How to generate a 3D model in AI tools?

To generate a 3D model in AI tools, start with an input (text prompt, image, or 2D sketch) and let the AI convert it into a 3D mesh or model using algorithms like NeRF or GANs. The AI interprets your input to add details (e.g., texture, geometry), and most tools let you refine results via parameters (resolution, style) or direct edits. For beginners, use simple prompts (e.g., "a blue mug") in tools with guided workflows—this helps you learn how the AI responds before trying complex ideas.
