They are also involved in related activities such as estimating, contract administration as well as specification preparation and interpretation. CAD operators may also prepare a technical report to accompany the CAD drawings.ĬAD operators use a number of sources and aids to assist them in their drafting and design work, such as data tables, calculators and computers. Their drawings indicate the details of products and structures, specify materials to be used and procedures to be followed. Using industry standards and regulations, they make calculations and prepare design drawings using preliminary concepts, sketches, calculations, specifications and other data. They utilise knowledge of various CAD programs, machines, engineering practices, mathematics, building materials and other physical sciences to complete drawings.

CAD operators use computer-aided design systems and peripheral equipment to draft and modify drawings which vary from rough or detailed sketches or notes to specified dimensions for manufacturing, construction, engineering, or other purposes. CAD operators support the work of engineers and architects by developing and preparing the engineering designs and technical drawings used to build everything from mechanical products to structures. Structures are carefully designed by a team of engineers assisted by computer aided drafting (CAD) operators.

CAD software is used to enable the technician to visualise the structure and function of an item, as well as indicating what colour and texture are to be used to fill in the shape.Įvery physical structure or object created in recent years - from hand-blenders to skyscrapers - has a set of design or drafting diagrams applicable to it.

Parts of the drawing can be shown in 3D and they can be annotated. The drawings are high resolution (the degree of detail visible in an image or photograph), easy to correct, and can be shifted or rotated to any perspective. A computer-aided drafting or design technician creates detailed design drawings using computer-aided drafting (CAD) software.
