A data drawing method which facilitates the checking of numerical control data for a polyhedron machining and is carried out by, for example, an automatic programming system. If a drawing mode is selected in which machining profiles and tool paths related to individual machining surfaces of a polyhedral material are displayed separately on a display screen according to the machining surfaces, and if a processor of the programming system determines that NC data obtained by executing a program statement read from a part program is related to any one of the machining surfaces, drawing areas corresponding in number to the faces of the polyhedral workpiece on the display screen are displayed, and a character string representing the machining surface and a material profile in a drawing area corresponding to the machining surface are displayed. Then, machining profiles and tool paths specified by the produced NC data are displayed in the drawing area to permit the operator's visual checking. Machining profiles and tool paths related to another machining surface are displayed in a different drawing area, whereby the machining profiles and the tool paths can be easily checked.
