Basic Drafting Tools

Drawing Table

• It is where the drawing paper is laid or fastened

Ruler

• A ruler, is an instrument used in geometry, technical drawing, printing, engineering and building to measure distances or to rule straight lines.

T - Square• T-square is a

technical drawing instrument used by draftsmen primarily as a guide for drawing horizontal lines on a drafting table. It may also guide a set square to draw vertical or diagonal lines.

Compass

• Compass is a technical drawing instrument that can be used for inscribing circles or arcs. also guide a set square to draw vertical or diagonal lines.

Triangle

• A thin, flat, right-angled piece of plastic or metal with acute angles of 45, or 30 and 60 used for drawing vertical or inclined lines that are multiples of 15

Protractor• A protractor is a

measuring instrument, typically made of transparent plastic or glass, for measuring angles. Most protractors measure angles in degrees (°)

French or Irregular Curve

• A French curve is a template usually made out of metal, wood or plastic composed of many different curves.

Eraser

Erasing Shield

• A metal plate with various slots and openings used to protect line work when a portion of the drawing is to be erased

• Never use the edge of T-square, ruler, protractor, and triangles to cut paper along its working edge.

Proper Care of Drafting Tools and Materials.

• Wipe off the surface and edges of your T-square, ruler, protractor, and triangles before and after using them.

• Avoid dropping your compass and technical pens.

• Wash the tips of your compass after using them.
