If it was drawn on paper, for example, the artist can turn the page and. This process will depend on how exactly your tessellation was made. The point can be a corner of the tessellation, anywhere along a side or at a point that is not a part of the tessellation. Furthermore, for a metasheet with a fixed number of units, all the geometrically compatible tessellations can be folded out of the same pre-creased sheet material by simply changing the mountain–valley assignments, thereby allowing the properties of the metasheet to be re-programmed based on specific requirements. Select the point that you want to rotate your figure around. Based on this, we are able to program the mechanical properties of the metasheets over a wide range by varying the types and proportions of the units, as well as their geometric and material parameters. We demonstrate through experiments that the energy, initial peak force, and maximum stiffness of the metasheets can be obtained by a summation of the properties of the constitutional units. The tessellation rule of these metasheets is established to allow compatible mountain–valley crease assignments and geometric parameters among neighboring units. In this paper, we propose a new kind of origami metasheet by incorporating a family of different square-twist units.

Select the shape tool on the tool palette, select the rectangle shape, select a color and make sure the filled option is selected. Use the New button to create a blank project. However, the geometric design rules and property programming methods for such metamaterials have yet to be extensively explored. You can use Wixie’s paint tools to create a rotation tessellation. In the first example at right, the golfish turns 120 degrees, then does it again, to make three fish in each cluster. Metamaterials constructed from origami units of different types and behaviors could potentially offer a broader scope of mechanical properties than those formed from identical unit types.
