### Could someone explain me what 'box pleating' is all about ?

What exactly is 'box pleating' ?

Can someone give me an exeample and/or diagram of a model which ilustrates that concept (or should I say technique) ?

The most complicated definition can be found on Robert LangÂ´s site:
a style of folding characterized by all folds running at multiples of 45Â°, with the majority running at multiples of 0Â° and 90Â° on a regular grid.

A very long article about box-pleating by Marc Kirschenbaum can be found here: http://contract.home.pipeline.com/ELIAS.htm

An example-diagram would be Jeremy ShaferÂ´sStar of David or Mario Adrados NettoÂ´sDama.

While googling I had read those definitions, but I what I understood was nothing. IÂ´ll try to read KirschenbaumÂ´s article more carefuly later. And IÂ´ll check those diagrams too.

You can try this out for yourself by first precreasing a square into eighths, both vertically and horizontally. Take the square, and pleat it together like a fan, with the coloured side on the exterior. Hold the fan shape in the upright position, looking at the white side, and grasp the top two original corners. Pull these corners apart from each other, and begin to fold them in half along their diagonals. These folds should terminate at the first interior crease (which in this case is 1/8 inwards). Next, bring the top edge down. If you turn the model over, and treat the interior rectangle as in the previous steps, the top corners of the square will begin to become distinct appendages. Repeating this iterative process until there is nothing left to stretch, will give you two long appendages on top, and a fan-like appendage at the bottom. It is noteworthy, in this instance, repeating the stretching procedure on the fan-like appendage will result in the equivalent of a waterbomb base sunk into fourths.
I wish I could understand that part. That should ilustrate what box-pleating is for and how it works. From what I could understand that technique allows us to make as many appendages as we wish.

OK, IÂ´ll try to explain.

First of all a little example:

Box pleating is a technique using a fan-like folding process to separate layers or thin the apearance of a model. In the example above you can see how the two top corners become free layers usuable as arms or legs or whatever you want. This technique is great for creating most complex and stunning looking designs like Hojyo TakashiÂ´s human figures.
A very straight forward box pleating design is Brian ChanÂ´s Dobsonfly.

Thanks Anna, I think I get it now !
Actually, I think I have already folded one model that uses this technique:
