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. 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.

Many drawing tools are used for drawing, draughting and design. Drawing tools may be used for measurement and layout of drawing. They include pens, pencils, rulers, compasses, protractors and other drawing utilities.

In this paper, I am going to familiarize you with the Engineering Drawing Instrument. So let's dive into the article.

Before we can use innovative products and technical developments, they need to be constructed. That is what technical drawers do. A new building, the engine for a vehicle or a production facility for a company — architects, engineers or graphic designers take all of the measurements and make sure all of the dimensions are laid out correctly. Even though nowadays a large part of their drawings are depicted using CAD computer programs, working with paper and classic materials is still very important.
