Hi Neil, here is a strategy that may help:

Here's a couple photos of the guitar and the guy I built it for, John Acosta of the "Bee Gees Gold" show.

Great things!!

Congrats!!

Thanks Marco!

Here's the first 3D body done with the new machine - of course it will look better after finishing. Ruined a few pieces of cheap wood before getting the CAM portion correct. The neck was not cut for the contoured heel but rather a standard heel - will do the contoured one in the model shortly.

Latest guitar modeled in Moi - small body semi-hollow arch top coming soon.

Beautiful!

that's really nice. you seemed to have got the hang of MoI. you're website is nice too. i hope you have a lot of success.

Great work Neil! Something very satisfying about creating an object in MoI and bringing it to reality via CNC (and a lot of hand finishing :)

Amazing work and professional photo lighting.

Thanks everyone for the kind words. Can't take credit for the photo as the pictures are by a professional photographer who is also a customer.

Great advice - thanks!

Hi Neil,

> There is a guy selling tutorials on how to model guitars in Moi3D here: https://3dcncguitars.com/

That's great, I didn't know about this one! I've added a link from the MoI resources tutoriuals page.

That would easily be worth it to get very specific information on a complex area like this.

Still a novice - but have learned a lot via this forum about guitar modeling. When a little further along I'd like to share, in a concise file, the tips and tricks accumulated over the years from here so that others, interested in the area, will have a solid foundation to get started with and then expand on. Certainly can save the beginner some grief.

Here is an arch top made with a different program that was shared on a CNC web site - any ideas how one could do this with Moi?

Hi Neil, that one seems to be built in a "patch by patch" type method where some profiles were drawn in and several surfaces probably constructed using a sweep or network type tool. One problem though with this kind of patchwork method is it's hard to get a totally smooth result. For example this area has a sharp edge:





It tends to be hard to get really good quality smoothness using this type of approach. But it is overall a pretty difficult thing to model.

Often times something organic where you would need to do a patch-by-patch approach can be handled better by sub-d modeling instead of NURBS modeling for those areas.
