Method of creating drafts with an intelligent drawing-board and drawing-board for applying this method

摘要

When making a sketch by means of a stylus on a drawing surface, the track of the stylus is detected by a measurement system and passed onto a computer, which generates a computer-internal representation of the sketch, which is imaged by means of a plotter without noticeable parallax from behind through a drawing surface onto the latter, and forms the basis of the further development of a design in sequential steps. In this process, each subsequent step proceeds from the exact imaging of the computer-internal representation of the preceding design step. The intelligent drawing-board required for this consists of a drawing machine, a drawing plate, a drawing surface, a plotter, a stylus, a measurement system and a computer as well as, if necessary, a video screen, and the plotter is arranged, seen by the viewer, behind the drawing surface, so that the plotting beam is directed from behind against the drawing surface.
