Nets which can be folded to 3 distinct boxes
From the same unfolded pattern, you can make three different boxes!
In the 3D window of Pepakura Designer, you can see three boxes with different shapes.
However, the three unfolded patterns shown in the pattern window all have the same shape.
This very interesting fact was researched by Prof. Uehara.

Using the animation function in Pepakura Designer, you can observe how the same pattern transforms into different boxes.
