8. Learning a new Language
“Engineering Graphics”
A fully developed language in its own right
A graphical language that engineers all over the world understand regardless of their native tongue
Used to describe physical objects (existing or yet to come) via drawings and renderings
Has rules (just like any other language) – alphabets and grammar
With a new language, comes a new culture
Or vice-versa?
