What you'll do

Day-to-day tasks

As a CAD technician, you could:

  • read and interpret engineering plans and instructions
  • produce technical drawings and layouts, using 2D or 3D software
  • check that drawings meet quality and technical standards
  • find and fix inaccuracies or mistakes
  • work closely with engineers, designers and project staff
  • contribute to project meetings and presentations
  • keep accurate records and maintain different versions of your design work

Working environment

You could work in an office or on a construction site.

Career path and progression

With experience, you could become a CAD project co-ordinator or design team manager.

You could register with the Engineering Council to achieve Engineering Technician (EngTech) status. This would demonstrate your skills and expertise in your particular industry.

You might also be a freelance CAD designer, working for companies on different contracts.

What it takes

Skills and knowledge

You'll need:

  • design skills and knowledge
  • maths skills
  • to be thorough and pay attention to detail
  • knowledge of engineering science and technology
  • excellent verbal communication skills
  • thinking and reasoning skills
  • the ability to work well with others
  • the ability to use your initiative
  • to be able to use a computer and the main software packages confidently

Most relevant

  • Design and Technology - CAD technicians work at the heart of the design process, turning concepts into detailed technical drawings and layouts. Understanding materials, manufacturing methods, and how products and structures are put together is essential for creating designs that actually work in practice.
  • Mathematics - CAD technicians use maths constantly – calculating dimensions, tolerances, angles, and scales when producing technical drawings. Geometry and spatial reasoning are particularly important when working in 2D and 3D design environments.
  • Engineering - CAD technicians produce drawings for engineering projects across construction, manufacturing, and aerospace. Understanding engineering principles helps them interpret specifications, spot errors in designs, and communicate effectively with the engineers they work alongside.
  • Computer Science - CAD technicians spend their working day using complex design software to build and manipulate 2D and 3D models. Understanding how software works at a deeper level – including file structures, data management, and parametric modelling logic – helps them work more efficiently and troubleshoot technical issues.
  • Physics - CAD technicians need to understand how forces, loads, and materials behave so that the structures and components they draw will function safely in the real world. Concepts like stress, tension, and thermal expansion directly inform the technical decisions they make in their designs.

Also relevant

  • Art and Design - CAD technicians use visual skills like spatial awareness, proportion, and an eye for layout when creating technical drawings. A strong sense of visual communication helps them produce clear, well-organised designs that others can easily interpret.
  • Geography - CAD technicians working in construction often deal with site plans, land surveys, and topographical data. Understanding how landscapes, terrain, and environmental factors affect building design is useful when producing drawings for construction projects.
  • Business - CAD technicians often work freelance or progress into project coordination and team management roles. Understanding how to manage contracts, price work, and coordinate with clients is valuable – especially for those who want to run their own design consultancy.

How to become

You can get into this job through:

  • a university course
  • a college course
  • an apprenticeship

You could study for a higher national diploma or degree that includes computer-aided design work, such as:

  • construction
  • architectural technology
  • product design
  • design engineering
  • production or manufacturing engineering

Courses that include a year in industry or a summer internship will give you an opportunity to develop contacts and gain relevant work experience.

Entry requirements

You'll usually need:

  • 1 or 2 A levels, or equivalent, for a foundation degree or higher national diploma
  • 2 to 3 A levels, or equivalent, for a degree

More Information

You could train in computer-aided design by taking a college course like:

  • engineering technology
  • 2D computer-aided design
  • design and technology
  • T Level in Design, Surveying and Planning for Construction
  • T level in Design and Development for Engineering and Manufacturing

Entry requirements

Entry requirements for these courses vary.

  • 4 or 5 GCSEs at grades 9 to 4 (A* to C), or equivalent, including English and maths for a T Level

More Information

You could apply to do an apprenticeship that includes training in CAD design skills. These can be found in many industries, including engineering, manufacturing and construction.

Examples include:

  • Engineering and Manufacturing Support Technician Level 3 Advanced Apprenticeship
  • Engineering Design and Draughtsperson Level 3 Advanced Apprenticeship
  • Civil Engineering Senior Technician Level 4 Higher Apprenticeship
  • Construction Design and Build Technician Level 4 Higher Apprenticeship

Entry requirements

You'll usually need:

  • 5 GCSEs at grades 9 to 4 (A* to C), or equivalent, including English and maths, for an advanced apprenticeship
  • 4 or 5 GCSEs at grades 9 to 4 (A* to C) and A levels, or equivalent, for a higher or degree apprenticeship

Career tips

It can be useful to check job adverts to see which design software skills employers are looking for. Some software companies offer student packages or free trials that allow you to practise using them.

In construction design, it's helpful to have an understanding of Building Information Modelling (BIM).
