The computer-aided design (CAD) field is all about using special software to develop precise plans for making buildings, machines, and a wide range of other products.
Working in CAD means taking a concept for an object or structure, and creating detailed schematics and instructions for bringing it to life.
Computer-aided design has a huge range of applications. Through CAD training, you can develop skills that are valued in a wide variety of industries, including architecture, manufacturing, engineering, and more.
In this post, we explain what computer-aided design is, what it’s used for, and what kinds of career options are available in the field.
Curious about a career in CAD? Here’s what you need to know.
WHAT EXACTLY IS COMPUTER-AIDED DESIGN?
Computer-aided design is the process of digitally developing technical drawings, schematics, layouts, blueprints, models, manuals, and plans.
With CAD software, you can create 2D or 3D design documents with precise measurements. You can specify exactly what components are needed, how they will fit together, and how the final product should look.
Those detailed documents become the instructions for assembling and building anything from houses, factories, and furniture to fixtures, tools, and machines.
Industries like architecture, industrial design, manufacturing, engineering, and product design commonly rely on the skills and expertise of CAD specialists.
Every new project begins with a blueprint, drafted by a CAD professional. They play a crucial role in the design and creation process.
WHAT IS CAD USED FOR?
CAD software can be used to produce a wide variety of design documents. Here are a few common types:
☑️ Manufacturing blueprints
Manufacturing blueprints are detailed, precise plans that specify how an object should be constructed or fabricated. They provide information on dimensions, tolerances, material types, finishes, and more.
☑️ Floor plans
Floor plans map out the position of walls, doors, windows, furniture, and other components of a building. They show the size and layout of each room from a top-down view.
☑️ Site plans
Also known as plot plans, site plans are scaled drawings that outline how a piece of land will be altered or improved. They show what currently exists on the property and what changes are being proposed.
Site plans illustrate the placement of things like buildings, landscape features, power lines, driveways, parking lots, and fencing.
☑️ Piping and instrumentation diagrams
Piping and instrumentation diagrams (P&IDs) document the functional relationship of piping and other components in a process flow. They demonstrate how pumps, valves, drains, sensors, tanks, and related components connect and relate to each other.
A P&ID is often created when a manufacturing process is being developed for a physical plant.
☑️ Electrical schematics
Electrical schematics offer a high-level view of the makeup of an electrical system. They show the functionality of a circuit and how the various components relate to each other, but they don’t indicate how the wires are physically laid out.
☑️ Wiring diagrams
Wiring diagrams represent the actual location of wires within a circuit or electrical system. They illustrate how the wires connect to each other and to other fixtures and components.
WHAT CAREER PATHS ARE AVAILABLE IN COMPUTER-AIDED DESIGN?
CAD training can lead to a variety of different career paths.
For instance, you could specialize in architectural or civil design and drafting. This involves developing foundation, framing, and site plans along with drawings that show the layout of plumbing, HVAC, and electrical systems.
You could also focus on mechanical or manufacturing design and drafting. In this case, you would prepare drawings, models, and specifications for tools, devices, machines, assemblies, parts, and equipment.
CAD specialists are hired by:
☑️ Architecture firms
☑️ Design firms
☑️ Manufacturing companies
☑️ Land surveyors
☑️ Government departments☑️ Utility companies
Herzing College CAD instructor Roberto Romano says the computer-aided design and drafting field offers plenty of ways to advance.
“Most graduates start out as junior CAD designers/drafters. This work usually involves doing corrections to drawings, preparing shop drawings in AutoCAD, and converting files over.
A junior designer is often responsible for answering client emails and calls, keeping clients updated on projects, maintaining logs, bills of materials, and other documentation.
If you do the work well, and your employer appreciates your efficiency and work ethic, there are definitely ways to move up.
A junior drafter can get promoted to senior drafter, and even transfer into the design department.”
WHAT ARE SALARIES LIKE IN THE CAD FIELD?
Working in computer-aided design can come with a healthy income.
According to the Government of Canada Job Bank, CAD technicians in Quebec have a median salary of about $52,000.
The highest-earning CAD specialists in the province make upwards of $74,000.
