Fusion 360 Ultimate - Problem with Boss Extrussion

[quaverf]

Encountering a problem extruding a boss from a simple 2D sketch.  My desire is to extrude the boss from the surface of an existing component and have the boss be joined to the existing component.  I have tried to do this simple procedure several ways. Saved and closed the model, re-opened but no change.  Closed Fusion and reopened but no change.  Tried extruding from other areas of the base component, same result. Tried creating the 2D sketch directly on the surface of the component (without reference construction plane), no luck. For some reason it would seem Fusion will now not allow new features to be joined to this component.

Was finally able to extrude the boss and have it join with the component named "Frame".  Frame is a component within another component named "Hand".  I had activated "Hand", created the zero-offset plane and on this plane created the 2D sketch from which I was trying to extrude-join the boss to "Frame".  I activated "Frame", created an offset plane and sketch and the extrude worked as expected, joined to the base component "Frame".  Interesting nuance when working with nested components.

Yes, that is the main way to do this.  The other approach is to keep "Hand" activated as you have in your screencast, but while the Extrude command is active, you can also temporarily activate "Frame" as a way to indicate that you really want to join to the Frame component:

After you OK the Extrude, it will return to having Hand as the active component.
