It's more than just drawing, it's visualization.  
"A pencil is a great eye".

Graphical communication has been used for hundreds of years...

Prehistoric drawings...

architectural drawings in ancient Greece and Rome...

 

Leonardo di ser Piero da Vinci;
April 15, 1452 – May 2, 1519, - an Italian Renaissance polymath  revered for his technological ingenuity. He conceptualised flying machines, a tank, concentrated solar power, an adding machine, and the double hull, also outlining a rudimentary theory of plate tectonics. Relatively few of his designs were constructed or were even feasible during his lifetime, but some of his smaller inventions, such as an automated bobbin winder and a machine for testing the tensile strength of wire, entered the world of manufacturing .  He made important discoveries in anatomy, civil engineering, optics, and hydrodynamics.

Old School Drafting Instruments:

Supplies needed for class:

3 ring binder with dividers.
Pencil & eraser:

• - .5 mm, or H / 2H lead
• - If you bring in a wooden pencil, also bring a pencil sharpener.
• - eraser: you will need more than what is on the end of your pencil.

Ruler, compass, protractor.

• We won't be spending too much time on manual drafting, so don't spend a bunch of $ getting anything fancy - the dollar store is fine, but do get some basic tools!

Paper:
- Notebook paper (for taking notes with)
- Printer paper (or E- paper) for sketches.

3 hole punch

Engineering paper:
  If you can't find any E-paper, that is ok, just so you know what it is - graph paper engineers commonly use because it makes sketching easier.

Technical communication in the Information Age:

link -

Verbal Communication:

Meetings, presentations, conferences, discussions, conversations, etc.

Written Communication:
Proposals, Reports, Memos, Notes, Emails, Lab Books, etc.

What is the difference between technical and liberal arts communication styles?

What roles do engineering drawings play in the communication process?



What is the difference between a technical drawing, and traditional art?
Precise communication distinguishes technical drawing from visual arts.

• Artistic drawings are subjectively interpreted; their meanings are multiply determined.

• Technical drawings have one intended meaning.

Example diagrams:

Mechanical Engineering:

 

 
Civil & Structural Engineering:






Offshore Rig (Chem and petroleum Engineering)

Rules of the game:

To make the drawings easier to understand, people use familiar:
 

• symbols


• perspectives (partial views, half views)


• units of measurement (imperial, metric)


• notation systems


• visual styles


• page layouts

• lettering


• lines


•  Surfaces


• Materials

Together, such conventions constitute a visual language, and help to ensure that the drawing is unambiguous and relatively easy to understand.

Standards, or conventions, or industry standard - a set of technical definitions and guidelines that function as instructions for designers, manufacturers, operators, or users of equipment.  These are commonly used approaches without any formal documentation behind it.

Code - A standard becomes a Code when it has been adopted by one or more governmental bodies and is enforceable by law, or when it has been incorporated into a business contract.

Various disciplines; electrical, electronic, pneumatic, hydraulic, etc., have industry recognized symbols to represent common components.
