long, long, very long time ago…

but not that long ago…

people expressed their IDEAS through

Sketches and paintings…

How ART got formalized !

Bottomline

• ‘DESIGNERS’ may have been a single person or a team of few

• ‘DESIGNERS ’ were ‘multi-faceted’ – they practised many other avocations out of ‘Choice’

• Design HAD TO BE COMMUNICATED to those building it (‘MANUFACTURERS’)

• COMMUNICATION could have been possible only through ‘SKETCHES’ or ‘DRAWINGS’

Gaspard Monge, 1746-1818

Engineer in French Military

Inventor of ‘descriptive geometry’

Pictures, sketches were used to communicate butdidn’t have any uniformity

Architects, builders, engineers, designers had difficulty in understanding figures

One could draw figures in various ways

Monge formalized the TECHNICAL drawings,what we know as ORTHOGRAPHIC PROJECTIONS.

The scheme was quickly adopted by army Engineers, and after the war, it was accepted worldwide and formed the back bone for INDUSTRIAL REVOLUTION

OBJECTIVE: To Learn TECHNICAL DRAWING in THEORY and PRACTICE using drafting tools and free hand sketches
