For a complete illustrated workflow of what the add-in does and how to use it, please visit EkinsSolutions.com and/or watch the explanation video.

Install:

The installer downloaded from the App Store installs the add-in in the App Store location for Inventor add-ins.

Disable:

You can disable 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" checkbox at the bottom of the dialog causes the add-in to not be loaded in future sessions of Autodesk® Fusion 360™.

Uninstall:

Use the Windows "Add or Remove" programs app and look for "Nifty Dogbone" in the list and use the "Uninstall" option.

The attached file is an installer. I much prefer to use this than to have Autodesk repackage it because I can have my own EULA and the Autodesk Mac installer has had issues in the past. Although I'm not entirely confident mine will be better.

One known issue that I'll be addressing in an update, is that it will place dogbones in areas that are too small for a tool to fit within. You can currently work around this by using the "Edges" option to specifically select which edges to add the dogbone to.

My testing of the installer has been minimal because of my lack of access to multiple Macs.
