The material shape is displayed on the screen of the CRT 9 according to the program.If the magnification P is "1", the material shape is displayed on the CRT screen, and P = 0. If it is 5, then the length of one side of the material shape when P = is set will be displayed in half the size, and by changing the magnification P, it will be displayed on the CRT screen. It can be displayed in any size.
