Here is a quick description of the useful workflow:

In a large assembly you may have some hidden bodies that are hard to find in the tree that you want to show.

Run the addin

You will see the new icon/Dropdown menu in the lower navigation bar on your screen

Select: Show Hidden Bodies

Now all the previously hidden bodies will be displayed.

Hide the body you wanted to show originally

Select: Show Hidden Bodies

You now have the previous state with the desired bodies shown

Install:

The installer that ran when you downloaded this app/plug-in from Autodesk App Store has already installed the app/plug-in.

OR, simply double-click the PKG to install the app.

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 Autodesk® Fusion 360™.

- Navigate to/ApplicationsPlugins and select the app you want to uninstall

- Either drag the application icon to the Trash, or right-click and select “Move to Trash”

- Right-click on the Trash can and select “Empty Trash”

- If you prefer keystrokes, you can also just select the app bundle and then hit Command+Delete to move the app to Trash, then empty the Trash and the app will be removed.
