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.

Hi Neil, so this surface is planar so that's probably a good one to construct first from planar profile curves:



Then this area here:



I'd probably try making an extended sheet something like this using Sweep or Network:



Then that would get trimmed by a profile curve like this:



And then these areas would be done with a Construct > Blend.



You could get a large portion of it built like that but then the rounded tip protrusion like spots will be the most difficult to do well.

Hi Neil, so this method would go something like this:

Planar curve here - build a surface from it using Construct > Planar.



Another planar curve on the interior like this:



Cross sections running in this direction, slightly curved:



Construct > Loft through those to make this type of extended surface:



Trim the loft with the interior curve:



Trim edges with lines to break them:




Select edges and do a Construct > Blend:








That would be a good way to start out I think getting an initial chunk of it done.

Then probably the next steps would be to build these strips that rise up from the planar base level:

Then it's going to get a bit tricky but maybe this kind of blend:

Fantastic - thanks Michael! This method looks much better than the patchwork. That's an excellent start to getting a handle on this. Have no experience yet with subD (although did download Rocket as you suggested). Thanks very much for the tips to get rolling. Here is another arch top from the same guy - not really crazy about this arch top - it's a bit too flat on the top. Tried to attach the file - but am out of space. If anyone want's it let me know. Really like the dimensions in V4.

Hi Neil,

re:

Well we'll probably arrive at some patch-by-patch filling in yet when coming inwards from the rounded tips.

But if helps if you can use as few surfaces as possible with extended areas that are trimmed rather than building every surface directly to some initial curve framework.

The other thing that's good about having a smaller number of surfaces is you can adjust the shape easier like with the steps above you can tweak the loft profile curves to control some subtle curving. When things are diced up into smaller pieces being filled in it becomes difficult to make a broad shape adjustment.
