PURPOSE: To enable a machining region drawing to be flexibly prepared while having a talk with an output picture of drawing information, by compounding machining drawing data and material drawing data to perform a shift process further manually or automatically dividing or eliminating a region.
CONSTITUTION: A CPU1, which fetches parts drawing and material drawing data Ma, Mb from a CAD unit M if a process data and a command are input from a keyboard 2 with screen, sets a relation between both coordinate systems of the data in a setting part 72 while registers a desired region of machining shape and material shape in processing parts 73, 74. Next the CPU1 registers a desired region by compounding the both shapes in a processing part 75, and the CPU1, which in a processing part 76 moves a shape element of the region on the basis of a previously created shift amount and direction while in a processing part 77 divides or deletes the region by manual or automatic instruction command, prepares a region drawing data 20. In this way, the region drawing data can be promptly further flexibly prepared by a talk process with and an automatic process of an output picture of drawing information.
