Same here, late 80s I took a high school drafting class and asked about the PCs in the back, the teacher said "I don't know anything about them, they have some software called AutoCAD. Do you want to take an elective and learn how it works?" It was entirely 2D and I went through all the exercises quickly.

That foundational knowledge stuck with me and although it's not my job at all, I use Fusion 360 all the time at home to design parts for my self-built microscope and many other things. It's a great tool.
