In the constantly changing engineering field, innovation and problem-solving are essential for progress. Over the past 30 years, one technology that has profoundly reshaped the engineering landscape is Computer-Aided Design (CAD). This technology has revolutionised how engineers conceptualise, design, and analyse their projects. In this blog, we will explore CAD design in-depth, examining its significance, core aspects, and the indispensable role it plays in engineering projects.
The Importance of CAD Design in Engineering
In today's world, where precision and efficiency are paramount, CAD Design is a cornerstone of modern engineering. CAD, or Computer-Aided Design, involves computer software to create detailed 2D technical drawings and 3D models of physical objects. These models serve as visual guides for engineers, architects, and designers throughout the product development process. With CAD, relying solely on paper sketches and manual drafting to communicate ideas is a thing of the past, replaced by a new era of accuracy, speed, and design flexibility. At Twenty20 Engineering, CAD is fundamental to delivering high-quality projects or products to our clients, as it is used in some form at every stage of our projects.
Why Understanding CAD Design Matters
Understanding CAD design isn't just about mastering technology; it's a foundational requirement for anyone in the engineering field. At Twenty20 Engineering, all our team members undergo formal training in multiple CAD software types, ensuring a diverse skill set to deliver projects effectively. In the current digital design environment, proficiency in CAD tools is essential for engineers to maintain competitiveness and efficiency. Proficiency in CAD facilitates smooth communication among team members, clients, and stakeholders. It acts as a bridge between conceptual sketches and tangible prototypes, enhancing overall project efficiency.
The Fundamentals of CAD Design
At its essence, CAD is a technology leveraging computer hardware and software to assist in creating, modifying, analysing, or optimising designs or engineering projects. It boosts designer productivity, enhances design quality, establishes manufacturing databases, and aids in simulations and analyses. CAD software applications are diverse, catering to various industries such as:
The Evolution of CAD: From Paper to Pixels
Before CAD became the sophisticated tool it is today, design engineers and architects relied heavily on manual drafting techniques. As discussed in our previous blog, "From Sketch to Perfection: How CAD and Design Refines Your Concepts," manual sketches and drafting remain valuable tools in a designer's arsenal during the ideation and conceptualisation phases of a project. Indeed, many projects originate as basic sketches on paper.
Once a concept has been agreed upon, CAD accelerates the project by transforming it into an accurate 3D model, serving as a virtual prototype. This reduces reliance on sketching and manual drafting, minimising labour, time, and errors in the design process. The evolution of CAD has significantly streamlined design processes, with computer-based drafting tools enabling engineers to create intricate and complex products easily. This efficiency is evident in the reduced time to market for all products, especially Fast-Moving Consumer Products (FMCP) like the Apple iPhone.
The Role of CAD Design in Engineering
CAD smoothly integrates into the engineering workflow for all projects, serving as a cornerstone of the design process. It holds significance from the project's conception to its completion. Once the CAD model and 2D technical drawings are completed, additional manufacturing data can be generated, including a Bill of Materials (BOM), part schedules, assembly instructions, and buildability guidelines. Moreover, it can produce specific file formats tailored for 3D printing, laser cutting, and sheet metal bending.
Benefits of CAD Design in Engineering Projects
The advantages of CAD Design in engineering projects are manifold. Firstly, CAD enhances productivity by streamlining the design process.

Design files can be easily shared and modified in various formats, facilitating stakeholder input and feedback. This collaborative environment nurtured by Twenty20 Engineering encourages creativity and innovation, enabling the development of cutting-edge products.
The CAD Design Process Unveiled
The CAD design process begins by outlining the project scope and specifications, which entails collecting input from clients and stakeholders. Engineers delve into the project's objectives, functional requirements, budget limitations, and desired timeline. By delineating design constraints and parameters, engineers lay the groundwork for the subsequent stages of the design process.
Once the project scope is established, engineers transition to the conceptualisation phase, as discussed in our blog "Sketch to Perfection: How CAD and Design Refines Your Concepts." This phase encompasses manual sketching, drafting, brainstorming, and creative workshops. Engineers explore diverse possibilities, generating multiple design solutions to meet project objectives. These ideas are subsequently refined and narrowed down to a final concept.
After establishing conceptual designs and sketches, the subsequent phase entails 3D CAD modelling, transitioning the idea from paper to a virtual prototype by elaborating on the 2D sketch into a detailed 3D model. Engineers used CAD software to craft three-dimensional representations of the product or structure, necessitating profound comprehension of engineering, geometry, and spatial relationships. With careful attention to detail, engineers design the components to ensure precision and accuracy. 3D modelling minimises design errors like clashes and tolerance issues, facilitating necessary adjustments before advancing further.
Step 4: Analysis and Simulation
After the 3D model is created, engineers conduct comprehensive simulations to assess the performance and feasibility of a part or assembly. Advanced CAD software allows for such simulations as stress analysis, fluid dynamics, thermal analysis and cyclic/dynamic loading. Engineers can then evaluate the data provided and identify potential weaknesses or areas that require improvement.
The CAD and design process is inherently iterative. Engineers evaluate simulation data to refine the design, making necessary iterations to address the shortcomings. Continuous improvement is paramount, with engineers collaborating closely to discuss potential solutions and enhancements. This iterative process persists until the design achieves an optimal state, prepared for creating the 2D technical drawings and manufacturing data.
Once the design undergoes analysis and the 3D models are checked and approved, our engineers develop detailed 2D technical drawings, manufacturing data, and production schedules. These technical drawings include essential dimensions, tolerances, and annotations to convey the design intent to the manufacturing and production teams. The information outlined in the 2D technical drawings, schedules, bills of materials (BOM), and assembly instructions serves as the foundation for the successful manufacturing of the product.
