The Shape Tool allows you to quickly create geometric forms - ideal for blocking out concepts, roughing in design elements, or guiding AI to generate clean, structured assets. It works especially well when paired with selection and prompt tools to refine your output.
Learn how to block out ideas with the Shape Tool, guide AI with a prompt, and iterate without losing your base design.
Overview
Use the Shape Tool to draw basic shapes directly onto your canvas. These can act as placeholders or rough sketches for new elements you want to generate with AI. Once drawn, your shapes can be selected, prompted, and used to create entirely new assets.
How It Works
 | Select the Shape Tool from the toolbar. Choose a color using the color wheel or color picker to define your shape’s fill. |
 | Draw shapes directly on the canvas. These can represent objects, props, UI elements, or any basic structure you want to build upon. Use the Lasso Tool to select the shape(s) you've created. |
 | Write your prompt, describing what you want the AI to turn those shapes into. |
 | Lower the Similarity setting below 50 to give AI more flexibility when transforming your simple shapes into detailed assets. |
 | Click Forge in Selected Area to generate multiple outputs. |
 | Review the results and Accept your preferred output onto a new layer to preserve the original shape. |
Best Practices
Use basic shapes to rough in layout or structure before turning to detailed AI generation.
Lower similarity to encourage interpretive, creative results from the AI.
Accepting the result on a new layer allows for non-destructive iteration while maintaining your base idea.
Combine with tools like Lasso and Brush for more complex prompts and refined selections.
