Here is a cool new way to enhance your Instructables with detailed interactive 3D models created using Autodesk Fusion 360. I'll take you step by step through the process of publishing your Fusion 360 model on the Fusion 360 Gallery and embedding it in your Instructable. Just for fun, I'll be using a model I created retrospectively for the chicken coop I've just finished building in my back yard. Here is the embedded 3D model for you to play with - so you can decide whether its worth reading the rest of this Instructable.
(If you can't see the interactive 3D model above, its probably because you're not using a WebGL-enabled browser, or you're using the Instructables Mobile app).
