One of the usefulness of drawingUML ourselves (as oppose to rely on automatically-generated ones) is to track classes growth (it's numbers, associations among themselves). It's refreshing to occasionally pause a little from coding work and update those dusty old diagrams that we've updated last week/month. It helps us to review and maintain the integrity of the code and, somehow, feel still in control of all of it.
There are things that does not appear on source code or IDE in apparent manner and without tracking in high level view there can be trouble related to conceptual integrity of the code that creep up and accumulate over time. Even with lots of features that help to get a high level view of classes e.g: ctag-based tools, or automatically generated diagrams, nothing can replace manually-drawn visual diagram role on this.
Somehow it's not really about the diagram itself but the act of clarifying what's inside our head in a more visible manner for us to digest, the byproduct, the diagram, is just a nice bonus. It's not really the diagram that we've updated but it's our view about the whole thing that got refreshed periodically. It gives fresh view and the feel that we are still in-touch with the code. Also, in the process where we see, stare (and reflect) on associations that could fuel another insights, breakthroughs or just clarifying our already-outdated understanding.
Conceptual integrity can deteriorate over time and taking occasional visual view could help in dealing with it.
