Hi Neil,

I don't have a neck example but I think the attached models I built may illustrate the use of "Network".

I use "curve network surface" or "network" all time for surfaces that need to come together under very specific dimensions, with clean transitions from one surface to another. Automotive design, lots of surface transitions, same idea.

The volute is a good example. Couple surfaces coming together at that one intersection. The English guy in the YouTube video also used "Curve Network Surface" (as he used Rhino 3D) or "Network" (in MOI) for his volute.

As a guitar player and Industrial Designer...I'd prefer to specify the volute surface dimensions rather then just "blend" them together.

Just my .02 cents.

Hope that helps!

Mat
