CAD stands for Computer-Aided Design and is the overarching term for using computer software to design a whole range of things. Computer-aided design (CAD) technicians use their engineering, IT, and mathematical knowledge and skills to design buildings, machinery, products, and parts.

In this post, Pritish Kumar gives refers to some of the most common interview questions for a Computer Aid Design Technician along with an appropriate answer.

They create electronic design plans for buildings and machinery using computer software. CAD technicians work together with building architects and professional draftsmen to turn blueprints and technical drawings into 2D and 3D computer models.

The plans created by drafters are employed by many different industries. For example, architectural and civil drafters work in construction and draw up outlines for buildings, highways, pipelines, and more. Mechanical, electrical and electronics drafters create plans for circuitry and equipment. Drafters are also used in the aeronautical industry, where they design aircraft, missiles, and the like. The U.S. Bureau of Labor Statistics (BLS) forecasts drafting jobs to decline by 4% between 2019 and 2029 (

Computer Aid Design Technician Interview: the Basics

To ensure success as a CAD technician, you should have extensive working experience with CAD software. Need a keen eye for detail, and the ability to work as part of a team. A top-class CAD technician is a technical wizard, creating exact computer models of building and machine designs according to the client’s specifications.

There are two types of work in the job, designing in 2D (known as surface modeling) and in 3D, (known as solid modeling). There are numerous ways into the profession – the first of which is an apprenticeship with an Engineering firm. To access this, however, you will need at least 4/5 GCSEs at A to C level, more than likely including Maths and Science.

A degree is not a prerequisite for entry to a CAD technician/draughts person role but it can provide relevant engineering and technical knowledge.  Relevant degrees include all engineering disciplines, architecture, manufacturing, IT and design, and other engineering roles such as design engineer, civil engineer, and architectural professions.
