# Die Line

Creates a flat packaging template (die line) based on a product image — the unfolded box layout showing panels, fold lines, and cut lines.

#### How to use

Die Line is a **mode within the Packaging tool**. Open **Packaging**, upload your product image, set **Mode → Dieline — flat unfolded template**, then click **Generate** (3 credits).

#### Tips

The AI estimates packaging proportions based on your product. The result is a clean technical drawing with fold lines (dashed) and cut lines (solid), suitable for manufacturing reference or further refinement in Illustrator.
