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

Workflow
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

Auto-unfolding
• 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 join 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 and remove flaps easily by clicking the flaps or edges
• Reshape flaps by dragging the handles intuitively or typing the angles and height precisely
• Copy and paste the shape of flaps
• Automatically optimize the flap shape to avoid the collision
• Display the flap targets (the area where a flap should be glued to)

Styling
• Customize the color, width, and dashing of the lines
• Individually control the appearance of the cutting line, ridge-fold line, and valley-fold line
• Hide unnecessary lines manually or automatically

Release notes:
• Fixed a bug where the height of the new flaps could be incorrect
• Fixed some minor bugs
