ThreadKeeper is an Autodesk® Fusion 360® add-in that restores custom thread definitions every time they are removed (i.e. when Fusion 360 is updated).


Thread definitions to restore are put in the Threads directory of ThreadKeeper.


Every time Fusion 360 starts, ThreadKeeper checks if thread definition files are missing. In that case, the files are restored.


This add-in is free, but if you like it, you can buy me a coffee (Ko-fi link).

    To install I had to copy the .msi file to "C:\Users\username\AppData\Roaming\Autodesk\Autodesk Fusion 360\API\Scripts" to run, If it's intencional maybe you should add it on "how to intall". Thanks, I hope it works.

    Hopefully Autodesk will release an update soon. If the "Force Sync" menu item works, there is a big chance that the add-in works well during a Fusion update as well. Regarding the installation instructions, they are provided by Autodesk. The .msi as well. I did try it when the add-in was released and did not see the problems you are seeing. I will keep a look out for any more reports of installation problems. (And, just in case you unpacked the msi manually: API\Addins is the correct directory for add-ins. (In the case of DirectName, having it in Scripts should not give any loss of functionality, as far as I can tell.))
