Hi, first post here, I'm wondering, does anyone actually use uml diagrams? I completed a course in first year, apparently "system analysis and design" means draw uml diagrams all class, then draw more later, without ever actually touching a text editor.

They can be useful

I use plantuml from time to time

When you start working in teams and need to communicate ideas or explain how something works effectively they will become really useful. You'll spend a lot of your time drawing diagrams on a whiteboard and discussing ideas so it really is a useful skill to have, even if it's a bit boring to learn.
