Hi Scott, just a few more notes on what you asked:

> Blending the edges didn't work.

Blend creates a new surface in the empty space between some edge curves. In your case you've got all the pieces touching with no empty space between them, so there's no room available for a blend surface to be created, that's why it would not do anything for you.

See here for some examples on how you would have things set up for doing a blend:

> Trying a Boolean didn't work wither.

Booleans only intersect objects with one another to cut away parts. Similar to Join, Booleans will not alter the geometric shape of a surface, they will only alter trimming boundaries to cut away some more areas of surfaces.


Like I mentioned previously, really this kind of project with semi-organic type forms does not tend to leverage the best strengths of NURBS modeling - if you're already comfortable doing sub-d modeling then doing things that are more sculptured in shape and semi-blobby-ish without much 2D profiles to them will tend to be better done in your sub-d modeling program.

Models that have more 2D design elements from them and things like holes and cut away areas will be the kind of stuff where NURBS modeling becomes much more useful for you probably. The particular model that you've targeted here is not in that kind of category though.
