Leaked texts of the Trans-Pacific Partnership agreement's “Intellectual Property” chapter confirm our worst fears: Big Content companies are pushing extreme copyright provisions in a secret trade deal that would put restrictive controls on the Internet.

I would add:

1.  Good curves lead to good surfaces, which lead to good models.  Invest a lot of time into your core curves.  They matter.

2.  Keep curve degree low.  The trade off is detail vs stability.  The more complex a curve, the more difficult it is to maintain a smooth curvature on that curve.  Less is more.  Consider using conics where you can.

3.  Strategy.

There are three basic approaches:

a.  Drape surfaces onto a wireframe skeleton

b.  Build basic surfaces, and over build them to trim back to one another

c.  Use combination of surfaces and solids to form shape, using surfaces as tools to manipulate the solid, replace face, trim, etc...

Think about the model and how it might change and where you need transitions.  Apply most robust method.

4.  Analyze surface quality frequently.  Poorly developed surfaces lead to unstable, problematic to manufacture models.

5.  The world is 4 sides.  Surfaces have a U and V two-dimensional representation.  Select a strategy that maximizes 4 sided patches for best surface quality and robustness.

6.  Avoid slivers, triangles and highly differentiated curves where possible.

7.  Preserve sharp edges and curves for finishing operations later on, except where a transition or the model requires a given curvature.

Great article!

Wow ! that's a lot of insight.
Thank you for listing so many important points to consider with surface modeling. These are very useful.

This is great!  I laughed, and really enjoy the song. 

Greets from the US.

Well done.

If you are using bifocal glasses, give this Kickstarter a close look.  I've been using a prototype for a while and it's just great!

The people behind this project have worked hard to make a great, effective product.  Consider backing this project for yourself or a friend.

Warning:  You may well end up wanting two of these, one for home, one for work.
Tom McKasson is raising funds for FocalPoint Monitor Stand for Bifocal Users on Kickstarter! If you wear bifocal glasses or readers while using your computer you've probably experienced a crick in the neck. Relief is here!

The idea of the Internet being a basic, paid utility type service is an important one.  Consider adding to President Obama's voice by calling the FCC:
