[Problem to be solved by the invention]

Drawing using the drawing device with the conventional configuration described above has elastic characteristics with respect to the time required for the manufacturing process of printed wiring boards, and the characteristics differ depending on the manufacturing method. The scale of the original image was determined during the process, making the original image incompatible if the manufacturing method was different. Therefore, each time you change to a manufacturing factory with a different manufacturing method, you have to redraw the drawing, and each time you need to recreate the data by multiplying it by the scale, which increases the number of man-hours for data creation and requires multiple pieces of data. There was a problem that data management became difficult.

The present invention solves these problems, and aims to provide an apparatus that can easily manage data by eliminating the need to recreate data due to changes in manufacturing methods.
