Computer-aided Design (CAD)

Computer-aided design (CAD) is a form of design with which people work with computers to create ideas, models, and prototypes. CAD was originally developed to assist people with technical drawing and drafting, but it has expanded to include numerous other potential utilities. A variety of software products designed for CAD can be found on the market, with many being targeted to a specific application or industry.

Computer-aided design (CAD), also known as Computer-aided design and drafting (CADD), is the use of computer technology for the process of design and design-documentation. Computer-aided drafting describes the process of drafting with a computer. CAD software, or environment, provides the user with input-tools for the purpose of streamlining design processes; drafting, documentation, and manufacturing processes.

CAD environments often involve more than just shapes. As in the manual drafting of technical and engineering drawings, the output of CAD must convey information, such as materials, processes, dimensions, and tolerances, according to application-specific conventions.

CAD may be used to design curves and figures in two-dimensional (2D) space; or curves, surfaces, and solids in three-dimensional (3D) objects.

CAD Applications

CAD is an important industrial art extensively used in many applications, including automotive, shipbuilding, and aerospace industries, industrial and architectural design, prosthetics, and many more.

It's a process in which someone creates documents containing technical drawings that precisely convey the specifications and materials needed to create something, whether it's a building or a cellular phone. While today's drafting uses advanced computer technology, drafting has existed since ancient times.

Drafting is the drawing of objects to scale, usually a top view, main view and side view, to tell a machinist the specifications of what he will be making, what it looks like, and what dimensions and special work will be required or needed to make it. Often such drawings are made into blue prints, which have white lines on a blue background.

Example: Architectural drawings are also drafted, and they show the dimensions of the house, the size and shape of the rooms, and where they are in it. They show the house's built- in appliances, its features such as bathrooms, laundry rooms, cellars, upper stories, the types and sizes of doors and windows, etc, that will be needed, as well as well as specifications for drive ways, type of roof(s), maps, acreage of the lot, fences, zoning, etc should be.


In 3D computer graphics, 3D modellingis the process of developing a mathematical, wireframe representation of any three-dimensional object (either inanimate or living) via specialized software. The product is called a 3D model.

3D models are most often created with special software applications called 3D modellers when not describing the title of a professional who uses the software to produce 3D models. 3D models are widely used anywhere where 3D graphics are used. Actually, their use predates the widespread use of 3D graphics on personal computers. Many computer games used pre-rendered images of 3D models as sprites before computers could render them in real-time. Examples: Today, 3D models are used in a wide variety of fields. The medical industry uses detailed models of organs. The movie industry uses them as characters and objects for animated and real-life motion pictures. The video game industry uses them as assets for computer and video games. The science sector uses them as highly detailed models of chemical compounds. The architecture industry uses them to demonstrate proposed buildings and landscapes. The engineering community uses them as designs of new devices, vehicles and structures as well as a host of other uses. In recent decades the earth science community has started to construct 3D geological models as a standard practice.

Engineering Analysis

Concurrent Design provides Engineering Analysis as an integral part of many projects or as an independent service. By analysing the design carefully, the design can be optimized for geometry, weight, structure, function, thermal efficiency, vibration and safety. With numerous registered Professional Engineers on staff and a strong suite of tools, Concurrent Design can optimize your product and assure its' safety.

Finite Element Analysis

FEA consists of a computer model of a material or design that is stressed and analysed for specific results. It is used in new product design, and existing product refinement. A company is able to verify a proposed design will be able to perform to the client's specifications prior to manufacturing or construction. Modifying an existing product or structure is utilized to qualify the product or structure for a new service condition. In case of structural failure, FEA may be used to help determine the design modifications to meet the new condition.

There are generally two types of analysis that are used in industry: 2-D Modelling, and 3-D Modelling. While 2-D modellingconserves simplicity and allows the analysis to be run on a relatively normal computer, it tends to yield less accurate results. 3-D Modelling, however, produces more accurate results while sacrificing the ability to run on all but the fastest computers effectively. Within each of these modellingschemes, the programmer can insert numerous algorithms (functions) which may make the system behave linearly or non-linearly. Linear systems are far less complex and generally do not take into account plastic deformation. Non-linear systems do account for plastic deformation, and many also are capable of testing a material all the way to fracture.

Finite Element Methods

The finite element method is one of the most powerful approaches for approximate solutions to a wide range of problems in mathematical physics. The method has achieved acceptance in nearly every branch of engineering and is the preferred approach in structural mechanics and heat transfer. Its application has extended to soil mechanics, heat transfer, fluid flow, magnetic field calculations, and other areas.


A variety of specializations under the umbrella of the mechanical engineering discipline (such as aeronautical, biomechanical, and automotive industries) commonly use integrated FEM in design and development of their products. Several modern FEM packages include specific components such as thermal, electromagnetic, fluid, and structural working environments. In a structural simulation, FEM helps tremendously in producing stiffness and strength visualizations and also in minimizing weight, materials, and costs.

FEM allows detailed visualization of where structures bend or twist, and indicates the distribution of stresses and displacements. FEM software provides a wide range of simulation options for controlling the complexity of both modellingand analysis of a system. Similarly, the desired level of accuracy required and associated computational time requirements can be managed simultaneously to address most engineering applications. FEM allows entire designs to be constructed, refined, and optimized before the design is manufactured.

Computer-aided Manufacturing (CAM)

Computer-aided manufacturing takes this one step further by bridging the gap between the conceptual design and the manufacturing of the finished product. Whereas in the past it would be necessary for a design developed using CAD software to be manually converted into a drafted paper drawing detailing instructions for its manufacture, Computer-aided Manufacturing software allows data from CAD software to be converted directly into a set of manufacturing instructions.

CAM software converts 3D models generated in CAD into a set of basic operating instructions written in G-Code. G-code is a programming language that can be understood by numerical controlled machine tools - essentially industrial robots - and the G-code can instruct the machine tool to manufacture a large number of items with perfect precision and faith to the CAD design.

Benefits of Computer-aided manufacturing

While undesirable for factory workers, the ideal state of affairs for manufacturers is an entirely automated manufacturing process. In conjunction with Computer-aided Design, Computer-aided Manufacturing enables manufacturers to reduce the costs of producing goods by minimizing the involvement of human operators.

In addition to lower running costs there are several additional benefits of using CAM software. By removing the need to translate CAD models into manufacturing instructions through paper drafts, it enables manufactures to make quick alterations to the product design, feeding updated instructions to the machine tools and seeing instant results.

In addition, many CAM software packages have the ability to manage simple tasks such as the re-ordering of parts, further minimizing human involvement. Though all numerical controlled machine tools have the ability to sense errors and automatically shut down, many can actually send a message to their human operators via mobile phones or e-mail, informing them of the problem and awaiting further instructions.

Computer-aided Engineering (CAE)

CAE (Computer-aided engineering) is a broad term used by the Electronic Design Automation (EDA) industry for the use of computers to design, analyze, and manufacture products and processes.

CAE includes :

  • CAD (Computer-aided design) - the use of a computer for drafting and modellingdesigns, and
  • CAM (Computer-aided manufacturing) - the use of computers for managing manufacturing processes.

Software tools that have been developed to support these activities are considered as CAE tools. CAE tools are being used, for example, to analysethe robustness and performance of components and assemblies. The term encompasses simulation, validation, and optimization of products and manufacturing tools.

In the future, CAE systems will be major providers of information to help support design teams in decision making.

CAE systems can provide support to businesses. This is achieved by the use of reference architectures and their ability to place information views on the business process.

The term CAE has also been used by some in the past to describe the use of computer technology within engineering in a broader sense than just engineering analysis.

Project Planning and Management (PPM)

Here is the main definition of what project management is :

  • Project management is no small task.
  • Project management has a definite beginning and end. It is not a continuous process.
  • Project management uses various tools to measure accomplishments and track project tasks. These include Work Breakdown Structures, Gantt charts and PERT charts.
  • Projects frequently need resources on an ad-hoc basis as opposed to organizations that have only dedicated full-time positions.
  • Project management reduces risk and increases the chance of success.
  • Project management is often summarized in a triangle. The three most important factors are time, cost and scope, commonly called the triple constraint. These form the vertices with quality as a central theme.
  • Projects must be delivered on time.
  • Projects must be within cost.
  • Projects must be within scope.
  • Projects must meet customer quality requirements.
