<p>PURPOSE:To input all figures on a drawing even if the space is not enough for the entire drawing, by shifting the drawing to input parts of figures successively and converting coordinate values of points to data of the same coordinate system. CONSTITUTION:Coordinates (x01, y01) and (x02, y02) of specific points before the shift of the drawing are stored in registers 101a and 101b respectively, and coordinates (x11, y11) and (x12, y12) of specific points after the shift of the drawing are stored in registers 101c and 101d respectively. In this state, when coordinates (X1, Y1) of a prescribed point are inputted from a tablet device 102 to a register 101e, a coordinate converting device 103 performs a prescribed operation to convert coordinates and outputs the result (X', Y'). When coordinate values X' and Y' are outputted, an NC data generating device 104 uses them to generate NC data, and this NC data is stored in a data memory 105. If it is necessary to shift the drawing over and over again, coordinates of specific points after every shift of the drawing are set in registers 101c and 101d to perform the similar coordinate conversion.</p> |
