Nice one Matthew, good job, love the details!

Cheers

Thanks,
here is a rendered image, hope i will find the time to make some additional views ...
Must admit, the three lower Strings are not wound ;-)

Hey, I thought after doing the "test" guitar I could move on, and whilst I did get a better understanding in Moi from you guys, I am about to attempt this and struggling to see how I can create it. I've tried several methods in this thread, but I'm getting bad results. Mostly these "arch" shapes, along with the filleting of it.

I've included my shapes, along with a reference. It's seriously driving me crazy, as I personally have this guitar and want to recreate it in 3d.

Hi John, MoI's filleter is not really going to be able to handle those spots where you've got surfaces that are partially tangent to one another but then further along come to a crease.

For MoI's filleter to work those surfaces are going to need to meet at more of an angle to one another throughout their entire common edge.

Here is one of those spots that I'm talking about:



In this version, I have adjusted the top shape inward slightly to avoid that situation and make a more continuous crease along the shared edges between the surfaces:



This version can now be filleted throughout (using v2 beta Sep-21 version):



Result 3dm model is attached as 002_filleted_3dm.zip .


If you don't want to shrink the upper profile down at all, then that shape is just not going to be possible to fillet in MoI (at least not for some time to come anyway). You could try some other NURBS programs that have more advanced filleting than MoI such as SolidWorks, or you could also try switching to a more "low level" surfacing approach where you work on constructing surfaces more individually rather than using the solid modeling tools. That would be like building in some of the fillet surfaces by doing things like sweeping them, rather than using the solid modeling tools. But that tends to take a lot more time.

Once again Michael, I am amazed. With a few tweaks on the fillet sizes it would be exactly what I was trying to achieve.

What I don't understand though is how come it's possible to fillet the whole thing at once, but not by doing the different edges around the body? I need two different fillet widths, it doesnt seem like it's possible =\

Part of the problem with seperating your fillet's is say you do the top one first



Then how do you consider this next?



Here is an example I made by lofting just the bottom and top curves, then I could fillet the top and bottom seperate. It produced a kind of variable, but again changed your original shape a bit.

When you try to fillet in different passes, the initial fillet ends up creating some sharp corners, which creates difficult topology for the next fillet after that to try and deal with.

Burr has a good example and illustration of this above.

It tends to be ok to do multiple fillet passes if you have all smooth edges but sharp edges can create more difficult situations.


> I need two different fillet widths, it doesnt seem like it's possible =\

No, not currently in MoI, at least not easily. I do have it on my "todo" list to enable setting different batches of fillet radii within one single go of the Fillet command though.

That would probably be what you would need to solve this case.

Thanks, I guess it's back to polymodeling until the next thing I work on :P

Hi All...

I have problem with fillet.
Take a look at this, file attached :

Hi Anis,

The problem is got to do with the seams of the 5 wavy parts that are used for the Boolean being lined up with the seam of the cylinder.
Rotate those 5 wavy solids 90 deg before the Boolean operation and then you can Fillet.

Hello Danny,

Work fine, thanks...

Yeah the fillets being able to only approach but not cross over another edge is really the single biggest remaining general fillet problem.

If that part can get fixed up then I think the fillets will actually be in pretty darn good shape after that.

That looks really cool.

Awesome!

That looks excellent.
