What could've been an interesting Software Design course turned into a frustrating buggy, uselessly time-consuming experience because of the shitty software we had to work with (ironically). Creating diagrams in fucking Papyrus for a Java 3D engine simulator that stopped being supported 8 years ago was definitely a stupid educational choice. Instead of focussing on understanding how to effectively draw and design such systems, we spent hours and hours trying to figure out the bugs in these pieces of software and finding workarounds, because we are of course not allowed to use other tools. What a waste of time.
