The Yoshizawa–Randlett system is a diagramming system used to describe the folds of origami models. Many origami books begin with a description of basic origami techniques which are used to construct the models. Several standard bases are commonly used as a first step in construction. Models are typically classified as requiring low, intermediate, or high skill depending on the complexity of the techniques involved in the construction. The concept of diagramming originated in the 1797 book “Senbazuru Orikata”, the first origami book ever published. The diagrams in this book were very unclear, and often only showed the result of the folding process, leaving the folder unsure of how the model was created.

Origami symbols-The operations

In the 1950s and '60s, Akira Yoshizawa proposed a system of diagramming. He introduced its diagramming notation in his first published monograph, Atarashi Origami Geijutsu (New Origami Art) in 1954. He employed dotted and dashed lines to represent mountain and valley folds, and a few other symbols such as the “inflate” and “round” symbols. This system caught the attention of Samuel Randlett and Robert Harbin, who added a few symbols such as “rotate” and “zoom in”, and then adopted it as the standard. The Yoshizawa–Randlett system was first described in Samuel Randlett's Art of Origami in 1961.[1] It was then accepted as the default throughout the international origami community and is still in general use today.
