Non Standard Threads

[Anonymous]

The threads contained within Fusion are quite comprehensive, however obviously can't cover all possibilites. I would like to see an option where non-standard threads can be correctly modelled from within Fusiion by selecting the thread specifications. For example I currently have a Schaublin Swiss thread which is 19.70 mm 45/5 butress thread at 1.667 mm pitch (no I'm not making this up!). Unremarkably it doesn't feature prominently in thread lists, however there are other examples where it would also be desirable to be able to modify standard threads as required.

 Those who are interested in this thread [excuse the pun] may also be interested in this thread/idea and may wish to vote accordingly http://forums.autodesk.com/t5/ideastation-request-a-feature-or/metric-thread-data/idc-p/6015864#M130...

There is significant crossover between the two idea; one sorts out the default metric data, as with all due respect it seems to be a bit of a mess. However the other allows custom threads to be generated. If the team at AD are looking at thread data within the various applications (F360 in this instance), it could be an opportunity to sort the whole lot out in one go.

I, too, would really like to see support for non-standard threads.   I love the simplicity of selecting threads from the drop down lists, but when your option isn't in there, I would love to be able to input some data and have it generate a custom thread.   I'm open to other solutions as long as it allows us to deviate from the default threads.

Personally, I'd really like to model some 6-64 threads.

A % thread engagment and pitch option would be nice to modify Normal thread size.  I need to fab 3/4" nut with a pitch 0.20" with a 50% engagement.

I've tried making a custom thread file for Acme 3/4-8 and 5/8-10 and I wind up with something like this for the 3/4-8:

The entire rest of that custom acme thread file does the same thing with all the threads.  Where did i go wrong?

Thank you for your idea, I have changed this to future consideration.  When we explore a more complete hole and thread tool this year I will add this to the list of ideas to review.

Cheers,

I came to this thread looking for custom thread functionality. I hope it gets implemented. I have a design that I can't complete without it.

Ditto the need for a custom thread tool. It doesn't exactly need to be as much as a "thread" tool as having the ability to sweep and profile you want.

Fusion can't be a solidworks replacement until simple things like this are implemented.

Hi,

If the comments above are accurate as far as the work-around goes for custom threads, then most of the programing work has already been done.

All that should be neccessary now is for the user interface to be modified to allow the user to actually set all the required non-standard thread details (diameter, pitch, thread shape, depth of thread, etc.).

I would have thought that it would be easy enough to check what happens if a design with a non-standard thread is opened on another computer. Having said that however, the non-standard thread details should be kept in the same file with the rest of the design.

Regards,

Brett

I wish I could upvote your comment Brett.  That's exactly the right point of view to take!  We're obviously very close to having this feature if they would just run the ball a little further!

Busted, unfortunately I can't help but feel that things have slowed down in terms of CAD/Modelling upgrades. Not that I'm suggesting things are easy with all this, but (from my perspective) nothing much seems to have happened in the past 12 months. Now, like a duck's feet, I'm sure lots has indeed been going on below the surface, so no disrespect to the team is intended and I'm just calling what I'm seeing. I've just gone through the Product Upgrades page for this year, and can't find anything significant in the modelling area beyond fixes or fixing up abysmal previous attempts like measuring and much needed fixes there.

Of the 3 suggestions I've made, all have received good support, the suggestion for a gear generator is now one of the most highly voted suggestions. All were either very simple or already half done anyway, yet NONE have progressed beyond "Future Consideration". The third suggestion was to simply change the metric thread data so standard threads were the default instead of idiotic, never seen, metric threads that started with the smallest thread pitch and progressed to the largest. "Standard" metric threads are the opposite, so largely all that is required is to just reverse the table. Come on guys, that's a 30 minute change in code, if that, yet here we are 6 months later and it's still "under consideration".

I appreciate there's a lot to do, and if suggestions don't get many votes it's a case of not being able to please everyone, but when ideas receive a large number of votes and still don't progress, it feels a little frustrating.

Where did my custom threads go ? Took me more than 2 days to make some custom threads and now they are gone. I think the software updates changed the paths or something happened. I can't find my custom threads in the Thread Type list.

Please help !

marius.chirita.uk :

Every time the software updates, the path changes.  So you have to go find your thread files in the old directory and move them to the new directory.  Really irritating...

I'm currently in the process of modelling/drawing up a adapter for two threads. One of the threads was included in the library, but the other is a very different beast. It would've been very helpful if I could use a "create custom thread" option in the create tab, and just select where it should go before providing the data for it.

If that specific threads configuration was saved to the file it would be easy for others to open the file later and see the thread data.

+1 for this feature (custom threads that can also use user paramaters like the rest of the software!) 

For what it's worth, I like many other hobbyists have made the move into Fusion, specifically for 3d printing and also open stack cnc machines. So standard threads and thread dimensions, or anything that forces the use of "standard" dimensions, feels a bit limiting, especially within the 3d printing community! 

All around, fusion has done a fantastic job bridging the gap for hobbyists..  So I was a bit surprised to see this limitation at first, as my clyinder was changing dimensions on me, specifically because there was no "standard" thread size that fit. But either way, keep up the great work, and hope to see various features like this go away from using standards organizations sizing as rigid limits. 

Thanks !

 I also vote for this feature, including multi-start threads. Vintage fountain pens commonly use 3-start threads for screw-on caps.

I am new to this forum and to F-360; there is a lot to like about this modeling tool, except it is missing one thing. I also desire a custom thread capability--but with an additional twist (sorry, couldn't resist): it needs to work on non-uniform cylindrical shapes, i.e., cylindrical shapes that are not of constant diameter. We could call these 'free-form threaded bodies."

I have looked at the coil capability in the Create drop down; what I need is a coil form with slots in it, not the coil itself. The need is to 3D print a body that has slots (threads) in it, into which I can wind wire that coils upward. The diameter of the cylinder can vary gradually as one moves up or down the body, but the coiled wire stays in the slots which are of uniform separation as threads are. I also need control over the slot depth, shape, and turn-to-turn separation.

I appreciate all the comments above in this forum topic, and I sense that those posting are kindred spirits. It was surprising to me that a package as powerful as F-360 does not have this feature already.

It's good to join you folks in the forum.

Was just about to post the same, think everyone has summed it up. Adding my vote for Custom Threads In Fusion 360!

Another reason custom threads are absolutely needed: 3D printing.

The standard thread profiles are all unsuitable because they have 30 degree overhang angles. A buttress thread or a thread profile that has 45 degree angles is needed for 3D printed threads.

Unfortunately, the Coil command is both broken (see multiple other threads regarding coil primitives and the problems they have with the origin point) and it will only generate equilateral triangle profiles, which once again have 30 degree overhangs. Using a custom swept profile isn't viable as it would require manually creating the thread coil, which doesn't work because it will only create a solid and not a profile.

As others have said, standard threads are great but there are many, many times where custom ones are needed. Threads in Fusion only work if you stick to standards. Ironically, holes are the exact opposite - how in the world are standard hole sizes and clearances (and dimensioning while placing the hole without creating a single-purpose sketch) not a feature yet?

It's been over two years since this thread was opened, which gives me just about no hope of ever seeing a solution. Just another day in Fusion.

Thread Tool Settings Vs McMaster Carr Specifications.

They don't match up so I don't know what Thread Tool settings to use for that nice Vented Hex Screw I selected. See it at www.mcmaster.com/#90220A130. Please help 🙂 

Thank you

Just adding my 2c worth - I produce a LOT of drawings (in other packages) for optical systems (bespoke telescope element holders) that require non-standard pitch threads. Often these imported systems were built in places that seem to eschew any thread standard that we can readily identify.

Fusion 360's lack of such a basic feature means that it is effectively barred from being useful in this particular field.

Making matters worse, for us, we also need make our own threads to fully utilise some of the capabilities of the new novel materials we are developing.

I hope you can see fit to adding this capability soon.
