I read many comments and came to the conclusion that AD was only intended to create digital environments. In general, the program and the interface are very clumsy at the time of preparing documents for printing. Being able to see the bleeding line is basic and it should not be necessary to invent systems such as putting a square with transparency and line and then removing it.
It is not the way. This function is standard in all programs of this type.
No need to invent anything new. Too much time waiting for a vital improvement.
