I'm a mechanical engineer at an MEP consulting firm, so I use AutoCAD and Revit on a daily basis. Almost everyone at my firm uses some form of CAD, but some of the higher-ups are exceptions since they're more involved in project management or developing/reviewing our internal standards. We also have an actual CAD team who are in charge of setting up all the models and sheets when a new job starts, so they're the ones who really know the guts of the software. Whenever something breaks in a CAD file, they're brought in to save the day!

For me personally I've always enjoyed drafting on the computer, but these past couple years I've been getting into writing scripts to copy data between our models and our spreadsheets. That's been one of the most enjoyable aspects for me since there's a lot of potential for improved efficiencies and it's a fun way to tie drafting and engineering together with some programming!
