Package relationships

Anyone know how to model relationships between packages (with sub functions and procedures) ?

I've just inherited a huge project with 20+ years of spaghetti pl/sql. I've started making a diagram manually in a third party program, but it's tedious and not dynamic. Any better ideas?

Hello Toed,
unfortunately this feature (package relationships) you are requesting is not supported in Toad Data Modeler. If you have an idea, you can create user request in our Idea Pond.
