Not ‘just’ doing a bit of work with CAD software…
That would be a designer/draughtsman, depending on how much autonomy is given.
The engineer is the person behind the design, who’s done the required calculations, be it mechanical strength, thermal efficieny, or cost and production time or whatever to make sure whatever it is will work correctly for the given situation.
an engineer is someone who physically builds stuff like steam trains or something. Machining stuff to designs, assembling, fixing
Again, depends on the autonomy. If they’re assembling or machining to a detailed drawing, they’re not engineers. If they’re having to fix shoddy designs as they build, then they are.
So actually, by the definition that you want to apply, you’re not. Yet
I’m an engineer. Not an Engineer. 🙂 (but give me 3 months….)
