Why Designers Draw, and Freehand Sketching

Designers draw constantly, by hand or with CAD software, for three reasons: to explore ideas, to refine them, and to communicate them to clients, engineers, and manufacturers.
Drawings range from informal free-hand sketches to formal, precise drawings like orthographic projections, each suited to a different point in the process.
In the early stages, nothing beats freehand sketching: it needs only a pen and paper, so it is fast and flexible, letting a designer jot down many ideas before committing to any.
Sketches are often annotated to capture fleeting thoughts and variations; 3D sketches convey form and proportion, while 2D ones isolate structural detail.
The trade-off is precision: a sketch carries no accurate dimensions and lacks the detail for technical analysis, so at some point the idea must become a more formal, accurate drawing.

Orthographic Projection

A formal drawing gives the accuracy manufacture demands; in orthographic projection, the lines of sight are kept perpendicular to the viewing plane, producing separate flat views, usually the front, top, and side.
Together, three views and their labelled dimensions describe an object precisely enough to make it, though they take skill to draw and can be hard for non-technical people to read.

There are two conventions for arranging the views: in first-angle projection the top view is drawn below the front view; in third-angle it is drawn above.
