I have an assembly that I dragged in components from the data panel. The components appear with a link on them as expected. Just like in solidworks, if I make changes to the model elsewhere it updates in the assembly. However, unlike Solidworks I'm unable to modify the components from within the assembly. My workflow consists of modifying components in the context of other components but I'm unable to do this. The only thing I can do is right click > open and modify the component on its own.
In assemblies that have components that are local and not linked I'm able to activate them and edit them in context.
