Abstract This paper used 3ds MAX software to carry out real-time three-dimensional modeling of metal crystals. Starting with the simple cubic cell, adopted the "construction-modification-trial and error" mode to guide students to construct all the unit cells of the cubic system. In this instructional design, students were led to discover and understand the essence of the "close packing" model visually and initiatively. Finally, the relationship between cell structure and accumulation was established. The students' chemistry discipline core literacy could be significantly increased through this well-design course.
