摘要： A plotting device is disclosed containing a traveling carriage drawing apparatus and distance measuring devices in the traveling carriages which emit a number of electrical pulses which are proportional to the displacement of the traveling carriages and which are weighted with an adjustable scale factor, to be measured as coordinate values (x, y) of a basic Cartesian basic coordinate system. The measured coordinate values are transmissible to and recordable by indicator units located within the area of a traveling carriage. The basic coordinate system possesses a selectable, stationary zero point and fixed axis directions in the traveling direction of the traveling carriages. In order for the user to obtain, through appropriate collection and processing of coordinate values which are actually being plotted, the information required in a form particularly suited for the preparation and dimensioning with respect to execution of the drawing, and which specifically is CAD-compatible as well, conversion means are provided which transform the measured coordinate values into the values of a desired different coordinate system. In addition, there is provided a control unit with selector button array to allow selection of the desired coordinate transformation and to transmit the measured or transformed coordinate values, as desired, to the indicator units.
