TETRAHEED PERSPECTIVES & CONCEPTS
Suppose I show you this simple drawing and ask, "What is it?"
How would you answer? What do you think it is?
When I show this drawing to people, the most common answers they offer are either:
(1) a guess, such as, "A set of drawers, with one handle missing", or
(2) a literal answer, such as, "Two rectangles, with a third smaller rectangle inside the lower one."
Both of those are entirely reasonable answers.
But a better answer would be, "I don't know. No one can reliably tell, from just this one drawing, all by itself."
So, then I draw two more views of the exact same object, lined up in a way that is standard in so-called "engineering drawings".
