Sketchpad included 17 different types of constraints, including vertical, horizontal, perpendicular, coincident, parallel, aligned, equal size, and more.

Sketchpad proved beyond doubt that computers could automate repetitive design and drafting tasks with a reliability and accuracy not possible by manual methods. Since Sketchpad is able to accept topological information from a human being in a picture language perfectly iban to the human, it can be used as an input program for computation programs which require topological data, e.

Sketchpad – Wikipedia

Sketchpad has shown the most usefulness as an aid to the understanding of processes, such as the notion of linkages, which can be described with pictures.

His company Evans and Sutherland founded together with his friend David Evans has done pioneering work in the field of real-time hardware, accelerated 3D computer graphics, and printer languages.


How objects in Sketchpad could be visualized and modeled on a screen became the foundation for modern graphical computing used in advertising, business, entertainment, architecture, and Web design.
