Some of the most important documents used in the workplace are the technical drawings, diagrams, and schematics that specify how fabrication and construction tasks will be carried out, or describe the composition and assembly of equipment. One of the essential skills for anyone involved in a trade is the ability to correctly interpret drawings. If you are in a construction or fabrication industry, you will need to be able to examine a drawing, take information from it, and visualize the finished product. If you are in a service or maintenance industry, you will need to interpret exploded drawings in order to properly repair or assemble equipment.
