AI Drawing Prompt Reference

Draw a modular section of a cube focusing on triangles. Start by creating a circle on the base plane and derive points from it, then rotate to form the cube's faces. Identify midpoints of faces and line segments, connecting them to form triangles. Translate these triangles using vectors and draw lines between midpoints to complete the geometric illustration with multiple triangles and cube faces.
