A protractor is a semicircular geometry tool divided into 180 equal parts, each measuring 1°. It is used for drawing angles of known measures and finding angles of unknown measures and is usually made of transparent plastic, glass, steel, or wood.

A triangular scale is a ruler that has a 3-lobed cross-section with 6 different types of scales on the edges (2 on each face) used for measuring and preparing scale drawings such as blueprints and maps. It is also called an architect's scale.

a straight strip or cylinder of plastic, wood, metal, or other rigid material, typically marked at regular intervals, to draw straight lines or measure distances.

Eraser, piece of rubber or other material used to rub out marks made by ink, pencil, or chalk. The modern eraser is usually a mixture of an abrasive such as fine pumice, a rubbery matrix such as synthetic rubber or vinyl, and other ingredients.

divider, instrument for measuring, transferring, or marking off distances, consisting of two straight adjustable legs hinged together and ending in sharp points. It is used principally in drafting for the accurate transfer of dimensions from a measuring scale and in machine shops for scribing lines on surfaces, usually machined, with dimensions taken from a ruler. A compass is essentially a divider in which one of the points has been replaced by a pencil or other marking device. The compass is useful for scribing circles or arcs of circles; it usually includes a scale to indicate the radius of the circle being scribed.

Drafting tape is coated with a weak adhesive and is mainly used to fix paper to drafting boards and to hold lettering, etc. while designing and doing layouts. It is also used to hold photographs and stencil templates in place on mounts and painting areas to check their positions.

a device used to make the tip of a pencil sharp so that it can be used for writing.

A pantograph (Greek roots παντ- "all, every" and γραφ- "to write", from their original use for copying writing) is a mechanical linkage connected in a manner based on parallelograms so that the movement of one pen, in tracing an image, produces identical movements in a second pen. If a line drawing is traced by the first point, an identical, enlarged, or miniaturized copy will be drawn by a pen fixed to the other. Using the same principle, different kinds of pantographs are used for other forms of duplication in areas such as sculpture, minting, engraving, and milling.

Because of the shape of the original device, a pantograph also refers to a kind of structure that can compress or extend like an accordion, forming a characteristic rhomboidal pattern. This can be found in extension arms for wall-mounted mirrors, temporary fences, pantographic knives, scissor lifts, and other scissor mechanisms such as the pantograph used on electric locomotives and trams.

Drawing paper is a heavier, and better-quality paper than sketching paper. It is commonly used for sketching and finished work. The ideal mediums used with drawing paper are graphite, charcoal, dry monochromes, soft pastel, oil pastel, markers and pen and ink

A marking gauge, also known as a scratch gauge, is used in woodworking and metalworking to mark out lines for cutting or other operations. The purpose of the gauge is to scribe a line parallel to a reference edge or surface. It is used in joinery and sheetmetal operations

Combining the functions of protractors and drafting triangles, adjustable triangles can be set and locked at any angle. The degrees of an angle, marked in half-degree increments, are found on the protractor portion and then locked in place. The triangle portion can then be used to draw the selected angle.
