PURPOSE:To save the man-hour by reducing copying work, making the state at the original position of a graphic under preparation to be easily grasped and preventing the generation of an extra graphic due to a projection when a graphic preparation and a graphic calculation are continuously performed on the same partial coordinate system. CONSTITUTION:This processor is composed of a CPU, a memory, a CRT, a mouse, etc., and is provided with an operation program having steps 60 to 62 and 70 to 72 storing coordinate system information defining plural partial coordinate systems performing two-dimensional works, respectively, and switching a coordinate system for work to one partial coordinate system selected from plural partial coordinate systems, steps 80 to 84 automatically coordinate transforming an inputted two-dimensional coordinate value to the dimension within the coordinate system for work and storing it, a step 86 performing a graphic preparation based on a stored two-dimensional coordinate value, steps 90 to 94 automatically projecting an instructed graphic on the coordinate system for work and storing it and a step 96 performing a graphic calculation based on the stored graphic.
