[@AgustinSaldias]

I've never thought of using a coil as a temporary guide, that is a great tip! Of course we all could use normal threads but creating specifically 3d printable ones with custom shapes is a game changer, thanks for the video explanation!

[@ydoucare55]

This is a good method for 3d printing to be able to control the overhang angle so you can get a smooth interface between parts. Nice job!

[@eduardo33]

Watching several times in low speed, Tks!!

[@Phenex125]

Nice approach. I like the pacing very much, great explanations how and why things where decided. Very much prefered over the drawn out tutorial one usually find in this topic!

[@getprototyping]

Thanks for the nice feedback!

[@Djeez2]

Very smart to sweep around a coil edge! Thanks for the tip.

[@jendafojtik]

For anyone wondering why the combine is not working, what helped for me: slightly lower the distance from 0.3 to 0.25 between the threads and also increase the overlap of the profiles of the threads from 0.05 to 0.1. For me, the problem was that Fusion didn't detect the overlap as significant and this worked like a charm so sharing with the rest!

[@zm7160]

If you look at injection molded threaded items: like bottle caps, pill bottles, etc; you'll notice most don't have the thread start near the top of the body until it reaches full thickness. Actually there is usually a completely bare buffer region near the top of the body and corresponding base of the cap. It's not a great idea to have the thin profile thread on the lip of the body where it has no "meat" to it and will easily get warped or damaged - especially if you're gonna 3D print it.

[@MrSchnoufy]

An interesting approach to the threading mechanism for 3D printing. 👌 Thanks for the explanation. 😉 I still had to watch the video in slow speed to understand everything properly. 😉 I've learned a few more things thanks to you. 👍

[@CraigHollabaugh]

Excellent approach. Thanks.

[@MttUrs]

That's so smart I'm angry and amazed at the same time

[@paulushdk]

thats a neat tutorial. Thank you very much!

[@evrac1]

Great pace and great workflow. I've done lots of custom threads and this certainly reduces the number of steps. Thanks!

[@getprototyping]

Thanks, really glad to hear this was helpful!

[@Flachknipser]

Thanks for the video very much, maybe a little too fast, but the path shown is great. Hope for even more like that.

[@getprototyping]

Thanks for the feedback and encouragement! Will certainly do more.

[@MrFamousguy13]

@@getprototyping Speed is good for retention. Like you said you can pause the video. Long videos that are not straight to the point SUCK ASS. Short to the point fast paced videos are best no wasting time. Thanks for the speed

[@invenioengineer]

Hi and thanks for your video, its very helpful to see the process. I am having a bit of trouble using the coil feature. The location of my coil is not at the origin and when I go to sketch the circle for the coil I dont seem to be able to locate it at the centre of a boss that is ofset from the origin. Any ideas how to do this?

[@paramtrx9558]

Nice Thx!

[@robinbiskupic2639]

A good alternative to modelling both thread profiles for the inner and outer thread is to simple subtract the thread from one side to the other and use the offset face tool to make clearance

[@getprototyping]

Can be certainly done like that. Excellent way to make the process even more efficient. 👌

[@chybanie716]

Yes and no. Depends on the shape of the thread profile. If you would do this with the thread profile containing curved surface like the one in the multistart version of this video then it wouldn't work. Not trying to be mean, I value a mind that analyses what it sees, just brainstorming here ;)

[@petrowi]

Very cool! Can you pls show how you animated the thread?

[@getprototyping]

Thanks! Will make one about joints and animating soon.

[@alexgonzalezpk]

Nice video!

[@getprototyping]

Thanks!

[@JamesRothschild]

Wonderful, thank you! I will transpose your workflow into my 3D software of choice (Cinema4D) √ :-)

[@bwilliams1815]

I love Fusion but this is much harder than it really needs to be. Fusion team, please add user defined section in the coil generator.

[@grepmonkey]

Excellent tutorial. Would you consider showing how you would apply your preferred technique to create a threaded connection between two parts that are not created from a revolution? Such as adding a stool leg to multiple locations on the stool seat? I have done this with the thread library but love the idea of creating better, 3d printable threads.

[@JuanAdam12]

Couldn’t you (attempt to) follow his example once and then do a circular pattern of the finished bodies where the legs of the stool will be?

[@getprototyping]

Thanks! You could duplicate the thread body after creating it once, either using a pattern or by copy & move. You'd just have to do it before joining the thread to the main body/bodies.

[@thomasmistretta3309]

Great tutorial but make make sure you drink a pot full of coffee to keep up

[@jonathanmelancon3021]

Perfect speed. It's not a video on how to use fusion.

[@marinamarinx7655]

Please show the thread of the first Video pic on the right side what combine two theads

[@getprototyping]

It is called a Buttress thread. The top chamfer makes it look a little more special than it is in the crossection view.

[@MAXimator70]

Great workflow but a little bit too fast. Nonetheless i subbed! ❤

[@D4RKFiB3R]

Man, what are you doing at 2:02? I can't keep up :(

[@lazyman1011]

Nice! Abo out!

[@Cyberneticduck]

Creo has much better functionality imo in regards to coil, there should be an option to have custom profile in coil menu

[@getprototyping]

Agreed, Creo‘s Helical Sweep offers more functionality. For the outline profile there is a straightforward workaround in Fusion, variable pitch afaik poses a problem in Fusion.

[@Cyberneticduck]

@@getprototyping I wonder if a plugin can be designed for such purpose

[@getprototyping]

Maybe I will look into it at some point, but probably not within the next few weeks.

[@broderp]

Please slow down, maybe doble the video lenghth...please.

[@sierraecho884]

Why to do custom threads ? I am a CATIA user and I don´t have a library of threads so I have to design them every time from scrach ...again ..and AGAIN I wish I could simply use some coarse pipe threads from a library instead.

[@getprototyping]

You can of course use a library for standard threads. You can also use your own templates and even addins. I will probably make a video about these things at some point.

[@sdfgsdfg3789]

Austrian?

[@FrodeBergetonNilsen]

As a designer, why would I want to do this? I fail to see the real benefits.

[@getprototyping]

There are a number of scenarios where standardized threads do not work well. Most commonly, standard clearances are generally unsuitable for 3d printed solutions. I generally like to have full control over the thread design when I print both components. Also, there is an virtually infinite number of uncommon (or even non-standardized) threads out there you might want to interface to (jars, bottles, fine threads, even sawtooth profiles, buttress, tapered threads, ...).

[@drydiver]

Your videos are intersting, but too fast! It's impossible learn anything this way!

[@getprototyping]

Thanks for the feedback!

[@JuanAdam12]

Totally agree and have commented about this in other videos. Would LOVE to really understand how to make custom threads but this speed ain’t the way to do it.

[@horrorhotel1999]

Disagreed. Watching on 2x speed and having no problem understanding what's going on. Just pause the video when following along on your own computer. I don't really know how you could make this any more detailed without cramming in knowledge irrelevant to the core of this video.

[@JuanAdam12]

@@horrorhotel1999 really. 2X speed. Got it.

[@D4RKFiB3R]

@@horrorhotel1999 2x speed! Look at this super human over here 🤣 Perhaps consider that viewers of this video may have vastly different experiance levels using this software, or any kind of CAD software at all, yet still wish to learn this teqtechnique. It would be entirely possible to cater to such users without turning the video into a fusion 101 basic lesson. If it was just a little slower, but far more importantly, if the names of all tools/operations were mentioned, it would help novice users who are trying to follow along a great amount. Rewinding multiple times doesn't help much if the mouse is still flying all over the place at 1000MPH, and you are never told verbally what is actually happening. Personally I am very confused about what is taking place at 2:02. I think mistakes in tool selection are being made and corrected? But without an audio description of what is "supposed" to be happening, I am finding it very difficult to understand. Please, try to be less condescending to those less knowledgeable than yourself. We all have to start somewhere, right? (even though this video may not be the best place for that).

[@jasonjordan9598]

Dude, way to fast on the initial sketch even slowed down.

[@getprototyping]

Sorry if this frustrates you. I decided to make it short focus on essentials of the process rather than every single step.
