CADD software

The computer-aided design and drafting (CADD) is the use of computer technology for design and design documentation. CAD software replaces manual drafting with an automated process.

CADD software should be differentiated from computer-aided design (CAD) software. CADD systems are CAD systems with additional drafting features enabling the user to insert size annotations and other notes into a design.

cross-sector

CADD software is an essential knowledge of the following occupations:

Engraving machine operator: Engraving machine operators set up, programme, and tend engraving machines designed to precisely carve a design in the surface of a metal workpiece by a diamond stylus on the mechanical cutting machine that creates small, separate printing dots existing from cut cells. They read engraving machine blueprints and tooling instructions, perform regular machine maintenance, and make adjustments to the precise engraving controls, such as the depth of the incisions and the engraving speed.
Aerospace engineering drafter: Aerospace engineering drafters convert the aerospace engineers’ designs into technical drawings usually using computer-aided design programs. Their drawings detail dimensions, fastening and assembling methods and other specifications used in the manufacture of aircrafts and spacecrafts.
Marine engineering drafter: Marine engineering drafters convert the marine engineers’ designs into technical drawings usually using software. Their drawings detail dimensions, fastening and assembling methods and other specifications used in the manufacture of all types of boats from pleasure crafts to naval vessels, including submarines.
Architectural drafter: Architectural drafters make drawings of the specifications and ideas provided by architects. They draw architectural drawings using computer-aided equipment and software, or using conventional methods like paper and pen.
Lathe and turning machine operator: Lathe and turning machine operators set up, program and tend lathe and turning machines designed to cut excess metal from a metal workpiece using a hardened cutting tool moved by computer-controlled motors. They read lathe and turning machine blueprints and tooling instructions, perform regular machine maintenance, and make adjustments to the lathe controls, such as the depth of cuts and the rotation speed.
Drilling machine operator: Drilling machine operators set up, program and control drilling machines, designed to drill holes in workpieces using a computer-controlled, rotary-cutting, multipointed cutting tool, inserted into the workpiece axially. They read drilling machine blueprints and tooling instructions, perform regular machine maintenance, and make adjustments to the drilling controls, such as the depth of drills or the rotation speed.

CADD software is optional for these occupations. This means knowing this knowledge may be an asset for career advancement if you are in one of these occupations.

Grinding machine operator: Grinding machine operators set up, program and control grinding machines, designed to apply abrasive processes in order to remove small amounts of excess material and smoothen metal workpieces by using an abrasive wheel with diamond teeth as a cutting device for very precise and light cuts. They read grinding machine blueprints and tooling instructions, perform regular machine maintenance, and make adjustments to the grinding controls, such as the depth of cuts and the rotation speed.
Automotive designer: Automotive designers create model designs in 2D or 3D and prepare isometric drawings and graphics. They also conduct research collecting data about (new) materials, market trends and production processes.
Water jet cutter operator: Water jet cutter operators set up and operate a water jet cutter, designed to cut excess material from a metal workpiece by using a high-pressure jet of water, or an abrasive substance mixed with water.
Mechanical engineering drafter: Mechanical engineering drafters convert mechanical engineers’ designs and sketches into technical drawings detailing dimensions, fastening and assembling methods and other specifications used for example in manufacturing processes.
Automotive engineering technician: Automotive engineering technicians work with automotive engineers to operate, repair, maintain and test equipment used in motor vehicles. In some environments, such as an airport they are responsible for keeping equipment and vehicles serviceable. They review blueprints and designs to determine test specifications and procedures. Automotive engineering technicians use software to make sure that parts of a motor vehicle are functioning properly. They record test procedures and results, and make recommendations for changes.
3D printing technician: 3D Printing technicians assist in the designing and programming of products, ranging from prosthetic products to 3D miniatures. They may also provide 3D printing maintenance, check 3D renders for customers and run 3D printing tests. 3D printing technicians can also repair, maintain and clean 3D printers.
Industrial robot controller: Industrial robot controllers operate and monitor industrial robots used in automation processes to perform various manufacturing activities such as lifting, welding and assembling. They ensure that the machines are working correctly and in sync with other industrial robots, maintain and repair defective parts, assess risks and perform tests.
Printed circuit board designer: Printed circuit board designers diagram and design the construction of circuit boards. They envision the logical placing of conductive tracks, coppers, and pin pads in the board. They use computer programmes and specialised software for the designs.
Milling machine operator: Milling machine operators set up, program and control milling machines, designed to cut excess material from metal workpieces using a computer-controlled rotary-cutting, milling cutter. They read milling machine blueprints and tooling instructions, perform regular machine maintenance, and make adjustments to the milling controls, such as the depth of cuts or the rotation speed.
Drafter: Drafters prepare and create technical drawings using a special software or manual techniques, to show how something is built or works.
Laser cutting machine operator: Laser cutting machine operators set up, program and tend laser cutting machines, designed to cut, or rather burn off and melt, excess material from a metal workpiece by directing a computer-motion-controlled powerful laser beam through laser optics. They read laser cutting machine blueprints and tooling instructions, perform regular machine maintenance, and make adjustments to the milling controls, such as the intensity of the laser beam and its positioning.
Avionics technician: Avionics technicians install, test, inspect and adjust electrical and electronic equipment such as navigation, communication and flight control systems in aircraft and spacecraft. They carry out maintenance and repair work. They perform functional tests, diagnose problems and take corrective action.
Interior architect: Interior architects create plans of the interior of a home, building or other structure. They determine the specifications and distribution of the space. Interior architects combine an understanding of space with a sense for aesthetics in order to create a harmonious interior design. They draw architectural drawings using computer-aided equipment and software, or using conventional methods like paper and pen.
