to keep control point rows
smooth, and in keeping with the shape of the buttocks and waterlines,
and keep columns as straight and evenly spaced as possible. This
should ensure that the surface remains relatively fair, and reduce the
need for further manipulation. Check your design in all views after
any major design changes.
