What level of threshold of illustration do you need to reach for it to be properly said that you are drawing?

What's the analogous threshold to say you're engineering?

Art is subjective. It isn't about checking boxes and counting how many formal criteria it meets.

Engineering is broad, it uses many different methods and techniques. All I am saying is that I wouldn't call someone a mathematician if they can only find the result of 2+2.

You say art is subjective but didn't answer the question: what are the objective criteria that define engineering?
