Fusion 360 Component Appears in Wrong Spot
The component is nested under the wrong component in the Fusion 360 Browser.
New Components will always be placed underneath whichever component is currently active in the Browser - unless, you select the "parent" when creating the new component.
You'll see the following dialog when creating a new component.
Notice the Parent selector (circled in orange). This will default to the active component. However, select the "X" to clear the selected parent and select a new component in the Browser. This allows you to create a new component at the appropriate location, without the need to activate the parent component.
