Fillet/Rounded corners issue.

[TOwens777]

I am working on a guitar body.  It's a solid model with no t-splines.  I'm tryting to round the corners off (see attached.)

The Fillet function does not work stating the fillet cannot be created at the requested size (which happens to be any size.)

Is there another method I can use to round off these corners?

Thanks,

Tim

I think you're thinking of Construction planes, under the Construct button of the toolbar.  Trippy used the Sculpt Create > Plane and reduced the number of faces to 1 (default is 4), which is the same result as using the Face tool.

Oh...  Didn't know that.  Thanks!!!

I finally got to give you guys some kudos. This conversation is awesome and a great example of good community. Nice and professional too. It's appreciated.

I've been doing some workflow testing on the next release. I picked what I thought would be an easier guitar, my ES-335, and if you know these pretty babies you know they have a slight dome to the top and bottom faces which I will solve using Edit Face if at all possible (once I get there). Modeling guitars is an art, I'm learning. 

I just finished the neck/headstock down to 12th fret. Philtone is my brand, for better or worse. 🙂

Thanks guys, I'm avidly following this conversation too!

PS: I found some excellent Gibson spec drawings with a little google searching... 😉

Phil, that is amazing!  Makes me want to hang it up.  You guys are light years ahead of me...

[TrippyLighting]

Dont! We did not get there in one day either 😉

Yeah, rendering assemblies like that looks awesome, but my main view is to keep your eye on the ball/end goal -- tangible objects and guitars, and maybe even production or whatever you want to do at some point 😉  I know you're light years ahead of me in being able to design an awesome guitar, and hope you'll even let me use a similar design soon for educational content of how to go from idea to model to machined object in hand (of just the body probably).  All this fancy CAD, CAM and CNC stuff (and kudos by the way on already starting to have your hands in all three of these three lettered juggernauts) is and always will be just tools, abeit very powerful tools, for the human creative mind.   

What you learn over time, even a little at a time, will be useful for you for as long as you can design and make things.

I looked at the images and actually think I would only model this with surfaces and not TS.

I did two guitars back some time and it is possible but requries a lot of experience skill and manual labor time.

I find it easier to block out the different shapes as separate objects and then use the solid combine command to add or remove

material.

In the last step then all edges will be rounded in logical orders such as round first all vertical lines and then all horizontal lines.

For example try this with a cube:

round all edges at once

compared to

round all verticals

then all horizontal edges

Also a good idea is to ignore filleting or blending transitions in sketch as I feel that makes things more complicated.

Just work with hard edge models because Fusion is pretty good at rounding later the solid edges instead of the sketch edges.

This also makes adjusting the sketch later easier.

Hi @cekuhnen,

This is thread would tremendously benefit from a screencast, perhaps even an attached model that shows how to do what you've described.

Jesse, that's the plan!  I have brand new CNC waiting for me to finish this model.  I'm wanting to start doing my guitars full time. It's just not practical to carve them by hand (for me at least); way too time consuming.  I think they will sell well.  I have some unique ideas that I think have a market.  I'm ok with someone using my design for education purposes but I really don't want anyone copying them for production.  I need to make some money from them first.

Here's where I am now.  The solid body I have now was a pain in that I had to painstakenly get all the measurments right for the hardware.  Great guitars are all about precision and that's one reason the CNC aspect appealed to me so much.   I am able to follow you guys in creating a t-spline body with the curves but I really don't want to have to go back and redo all the hardware routes, cavities, neck joint, etc.  So.... what I'm trying to do is (I think someone suggested this) only the outline with the cutaways.  I would like to keep the center body from the solid model and combine it with the t-spline outer portion.  I did a nice t-spline body but it didn't fit well.  I made the mistake of using the sketch body as a template.   I'm redoing it now using the solid body instead.  I think this one will fit much better.

Thank you guys so much!!!  I really appreaciate all the help!  Hopfully I can have the CNC cranking out a few of these puppies by fall.

The link returns a 505 error.  Can you try reposting please.

odd works on my side

That one works.  Thanks!

[TOwens777]

The video was very helpful!  Thanks for posting!

[cekuhnen]

you are welcome I hope it provided some insights

[TOwens777]

Ok, this was hard but I accepted Trippy's suggestion to do this design as a sculpt as the solution.  Everyone was SUPER helpful with this. I think my original sketch had too many non-tangent areas for the fillet to work properly.  Either way I learned a ton!!

I'm going to keep this thread going until I finish this project so to have all the information in one place for others working on similar guitar projects.  It would be nice if an admin could rename the thread to something like guitar design issue or whatnot.

Here is where I am now.  I have completed sculpting the ouline for with the rounded corners and cut aways (see attached.)  I did this as one piece for symmetery reasons.

My original solid model design has all my hardware routes.  These are very precise and I don't want to have to recreate them.  So... I want to create an outlne that will encompass the old cutaways and edges of the original design; extrude that as a cutting too and remove them leaving only the center portion of the guitar containing the hardware routes.

Then I need to split my new sculpt into two seperate pieces.  The reason for this is that the top and back of the guitar must be two pieces and routed on both sides then glued together.

I see there is an option to split a body by several methods.  I'm thiinking the best way would be to use a plane.  Would this be the best method?  Would I use a construction plane?

THANKS!!!!

For someone that has stated that he has no prior 3D experience you have made impressive progress, so a big KUDOS for that.

It is also a testament to the efforts of the Autodesk team that makes software that does complex things so accessible and intuitive.

[cekuhnen]

Pretty fantastic result! You can also use the curvature graph to better judge the surfaces and topology quality with T-Splines!

[TrippyLighting]

Another thing that is probably obvious but did not occur to me. Thanks for the info!

[cekuhnen]

Yeah if you work with Alias and then look into Fusion Fusion is really more accessible.

It would be pretty fantastic if at one point the curbature graph with TS also could work with G2 and not just G1 so the result would be smoother to evaluate.
