IMPORTANT: The formulas I used for the fret spacing (from fret 2-24) may cause performance issues. I have released an updated video (kzread.info/dash/bejne/dIGplaePZ5zLkpM.html) with a better formula to solve this and added compound radius and constant edge height.

and i assume a compound radius would just be two values, a curve at either end each using a plane and then loft between them?

Yeah, I had to subscribe to the Patreon after watching this one. Just didn't feel right getting content of this quality for free. Thank you so much, Austin!

This was so interesting. I learned alot from this

Very useful. thank you so much

Great work thanks.

As usual brilliant stuff Austin, Thank you for putting all the effort into doing these videos! Mike

Austin, you videos are pure gold, amazing! Thanks for sharing! Rock on!

Yet another outstanding video, Austin. Many thanks!!

Amazing job with this tutorial! I tried this the “long way” by doing a formula for each fret. Nice to see a less parameter intense way to do this

Thank you very much!!! You are the best!!!

You rock! Thank you for this...I was watching as a someday-maybe thing to do. Half way through, I started over and created the template along with you. This is such a time saver!

Thank you. Your a beast

This is the most informational tutorial for fusion that I have ever seen. I've been struggling with the fretboard and now it makes perfect sense. Thank you!

Thank you so much for all the content. There isn’t anyone else on KZread that does provides the same level of detail while still keeping it accessible for beginner CAD users. Would you consider doing a video for arch top/les paul style bodies? Including in that would be angled neck pockets to compensate for tune-o-matic style bridges. Thanks!

Apparently works very well if you have 8th or 9th fret virtical. But its all personal prefs and feel. Great work and very useful.

Fantastic tutorial, thanks so much Austin. I tried both methods, formula driven or multiplier and while the multiplier is very close, it's not 100% perfect here using mm as units the 12th fret (using very high zoom) wasn't perfectly in the middle but the formula driven is perfect and such a great tool thanks

Man, I just made something similar but for the whole neck. It is working on the sketch but not on a model. It always brakes on a neck to headstock transition. It's still a big time saver sins I just need to patch the surfaces. I must say you did it a lot cleaner and easier than me. I learned a lot again. Thanks Austin!🤘

Really interesting method! I just discovered your channel and your tips are really helpful! About two years ago I began to work on an add-on for fusion 360 to generate a full neck with frets and everything, I got it working, but it was really slow due to all the API calls and everything, it was a real pain to update any parameters... Since then, I moved on to a way faster standalone program that can generate a complete step file to be imported into any 3D program, I have a few things to tweak before releasing it, and I would especially love to make it work in a browser. If you want to have a look, I would be glad to send you an early version!

Awesome! Others have also mentioned compound radius. What about parameterizing the number of frets. Another might be the angle of the “theoretical “ bridge to the centerline. At that point a plug-in might be the easier route.

I can't subscribe more than once but I would if I could. Well done

Speaking on time 0:0:0 - 0:30:00, this seems most beneficial when need a multi scale FB. Maybe I’m missing something cause I’ve just been using either your parametric FB or fret find to import the frets. In any case, thank you very much for all your teachings. Top notch.

This is amazing Austin, really enjoying this series. I have made a slight adjustment to avoid compounded length by referencing all frets to the nut. I've put in some time to create a parameter for each fret but used a modified formula where I adjusted the (2^(1/12)) to be to the power of the fret position/number. In other words for fret 3 I used the formula LowE_Scale_Length - ( LowE_Scale_Length / ( ( Fret_Factor ^ 3 ) ) ) and for fret 2 I used LowE_Scale_Length - ( LowE_Scale_Length / ( ( Fret_Factor ^ 2) ) ). The Fret_Factor is (2^(1/12))

Hi, Thank you so much for this, it was a great help and being a complete beginner with Fusion, was still able to follow because of how well you went through explaining everything in detail. Quick question, is there a way to set a parameter and edit the number of frets on the board or would that just have to be a separate drawing?

Brilliant tool and tutorial. Very well done and thank you. This will save a ton of time. WIth other similar designs I do however have challenges selecting faces for manufacturing of the fret slots. In fusion 360, for Manufacturing of the actual fret slots, did you use a Trace command and if so what surface or line did you select?. Fusion does not appear to allow selecting this as pocket. Or at least I have not been able do so in manufacturing. Any guidance based on your experience to date would help. Current I use trace but this has issues with fret at the nut by 1/2 the thickness of my tool (.020")

I already had a parametric fretboard and I wanted to remake it to be able to include multiscales. My method was not far away from your but I got a few techniques from your great video. Thanks a lot for sharing. However you don't use a compound radius ? My technique for the compound radius was to sketch the radius on the nut end face, give it a parametric value (say 12"), then sketch another on an offset plane at the heel level with a second parametric value (say 20") And then loft from one to the other. I haven't tried it on a multiscale but it worked great on a single scale.

Great videos, learning alot from you! Question though, why wouldn't you want all of the scale lengths to be angular? Scale length and fret spacing should be measured at the string, which is angular, not the horizontal projection. We are talking a difference in a couple hundredths of an inch on scale length so it probably doesn't matter, just curious if there is a significant modeling difference or some reason causing you to prefer the horizontal

Great, easy-to-follow video!!!!! Is it possible to do parametric fretboard with compound radius? This would give a little more flexibility in the parametric design.

Great video. When I combine and join bodies sometimes the lines remain on the combined body , is there a method to make it appear seamless?

How you determend the Heel width dimension? If its the bridge E-E dimension, what about string/nut overhang , I'm curious.

huge

Thank you so much for yet another totally AWESOME video. This will be life changing in terms of removing the tedium of drawing fretboards. However, most fretboards really should have a conical radius (compound radius) rather than cylindrical. How would I go about adding the ability to make the radius at the last fret correct for any given bridge radius. For example, if the radius at the nut is 10" and the bridge radius is 14" the 24" fret will be somewhere in between these two values making a cone.

I found the best way to do this is to create a lofted surface between between 2 sketches defining the camber at both ends of the fingerboard. This could be incorporated into Austin's design with some additional work. It would have to extend to the longest side of the fingerboard on multiscale necks

@glasgowguitarist3636

2 жыл бұрын

@@mattsta1964 yes, I thought a loft would be the way to do it. I’ll need to do quite a bit of trial and error (probably more error than anything else 😬) to integrate it into Austin’s model though.

Can I make a feature suggestion? I think many people will know what nut width they want but no idea what the heel width would be especially if an odd scale length or extra frets, etc... But, they will know the bridge width E-to-E. Maybe have the option to choose either heel width or bridge and it can calculate neck width from that? Since with the scale length it should know where the bridge is. May need to add space of strings from edge of the neck. Just an idea.

@austinshaner

Жыл бұрын

Sorry for the delay. And yes, I want to do this on future versions. It's a bit of a catch 22 as sometimes the dimensions listed include heel width, but If you're doing a scratch build then you'll derive it from your bridge selection. Future versions of this model will likely use string spacing as the driving dimensions which also opens the door for variable number of strings.

As usual, that's great! My Mathematical past just tells me to put 1 / ( 2 ^ ( 1 / 12 ) ) for Fret Multiplier. I always prefer to have "round" value or expression... :p Just my "Sheldon Cooper" who's speaking here. :p

Great video, I learned tons. Question, does the multiplier change for every scale length? In the video you show how you calculated it, but it should change for each scale length correct? If so, how are you calculating it dynamically when you change the scale length parameters for a new board? And wouldn't that mean you would need 2 multipliers for fanned fret designs (lower and higher)?

@austinshaner

You would think so, but that is not the case because all scale lengths still follow the same set of rules (12th root of 2). You can validate this by dividing the second fret by the first fret from 2 different scale lengths and they still arrive at the same number (multiplier), because the ratio is the same, even if the value is different. Hope that makes sense.

I know that you recommend using the updated template, but since im learning how to use the software...is there a way to make the fretboard radius a parametric function?

Austin I wonder if you could help please? I thought I had followed you note for note on this until I got to the dimension for the heel width and although I dragged it out parallel when I left clicked to put in heel dimension I got a window opened saying over constrained and asking to create a driven dimension instead?? What did I do wrong?? I check my screen against yours and I seem to have the same constraints i.e centreline/origin/fretboard end and last fret parallel constraints and nut end and bridge centre constraints. Any ideas where I might be going wrong? Hope you can help Thanks

Used the multiplier method. Up to fret 12 all was good and lined up perfectly, however after fret 12 fusing began to slow down and by fret 20 almost at a standstill. Any ideas why?

I am following video on parametric modeling a fretboard, for some reason when I apply user parameters to sketch the fretboard sketch twists and will not allow me to draw frets on fixed fretboard outline. Any idea what is going wrong???

This is such a great idea. Thanks for sharing. Only problem I have is one of performance. As i create more frets the longer it takes to dimension them, I'm on fret 21 at the moment and it's taking about 5 minutes to create each one due to the MacBook hanging...I'm wondering if this is just due to the amount of calculation being performed? When I adjust other parameters on the fretboard it is now also taking 5 minutes to update. Is this something you came across? I'm using a 2015 MacBook Pro with i7 and 16gb ram. Thanks

Cannot extend extrusion to object. The extrusion profile falls outside the boundary of the selected body. Select a face or plane instead, or adjust the profile so that it falls inside the boundary of the selected body. Any ideas why this could be happening?

Hey Austin, I was just adjusting the fretboard to make it consistent with the updated fret position fx and noticed that my 12th fret does not actually pass through the origin. It looks like it does until I zoomed in and found it was just off. I went back to my first version and found the same problem. The midpoint horizontal line is centered on the origin so I'm at a bit of a loss. I'd post a pic, but I don't think I can do that in the comments.

Hey Larsdan, this is likely more a display issue than a calculation issue. If you go into your fusion settings you can change the amount of decimal places it shows in your sketches, which will bring that line much closer. If you zoom really far in you are looking at less than .001" scale so it may look off but it's just Fusion rounding up or down to save your pc performance.

According to the Fret Multiplier... if you use the metric system you get 0,9438738283661669 as value, which is even more accurate... this gives you a deviation of only 2 microns when you measure from mid point of thread 12 to your origin... FYI: I used the "18 Rule" for calculation for accuracy 17.817 is used....

Use this new surface to click to and check the little box in the extrude setting that allows you to go through the objects below. You will need to compensate the “tang depth” for the extra height of the surface you made, in this case it was .02 added.

The error message reads: 'Adding this dimension will over-constrain the sketch. Choose OK to create a Driven Dimension.' I can not add anymore lines nor any more equations once I get that message. I have scrapped the sketch several times, but I get the same error. I deleted the file and created a completely new project, but ended up with the same issue. I decided to go the other route you mentioned in the video and added all the fret dimensions to the user parameters page, but that puts such a load on the file that it takes 15-20 minutes to complete any operations. I was able to add all the frets and get them dimensioned, but I have yet to complete the file because it now takes sooooo long to complete any operation when I add anything new to the file!
