At this time, the dark lines on the first image receiving surface 1 are solid lines, and the light lines are dotted lines, and the plane image of the object can be displayed;

[0031] S4, front elevation projection, the second image receiving surface 2 is placed in front of the object, the parallel light source is placed behind the object, the power is turned on, and the projection is performed; the light penetrates the plane, and the plane has almost no shadow on the second image receiving surface 2; the light passes through the edge of the semi-transparent acrylic plate material, and light lines appear on the second image receiving surface 2; the light passes through the edge of the opaque material, and dark lines appear on the second image receiving surface 2. At this time, the dark lines on the second image receiving surface 2 are solid lines, and the light lines are dotted lines. The front elevation of the object can be displayed;

[0032] S5, left side elevation projection, the third image receiving surface 3 is placed on the left side of the object, the parallel light source is placed on the right side of the object, the power is turned on, and the projection is performed. The light penetrates the plane, and the plane has almost no shadow on the third image receiving surface 3; the light passes through the edge of the semi-transparent acrylic plate material, and light lines appear on the third image receiving surface 3; the light passes through the edge of the opaque material, and dark lines appear on the third image receiving surface 3.
