Arbitrary thread pitch/diameter combinations

I did a quick search for "arbitrary thread" and came up with nothing, but I am really curious about whether Fusion is going to contain the ability soon to easily create arbitrary combinations of thread pitch and diameters. This is a very common design feature in many types of mechanical "stuff", where the lathe needs to produce a thread of, for instance 1.700 diameter x 20 TPI, or a 10.5mm x 0.7 pitch thread.

 

I understand that there is a developed 3rd-party(?) facility for this, and/or some method for doing a temporary modification of some XML(?) file to enable a "special" configuration, which then can't be saved as a permanent library item (I think), but it would obviously be far easier if the thread could just be constructed in the native software functionality. Is there any hope for this in the near future?

Its already there. There is an editable file that you can add or delete or modify on your computer.  Sorry don't know the the name offhand but its pretty straightforward once you find it.

Thanks for the responses; this seems to be the state of things the last time I looked into the subject. The 3rd-party content "Custom Screw Creator" from Fabian Schurig has some issues apparently; most of the reviews mention being unable to make it run. I downloaded it myself some time back, and experienced that, and it doesn't appear to have gotten over that hump yet.

The editing of the file(s) in Fusion 360 is "straightforward" by following the directions well, but you have to restart the software after the editing process, which is a time sink in itself, and there is always the risk of making a typo and losing some standard thread designations from the look-up table, as well as then needing to re-perform the file editing. 

 

There is absolutely a way to make custom threads, but it is over-complicated IMO, and quite cumbersome. I am not familiar enough with how the actual code has to function in the context, but it just doesn't seem like it should be a big problem to create a thread construction function that has drop-downs for type of thread, then data entry for any pitch, any diameter, and how many starts. It may be that a look-up table for standardized sizes is way faster to get a result, and that could still be there in the background, but being able to generate the thread from the thread command would be way better than having to go modify a file, re-start the software, and hope that there is no error in your editing. And then do it again for the next one. OK, whining session over.
