The ability to model with solid bodies has long been desired in Fusion 360 but the wait is still on. I would like to introduce you to the next best thing, modeling with Surface Patches. Surface patches will work with all the basic modeling functions such as Extrude, Sweep, Revolve and Loft to create quick modeling features, bodies and components. Another great benefit of using surface patches is that they are simple to create and capture from other models and saved as components for use in multiple projects.
