Building parametric guitar fretboards in Onshape - including Fanned Frets!!
Fretboards (indeed guitars) are beautiful things combining math and music and aesthetics... The pattern that drives the position of the frets is simple enough: position from nut = scaleLength - (scaleLength / (2 ^ (i / 12)))
But how do you implement this in CAD?
Onshape makes it easy, and by adding parametrics, configurations, decals, expressions to capture logic, and more... it's a really nice experience!
But there's more in this video... Fanned Fret guitars are fascinating things, and the fretboard looks super cool. Come with me on a journey to examine all this.
