AI Drawing Prompt Reference

Create a dynamic illustration of a cylinder torsion, showcasing 3D vectors and surfaces. Begin by drawing two circular curves to represent the top and bottom faces of the cylinder, then generate a twisted surface using these curves, and finally sketch the boundary lines of the surface to highlight the torsion effect.
