4H-Unfolder Wiki

Turn a 3D model into a printable paper pattern — load a mesh (.obj / .pdo), unfold it into flat 2D pieces with glue tabs and fold lines, then export to SVG or PDF for cutting and folding into a physical papercraft model.

📸 Demo GIF placeholder — import → auto-unfold → export PDF. Add docs/demo.gif and embed it here.

What this wiki covers (and what it doesn't)

This wiki is for how to use the app and long-form explanations. Quick reference — feature bullets, build one-liners, the layered architecture — lives in the README and is not duplicated here; pages link back to it instead.
