Drafting tools may be used for measurement and layout of drawings, or to improve the consistency and speed of creation of standard drawing elements. Tools such as pens and pencils mark the drawing medium. Other tools such as straight edges, assist the operator in drawing straight lines, or assist the operator in drawing complicated shapes repeatedly. Various scales and the protractor are used to measure the lengths of lines and angles, allowing accurate scale drawing to be carried out. The compass is used to draw arcs and circles. A drawing board was used to hold the drawing media in place; later boards included drafting machines that sped the layout of straight lines and angles. Tools such as templates and lettering guides assisted in the drawing of repetitive elements such as circles, ellipses, schematic symbols and text. Other auxiliary tools were used for special drawing purposes or for functions related to the preparation and revision of drawings. The tools used for manual technical drawing have been displaced by the advent of computer-aided drawing, drafting and design (CADD).

👉 Technical drawing tool in the context of Compass (drafting)
A compass, also commonly known as a pair of compasses, is a technical drawing instrument that can be used for inscribing circles or arcs. As dividers, it can also be used as a tool to mark out distances, in particular, on maps. Compasses can be used for mathematics, drafting, navigation and other purposes.
Prior to computerization, compasses and other tools for manual drafting were often packaged as a set with interchangeable parts. By the mid-twentieth century, circle templates supplemented the use of compasses. Today those facilities are more often provided by computer-aided design programs, so the physical tools serve mainly a didactic purpose in teaching geometry, technical drawing, etc.
Technical drawing tool in the context of Rotring
Rotring (stylized rOtring) is a manufacturer of technical drawing tools and writing implements. Established in Germany in 1928 as a fountain pen manufacturer, Rotring went on to be acquired by Newell Brands in 1998. The name "Rotring" directly translates to "red ring", which refers to the company's signature: a red band placed around the barrel of the pen. The company's name was changed to Rotring in the early 1970s to match the trademark.
Since the Rotring factory and headquarters in Hamburg were shut down, production has been handled and distributed by Japanese manufacturer Holbein and other manufacturers.
