There's that sadism flaring up again
The wonderful thing about high school, for most people, is the fact that it ends.
There are many benefits to drawing things up in CAD.
The primary one is "sharing".
I can share these CAD files with others, and they can manipulate and build upon them if they want. So that they don't have to waste their time redrawing what you just drew up in order to make something new and interesting.
You are either behind this idea or against it, and everything flows from there down.
