I am aware that one could run the ERD import sequence of actions to obtain a CSV/TSV file with all the schemas, tables, fields and their relationships/constraints.
Instead of selectively dragging and dropping the tables from the lower-left corner onto the canvas, I'd like to use a single command to dump all the tables onto the canvas and create the conceptual level ERD, i.e. without the fields. Just the table names and their relationships (with the respective cardinalities).
I am aware of the ability to reduce the number of displayed fields, but it's too slow for my initial purposes. What I am trying to achieve is a "first look" at the complexity and interconnectedness of a reverse-engineered database with minimum manual effort.
How can this be achieved, if at all?
