Sutherland: Sketchpad graphical communication system

What changed

Interactive computer graphics became a working medium for structured geometric design.

Scientific scope

Sutherland's 1963 thesis and system; later CAD, GUI and object-oriented software are distinct.

Evidence

The linked sources identify this contribution and its scope. WRS has not independently reconstructed the scientific claims. The target is Sutherland’s 1963 MIT doctoral thesis and system. Later CAD, GUI and object-oriented systems are consequences or extensions, not part of this exact record.
