I need help with this neck.
I have finished all the Fender Stratocaster guitar totally made in MOI (I attach images).
But I can't make the actual neck shape.
I've seen all of Neil Smith's posts, Vegas Guitars Custom Shop, where I learned a lot about this, but Neil, made necks that are like the Fender Stratocaster.
It is difficult to explain, so I attach an image MOI_1.jpg, and also the 3dm file, only of the neck with all the curves that have served to do it.
The yellow A curve in the image should look like the blue C curve above.
And the references of the real neck are the B curves in blue of the 2 images included in the Neck.3dm project that I attach.
And the violet neck fillet to the left of A in yellow should look like the one indicated by the arrows on the green line.

Surely someone knows how to do it better than me.

Sorry if it is badly translated by Google.

Hi Booleano, I haven't had a chance to look into your case yet but I wanted to give you a link to a site that's focused on making guitars with MoI:
http://3dcncguitars.com/

You may be able to find some good information and tutorials there.

Hi Booleano, what about if instead of making the neck bottom a straight piece, if you instead made it a sweep that curved downwards at the end like this:



Then if it is trimmed by a side profile you'd get this kind of shape:





And also if the sides were extended up like this:



Then it could fill more space up and get trimmed down:





So you'd be getting this kind of larger trimmed surface instead of a patchwork of separate pieces:



Then the tricky part becomes adjusting the shape of the sweep so that it comes close to the end profile that you want since the end profile is formed by a trim rather than drawn in directly.

Does that seem like it's better or not?

Hi Michael:

Thanks for your answer and for the link that really did not solve anything for me because the purpose of this project is not to manufacture the guitar on CNC machines.
It is only to use the guitar, in a virtual background stage for a video, this guitar and many other modeled objects I made them in 3Dmax, but they are not well done, and I am making all the objects made in 3Dmax in MOI that everything is a lot easier and also helps me to learn to model with NURBS which is fascinating.
I attach some examples modeled in MOI and the link of a video of what I use them for.

In the image of the Steinway B-211 piano I have pending to solve the red seat of the padded stool, I will post this problem here when I solve this one.

Thank you very much for your great help.
I have a hard time understanding your explanations well because my English is not good enough, and I have to translate it with Google.
I would appreciate a lot if you upload your project to me, this would surely be definitive to understand it because it would have your curves.

Hi Booleano, sorry I didn't save off the file since it was just at a pretty rough "proof of concept" stage.

I'll rebuild it and post it a little later today.

But if I understand what you are asking about, it seems like you want a smoother and more drawn out curved shape along the bottom. So the idea is to build a single larger curved surface there shaped something like this:

Hi Booleano, see attached file. The shape of the sweep could be tweaked to make the area where it is cut out to come closer to your outline.
