AI Drawing Prompt Reference

Draw a geometric pattern demonstrating p3m1 symmetry, featuring multiple core objects and their relationships. Start by constructing a basic unit, then generate multiple units through rotation and reflection, and combine them into a periodic pattern using translation. Add several auxiliary line segments connecting key points to form a complex geometric structure, resulting in a highly symmetric crystallographic pattern.
