An Autodesk® Fusion 360™ add-in that warns when features are created outside components. It also warns when creating a feature across components (It works if the reference feature is selected before creating the new feature).
A warning will be shown every time a new feature is created at the top-level or in the wrong component. At that point, the user can choose to either Cancel, Continue or Stop the warning messages for the current document session.
This add-in is free, but if you like it, you can buy me a coffee (Ko-fi link).
