Start by storing thread definitions inside ThreadKeeper's threads directory. Open the directory by clicking TOOLS -> THREADKEEPER -> Open ThreadKeeper directory.

If you already have thread definitions added to Fusion 360 that you want to keep, open the Fusion 360 threads directory and copy them to ThreadKeeper's threads directory.

Note that the files in ThreadKeeper's directory can be stored in a nested fashion (i.e. inside multiple directories). Note, however, that the file structure will be flattened when copied to the Fusion 360 threads directory.

ThreadKeeper will sync the files every time Fusion 360 starts

To copy the files to Fusion 360 directly, click Force sync.

To change which directory where threads are stored within ThreadKeeper, click Change ThreadKeeper directory....

The add-in can be temporarily disabled using the Scripts and Add-ins dialog. Press Shift+S in Fusion 360 and go to the Add-Ins tab.

How do I get threads?

This add-in does not contain any thread definitions.

You can either create custom definitions yourself. See Creating custom threads and thread standards in Fusion 360.

You can also download definitions that others have made.

Examples:

• Fusion-360-FDM-threads
• CustomThreads

Install:

1. Download the installer from the Autodesk App Store.
2. Right-click on the "Downloads" folder and select "Open in Finder".
3. Right-click on the "ThreadKeeper_macos.pkg" -> "Open With" -> "Installer". 

Uninstall:

You can unload the add-in without uninstalling it by clicking the "Stop" button when the add-in is selected in the list box on the "Add-Ins" tab of the "Scripts and Add-Ins" dialog.

Unchecking "Run on Startup" causes the add-in not to be loaded in future sessions of Fusion 360.
