Although CAD is only a hobby for me, I did study design in school and consider myself pretty good at CAD design. However, I have been completely unable to model the heel and neck of an acoustic guitar. I am using Rhino v.3 and just seem to have too many curves to define all the compound surfaces.
I can easily model all the countours: In x plane you have the two tapered lines that represent the edges of the fingerboard and the arch that is the top of the heel cap; in the y plane you have the mirrored curves of the heel cap to fingerboard (like the cross-section of a ship) and arches that are the cross-section of the neck; and finally in the z plane you have the flat of the fingerboard and the curve that is the taper from the apex of the heel cap to the apex of the neck cross-section.
All these profiles blend smothly and seemlessly into a shape that is reminicent of a baseball bat that has melded into the bow of a ship. How, has proven beyond me.
Is there anyone who has successfully modeled an acoustic guitar neck and heel? Feel like proving to the world you superiority by sharing how you did it?
