Abstract

PURPOSE:To reduce the time for allocating a die and to improve the quality of data by interacting with a graphic presentation on a CRT. CONSTITUTION:When an initial command is inputted from a keyboard 2 to a storage/processing part 4, a die data read part 41 and a graphic data read part 42 read out each data file 51, 52 of the die and graphic of a disk device 5 in sequence and to output the data to the CRT 1. An object element for allocating the die of a finished part is specified from a two point picking of a mouse 3 to a graphic data outputted to the CRT 1. In an extracted element, a two point picking of the same point is treated into a one point mode and two point pickings of a line segment, a circular arc, a continuous internal polygonal element are treated into a two point mode. In case of the one point mode, after the allocating state outputted by the input of the offset value ( X, Y) of a reference point and the selection of the die to the CRT 1 is confirmed, it is written in a die allocating data file 53 to make a graphic display of the allocated state.
