The main idea was to have master drawings which one could instantiate into many duplicates. The clever way the program organized its geometric data pioneered the use of 'master' ('objects') and 'occurrences' ('instances') in computing and pointed forward to object oriented programming. Sketchpad was the earliest program ever to utilize a complete graphical user interface.

Software The geometric data or 'N-component element' for a straight line is composed of addresses to two other N-component elements representing the end points of the line, which each contain an X and Y coordinate. See History of the graphical user interface for a more detailed discussion of GUI development. Sketchpad inspired Douglas Engelbart to design and develop oN-Line System at the Augmentation Research Center (ARC) at the Stanford Research Institute (SRI) during the 1960s. Sutherland was inspired by the Memex from ' As We May Think' by Vannevar Bush. Using the program, Ivan Sutherland showed that computer graphics could be used for both artistic and technical purposes in addition to demonstrating a novel method of human–computer interaction. For example, the graphical user interface (GUI) was derived from Sketchpad as well as modern object-oriented programming. It pioneered human–computer interaction (HCI), and is considered the ancestor of modern computer-aided design (CAD) programs as well as a major breakthrough in the development of computer graphics in general. Robot Draftsman ) is a computer program written by Ivan Sutherland in 1963 in the course of his PhD thesis, for which he received the Turing Award in 1988, and the Kyoto Prize in 2012.
