How can I model a violin headstock in Grasshopper?

I am a beginner in Grasshopper. How can I model a violin headstock in Grasshopper?

Hi,

In my opinion that would only really make sense, if you wanted to parametrise it, meaning control for instance the height, width, depth, and maybe other facets of the design to be able to produce more than one violin headstock model.
Otherwise, I’d simply model it by hand. This will certainly be much quicker.

That said, if you still want to give it a go in Grasshopper, you should probably first mentally break down the defining parts of the overall geometry and think about what you want your parameters to control.
A second step would then entail recreating for instance your hand modelling workflow of the same geometry in Grasshopper, but basing it on the defined parameters. It’s best to start simple, maybe in two dimensions, with planar curves that by lofting or extruding later can make up parts of the headstock.

Imagine someone asking this question about any other cad: how do I design a violin headstock in Rhino, SolidWorks, blender etc. I mean you’re asking how to do many hours of work? Not really sure what kind of answer you’re expecting.

That said, GH isn’t really the tool for something like this. Yes it’s possible, but unless you have a very good reason to do this in GH you’re better off modelling it in Rhino.

How? Start somewhere and ask for specific help when you get stuck on something.

There are a number of guitar headstock shapes in Rhino on YouTube, done by guitar makers. I expect those may work to show how it is done.

Here is a quite simple one, but there are many more: https://www.youtube.com/playlist?list=PLtQDVRMUYN-yjackAgTZnGj1CbqZDtmsV

Guitar Neck Model - I'm close

I’ve created a neck model for the guitar project I’m working on, and technically it is functional, but I’d like to refine and improve a few things. Please see the items below: I’ve basically built out a wireframe and used NetworkSrf and PlanarSrf to skin it, but the areas where the neck shaft flows into the headstock has some rippling and angular facets. I would like to understand how to blend the geometry in a little better for a smoother transition: [Screenshot 2024-07-17 at 8.22.37 AM] […

The parametric headstock modeling can be easily modified into multiple headstock models with slightly different details, just as you said, to control the height, width, etc. If I just want to build a headstock, I have already done it in Rhino. Thank you for your tips, thank you!

I have already realized the simple construction of a guitar head model in Rhino, thank you!

Thanks for the guitar modeling link, thanks!

Hi @yunyu_qu

If that is your already modeled headstock in Rhino then…
The first step is to bring it to the the origin 0,0,0. Orient it to be either lying down or standing.
Then in Gh reference that object and begin playing with the basic tools in Gh for modeling and size finding.

You can explode the model, see how many surfaces there are, their sizes, their linework. then come to grips with how you are going to re-make those surfaces into a Grasshopper definition. You will have to figure out how you move the surfaces to their proper locations and how to join everything. Since you modeled the headstock you might have to think of ways of doing some of those same modeling operations that you used in Rhino into GH(Grasshopper).

This is kind of complex project because you might need a few modules in your GH definition, like the volute and the neck loft etc. the hole placements and cutouts.

@yunyu_qu, you might search for Bernoulli spiral and read into the art of the violin design
