Abstract

A three-dimensional figure data generator device for a numerically controlled machine tool, etc., includes a two-dimensional figure definer/editor unit and a two-dimensional view data setter unit. The two-dimensional figure data and the two-dimensional view data are stored in a two-dimensional figure data memory and a two-dimensional view data memory, respectively, with identifying data numbers. When a two-dimensional figure element is specified on the screen, the data number thereof is determined from the display region of the figure element, and the corresponding projection direction and two-dimensional figure data are retrieved from the two-dimensional view data memory and the two-dimensional figure data memory, respectively, such that the three-dimensional figure data for the figure element can be generated.
