Sorry everyone, the webhosting went with the hacking here sometime I will get it up on my blog It will take a while since I have to redo everything to the blogs format. That or when I get a new host.

BTW this work on curved surfaces see the blue addendum part of the tut. Its all the same idea its just when you say have a rounded corner you got to make sure you have enough geometry there to not segment when you extract the corner. Or you can chamfer it round AFTER you do the extrusions depending how round you want it.
UPDATE NEW URL
This is on my blog look under tutorials if you do not see it on the front page.
Each day we draw closer to the end.
