AI Drawing Prompt Reference

Create a 3D geometric shape to demonstrate its construction and transformation. Start by drawing two circles and marking points on them, then connect these points with line segments. Perform rotations and calculate angles to generate new points and segments. Use rays and find intersections to determine key positions, forming closed polygons. Add additional circles and rays to create a complex geometric structure, fully showcasing the construction and transformation of the 3D shape.
