We welcome suggested improvements to any of our articles. It was sutherlznd general purpose system and has been used to draw electrical, mechanical, scientific, mathematical, and animated drawings.
Starting with his Ph. Sketchpad was the first program ever to utilize a complete graphical user interface. Sketchpad drawings are stored in the computer in a specially designed “ring” structure.
Geometric constraints is another major invention in Sketchpad was that it let the user easily constrain geometric properties in the drawing—for instance, the length of a line or the angle between two lines could be fixed. A Sketchpad user sketches directly on a computer display with a “light pen. Classical musicians have long had a reputation for being the wo Sketchpad was able to do just this, creating highly precise drawings, and also introduced important innovations such as memory structures to store objects and the ability to zoom in and out.
