Design engineering is a collaborative and creative problem-solving process that transforms concept designs into tangible products. This  requires specialised knowledge and experience to ensure that the final product meets customer expectations, serves its intended purpose and can be manufactured profitably.

Examples of design engineering include building and civil infrastructure construction, industrial equipment design and consumer product design (US Site), and material manufacturing and processing. Jobs in design engineering could include industrial designer, mechanical, electrical or electronic engineer, simulation specialist, CAD designer and CAD drafter.

A design engineer uses mathematical principles, engineering physics, industry knowledge and specialist software to address problems and develop an idea from its conceptual stage to a detailed design. The detailed design must meet requirements and be delivered profitably and is communicated to stakeholders such as manufacturing and procurement via a computer-aided design (CAD) model, technical drawings, a "bill of materials" (BOM) and a specification. The engineering design development process is collaborative and can include multiple disciplines, including industrial design, mechanical, electrical and electronic engineering, and also includes feedback from customers, suppliers, manufacturing and project management.

Design engineering is crucial for successful product development businesses. The objective of design development is to imagine and agree on a product solution that benefits both customers and the business. Design development is constrained by budget, engineering capacity and time to market. The design engineering process is iterative and cyclical, with ideas undergoing multiple rounds of prototyping, testing, evaluation and review until the final design is considered optimal and reliable enough for production. The design engineering process starts by defining the problem, then brainstorming potential solutions before creating prototypes, testing them, gathering feedback and evaluating whether the problem statement can be further refined, and whether to reject or accept the proposed solutions, or whether the solutions can be improved with another development cycle.

Design and engineering software applications support product development by automating tasks and managing data. Examples of software for engineering design include product data management (PDM), product lifecycle management, computer-aided design (CAD) and computer-aided engineering (CAE).

The purpose of CAD software is to create a virtual 3D model of a product or machine design, along with its associated data such as technical drawings and bill of materials (BOM). Design engineers use a CAD model as the basis for computer-aided engineering (CAE), which is used to assess if the proposed solution will meet its intended purpose. CAE simulation software for engineering design includes finite element analysis (FEA) and computational fluid dynamics (CFD). CAD software is used to design almost everything you see around you, from roads and bridges, to buildings, to cars and aeroplanes, to your clothes, to the products you use every day, including the processing of your food and water and the generation of power.

Businesses that manufacture industrial and consumer goods feel the pressure of providing innovative solutions to meet customer demands and releasing them to market before their competition can. The key to successful product development lies in design engineering, which ensures that the products not only meet customer needs but also generate profit for the business. The decisions made during product development can affect the quality, components, materials, manufacturing processes and usability of the product over its lifecycle. Design engineering software like computer-aided design (CAD) and computer-aided engineering (CAE) benefit businesses and professionals by automating design processes and managing data insights, enabling designers and engineers to make timely and effective decisions that increase the success of the product, aid operational efficiency and improve time to market.

Design and engineering software aids product development teams by automating processes and managing data insights to reduce overall design development time while maintaining the quality of the process. Key features and functionality of CAD software for design engineering include:

• 3D modelling of parts and assemblies to conceptualise the physical dimensions and spatial relationships of the design.
• Specialist feature sets with associated CAD libraries to automate mechanical and electrical design (US Site) elements such as shafts and gears, bolted connexions, sheet metal, welds, structures, piping runs and electrical wire harnesses.
• Functionality to create 2D technical drawings or 3D model-based annotations to communicate accurate information for manufacturing, including materials, finishes, manufacturing techniques, dimensions and tolerances.
• Presentation and rendering tools to create photorealistic images and animations of the design to communicate assembly instructions or for sales and marketing materials.
• Simulation features to calculate stress, vibration or fluid flow, or generative design tools to automate the design of components based on loading conditions.
• Bill of material (BOM) management functionality to automatically create a list of components to be procured or manufactured, and to aid in the bulk ordering of raw materials.
• Software features to automate downstream manufacturing tasks such as nesting of components onto stock materials (US Site) or computer-aided manufacturing (CAM), including 3D printing (Additive manufacturing) and computer numerical control machining (CNC) (Subtractive manufacturing).
• CAD data and process management functionality to aid concurrent engineering, track tasks, audit information from design reviews, and manage engineering change orders.

Software applications in design and engineering aid in product development by automating tasks and data management. The data generated in design engineering plays a crucial role in subsequent activities during the product lifecycle, such as procurement, manufacturing, commissioning and support. It is important that the data created by design and engineering software applications is seamlessly integrated with other business systems.

Design and engineering software applications like computer-aided design (CAD) and computer-aided engineering (CAE) integrate with product data management (PDM) software to manage and control access to the files, ensuring that the right people have the right data at the right time. PDM software works alongside product lifecycle management (PLM) software to manage design and engineering processes such as new product introduction (NPI), bill of materials management (BOM), and quality control. CAD software also integrates with computer-aided manufacturing (CAM) software, which uses 2D and 3D CAD data to create computer numerical control (CNC) tool paths or slicing patterns for 3D printing. The integration of CAD and CAM with manufacturing execution systems (MES) (US Site) allows for efficient monitoring, tracking and control of the manufacturing processes. To propagate product design data where it is needed throughout the business, design and engineering software applications integrate with business systems such as materials requirements planning (MRP) or enterprise resource planning (ERP) software applications.
