Every time someone asked for a custom thread (or a standard that isn't included with F360) here in the forum or I needed one myself I would think about writing some kind of utility to make the whole process easier, and each time I would mull over whether it would be worth investing the time for such an occasional requirement.
Well, some months ago I bit the bullet and decided I'd finally write something. It's taken a few months on and off and although I really wrote it for my own use I thought I might as well share it.
It can take an existing F360 thread file and convert it to CSV (which can be edited in your favourite spreadsheet program) and it will also open a CSV file (of the correct format) and allow you to generate a new thread file. It has the ability to adjust the Major, Pitch, and Minor diameters by a given amount to compensate for 3D printing (an alternative to adding an offset to the faces of the thread) or for creating in-between sizes (such as a TR21x4 - used on Sodastream CO2 cylinder). I've written a basic 'Rough Guide' that's included with the app but hopefully most of it will be obvious enough.
It also includes a form for manually entering thread data and a calculator for non-standard metric threads. This took a lot of time studying the ISO standard to get the code right for this so was very relieved to get this part working! Maybe one day, when I feel like diving in again I might take a look at adding other thread standards. I have included some sample thread files and their corresponding CSV files that I've either generated myself or collected from elsewhere. I can't guarantee the data is 100% correct so I'd recommend checking any you do use against other sources.
Here's a screenshot of the main application window.
Anyway, I hope some of you find it useful. You can download a ZIP file which includes the application, the rough guide and the sample files here. Hopefully you won't have too many questions.
Edit: I was reminded by @HughesTooling to mention the ThreadKeeper program for syncing custom thread files. I highly recommend it for making life much easier!
If this answers your question please mark the thread as solved as it can help others find solutions in the future.

I've created a Windows application for creating custom thread files for Fusion. You can find out about it here. Hope you find it useful.
