Luthiers rejoice - Songbird is
a parametric Multiscale Fretboard Generator for Rhino. You can use it
to generate fanned fretboards for guitars, mandolins, bass guitars,
ukuleles or whatever instrument you want to cook up. It also generates
standard single scale, non fanned fretboards just as easy, simply input
the same scale length for both first and last string. The plugin exposes
a single command called "fretboard".
