It would be really useful if Fusion would inform you where a part is being referenced, when it prevents you from deleting it. At the moment the only information you given is the prompt "it cannot be deleted because it is being referenced by other components. When I delete this component form all of my assemblies, however, I still get this alert and cannot get around it. A simple list of the references with the prompt would make removing all references a lot easier, and simplify deleting components.
Thanks 🙂
