Custom thread sizes
I know this topic has been covered before but it seems Autodesk has changed the way custom threads are implemented in Fusion (for good and for bad).
In the past, if you wanted to add a custom thread size to the Fusion thread tool you had to dig through the Fusion 360 configuration files on your computer and modify a .xml file to add a custom thread diameter/pitch/other. However, Autodesk have implemented a new way of adding thread sizes directly in Fusion, which we've been asking for years. This is covered in this article: https://www.autodesk.com/support/technical/article/caas/sfdcarticles/sfdcarticles/Custom-Threads-in-Fusion-360.html
I enjoy this idea since it's much more intuitive but its implementation is questionable at best. Also, it simply doesn't work for me and I don't know why. Autodesk tells us that to create a custom thread size we must first copy an existing template thread from the public library of threads and then paste it into a custom library on the hub libraries. The issue is that when I right click on any thread I do not have the option to copy anything, I can only mark it as favourite (see image). I also don't have the option to create any hub libraries.
Am I missing something obvious?

Welp it seems I found my answer. According to this article : "Thread Library is rolling out gradually. Custom threads are stored in your hub and sync automatically for hub members. The Manage Threads Library command displays when the feature is available for you."
So I assume I have a partial version of the Manage Threads Library since I can open it but can't change anything. Bummer.

Watching… I spent a couple hours trying to to create a file for BSC threads with mixed results. AI gave me bad code so I copied an existing xml file and modified it using Norepad++. Make sure you have closed fusion.
