Abstract: A device for displaying CAD drawings with a plotter, substantially consisting of a mounting for a plotter pen, such mounting being movably guided in accordance with a program in two coordinated directions relative to a drawing carrier. The drawing carrier is arranged in a frame and is embodied in the form of a board or foil with a surface, or layer to which the ink of the plotter pen adheres only temporarily and is removable again by means of an erasing device.
