Abstract The concept, classification, properties of projection and the establishment of three-plane projection system are briefly introduced. Use the orthographic projection method to convert the three-dimensional unit cell into a plane projection; With the help of the fourth sub-question of the 18th question of the 2022 Hunan Provincial General High School Academic Level Selective Examination, this paper discusses how to restore the plane projection to a three-dimensional unit cell. At the same time, the authors put forward their own opinions on the design of the test questions.
