PURPOSE:To easily prepare the line graphic and road graphic of a free curve. CONSTITUTION:This device is equipped with a CPU 104 constituted of a arithmetic processor 107 which operates a plotting processing, a memory 108 which stores data necessary for a program or a processing, and an interface circuit 109 which performs connection with an external device, a coordinate inputting device 101 which inputs coordinates, an external storage device 102, and a display 103 which displays data on a screen. The CPU 104 is equipped with the arithmetic processor 107 which performs the plotting processing, and the memory 108 which stores the data necessary for either a plotting processing program or the plotting processing of a part graphic, and the line graphic is prepared by successively plotting the part graphic. Also, the road graphic is prepared by plotting one curve by overlapping a circular graphic A on a circular graphic B in a different color which is smaller than the circular graphic A. |
