AI Drawing Prompt Reference
Draw a cone and change its shape by adjusting the base radius and height. Use sliders to dynamically show the cone's volume and surface area. First, draw a circle, then draw an ellipse using the circle and the x-axis. Next, translate the cone's parts using sliders. Finally, construct the cone's side view and top view based on geometric relationships.
The prompt above was compiled from the original drawing commands and is for reference only.
