Someday, when Michaels done working a bit and taking a break, Maybe we can see a page with links of "Michaels Favorites". I bet it's a wealth of Knowledge!

>one thing to keep in mind is that sub-d surfaces can also have lumps and buckling in them in various situations as well

Very true. I guess the difference is that you can add some more edges or rearrange your sub'd cage and do some point tweaking to remove the lumps and buckles. With nurbs there are just too many points on the surface to do this. Nurbs however are certainly great for the more mechanical type parts.

The equivalent for NURBS is more about doing a similar process on your original curves to smooth them out or simplify them and recalculating the loft or sweep, rather than working on the NURBS surface directly.

But one thing that can make this difficult is if you're trying to do a "reverse engineering" type task where you're trying to very specifically control the curves to match some existing blueprint. That has a tendency to lead you to put in more points or more curves, it can kind of lead you away from a simple curve setup...


> Nurbs however are certainly great for the more mechanical type parts.

Yeah for those things you use the "even more traditional" and fundamental NURBS tools such as extrusions, revolves, and booleans which are pretty much immune to buckling or wiggling type problems.
