Unfolder is a 3D model unfolding tool to help you create papercraft easily and quickly.

Personal observation: Mac native, perfect OSX look and feel, beating Pepakura and Blender's export in ease of use and customization. Exports 3D models to paper folding or CNC. It also syncs with Blender and Cinema4D, and soon with Maya. .

1. Create a 3D model in any 3D editor

2. Unfold the 3D model into a 2D template in Unfolder

3. Print the template out to make your papercraft by cutting, folding and gluing

Importing and Exporting

Import 3D objects in OBJ format

Sync 3D objects with Blender and Cinema 4D in one click

Partially update the imported objects

Supports materials and textures

Export templates in PDF, DXF, SVG, or PNG format


Generate 2D patches for your 3D models in a few seconds

The algorithm is highly optimized for papercraft to minimize your effort in further editing

Editing Patches

Move, rotate, align, and distribute patches

Split and joint patches easily by clicking the edges in 2D view or 3D view

Generate paper-saving layout automatically

Highlight overlapping or overflowing patches

Adjust the size of your papercraft by typing the dimensions you want

Editing Flaps

Switch, add or remove flaps easily by clicking the flaps or edges in 2D view

Reshape flaps by dragging the handles intuitively or typing the angles and height precisely

Copy and paste the shape of flaps

Automatically detect and fix the flap problems, such as overlap and overflow

Display the flap target (the area where a flap should be glued to)


Customize the color, thickness, and dashing of lines

Individually control the appearance of the cutting line, ridge-fold line, and valley-fold line

Hide unnecessary lines manually or automatically
