You find Windings in your Tools/Add-Ins

Press 'Run' and go back to the Solid Menu.
You find Windings on the bottom of the Create-Dropdown of the SOLID Menue:

If you select 'calculate windings' you see the end result previewed.

But this slows down the program. So leave this turned off until your windings settings fit. Then calculate windings to make the wire-shape settings and if all settings are done press ok. It will need a minute to calculate complex windings.

Install:
The installer that ran when you downloaded this app/plug-in from Autodesk App Store will start installing the app/plug-in. Or, simply double-click the downloaded installer to install the app/plugin.

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™.
To uninstall this plug-in, exit the Autodesk product if you are currently running it, simply rerun the installer, and select the "Uninstall" button.
Or, you can uninstall it from 'Control Panel/Programs and Features' (Windows 7/8.1/10), just as you would uninstall any other application from your system.
