[6]: 35–36 A drafting machine allows easy drawing of parallel lines over the paper. The adjustable angle between the rulers allows the lines to be drawn in varying accurate angles. Rulers may also be used as a support for separate special rulers and letter templates. The rules are replaceable and they can be for example scale-rules.
As the device is designed for drawing lines on paper, it can produce tables and ruled paper. The functionality of the machine is based on pens manufactured especially for the device. The pens have multiple tips side by side, and water-based ink is led into them along threads.
Initially, paper was ruled by hand, sometimes using templates. [1] Scribes could rule their paper using a "hard point," a sharp implement which left embossed lines on the paper without any ink or color, [2] or could use "metal point," an implement which left colored marks on the paper, much like a graphite pencil, though various other metals were used.
Using a markable ruler, regular polygons with solid constructions, like the heptagon, are constructible; and John H. Conway and Richard K. Guy give constructions for several of them. [20] The neusis construction is more powerful than a conic drawing tool, as one can construct complex numbers that do not have solid constructions.

A ruler, sometimes called a rule, scale or a line gauge or metre/meter stick, is an instrument used to make length measurements, whereby a length is read from a series of markings called "rules" along an edge of the device.

The 6-step. The 6-step is foundational to b-boying not only because it is the first footwork sequence breakers often learn, but also because it remains the move around which many sets are structured. Many break moves can begin from the 6-step. The move sets up the direction of rotation and builds momentum while imparting body control. The ...

The resulting image is a negative print of the hand, and is sometimes described as a "stencil" in Australian archaeology. [ 10 ] Miniature rock art of the stencilled variety at a rock shelter known as Yilbilinji, in the Limmen National Park in the Northern Territory , is one of only three known examples of such art.
